Through an enormous experimental \neffort1–4, the structures of around 100,000 unique proteins have been determined5, but \nthis represents a small fraction of the billions of known protein sequences6,7. Structural \ncoverage is bottlenecked by the months to years of painstaking effort required to \ndetermine a single protein structure. Accurate computational approaches are needed \nto address this gap and to enable large-scale structural bioinformatics. Predicting the \nthree-dimensional structure that a protein will adopt based solely on its amino acid \nsequence—the structure prediction component of the ‘protein folding problem’8—has \nbeen an important open research problem for more than 50 years9. Despite recent \nprogress10–14, existing methods fall far short of atomic accuracy, especially when no \nhomologous structure is available. Here we provide the first computational method \nthat can regularly predict protein structures with atomic accuracy even in cases in which \nno similar structure is known. We validated an entirely redesigned version of our neural \nnetwork-based model, AlphaFold, in the challenging 14th Critical Assessment of protein \nStructure Prediction (CASP14)15, demonstrating accuracy competitive with \nexperimental structures in a majority of cases and greatly outperforming other \nmethods. Underpinning the latest version of AlphaFold is a novel machine learning \napproach that incorporates physical and biological knowledge about protein structure, \nleveraging multi-sequence alignments, into the design of the deep learning algorithm.\nThe development of computational methods to predict \nthree-dimensional (3D) protein structures from the protein sequence \nhas proceeded along two complementary paths that focus on either the \nphysical interactions or the evolutionary history. The physical interac-\ntion programme heavily integrates our understanding of molecular \ndriving forces into either thermodynamic or kinetic simulation of pro-\ntein physics16 or statistical approximations thereof17. Although theoreti-\ncally very appealing, this approach has proved highly challenging for \neven moderate-sized proteins due to the computational intractability \nof molecular simulation, the context dependence of protein stability \nand the difficulty of producing sufficiently accurate models of protein \nphysics. The evolutionary programme has provided an alternative in \nrecent years, in which the constraints on protein structure are derived \nfrom bioinformatics analysis of the evolutionary history of proteins, \nhomology to solved structures18,19 and pairwise evolutionary correla-\ntions20–24. This bioinformatics approach has benefited greatly from \nthe steady growth of experimental protein structures deposited in \nthe Protein Data Bank (PDB)5, the explosion of genomic sequencing \nand the rapid development of deep learning techniques to interpret \nthese correlations. Despite these advances, contemporary physical \nand evolutionary-history-based approaches produce predictions that \nare far short of experimental accuracy in the majority of cases in which \na close homologue has not been solved experimentally and this has \nlimited their utility for many biological applications.\nIn this study, we develop the first, to our knowledge, computational \napproach capable of predicting protein structures to near experimental \naccuracy in a majority of cases. The neural network AlphaFold that we \ndeveloped was entered into the CASP14 assessment (May–July 2020; \nentered under the team name ‘AlphaFold2’ and a completely different \nmodel from our CASP13 AlphaFold system10). The CASP assessment is \ncarried out biennially using recently solved structures that have not \nbeen deposited in the PDB or publicly disclosed so that it is a blind test \nhttps://doi.org/10.1038/s41586-021-03819-2\nReceived: 11 May 2021\nAccepted: 12 July 2021\nPublished online: 15 July 2021\nOpen access\n Check for updates\n1DeepMind, London, UK. 2School of Biological Sciences, Seoul National University, Seoul, South Korea. 3Artificial Intelligence Institute, Seoul National University, Seoul, South Korea. 4These \nauthors contributed equally: John Jumper, Richard Evans, Alexander Pritzel, Tim Green, Michael Figurnov, Olaf Ronneberger, Kathryn Tunyasuvunakool, Russ Bates, Augustin Žídek, Anna \nPotapenko, Alex Bridgland, Clemens Meyer, Simon A.

AlphaFold structures had a median backbone \naccuracy of 0.96 Å r.m.s.d.95 (Cα root-mean-square deviation at 95% \nresidue coverage) (95% confidence interval = 0.85–1.16 Å) whereas \nthe next best performing method had a median backbone accuracy \nof 2.8 Å r.m.s.d.95 (95% confidence interval = 2.7–4.0 Å) (measured on \nCASP domains; see Fig. 1a for backbone accuracy and Supplementary \nFig. 14 for all-atom accuracy). As a comparison point for this accuracy, \nthe width of a carbon atom is approximately 1.4 Å. In addition to very \naccurate domain structures (Fig. 1b), AlphaFold is able to produce \nhighly accurate side chains (Fig. 1c) when the backbone is highly accu-\nrate and considerably improves over template-based methods even \nwhen strong templates are available. The all-atom accuracy of Alpha-\nFold was 1.5 Å r.m.s.d.95 (95% confidence interval = 1.2–1.6 Å) compared \nwith the 3.5 Å r.m.s.d.95 (95% confidence interval = 3.1–4.2 Å) of the best \nalternative method. Our methods are scalable to very long proteins with \naccurate domains and domain-packing (see Fig. 1d for the prediction \nof a 2,180-residue protein with no structural homologues). Finally, the \nmodel is able to provide precise, per-residue estimates of its reliability \nthat should enable the confident use of these predictions.\nWe demonstrate in Fig. 2a that the high accuracy that AlphaFold dem-\nonstrated in CASP14 extends to a large sample of recently released PDB \nstructures; in this dataset, all structures were deposited in the PDB after \nour training data cut-off and are analysed as full chains (see Methods, \nSupplementary Fig. 15 and Supplementary Table 6 for more details). \nFurthermore, we observe high side-chain accuracy when the back-\nbone prediction is accurate (Fig. 2b) and we show that our confidence \nmeasure, the predicted local-distance difference test (pLDDT), reliably \npredicts the Cα local-distance difference test (lDDT-Cα) accuracy of the \ncorresponding prediction (Fig. 2c). We also find that the global super-\nposition metric template modelling score (TM-score)27 can be accu-\nrately estimated (Fig. 2d). Overall, these analyses validate that the high \naccuracy and reliability of AlphaFold on CASP14 proteins also transfers \nto an uncurated collection of recent PDB submissions, as would be \nexpected (see Supplementary Methods 1.15 and Supplementary Fig. 11 \nfor confirmation that this high accuracy extends to new folds).\nThe AlphaFold network\nAlphaFold greatly improves the accuracy of structure prediction by \nincorporating novel neural network architectures and training proce-\ndures based on the evolutionary, physical and geometric constraints \nof protein structures. In particular, we demonstrate a new architecture \nto jointly embed multiple sequence alignments (MSAs) and pairwise \nfeatures, a new output representation and associated loss that enable \naccurate end-to-end structure prediction, a new equivariant attention \na\nG427\nAlphaFold\nG009\nG473\nG129\nG403\nG032\nG420\nG480\nG498\nG488\nG368\nG324\nG362\nG253\nG216\n0\n1\n2\n3\n4\nMedian Cα r.m.s.d.95 (Å)\nb\nC terminus\nN terminus\nAlphaFold\nExperiment\nr.m.s.d.95 = 0.8 Å; TM-score = 0.93\nc\nAlphaFold\nExperiment\nr.m.s.d. = 0.59 Å within 8 Å of Zn\nd\nAlphaFold\nExperiment\nr.m.s.d.95 = 2.2 Å; TM-score = 0.96\nMSA\n3D structure\nLow \nconfidence\nHigh \nconfidence\nTemplates\nInput sequence\nMSA \nrepresentation\n(s,r,c)\nEvoformer \n(48 blocks)\nStructure \nmodule\n (8 blocks)\n+\n+\n← Recycling (three times)\nPairing\nPair \nrepresentation\n(r,r,c)\nPair \nrepresentation\n(r,r,c)\nGenetic \ndatabase\nsearch\nStructure \ndatabase\nsearch\ne\nSingle repr.

A description of the most important ideas and components \nis provided below. The full network architecture and training procedure \nare provided in the Supplementary Methods.\nThe network comprises two main stages. First, the trunk of the net-\nwork processes the inputs through repeated layers of a novel neural \nnetwork block that we term Evoformer to produce an Nseq × Nres array \n(Nseq, number of sequences; Nres, number of residues) that represents \na processed MSA and an Nres × Nres array that represents residue pairs. \nThe MSA representation is initialized with the raw MSA (although \nsee Supplementary Methods 1.2.7 for details of handling very deep \nMSAs). The Evoformer blocks contain a number of attention-based \nand non-attention-based components. We show evidence in ‘Interpret-\ning the neural network’ that a concrete structural hypothesis arises \nearly within the Evoformer blocks and is continuously refined. The key \ninnovations in the Evoformer block are new mechanisms to exchange \ninformation within the MSA and pair representations that enable direct \nreasoning about the spatial and evolutionary relationships.\nThe trunk of the network is followed by the structure module that \nintroduces an explicit 3D structure in the form of a rotation and transla-\ntion for each residue of the protein (global rigid body frames). These \nrepresentations are initialized in a trivial state with all rotations set to \nthe identity and all positions set to the origin, but rapidly develop and \nrefine a highly accurate protein structure with precise atomic details. \nKey innovations in this section of the network include breaking the \nchain structure to allow simultaneous local refinement of all parts of \nthe structure, a novel equivariant transformer to allow the network to \nimplicitly reason about the unrepresented side-chain atoms and a loss \nterm that places substantial weight on the orientational correctness \nof the residues. Both within the structure module and throughout \nthe whole network, we reinforce the notion of iterative refinement \nby repeatedly applying the final loss to outputs and then feeding the \noutputs recursively into the same modules. The iterative refinement \nusing the whole network (which we term ‘recycling’ and is related to \napproaches in computer vision28,29) contributes markedly to accuracy \nwith minor extra training time (see Supplementary Methods 1.8 for \ndetails).\nEvoformer\nThe key principle of the building block of the network—named Evo-\nformer (Figs. 1e, 3a)—is to view the prediction of protein structures \nas a graph inference problem in 3D space in which the edges of the \ngraph are defined by residues in proximity. The elements of the pair \nrepresentation encode information about the relation between the \nresidues (Fig. 3b). The columns of the MSA representation encode the \nindividual residues of the input sequence while the rows represent \nthe sequences in which those residues appear. Within this framework, \nwe define a number of update operations that are applied in each block \nin which the different update operations are applied in series.\nThe MSA representation updates the pair representation through an \nelement-wise outer product that is summed over the MSA sequence \ndimension. In contrast to previous work30, this operation is applied \nwithin every block rather than once in the network, which enables the \ncontinuous communication from the evolving MSA representation to \nthe pair representation.\nWithin the pair representation, there are two different update pat-\nterns.

On the basis of this intuition, we \narrange the update operations on the pair representation in terms of \ntriangles of edges involving three different nodes (Fig. 3c). In particular, \nwe add an extra logit bias to axial attention31 to include the ‘missing edge’ \nof the triangle and we define a non-attention update operation ‘triangle \nmultiplicative update’ that uses two edges to update the missing third \nedge (see Supplementary Methods 1.6.5 for details). The triangle multipli-\ncative update was developed originally as a more symmetric and cheaper \nreplacement for the attention, and networks that use only the attention or \nmultiplicative update are both able to produce high-accuracy structures. \nHowever, the combination of the two updates is more accurate.\nWe also use a variant of axial attention within the MSA representation. \nDuring the per-sequence attention in the MSA, we project additional \nlogits from the pair stack to bias the MSA attention. This closes the loop \nby providing information flow from the pair representation back into \nthe MSA representation, ensuring that the overall Evoformer block is \nable to fully mix information between the pair and MSA representations \nand prepare for structure generation within the structure module.\n \nEnd-to-end structure prediction\nThe structure module (Fig. 3d) operates on a concrete 3D backbone \nstructure using the pair representation and the original sequence row \n(single representation) of the MSA representation from the trunk. The \n3D backbone structure is represented as Nres independent rotations \nand translations, each with respect to the global frame (residue gas) \n(Fig. 3e). These rotations and translations—representing the geometry \nof the N-Cα-C atoms—prioritize the orientation of the protein back-\nbone so that the location of the side chain of each residue is highly \nconstrained within that frame. Conversely, the peptide bond geometry \nis completely unconstrained and the network is observed to frequently \nviolate the chain constraint during the application of the structure mod-\nule as breaking this constraint enables the local refinement of all parts \nof the chain without solving complex loop closure problems. Satisfac-\ntion of the peptide bond geometry is encouraged during fine-tuning \nby a violation loss term. Exact enforcement of peptide bond geometry \nis only achieved in the post-prediction relaxation of the structure by \ngradient descent in the Amber32 force field.

First, a geometry-aware attention operation that we term \n‘invariant point attention’ (IPA) is used to update an Nres set of neural \nactivations (single representation) without changing the 3D positions, \nthen an equivariant update operation is performed on the residue gas \nusing the updated activations. The IPA augments each of the usual \nattention queries, keys and values with 3D points that are produced \nin the local frame of each residue such that the final value is invariant \nto global rotations and translations (see Methods ‘IPA’ for details). The \n3D queries and keys also impose a strong spatial/locality bias on the \nattention, which is well-suited to the iterative refinement of the protein \nstructure. After each attention operation and element-wise transition \nblock, the module computes an update to the rotation and translation \nof each backbone frame. The application of these updates within the \nlocal frame of each residue makes the overall attention and update \nblock an equivariant operation on the residue gas.\nPredictions of side-chain χ angles as well as the final, per-residue \naccuracy of the structure (pLDDT) are computed with small per-residue \nnetworks on the final activations at the end of the network. The estimate \nof the TM-score (pTM) is obtained from a pairwise error prediction that \nis computed as a linear projection from the final pair representation. The \nfinal loss (which we term the frame-aligned point error (FAPE) (Fig. 3f)) \ncompares the predicted atom positions to the true positions under \nmany different alignments. For each alignment, defined by aligning \nthe predicted frame (Rk, tk) to the corresponding true frame, we com-\npute the distance of all predicted atom positions xi from the true atom \npositions. The resulting Nframes × Natoms distances are penalized with a \nclamped L1 loss. This creates a strong bias for atoms to be correct relative \nto the local frame of each residue and hence correct with respect to its \nside-chain interactions, as well as providing the main source of chirality \nfor AlphaFold (Supplementary Methods 1.9.3 and Supplementary Fig. 9).\nTraining with labelled and unlabelled data\nThe AlphaFold architecture is able to train to high accuracy using only \nsupervised learning on PDB data, but we are able to enhance accuracy \n(Fig. 4a) using an approach similar to noisy student self-distillation35. \nIn this procedure, we use a trained network to predict the structure of \naround 350,000 diverse sequences from Uniclust3036 and make a new \ndataset of predicted structures filtered to a high-confidence subset. We \nthen train the same architecture again from scratch using a mixture of \nPDB data and this new dataset of predicted structures as the training \ndata, in which the various training data augmentations such as crop-\nping and MSA subsampling make it challenging for the network to \nrecapitulate the previously predicted structures. This self-distillation \nprocedure makes effective use of the unlabelled sequence data and \nconsiderably improves the accuracy of the resulting network.\nAdditionally, we randomly mask out or mutate individual residues \nwithin the MSA and have a Bidirectional Encoder Representations from \nTransformers (BERT)-style37 objective to predict the masked elements of \nthe MSA sequences. This objective encourages the network to learn to \ninterpret phylogenetic and covariation relationships without hardcoding \na particular correlation statistic into the features. The BERT objective is \ntrained jointly with the normal PDB structure loss on the same training \nexamples and is not pre-trained, in contrast to recent independent work38.\nInterpreting the neural network\nTo understand how AlphaFold predicts protein structure, we trained \na separate structure module for each of the 48 Evoformer blocks in \nthe network while keeping all parameters of the main network fro-\nzen (Supplementary Methods 1.14). Including our recycling stages, \nthis provides a trajectory of 192 intermediate structures—one per full \nEvoformer block—in which each intermediate represents the belief of \nthe network of the most likely structure at that block. The resulting \ntrajectories are surprisingly smooth after the first few blocks, show-\ning that AlphaFold makes constant incremental improvements to the \nstructure until it can no longer improve (see Fig. 4b for a trajectory of \naccuracy). These trajectories also illustrate the role of network depth. \nFor very challenging proteins such as ORF8 of SARS-CoV-2 (T1064), \nthe network searches and rearranges secondary structure elements \nfor many layers before settling on a good structure. For other proteins \nsuch as LmrP (T1024), the network finds the final structure within the \nfirst few layers. Structure trajectories of CASP14 targets T1024, T1044, \nT1064 and T1091 that demonstrate a clear iterative building process \nfor a range of protein sizes and difficulties are shown in Supplementary \nVideos 1–4. In Supplementary Methods 1.16 and Supplementary Figs. 12, \n13, we interpret the attention maps produced by AlphaFold layers.\nFigure 4a contains detailed ablations of the components of AlphaFold \nthat demonstrate that a variety of different mechanisms contribute \nto AlphaFold accuracy.

The model uses MSAs \nand the accuracy decreases substantially when the median alignment \ndepth is less than around 30 sequences (see Fig. 5a for details). We \nobserve a threshold effect where improvements in MSA depth over \naround 100 sequences lead to small gains. We hypothesize that the MSA \ninformation is needed to coarsely find the correct structure within the \nearly stages of the network, but refinement of that prediction into a \nhigh-accuracy model does not depend crucially on the MSA information. \nThe other substantial limitation that we have observed is that AlphaFold \nis much weaker for proteins that have few intra-chain or homotypic con-\ntacts compared to the number of heterotypic contacts (further details \nare provided in a companion paper39). This typically occurs for bridging \ndomains within larger complexes in which the shape of the protein is \ncreated almost entirely by interactions with other chains in the complex. \nConversely, AlphaFold is often able to give high-accuracy predictions for \nhomomers, even when the chains are substantially intertwined (Fig. 5b). \nWe expect that the ideas of AlphaFold are readily applicable to predicting \nfull hetero-complexes in a future system and that this will remove the dif-\nficulty with protein chains that have a large number of hetero-contacts.\nRelated work\nThe prediction of protein structures has had a long and varied develop-\nment, which is extensively covered in a number of reviews14,40–43. Despite \nthe long history of applying neural networks to structure prediction14,42,43, \nthey have only recently come to improve structure prediction10,11,44,45. \nThese approaches effectively leverage the rapid improvement in com-\nputer vision systems46 by treating the problem of protein structure \nprediction as converting an ‘image’ of evolutionary couplings22–24 to an \n‘image’ of the protein distance matrix and then integrating the distance \npredictions into a heuristic system that produces the final 3D coordinate \nprediction. A few recent studies have been developed to predict the 3D \ncoordinates directly47–50, but the accuracy of these approaches does not \nmatch traditional, hand-crafted structure prediction pipelines51. In paral-\nlel, the success of attention-based networks for language processing52 \nand, more recently, computer vision31,53 has inspired the exploration of \nattention-based methods for interpreting protein sequences54–56.\nDiscussion\nThe methodology that we have taken in designing AlphaFold is a combi-\nnation of the bioinformatics and physical approaches: we use a physical \nand geometric inductive bias to build components that learn from PDB \ndata with minimal imposition of handcrafted features (for example, \nAlphaFold builds hydrogen bonds effectively without a hydrogen bond \nscore function). This results in a network that learns far more efficiently \nfrom the limited data in the PDB but is able to cope with the complexity \nand variety of structural data.\nIn particular, AlphaFold is able to handle missing the physical context \nand produce accurate models in challenging cases such as intertwined \nhomomers or proteins that only fold in the presence of an unknown \nhaem group. The ability to handle underspecified structural conditions \nis essential to learning from PDB structures as the PDB represents the \nfull range of conditions in which structures have been solved. In gen-\neral, AlphaFold is trained to produce the protein structure most likely \nto appear as part of a PDB structure. For example, in cases in which a \nparticular stochiometry, ligand or ion is predictable from the sequence \nalone, AlphaFold is likely to produce a structure that respects those \nconstraints implicitly.\nAlphaFold has already demonstrated its utility to the experimental \ncommunity, both for molecular replacement57 and for interpreting \ncryogenic electron microscopy maps58. Moreover, because AlphaFold \noutputs protein coordinates directly, AlphaFold produces predictions \nin graphics processing unit (GPU) minutes to GPU hours depending on \nthe length of the protein sequence (for example, around one GPU min-\nute per model for 384 residues; see Methods for details). This opens up \nthe exciting possibility of predicting structures at the proteome-scale \nand beyond—in a companion paper39, we demonstrate the application \nof AlphaFold to the entire human proteome39.\nThe explosion in available genomic sequencing techniques and data \nhas revolutionized bioinformatics but the intrinsic challenge of experi-\nmental structure determination has prevented a similar expansion in \nour structural knowledge.

Each of these representations \ncontributes affinities to the shared attention weights and then uses \nthese weights to map its values to the output. The IPA operates in 3D \nspace. Each residue produces query points, key points and value points \nin its local frame. These points are projected into the global frame using \nthe backbone frame of the residue in which they interact with each \nother. The resulting points are then projected back into the local frame. \nThe affinity computation in the 3D space uses squared distances and \nthe coordinate transformations ensure the invariance of this module \nwith respect to the global frame (see Supplementary Methods 1.8.2 \n‘Invariant point attention (IPA)’ for the algorithm, proof of invariance \nand a description of the full multi-head version). A related construc-\ntion that uses classic geometric invariants to construct pairwise fea-\ntures in place of the learned 3D points has been applied to protein \ndesign59.\nIn addition to the IPA, standard dot product attention is computed \non the abstract single representation and a special attention on the pair \nrepresentation. The pair representation augments both the logits and \nthe values of the attention process, which is the primary way in which \nthe pair representation controls the structure generation.\nInputs and data sources\nInputs to the network are the primary sequence, sequences from evo-\nlutionarily related proteins in the form of a MSA created by standard \ntools including jackhmmer60 and HHBlits61, and 3D atom coordinates \nof a small number of homologous structures (templates) where avail-\nable. For both the MSA and templates, the search processes are tuned \nfor high recall; spurious matches will probably appear in the raw MSA \nbut this matches the training condition of the network.\nOne of the sequence databases used, Big Fantastic Database (BFD), \nwas custom-made and released publicly (see ‘Data availability’) and \nwas used by several CASP teams. BFD is one of the largest publicly avail-\nable collections of protein families. It consists of 65,983,866 families \nrepresented as MSAs and hidden Markov models (HMMs) covering \n2,204,359,010 protein sequences from reference databases, metage-\nnomes and metatranscriptomes.\nBFD was built in three steps. First, 2,423,213,294 protein sequences \nwere collected from UniProt (Swiss-Prot&TrEMBL, 2017-11)62, a soil refer-\nence protein catalogue and the marine eukaryotic reference catalogue7, \nand clustered to 30% sequence identity, while enforcing a 90% align-\nment coverage of the shorter sequences using MMseqs2/Linclust63. \nThis resulted in 345,159,030 clusters. For computational efficiency, \nwe removed all clusters with less than three members, resulting in \n61,083,719 clusters. Second, we added 166,510,624 representative pro-\ntein sequences from Metaclust NR (2017-05; discarding all sequences \nshorter than 150 residues)63 by aligning them against the cluster rep-\nresentatives using MMseqs264. Sequences that fulfilled the sequence \nidentity and coverage criteria were assigned to the best scoring cluster. \nThe remaining 25,347,429 sequences that could not be assigned were \nclustered separately and added as new clusters, resulting in the final \nclustering. Third, for each of the clusters, we computed an MSA using \nFAMSA65 and computed the HMMs following the Uniclust HH-suite \ndatabase protocol36.\nThe following versions of public datasets were used in this study. Our \nmodels were trained on a copy of the PDB5 downloaded on 28 August \n2019. For finding template structures at prediction time, we used a copy \nof the PDB downloaded on 14 May 2020, and the PDB7066 clustering \ndatabase downloaded on 13 May 2020. For MSA lookup at both training \nand prediction time, we used Uniref9067 v.2020_01, BFD, Uniclust3036 \nv.2018_08 and MGnify6 v.2018_12. For sequence distillation, we used \nUniclust3036 v.2018_08 to construct a distillation structure dataset. \nFull details are provided in Supplementary Methods 1.2.\nFor MSA search on BFD + Uniclust30, and template search against \nPDB70, we used HHBlits61 and HHSearch66 from hh-suite v.3.0-beta.3 \n(version 14/07/2017). For MSA search on Uniref90 and clustered MGnify, \nwe used jackhmmer from HMMER368. For constrained relaxation of \nstructures, we used OpenMM v.7.3.169 with the Amber99sb force field32. \nFor neural network construction, running and other analyses, we used \nTensorFlow70, Sonnet71, NumPy72, Python73 and Colab74.\nTo quantify the effect of the different sequence data sources, we \nre-ran the CASP14 proteins using the same models but varying how the \nMSA was constructed. Removing BFD reduced the mean accuracy by \n0.4 GDT, removing Mgnify reduced the mean accuracy by 0.7 GDT, and \nremoving both reduced the mean accuracy by 6.1 GDT. In each case, we \nfound that most targets had very small changes in accuracy but a few \noutliers had very large (20+ GDT) differences. This is consistent with the \nresults in Fig. 5a in which the depth of the MSA is relatively unimportant \nuntil it approaches a threshold value of around 30 sequences when the \nMSA size effects become quite large. We observe mostly overlapping \neffects between inclusion of BFD and Mgnify, but having at least one \nof these metagenomics databases is very important for target classes \nthat are poorly represented in UniRef, and having both was necessary \nto achieve full CASP accuracy.\nTraining regimen\nTo train, we use structures from the PDB with a maximum release date \nof 30 April 2018. Chains are sampled in inverse proportion to cluster \nsize of a 40% sequence identity clustering. We then randomly crop \nthem to 256 residues and assemble into batches of size 128. We train the \nmodel on Tensor Processing Unit (TPU) v3 with a batch size of 1 per TPU \ncore, hence the model uses 128 TPU v3 cores. The model is trained until \nconvergence (around 10 million samples) and further fine-tuned using \nlonger crops of 384 residues, larger MSA stack and reduced learning \nrate (see Supplementary Methods 1.11 for the exact configuration). The \ninitial training stage takes approximately 1 week, and the fine-tuning \nstage takes approximately 4 additional days.\nThe network is supervised by the FAPE loss and a number of auxil-\niary losses. First, the final pair representation is linearly projected to \na binned distance distribution (distogram) prediction, scored with \na cross-entropy loss. Second, we use random masking on the input \nMSAs and require the network to reconstruct the masked regions \nfrom the output MSA representation using a BERT-like loss37. Third, \nthe output single representations of the structure module are used to \npredict binned per-residue lDDT-Cα values. Finally, we use an auxiliary \nside-chain loss during training, and an auxiliary structure violation loss \nduring fine-tuning. Detailed descriptions and weighting are provided \nin the Supplementary Information.\nAn initial model trained with the above objectives was used to make \nstructure predictions for a Uniclust dataset of 355,993 sequences with \nthe full MSAs. These predictions were then used to train a final model \nwith identical hyperparameters, except for sampling examples 75% of \nthe time from the Uniclust prediction set, with sub-sampled MSAs, and \n25% of the time from the clustered PDB set.\nWe train five different models using different random seeds, some \nwith templates and some without, to encourage diversity in the predic-\ntions (see Supplementary Table 5 and Supplementary Methods 1.12.1 \nfor details). We also fine-tuned these models after CASP14 to add a \npTM prediction objective (Supplementary Methods 1.9.7) and use the \nobtained models for Fig. 2d.\nInference regimen\nWe inference the five trained models and use the predicted confidence \nscore to select the best model per target.\nUsing our CASP14 configuration for AlphaFold, the trunk of the net-\nwork is run multiple times with different random choices for the MSA \ncluster centres (see Supplementary Methods 1.11.2 for details of the \nensembling procedure). The full time to make a structure prediction \nvaries considerably depending on the length of the protein. Repre-\nsentative timings for the neural network using a single model on V100 \nGPU are 4.8 min with 256 residues, 9.2 min with 384 residues and 18 h \nat 2,500 residues. These timings are measured using our open-source \ncode, and the open-source code is notably faster than the version we \nran in CASP14 as we now use the XLA compiler75.\nSince CASP14, we have found that the accuracy of the network with-\nout ensembling is very close or equal to the accuracy with ensembling \nand we turn off ensembling for most inference. Without ensembling, \nthe network is 8× faster and the representative timings for a single \nmodel are 0.6 min with 256 residues, 1.1 min with 384 residues and \n2.1 h with 2,500 residues.\nInferencing large proteins can easily exceed the memory of a single \nGPU. For a V100 with 16 GB of memory, we can predict the structure \nof proteins up to around 1,300 residues without ensembling and the \n256- and 384-residue inference times are using the memory of a single \nGPU. The memory usage is approximately quadratic in the number of \nresidues, so a 2,500-residue protein involves using unified memory so \nthat we can greatly exceed the memory of a single V100. In our cloud \nsetup, a single V100 is used for computation on a 2,500-residue protein \nbut we requested four GPUs to have sufficient memory.\nSearching genetic sequence databases to prepare inputs and final \nrelaxation of the structures take additional central processing unit \n(CPU) time but do not require a GPU or TPU.\nMetrics\nThe predicted structure is compared to the true structure from the \nPDB in terms of lDDT metric34, as this metric reports the domain accu-\nracy without requiring a domain segmentation of chain structures. \nThe distances are either computed between all heavy atoms (lDDT) \nor only the Cα atoms to measure the backbone accuracy (lDDT-Cα). \nAs lDDT-Cα only focuses on the Cα atoms, it does not include the pen-\nalty for structural violations and clashes. Domain accuracies in CASP \nare reported as GDT33 and the TM-score27 is used as a full chain global \nsuperposition metric.\nWe also report accuracies using the r.m.s.d.95 (Cα r.m.s.d. at 95% cov-\nerage). We perform five iterations of (1) a least-squares alignment of the \npredicted structure and the PDB structure on the currently chosen Cα \natoms (using all Cα atoms in the first iteration); (2) selecting the 95% \nof Cα atoms with the lowest alignment error. The r.m.s.d. of the atoms \nchosen for the final iterations is the r.m.s.d.95. This metric is more robust \nto apparent errors that can originate from crystal structure artefacts, \nalthough in some cases the removed 5% of residues will contain genuine \nmodelling errors.\nTest set of recent PDB sequences\nFor evaluation on recent PDB sequences (Figs. 2a–d, 4a, 5a), we used \na copy of the PDB downloaded 15 February 2021. Structures were fil-\ntered to those with a release date after 30 April 2018 (the date limit for \ninclusion in the training set for AlphaFold). Chains were further filtered \nto remove sequences that consisted of a single amino acid as well as \nsequences with an ambiguous chemical component at any residue \nposition. Exact duplicates were removed, with the chain with the most \nresolved Cα atoms used as the representative sequence. Subsequently, \nstructures with less than 16 resolved residues, with unknown residues \nor solved by NMR methods were removed. As the PDB contains many \nnear-duplicate sequences, the chain with the highest resolution was \nselected from each cluster in the PDB 40% sequence clustering of the \ndata. Furthermore, we removed all sequences for which fewer than \n80 amino acids had the alpha carbon resolved and removed chains with \nmore than 1,400 residues. The final dataset contained 10,795 protein \nsequences.\nThe procedure for filtering the recent PDB dataset based on prior \ntemplate identity was as follows. Hmmsearch was run with default \nparameters against a copy of the PDB SEQRES fasta downloaded \n15 February 2021. Template hits were accepted if the associated struc-\nture had a release date earlier than 30 April 2018. Each residue position \nin a query sequence was assigned the maximum identity of any template \nhit covering that position. Filtering then proceeded as described in \nthe individual figure legends, based on a combination of maximum \nidentity and sequence coverage.\nThe MSA depth analysis was based on computing the normalized \nnumber of effective sequences (Neff) for each position of a query \nsequence. Per-residue Neff values were obtained by counting the num-\nber of non-gap residues in the MSA for this position and weighting the \nsequences using the Neff scheme76 with a threshold of 80% sequence \nidentity measured on the region that is non-gap in either sequence.\nReporting summary\nFurther information on research design is available in the Nature \nResearch Reporting Summary linked to this paper.\nData availability\nAll input data are freely available from public sources.\nStructures from the PDB were used for training and as templates \n(https://www.wwpdb.org/ftp/pdb-ftp-sites; for the associated \nsequence data and 40% sequence clustering see also https://ftp.wwpdb.\norg/pub/pdb/derived_data/ and https://cdn.rcsb.org/resources/\nsequence/clusters/bc-40.out).

Briefly this excludes chains with too few resolved residues, longer than 1400 \nresidues, solved by NMR or with unknown/ambiguous residues. This set was also redundancy reduced (by taking representatives from a \nsequence clustering), and for some figures a sequence similarity-based filter was applied to remove entries too similar to the training set (see \nMethods and figure legends for details).\nReplication\nNot applicable, no experimental work is described in this study.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Our model achieves 28.4 BLEU on the WMT 2014 English-\nto-German translation task, improving over the existing best results, including\nensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task,\nour model establishes a new single-model state-of-the-art BLEU score of 41.8 after\ntraining for 3.5 days on eight GPUs, a small fraction of the training costs of the\nbest models from the literature.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Our model achieves 28.4 BLEU on the WMT 2014 English-\nto-German translation task, improving over the existing best results, including\nensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task,\nour model establishes a new single-model state-of-the-art BLEU score of 41.8 after\ntraining for 3.5 days on eight GPUs, a small fraction of the training costs of the\nbest models from the literature.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Today we're diving into the fascinating world of AI with a focus on the Transformer model, a groundbreaking architecture that's revolutionizing sequence transduction tasks.\n\nHOST 1: Let's start with the basics, Jamie. What exactly is the Transformer model, and why is it such a big deal?\nHOST 2: The Transformer model is a novel sequence transduction architecture that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift addresses some of the key limitations of RNNs, particularly their difficulty in parallelizing computation, which can be a bottleneck in processing large datasets.\n\nHOST 1: It sounds like attention mechanisms are central to this model. Can you give us some background on how they work?\nHOST 2: Absolutely. Attention mechanisms have been used in neural networks for a while, especially in tasks like machine translation. They allow the model to focus on specific parts of the input sequence, which is crucial for understanding context. The Transformer takes this a step further by using self-attention, which enables the model to weigh the importance of different words in a sentence relative to each other, all at once.\n\nHOST 1: Let's get into the nuts and bolts of the Transformer. What makes its architecture unique?\nHOST 2: The Transformer is built around an encoder-decoder structure, but what sets it apart is the use of multi-head attention and position-wise feed-forward networks. Multi-head attention allows the model to attend to information from different representation subspaces simultaneously, which enhances its ability to capture complex patterns. The position-wise feed-forward networks help the model learn long-range dependencies, which is crucial for understanding context over longer sequences.\n\nHOST 1: You mentioned self-attention earlier.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting.

This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

And what about the training process? How do they ensure the model performs well?\n\n**Alex:** The training regime for the Transformer model includes techniques like batch normalization, dropout, and label smoothing. These help improve the model's stability and performance. They also use a warm-up schedule and learning rate schedules to optimize the training process.\n\n**Jamie:** It sounds like a lot of thought went into making this model robust. What about the results? How does the Transformer model perform compared to traditional RNNs?\n\n**Alex:** The results are impressive. The Transformer model achieved significant improvements in BLEU scores on machine translation tasks, specifically on the WMT 2014 English-to-German and English-to-French datasets. These improvements set new state-of-the-art results, demonstrating the model's superior performance.\n\n**Jamie:** That's incredible! So, what are the broader implications of this research? How might it impact the field of machine learning?\n\n**Alex:** The introduction of the Transformer model has opened up new possibilities for sequence transduction tasks. Its ability to efficiently handle long sequences and learn complex dependencies makes it a valuable tool for a wide range of applications, from natural language processing to computer vision.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm Alex, your host, and today we're exploring a groundbreaking development in the field of machine learning: the Transformer model.\n\n**Host 2 (Jamie):** And I'm Jamie. I'm excited to discuss this with you, Alex. The Transformer model has really shaken up the world of AI, especially in how we handle sequence transduction tasks. Let's start with the basics. What exactly is the Transformer model?\n\n**Alex:** Great question, Jamie. The Transformer model is a novel architecture introduced to address the limitations of traditional recurrent neural networks, or RNNs. Instead of relying on recurrence, the Transformer uses self-attention mechanisms to process sequences.\n\n**Jamie:** So, why move away from RNNs? What are the limitations that the Transformer addresses?\n\n**Alex:** RNNs have been the go-to for sequence tasks, but they struggle with parallelization and can be computationally expensive. The Transformer, with its self-attention mechanism, allows for more efficient computation and scalability. This is a game-changer for tasks like machine translation.\n\n**Jamie:** That sounds promising. Can you explain how self-attention works in the Transformer?\n\n**Alex:** Absolutely. Self-attention allows the model to weigh the importance of different words in a sequence, regardless of their position. This is achieved through a mechanism called scaled dot-product attention, which efficiently computes attention weights using matrix multiplication.\n\n**Jamie:** And I understand there's something called multi-head attention involved. What's that about?\n\n**Alex:** Multi-head attention is one of the key innovations of the Transformer. It allows the model to attend to information from different representation subspaces simultaneously. This means the model can capture various aspects of the input data at once, improving its ability to understand complex sequences.\n\n**Jamie:** Fascinating. It sounds like the Transformer is quite sophisticated. How does it handle long-range dependencies, which are often a challenge for RNNs?\n\n**Alex:** The Transformer uses position-wise feed-forward networks and learned embeddings to capture long-range dependencies effectively. These components help the model maintain context over longer sequences, which is crucial for tasks like translation.\n\n**Jamie:** Speaking of translation, I heard the Transformer has achieved impressive results in this area. Can you tell us more about that?\n\n**Alex:** Yes, the results are indeed impressive. The Transformer has set new benchmarks in machine translation tasks, such as the WMT 2014 English-to-German and English-to-French translations. It significantly outperforms traditional RNN-based models in terms of BLEU scores, which measure translation quality.\n\n**Jamie:** That's a huge achievement. What about other tasks? Has the Transformer been tested beyond translation?\n\n**Alex:** Definitely. The Transformer has also shown remarkable improvements in English constituency parsing tasks, achieving higher F1 scores compared to RNNs. This demonstrates its versatility and potential for other sequence transduction tasks.\n\n**Jamie:** It's clear that the Transformer is a powerful model. But what about training? Are there any specific techniques used to optimize its performance?\n\n**Alex:** Training the Transformer involves several techniques, such as batch normalization, dropout, and label smoothing. These help stabilize the training process and improve the model's generalization. Additionally, a warm-up schedule and learning rate adjustments are crucial for achieving optimal performance.\n\n**Jamie:** It sounds like a lot of thought went into designing and training this model. What do you think are the broader implications of the Transformer's success?\n\n**Alex:** The success of the Transformer opens up new possibilities for AI applications. Its efficiency and scalability make it suitable for a wide range of tasks beyond translation and parsing. We're likely to see self-attention mechanisms being applied to other areas, such as speech recognition and image processing.\n\n**Jamie:** That's exciting to hear. As we wrap up, what do you think is the future of self-attention mechanisms in AI?\n\n**Alex:** The future looks promising. As researchers continue to explore and refine these mechanisms, we can expect even more innovative applications and improvements in AI performance.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm Alex, your host, and today we're exploring a game-changing development in the world of AI: the Transformer model.\n\n**Host 2 (Jamie):** And I'm Jamie. I'm excited to be here, Alex. The Transformer model has been making waves in the AI community, especially in the realm of natural language processing. Let's start with the basics. What exactly is the Transformer model?\n\n**Alex:** Great question, Jamie. The Transformer model is a new sequence transduction architecture introduced to address some of the limitations of traditional recurrent neural networks, or RNNs. Instead of relying on RNNs, the Transformer uses self-attention mechanisms, which allow for more efficient and scalable processing of sequences.\n\n**Jamie:** So, it's all about improving efficiency and scalability. How does self-attention differ from what RNNs do?\n\n**Alex:** RNNs process sequences one step at a time, which can be computationally intensive and difficult to parallelize. Self-attention, on the other hand, allows the model to consider all positions in the sequence simultaneously. This not only speeds up computation but also helps the model learn long-range dependencies more effectively.\n\n**Jamie:** That sounds like a significant improvement. The paper also mentions the model's architecture. Can you break that down for us?\n\n**Alex:** Absolutely. The Transformer model consists of an encoder and a decoder, both of which use multi-head attention and position-wise feed-forward networks. Multi-head attention is particularly interesting because it allows the model to attend to information from different representation subspaces at different positions.\n\n**Jamie:** Multi-head attention sounds complex. Why is it so important?\n\n**Alex:** It's crucial because it enables the model to capture different aspects of the input data simultaneously. This means the model can understand context better and make more accurate predictions. The architecture also includes residual connections and layer normalization, which improve stability and performance.\n\n**Jamie:** Fascinating. Now, let's talk about training. What techniques are used to train the Transformer model?\n\n**Alex:** The training regime includes batch normalization, dropout, and label smoothing. These techniques help prevent overfitting and improve the model's generalization capabilities. The authors also emphasize the importance of using a warm-up schedule and learning rate schedules to enhance stability and performance.\n\n**Jamie:** It sounds like a lot of thought went into optimizing the training process. What about the results? How does the Transformer model perform compared to traditional RNNs?\n\n**Alex:** The results are impressive. The Transformer model achieved significant improvements in BLEU scores on machine translation tasks, such as WMT 2014 English-to-German and English-to-French. These improvements set new state-of-the-art results, demonstrating the model's superior performance.\n\n**Jamie:** That's incredible. What do these improvements mean for real-world applications?\n\n**Alex:** Higher BLEU scores indicate better translation quality, which can have a huge impact on industries relying on machine translation, like global communication and content localization. The model's efficiency also means faster processing times, which is crucial for real-time applications.\n\n**Jamie:** It's exciting to think about the potential applications. Are there any other areas where self-attention mechanisms could be applied?\n\n**Alex:** Definitely. While the paper focuses on machine translation, self-attention mechanisms have potential in other sequence transduction tasks, such as speech recognition and text summarization. The flexibility and efficiency of self-attention make it a promising tool for various AI applications.\n\n**Jamie:** It sounds like the Transformer model is just the beginning of a new era in AI. Any final thoughts, Alex?\n\n**Alex:** The introduction of the Transformer model marks a significant shift in how we approach sequence transduction tasks.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

So, Alex, what exactly is the Transformer model, and why is it so important?\n\n**Alex:** Great question, Jamie. The Transformer model is a new sequence transduction architecture introduced to address some of the limitations of traditional recurrent neural networks, or RNNs.

This makes it much more efficient and scalable.\n\n**Jamie:** That sounds like a significant improvement. Can you explain what self-attention is and how it differs from what RNNs do?\n\n**Alex:** Absolutely. In traditional RNNs, each element in a sequence is processed one at a time, which can be slow and computationally expensive. Self-attention, on the other hand, allows the model to weigh the importance of different elements in a sequence simultaneously. This means the model can focus on the most relevant parts of the input data, regardless of their position in the sequence.\n\n**Jamie:** So, it's like being able to read a book by focusing on the key sentences all at once, rather than reading line by line?\n\n**Alex:** Exactly!

This allows the model to attend to information from different representation subspaces at different positions, improving its ability to learn complex patterns.\n\n**Jamie:** That's fascinating. How does this translate into real-world applications?\n\n**Alex:** One of the most notable applications is in machine translation. The Transformer model has achieved significant improvements in BLEU scores, which are a measure of translation quality, on tasks like English-to-German and English-to-French translation. It's set new state-of-the-art results, outperforming traditional RNN-based architectures.\n\n**Jamie:** Impressive! It sounds like the Transformer model is a big deal for natural language processing. What about its training process? Are there any unique aspects there?\n\n**Alex:** Yes, the training process is quite sophisticated.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Experiments on two machine translation tasks show these models to\nbe superior in quality while being more parallelizable and requiring significantly\nless time to train. Our model achieves 28.4 BLEU on the WMT 2014 English-\nto-German translation task, improving over the existing best results, including\nensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task,\nour model establishes a new single-model state-of-the-art BLEU score of 41.8 after\ntraining for 3.5 days on eight GPUs, a small fraction of the training costs of the\nbest models from the literature. We show that the Transformer generalizes well to\nother tasks by applying it successfully to English constituency parsing both with\nlarge and limited training data.\n∗Equal contribution.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Today we're diving into a fascinating topic that's been making waves in the AI community: the Transformer model. This model is revolutionizing how we approach sequence transduction tasks.\n\nHOST 1: Absolutely. Let's start with the Introduction. The paper introduces the Transformer model as a new sequence transduction architecture that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This is a big deal because it addresses some of the limitations of RNNs, particularly in terms of parallelization and computational efficiency.\n\nHOST 2: Right. And in the Background section, the authors provide context on attention mechanisms in neural networks. They discuss how these mechanisms have been used in tasks like machine translation and highlight the potential benefits of self-attention, such as improved parallelization and reduced computational complexity.\n\nHOST 1: Moving on to the Model Architecture, this section is quite detailed. The Transformer model consists of an encoder and a decoder, both utilizing multi-head attention and position-wise feed-forward networks. Multi-head attention is particularly interesting because it allows the model to attend to information from different representation subspaces at different positions.\n\nHOST 2: And there's also the concept of scaled dot-product attention, which is crucial for efficient computation of attention weights. By scaling the dot products, the model improves stability and performance, especially with large input sequences.\n\nHOST 1: Exactly. The Why Self-Attention section compares self-attention mechanisms with traditional RNN-based architectures, highlighting their advantages in terms of computational complexity and ability to learn long-range dependencies.\n\nHOST 2: In the Training section, the authors describe techniques like batch normalization, dropout, and label smoothing. They also emphasize the importance of using a warm-up schedule and learning rate schedules to stabilize training.\n\nHOST 1: The Results section is where we see the impact of these innovations. The Transformer model achieved significant improvements in BLEU scores for machine translation tasks, setting new state-of-the-art results for English-to-German and English-to-French translations.\n\nHOST 2: That's impressive. And the Conclusion wraps up by summarizing the key contributions and results, emphasizing the potential applications of self-attention mechanisms in other sequence transduction tasks.\n\nHOST 1: It's clear that the Transformer model is a game-changer in the field of AI. Its success in machine translation is just the beginning, and there's a lot of potential for further research and application.\n\nHOST 2: Thanks for breaking it down for us.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm [Host 1 Name], your resident tech expert.\n\n**Host 2 (Curious Enthusiast):** And I'm [Host 2 Name], here to ask the questions you're all thinking about. Today, we're exploring a groundbreaking paper that introduced the Transformer model, a game-changer in the world of AI. So, [Host 1], what exactly is the Transformer model, and why is it so important?\n\n**Host 1:** Great question! The Transformer model is a novel sequence transduction architecture that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift addresses some of the key limitations of RNNs, such as their difficulty in parallelizing computation.\n\n**Host 2:** So, it's all about making things faster and more efficient?\n\n**Host 1:** Exactly. The self-attention mechanism allows the Transformer to process sequences in parallel, which significantly speeds up computation and makes the model more scalable. This is particularly important for tasks like machine translation, where you need to handle large amounts of data quickly.\n\n**Host 2:** That sounds impressive. But how does the Transformer actually work? What makes its architecture so special?\n\n**Host 1:** The Transformer is built around two main components: the encoder and the decoder. Both use multi-head attention and position-wise feed-forward networks. Multi-head attention is a key innovation here—it allows the model to attend to different parts of the input sequence simultaneously, capturing various aspects of the data.\n\n**Host 2:** And what about those position-wise feed-forward networks? How do they fit into the picture?\n\n**Host 1:** They help the model learn long-range dependencies by applying fully connected layers to each position in the sequence independently. This enhances the model's ability to understand complex patterns in the data.\n\n**Host 2:** It sounds like the Transformer is packed with innovations. But why is self-attention such a big deal compared to traditional RNNs?\n\n**Host 1:** Self-attention offers several advantages. It's more computationally efficient, allows for better parallelization, and can capture long-range dependencies more effectively. This makes it a powerful tool for sequence-to-sequence tasks.\n\n**Host 2:** Let's talk about the results. How did the Transformer perform in experiments?\n\n**Host 1:** The results were remarkable. In machine translation tasks, the Transformer achieved significant improvements in BLEU scores, setting new state-of-the-art results for English-to-German and English-to-French translations. It also excelled in English constituency parsing tasks, achieving higher F1 scores than traditional RNN-based models.\n\n**Host 2:** That's incredible! What do these results mean for the future of AI?\n\n**Host 1:** The success of the Transformer model has opened up new possibilities for AI applications.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture. Unlisted values are identical to those of the base\nmodel. All metrics are on the English-to-German translation development set, newstest2013.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm Alex, your host for today's episode.\n\n**Host 2 (Jamie):** And I'm Jamie. Today, we're going to discuss a groundbreaking development in the field of machine learning—the Transformer model. It's a topic that's been making waves in the tech community, and we're excited to break it down for you.\n\n**Alex:** That's right, Jamie. The Transformer model is a new sequence transduction architecture that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. It's a big deal because it addresses some of the limitations of RNNs, particularly when it comes to parallelizing computation.\n\n**Jamie:** So, Alex, what exactly are these limitations, and how does the Transformer model overcome them?\n\n**Alex:** Great question, Jamie. RNNs have been the go-to architecture for sequence-to-sequence tasks like machine translation. However, they process data sequentially, which makes it difficult to parallelize and can lead to inefficiencies. The Transformer model, on the other hand, uses self-attention mechanisms that allow for parallel processing, making it more efficient and scalable.\n\n**Jamie:** That sounds like a significant improvement. But what exactly is self-attention, and how does it work in the Transformer model?\n\n**Alex:** Self-attention is a mechanism that allows the model to weigh the importance of different parts of the input sequence when making predictions. In the Transformer model, this is achieved through multi-head attention, which enables the model to attend to information from different representation subspaces at different positions.\n\n**Jamie:** Multi-head attention? That sounds intriguing. Can you explain how it works?\n\n**Alex:** Absolutely. Multi-head attention involves using multiple sets of attention mechanisms, or \"heads,\" to process the input data. Each head focuses on different parts of the input, allowing the model to capture a variety of information. This is particularly useful for learning long-range dependencies in the data.\n\n**Jamie:** I see. And how does this fit into the overall architecture of the Transformer model?\n\n**Alex:** The Transformer model consists of an encoder and a decoder, each made up of stacks of layers. These layers include multi-head self-attention and position-wise feed-forward networks. The encoder processes the input sequence, while the decoder generates the output sequence, using the encoded information.\n\n**Jamie:** It sounds like a complex but powerful architecture. How does it perform compared to traditional RNN-based models?\n\n**Alex:** The results are impressive. In experiments on machine translation tasks, the Transformer model achieved significant improvements in BLEU scores, setting new state-of-the-art results for English-to-German and English-to-French translations. It's a testament to the model's efficiency and effectiveness.\n\n**Jamie:** That's incredible.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm [Host 1 Name], and today we're exploring the groundbreaking Transformer model, a game-changer in the world of sequence transduction.\n\n**Host 2 (Implications and Applications):** And I'm [Host 2 Name]. I'm excited to discuss how this model is reshaping the landscape of natural language processing and beyond. So, let's start with the basics. What exactly is the Transformer model, and why is it so important?\n\n**Host 1:** Great question! The Transformer model, introduced in the paper we're discussing today, is a new sequence transduction model that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift addresses some of the key limitations of RNNs, particularly their difficulty in parallelizing computation.\n\n**Host 2:** That's fascinating. So, how does self-attention improve upon the traditional methods?\n\n**Host 1:** Self-attention allows the model to process sequences more efficiently by enabling parallelization. It also provides the ability to jointly attend to information from different representation subspaces at different positions, which is a significant advantage over RNNs and even convolutional neural networks, or CNNs.\n\n**Host 2:** It sounds like a major leap forward. Can you walk us through the architecture of the Transformer model?\n\n**Host 1:** Absolutely. The Transformer model consists of an encoder and a decoder, both of which use multi-head attention and position-wise feed-forward networks. The encoder processes input sequences by applying self-attention to each position separately, while the decoder generates output sequences by attending to the previous layer's output.\n\n**Host 2:** And what about the attention mechanism itself? How does it work?\n\n**Host 1:** The attention mechanism in the Transformer model is based on scaled dot-product attention, which efficiently computes attention weights by scaling the dot products with a square root factor. This is combined with multi-head attention, allowing the model to attend to information from different subspaces simultaneously.\n\n**Host 2:** That's quite innovative. Now, let's talk about the training process. What techniques were used to optimize the Transformer model?\n\n**Host 1:** The authors used a combination of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. These methods help ensure the model is trained effectively on large datasets, achieving optimal performance.\n\n**Host 2:** And speaking of performance, the results were impressive, right?\n\n**Host 1:** Indeed. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including the WMT 2014 English-to-German and English-to-French translation tasks. This demonstrates the model's capability to handle complex language tasks efficiently.\n\n**Host 2:** It's clear that the Transformer model has set a new standard. What do you think are the future directions for research in this area?\n\n**Host 1:** The authors suggest exploring further improvements in attention-based models and their applications across different domains. There's also potential for enhancing the model's ability to handle even more complex tasks and larger datasets.\n\n**Host 2:** Exciting times ahead for AI research! Thank you for breaking down the technical details, [Host 1 Name]. And thank you to our listeners for joining us on this journey through the world of self-attention and the Transformer model.

It also provides the ability to jointly attend to information from different representation subspaces at different positions, which is a significant advantage over RNNs and even convolutional neural networks, or CNNs.\n\n**Host 2:** It sounds like a major leap forward. Can you walk us through the architecture of the Transformer model?\n\n**Host 1:** Absolutely. The Transformer model consists of an encoder and a decoder, both of which use multi-head attention and position-wise feed-forward networks. The encoder processes input sequences by applying self-attention to each position separately, while the decoder generates output sequences by attending to the previous layer's output.\n\n**Host 2:** And what about the attention mechanism itself? How does it work?\n\n**Host 1:** The attention mechanism in the Transformer model is based on scaled dot-product attention, which efficiently computes attention weights by scaling the dot products with a square root factor. This is combined with multi-head attention, allowing the model to attend to information from different subspaces simultaneously.\n\n**Host 2:** That's quite innovative. Now, let's talk about the training process. What techniques were used to optimize the Transformer model?\n\n**Host 1:** The authors used a combination of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. These methods help ensure the model is trained effectively on large datasets, achieving optimal performance.\n\n**Host 2:** And speaking of performance, the results were impressive, right?\n\n**Host 1:** Indeed. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including the WMT 2014 English-to-German and English-to-French translation tasks. This demonstrates the model's capability to handle complex language tasks efficiently.\n\n**Host 2:** It's clear that the Transformer model has set a new standard. What do you think are the future directions for research in this area?\n\n**Host 1:** The authors suggest exploring further improvements in attention-based models and their applications across different domains. There's also potential for enhancing the model's ability to handle even more complex tasks and larger datasets.\n\n**Host 2:** Exciting times ahead for AI research! Thank you for breaking down the technical details, [Host 1 Name]. And thank you to our listeners for joining us on this journey through the world of self-attention and the Transformer model.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Introduction**\n\nSummary: The paper introduces the Transformer model, a new sequence transduction model that replaces traditional recurrent neural networks (RNNs) with self-attention mechanisms.\n\nNotable information: The authors highlight the limitations of RNNs in parallelizing computation and argue that self-attention can provide more efficient and effective processing of sequential data.\n\n**2. Background**\n\nSummary: This section provides a background on sequence transduction models, including recurrent neural networks (RNNs), convolutional neural networks (CNNs), and attention mechanisms.\n\nNotable information: The authors discuss the limitations of RNNs in parallelizing computation and the benefits of self-attention mechanisms, which allow for more efficient processing of sequential data.\n\n**3. Model Architecture**\n\nSummary: This section describes the Transformer model architecture, including its encoder and decoder components, as well as its use of multi-head attention and position-wise feed-forward networks.\n\nNotable information: The authors introduce the concept of multi-head attention, which allows the model to jointly attend to information from different representation subspaces at different positions. They also describe the use of position-wise feed-forward networks, which provide a way to transform the output of each position separately and identically.\n\n**3.1 Encoder and Decoder Stacks**\n\nSummary: This subsection describes the architecture of the encoder and decoder stacks in the Transformer model, including their use of multi-head attention and position-wise feed-forward networks.\n\nNotable information: The authors describe how the encoder stack processes input sequences by applying self-attention to each position separately and identically. They also describe how the decoder stack generates output sequences by applying self-attention to the previous decoder layer's output.\n\n**3.2 Attention**\n\nSummary: This section describes the attention function used in the Transformer model, including its scaled dot-product attention mechanism and multi-head attention architecture.\n\nNotable information: The authors introduce the concept of scaled dot-product attention, which allows for more efficient computation of attention weights. They also describe how multi-head attention can be used to jointly attend to information from different representation subspaces at different positions.\n\n**3.2.1 Scaled Dot-Product Attention**\n\nSummary: This subsection describes the scaled dot-product attention mechanism in more detail, including its use of scaling factors and softmax functions.\n\nNotable information: The authors describe how the scaled dot-product attention mechanism allows for more efficient computation of attention weights by scaling the dot products with a square root factor. They also discuss the importance of using a softmax function to normalize the attention weights.\n\n**3.2.2 Multi-Head Attention**\n\nSummary: This subsection describes the multi-head attention architecture, including its use of linear projections and concatenated outputs.\n\nNotable information: The authors describe how multi-head attention allows for more efficient processing of sequential data by jointly attending to information from different representation subspaces at different positions. They also discuss the benefits of using multiple attention heads in parallel.\n\n**3.3 Position-wise Feed-Forward Networks**\n\nSummary: This subsection describes the position-wise feed-forward networks used in the Transformer model, including their use of linear transformations and ReLU activations.\n\nNotable information: The authors describe how position-wise feed-forward networks provide a way to transform the output of each position separately and identically. They also discuss the benefits of using these networks in conjunction with self-attention mechanisms.\n\n**3.4 Embeddings and Softmax**\n\nSummary: This section describes the embedding layers used in the Transformer model, including their use of learned embeddings and softmax functions.\n\nNotable information: The authors describe how learned embeddings can be used to convert input tokens into vectors that are more suitable for processing by self-attention mechanisms. They also discuss the importance of using a softmax function to normalize the output of these embeddings.\n\n**4. Why Self-Attention**\n\nSummary: This section compares self-attention mechanisms with traditional RNNs and CNNs, highlighting their benefits in terms of computational efficiency and parallelization.\n\nNotable information: The authors argue that self-attention mechanisms offer several advantages over traditional RNNs and CNNs, including improved computational efficiency, parallelization, and the ability to jointly attend to information from different representation subspaces at different positions.\n\n**5. Training**\n\nSummary: This section describes the training regime used for the Transformer model, including its use of batched data, Adam optimizer, and regularization techniques such as dropout and label smoothing.\n\nNotable information: The authors describe how they trained their models on large datasets using a combination of batched data, Adam optimizer, and regularization techniques.

Our model achieves 28.4 BLEU on the WMT 2014 English-\nto-German translation task, improving over the existing best results, including\nensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task,\nour model establishes a new single-model state-of-the-art BLEU score of 41.8 after\ntraining for 3.5 days on eight GPUs, a small fraction of the training costs of the\nbest models from the literature.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm [Host 1 Name], and joining me is my co-host, [Host 2 Name].\n\n**Host 2 (Industry Analyst):** Hi everyone! I'm [Host 2 Name], and today we're exploring a groundbreaking paper that introduced the Transformer model, a game-changer in the field of sequence transduction. Let's start with the basics, [Host 1]. What exactly is the Transformer model?\n\n**Host 1:** Great question! The Transformer model is a novel sequence transduction model that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift addresses some of the key limitations of RNNs, particularly their difficulty in parallelizing computation.\n\n**Host 2:** That's fascinating. So, how does the Transformer model improve upon RNNs and CNNs?\n\n**Host 1:** The main advantage lies in its use of self-attention mechanisms, which allow for more efficient and effective processing of sequential data. Unlike RNNs, which process data sequentially, the Transformer can process entire sequences in parallel, significantly speeding up computation.\n\n**Host 2:** That sounds like a huge leap forward. Can you tell us more about the model's architecture?\n\n**Host 1:** Absolutely. The Transformer model consists of an encoder and a decoder, both of which use multi-head attention and position-wise feed-forward networks. Multi-head attention allows the model to attend to information from different representation subspaces simultaneously, while position-wise feed-forward networks transform the output of each position separately.\n\n**Host 2:** And what about the training process? How do they ensure the model performs well?\n\n**Host 1:** The authors used a combination of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. They also emphasize the importance of tuning hyperparameters carefully to achieve optimal performance.\n\n**Host 2:** It sounds like a lot of work goes into training these models. What kind of results did they achieve?\n\n**Host 1:** The results were impressive. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including the WMT 2014 English-to-German and English-to-French translation tasks. It also performed well on English constituency parsing tasks, demonstrating its ability to handle long-range dependencies.\n\n**Host 2:** That's incredible. It seems like the Transformer model has a lot of potential applications. What do you think the future holds for this technology?\n\n**Host 1:** The future is bright for attention-based models. The Transformer has already inspired a wave of research and development in natural language processing and beyond. We're likely to see continued improvements in efficiency and performance, as well as new applications in areas like image processing and reinforcement learning.\n\n**Host 2:** It's an exciting time to be in the field of AI.

I'm [Host 1 Name], and joining me is my co-host, [Host 2 Name].\n\n**Host 2 (Industry Analyst):** Hi everyone! I'm [Host 2 Name], and today we're exploring a groundbreaking paper that introduced the Transformer model, a game-changer in the field of sequence transduction. Let's start with the basics, [Host 1]. What exactly is the Transformer model?\n\n**Host 1:** Great question! The Transformer model is a novel sequence transduction model that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift addresses some of the key limitations of RNNs, particularly their difficulty in parallelizing computation.\n\n**Host 2:** That's fascinating. So, how does the Transformer model improve upon RNNs and CNNs?\n\n**Host 1:** The main advantage lies in its use of self-attention mechanisms, which allow for more efficient and effective processing of sequential data. Unlike RNNs, which process data sequentially, the Transformer can process entire sequences in parallel, significantly speeding up computation.\n\n**Host 2:** That sounds like a huge leap forward. Can you tell us more about the model's architecture?\n\n**Host 1:** Absolutely. The Transformer model consists of an encoder and a decoder, both of which use multi-head attention and position-wise feed-forward networks. Multi-head attention allows the model to attend to information from different representation subspaces simultaneously, while position-wise feed-forward networks transform the output of each position separately.\n\n**Host 2:** And what about the training process? How do they ensure the model performs well?\n\n**Host 1:** The authors used a combination of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. They also emphasize the importance of tuning hyperparameters carefully to achieve optimal performance.\n\n**Host 2:** It sounds like a lot of work goes into training these models. What kind of results did they achieve?\n\n**Host 1:** The results were impressive. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including the WMT 2014 English-to-German and English-to-French translation tasks. It also performed well on English constituency parsing tasks, demonstrating its ability to handle long-range dependencies.\n\n**Host 2:** That's incredible. It seems like the Transformer model has a lot of potential applications. What do you think the future holds for this technology?\n\n**Host 1:** The future is bright for attention-based models. The Transformer has already inspired a wave of research and development in natural language processing and beyond. We're likely to see continued improvements in efficiency and performance, as well as new applications in areas like image processing and reinforcement learning.\n\n**Host 2:** It's an exciting time to be in the field of AI.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture. Unlisted values are identical to those of the base\nmodel. All metrics are on the English-to-German translation development set, newstest2013.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Introduction**\n\nSummary: The paper introduces the Transformer model, a new sequence transduction model that replaces traditional recurrent neural networks (RNNs) with self-attention mechanisms.\n\nNotable information: The authors highlight the limitations of RNNs in parallelizing computation and argue that self-attention can provide more efficient and effective processing of sequential data.\n\n**2. Background**\n\nSummary: This section provides a background on sequence transduction models, including recurrent neural networks (RNNs), convolutional neural networks (CNNs), and attention mechanisms.\n\nNotable information: The authors discuss the limitations of RNNs in parallelizing computation and the benefits of self-attention mechanisms, which allow for more efficient processing of sequential data.\n\n**3. Model Architecture**\n\nSummary: This section describes the Transformer model architecture, including its encoder and decoder components, as well as its use of multi-head attention and position-wise feed-forward networks.\n\nNotable information: The authors introduce the concept of multi-head attention, which allows the model to jointly attend to information from different representation subspaces at different positions. They also describe the use of position-wise feed-forward networks, which provide a way to transform the output of each position separately and identically.\n\n**3.1 Encoder and Decoder Stacks**\n\nSummary: This subsection describes the architecture of the encoder and decoder stacks in the Transformer model, including their use of multi-head attention and position-wise feed-forward networks.\n\nNotable information: The authors describe how the encoder stack processes input sequences by applying self-attention to each position separately and identically. They also describe how the decoder stack generates output sequences by applying self-attention to the previous decoder layer's output.\n\n**3.2 Attention**\n\nSummary: This section describes the attention function used in the Transformer model, including its scaled dot-product attention mechanism and multi-head attention architecture.\n\nNotable information: The authors introduce the concept of scaled dot-product attention, which allows for more efficient computation of attention weights. They also describe how multi-head attention can be used to jointly attend to information from different representation subspaces at different positions.\n\n**3.2.1 Scaled Dot-Product Attention**\n\nSummary: This subsection describes the scaled dot-product attention mechanism in more detail, including its use of scaling factors and softmax functions.\n\nNotable information: The authors describe how the scaled dot-product attention mechanism allows for more efficient computation of attention weights by scaling the dot products with a square root factor.

Our model achieves 28.4 BLEU on the WMT 2014 English-\nto-German translation task, improving over the existing best results, including\nensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task,\nour model establishes a new single-model state-of-the-art BLEU score of 41.8 after\ntraining for 3.5 days on eight GPUs, a small fraction of the training costs of the\nbest models from the literature. We show that the Transformer generalizes well to\nother tasks by applying it successfully to English constituency parsing both with\nlarge and limited training data.\n∗Equal contribution.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm Alex, your host for today, and joining me is my co-host, Jamie.\n\n**Host 2 (Jamie):** Hi everyone! I'm Jamie, and today we're exploring a groundbreaking paper that introduced the Transformer model, a game-changer in the world of sequence transduction models. Alex, can you kick us off with a bit of background on what makes this model so special?\n\n**Alex:** Absolutely, Jamie. The Transformer model, introduced in this paper, replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift is significant because it addresses some of the key limitations of RNNs, particularly their difficulty in parallelizing computation.\n\n**Jamie:** That's fascinating. So, instead of processing sequences one step at a time like RNNs, the Transformer can handle multiple parts of a sequence simultaneously?\n\n**Alex:** Exactly. This is where self-attention comes into play. It allows the model to focus on different parts of the input sequence at once, making it much more efficient and effective, especially for tasks like machine translation.\n\n**Jamie:** I see. And the paper also discusses the model's architecture in detail, right?\n\n**Alex:** Yes, the architecture is quite innovative. It consists of encoder and decoder stacks, each using multi-head attention and position-wise feed-forward networks. The multi-head attention mechanism is particularly interesting because it allows the model to attend to information from different representation subspaces simultaneously.\n\n**Jamie:** Multi-head attention sounds complex. Can you break it down a bit more?\n\n**Alex:** Sure. Think of it like having multiple sets of eyes, each looking at the input data from a different angle. This allows the model to capture various aspects of the data, leading to a richer understanding and better performance.\n\n**Jamie:** That's a great analogy. And what about the training process? How did the authors ensure the model performed well?\n\n**Alex:** They used a combination of techniques, including batched data, the Adam optimizer, and regularization methods like dropout and label smoothing. These help the model generalize better and avoid overfitting.\n\n**Jamie:** And the results were impressive, right?\n\n**Alex:** Indeed. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including English-to-German and English-to-French translations. This demonstrates the power of self-attention mechanisms in handling complex language tasks.\n\n**Jamie:** It's amazing how much this model has advanced the field. What do you think are the broader implications of this work?\n\n**Alex:** The introduction of the Transformer model has paved the way for more efficient and scalable models in natural language processing. It's also inspired further research into attention-based models, which are now a cornerstone of many AI applications.\n\n**Jamie:** That's exciting. It sounds like the future of AI is bright with these kinds of innovations. Any final thoughts, Alex?\n\n**Alex:** Just that this paper is a testament to the power of rethinking traditional approaches and embracing new ideas. The Transformer model is a perfect example of how innovation can lead to significant advancements in technology.\n\n**Jamie:** Well said. Thanks for joining us today, everyone.

I'm Alex, your host for today, and joining me is my co-host, Jamie.\n\n**Host 2 (Jamie):** Hi everyone! I'm Jamie, and today we're exploring a groundbreaking paper that introduced the Transformer model, a game-changer in the world of sequence transduction models. Alex, can you kick us off with a bit of background on what makes this model so special?\n\n**Alex:** Absolutely, Jamie. The Transformer model, introduced in this paper, replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. This shift is significant because it addresses some of the key limitations of RNNs, particularly their difficulty in parallelizing computation.\n\n**Jamie:** That's fascinating. So, instead of processing sequences one step at a time like RNNs, the Transformer can handle multiple parts of a sequence simultaneously?\n\n**Alex:** Exactly. This is where self-attention comes into play. It allows the model to focus on different parts of the input sequence at once, making it much more efficient and effective, especially for tasks like machine translation.\n\n**Jamie:** I see. And the paper also discusses the model's architecture in detail, right?\n\n**Alex:** Yes, the architecture is quite innovative. It consists of encoder and decoder stacks, each using multi-head attention and position-wise feed-forward networks. The multi-head attention mechanism is particularly interesting because it allows the model to attend to information from different representation subspaces simultaneously.\n\n**Jamie:** Multi-head attention sounds complex. Can you break it down a bit more?\n\n**Alex:** Sure. Think of it like having multiple sets of eyes, each looking at the input data from a different angle. This allows the model to capture various aspects of the data, leading to a richer understanding and better performance.\n\n**Jamie:** That's a great analogy. And what about the training process? How did the authors ensure the model performed well?\n\n**Alex:** They used a combination of techniques, including batched data, the Adam optimizer, and regularization methods like dropout and label smoothing. These help the model generalize better and avoid overfitting.\n\n**Jamie:** And the results were impressive, right?\n\n**Alex:** Indeed. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including English-to-German and English-to-French translations. This demonstrates the power of self-attention mechanisms in handling complex language tasks.\n\n**Jamie:** It's amazing how much this model has advanced the field. What do you think are the broader implications of this work?\n\n**Alex:** The introduction of the Transformer model has paved the way for more efficient and scalable models in natural language processing. It's also inspired further research into attention-based models, which are now a cornerstone of many AI applications.\n\n**Jamie:** That's exciting. It sounds like the future of AI is bright with these kinds of innovations. Any final thoughts, Alex?\n\n**Alex:** Just that this paper is a testament to the power of rethinking traditional approaches and embracing new ideas. The Transformer model is a perfect example of how innovation can lead to significant advancements in technology.\n\n**Jamie:** Well said. Thanks for joining us today, everyone.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture. Unlisted values are identical to those of the base\nmodel. All metrics are on the English-to-German translation development set, newstest2013.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

Introduction**\n\nSummary: The paper introduces the Transformer model, a new sequence transduction model that replaces traditional recurrent neural networks (RNNs) with self-attention mechanisms.\n\nNotable information: The authors highlight the limitations of RNNs in parallelizing computation and argue that self-attention can provide more efficient and effective processing of sequential data.\n\n**2. Background**\n\nSummary: This section provides a background on sequence transduction models, including recurrent neural networks (RNNs), convolutional neural networks (CNNs), and attention mechanisms.\n\nNotable information: The authors discuss the limitations of RNNs in parallelizing computation and the benefits of self-attention mechanisms, which allow for more efficient processing of sequential data.\n\n**3. Model Architecture**\n\nSummary: This section describes the Transformer model architecture, including its encoder and decoder components, as well as its use of multi-head attention and position-wise feed-forward networks.\n\nNotable information: The authors introduce the concept of multi-head attention, which allows the model to jointly attend to information from different representation subspaces at different positions. They also describe the use of position-wise feed-forward networks, which provide a way to transform the output of each position separately and identically.\n\n**3.1 Encoder and Decoder Stacks**\n\nSummary: This subsection describes the architecture of the encoder and decoder stacks in the Transformer model, including their use of multi-head attention and position-wise feed-forward networks.\n\nNotable information: The authors describe how the encoder stack processes input sequences by applying self-attention to each position separately and identically. They also describe how the decoder stack generates output sequences by applying self-attention to the previous decoder layer's output.\n\n**3.2 Attention**\n\nSummary: This section describes the attention function used in the Transformer model, including its scaled dot-product attention mechanism and multi-head attention architecture.\n\nNotable information: The authors introduce the concept of scaled dot-product attention, which allows for more efficient computation of attention weights. They also describe how multi-head attention can be used to jointly attend to information from different representation subspaces at different positions.\n\n**3.2.1 Scaled Dot-Product Attention**\n\nSummary: This subsection describes the scaled dot-product attention mechanism in more detail, including its use of scaling factors and softmax functions.\n\nNotable information: The authors describe how the scaled dot-product attention mechanism allows for more efficient computation of attention weights by scaling the dot products with a square root factor.

The best\nperforming models also connect the encoder and decoder through an attention\nmechanism. We propose a new simple network architecture, the Transformer,\nbased solely on attention mechanisms, dispensing with recurrence and convolutions\nentirely. Experiments on two machine translation tasks show these models to\nbe superior in quality while being more parallelizable and requiring significantly\nless time to train. Our model achieves 28.4 BLEU on the WMT 2014 English-\nto-German translation task, improving over the existing best results, including\nensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task,\nour model establishes a new single-model state-of-the-art BLEU score of 41.8 after\ntraining for 3.5 days on eight GPUs, a small fraction of the training costs of the\nbest models from the literature. We show that the Transformer generalizes well to\nother tasks by applying it successfully to English constituency parsing both with\nlarge and limited training data.\n∗Equal contribution.

Numerous\nefforts have since continued to push the boundaries of recurrent language models and encoder-decoder\narchitectures [38, 24, 15].\nRecurrent models typically factor computation along the symbol positions of the input and output\nsequences. Aligning the positions to steps in computation time, they generate a sequence of hidden\nstates ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently\nsequential nature precludes parallelization within training examples, which becomes critical at longer\nsequence lengths, as memory constraints limit batching across examples. Recent work has achieved\nsignificant improvements in computational efficiency through factorization tricks [21] and conditional\ncomputation [32], while also improving model performance in case of the latter. The fundamental\nconstraint of sequential computation, however, remains.\nAttention mechanisms have become an integral part of compelling sequence modeling and transduc-\ntion models in various tasks, allowing modeling of dependencies without regard to their distance in\nthe input or output sequences [2, 19]. In all but a few cases [27], however, such attention mechanisms\nare used in conjunction with a recurrent network.\nIn this work we propose the Transformer, a model architecture eschewing recurrence and instead\nrelying entirely on an attention mechanism to draw global dependencies between input and output.\nThe Transformer allows for significantly more parallelization and can reach a new state of the art in\ntranslation quality after being trained for as little as twelve hours on eight P100 GPUs.\n2\nBackground\nThe goal of reducing sequential computation also forms the foundation of the Extended Neural GPU\n[16], ByteNet [18] and ConvS2S [9], all of which use convolutional neural networks as basic building\nblock, computing hidden representations in parallel for all input and output positions. In these models,\nthe number of operations required to relate signals from two arbitrary input or output positions grows\nin the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes\nit more difficult to learn dependencies between distant positions [12]. In the Transformer this is\nreduced to a constant number of operations, albeit at the cost of reduced effective resolution due\nto averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as\ndescribed in section 3.2.\nSelf-attention, sometimes called intra-attention is an attention mechanism relating different positions\nof a single sequence in order to compute a representation of the sequence. Self-attention has been\nused successfully in a variety of tasks including reading comprehension, abstractive summarization,\ntextual entailment and learning task-independent sentence representations [4, 27, 28, 22].\nEnd-to-end memory networks are based on a recurrent attention mechanism instead of sequence-\naligned recurrence and have been shown to perform well on simple-language question answering and\nlanguage modeling tasks [34].\nTo the best of our knowledge, however, the Transformer is the first transduction model relying\nentirely on self-attention to compute representations of its input and output without using sequence-\naligned RNNs or convolution. In the following sections, we will describe the Transformer, motivate\nself-attention and discuss its advantages over models such as [17, 18] and [9].\n3\nModel Architecture\nMost competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35].\nHere, the encoder maps an input sequence of symbol representations (x1, ..., xn) to a sequence\nof continuous representations z = (z1, ..., zn). Given z, the decoder then generates an output\nsequence (y1, ..., ym) of symbols one element at a time. At each step the model is auto-regressive\n[10], consuming the previously generated symbols as additional input when generating the next.\n2\nFigure 1: The Transformer - model architecture.\nThe Transformer follows this overall architecture using stacked self-attention and point-wise, fully\nconnected layers for both the encoder and decoder, shown in the left and right halves of Figure 1,\nrespectively.\n3.1\nEncoder and Decoder Stacks\nEncoder:\nThe encoder is composed of a stack of N = 6 identical layers. Each layer has two\nsub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position-\nwise fully connected feed-forward network. We employ a residual connection [11] around each of\nthe two sub-layers, followed by layer normalization [1]. That is, the output of each sub-layer is\nLayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer\nitself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding\nlayers, produce outputs of dimension dmodel = 512.\nDecoder:\nThe decoder is also composed of a stack of N = 6 identical layers. In addition to the two\nsub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head\nattention over the output of the encoder stack. Similar to the encoder, we employ residual connections\naround each of the sub-layers, followed by layer normalization. We also modify the self-attention\nsub-layer in the decoder stack to prevent positions from attending to subsequent positions. This\nmasking, combined with fact that the output embeddings are offset by one position, ensures that the\npredictions for position i can depend only on the known outputs at positions less than i.\n3.2\nAttention\nAn attention function can be described as mapping a query and a set of key-value pairs to an output,\nwhere the query, keys, values, and output are all vectors. The output is computed as a weighted sum\n3\nScaled Dot-Product Attention\nMulti-Head Attention\nFigure 2: (left) Scaled Dot-Product Attention. (right) Multi-Head Attention consists of several\nattention layers running in parallel.\nof the values, where the weight assigned to each value is computed by a compatibility function of the\nquery with the corresponding key.\n3.2.1\nScaled Dot-Product Attention\nWe call our particular attention \"Scaled Dot-Product Attention\" (Figure 2). The input consists of\nqueries and keys of dimension dk, and values of dimension dv. We compute the dot products of the\nquery with all keys, divide each by √dk, and apply a softmax function to obtain the weights on the\nvalues.\nIn practice, we compute the attention function on a set of queries simultaneously, packed together\ninto a matrix Q. The keys and values are also packed together into matrices K and V . We compute\nthe matrix of outputs as:\nAttention(Q, K, V ) = softmax(QKT\n√dk\n)V\n(1)\nThe two most commonly used attention functions are additive attention [2], and dot-product (multi-\nplicative) attention. Dot-product attention is identical to our algorithm, except for the scaling factor\nof\n1\n√dk . Additive attention computes the compatibility function using a feed-forward network with\na single hidden layer. While the two are similar in theoretical complexity, dot-product attention is\nmuch faster and more space-efficient in practice, since it can be implemented using highly optimized\nmatrix multiplication code.\nWhile for small values of dk the two mechanisms perform similarly, additive attention outperforms\ndot product attention without scaling for larger values of dk [3]. We suspect that for large values of\ndk, the dot products grow large in magnitude, pushing the softmax function into regions where it has\nextremely small gradients 4. To counteract this effect, we scale the dot products by\n1\n√dk .\n3.2.2\nMulti-Head Attention\nInstead of performing a single attention function with dmodel-dimensional keys, values and queries,\nwe found it beneficial to linearly project the queries, keys and values h times with different, learned\nlinear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of\nqueries, keys and values we then perform the attention function in parallel, yielding dv-dimensional\n4To illustrate why the dot products get large, assume that the components of q and k are independent random\nvariables with mean 0 and variance 1. Then their dot product, q · k = Pdk\ni=1 qiki, has mean 0 and variance dk.\n4\noutput values. These are concatenated and once again projected, resulting in the final values, as\ndepicted in Figure 2.\nMulti-head attention allows the model to jointly attend to information from different representation\nsubspaces at different positions. With a single attention head, averaging inhibits this.\nMultiHead(Q, K, V ) = Concat(head1, ..., headh)W O\nwhere headi = Attention(QW Q\ni , KW K\ni , V W V\ni )\nWhere the projections are parameter matrices W Q\ni\n∈Rdmodel×dk, W K\ni\n∈Rdmodel×dk, W V\ni\n∈Rdmodel×dv\nand W O ∈Rhdv×dmodel.\nIn this work we employ h = 8 parallel attention layers, or heads. For each of these we use\ndk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost\nis similar to that of single-head attention with full dimensionality.\n3.2.3\nApplications of Attention in our Model\nThe Transformer uses multi-head attention in three different ways:\n• In \"encoder-decoder attention\" layers, the queries come from the previous decoder layer,\nand the memory keys and values come from the output of the encoder. This allows every\nposition in the decoder to attend over all positions in the input sequence. This mimics the\ntypical encoder-decoder attention mechanisms in sequence-to-sequence models such as\n[38, 2, 9].\n• The encoder contains self-attention layers. In a self-attention layer all of the keys, values\nand queries come from the same place, in this case, the output of the previous layer in the\nencoder. Each position in the encoder can attend to all positions in the previous layer of the\nencoder.\n• Similarly, self-attention layers in the decoder allow each position in the decoder to attend to\nall positions in the decoder up to and including that position. We need to prevent leftward\ninformation flow in the decoder to preserve the auto-regressive property. We implement this\ninside of scaled dot-product attention by masking out (setting to −∞) all values in the input\nof the softmax which correspond to illegal connections. See Figure 2.\n3.3\nPosition-wise Feed-Forward Networks\nIn addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully\nconnected feed-forward network, which is applied to each position separately and identically. This\nconsists of two linear transformations with a ReLU activation in between.\nFFN(x) = max(0, xW1 + b1)W2 + b2\n(2)\nWhile the linear transformations are the same across different positions, they use different parameters\nfrom layer to layer. Another way of describing this is as two convolutions with kernel size 1.\nThe dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality\ndff = 2048.\n3.4\nEmbeddings and Softmax\nSimilarly to other sequence transduction models, we use learned embeddings to convert the input\ntokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transfor-\nmation and softmax function to convert the decoder output to predicted next-token probabilities. In\nour model, we share the same weight matrix between the two embedding layers and the pre-softmax\nlinear transformation, similar to [30]. In the embedding layers, we multiply those weights by √dmodel.\n5\nTable 1: Maximum path lengths, per-layer complexity and minimum number of sequential operations\nfor different layer types. n is the sequence length, d is the representation dimension, k is the kernel\nsize of convolutions and r the size of the neighborhood in restricted self-attention.\nLayer Type\nComplexity per Layer\nSequential\nMaximum Path Length\nOperations\nSelf-Attention\nO(n2 · d)\nO(1)\nO(1)\nRecurrent\nO(n · d2)\nO(n)\nO(n)\nConvolutional\nO(k · n · d2)\nO(1)\nO(logk(n))\nSelf-Attention (restricted)\nO(r · n · d)\nO(1)\nO(n/r)\n3.5\nPositional Encoding\nSince our model contains no recurrence and no convolution, in order for the model to make use of the\norder of the sequence, we must inject some information about the relative or absolute position of the\ntokens in the sequence. To this end, we add \"positional encodings\" to the input embeddings at the\nbottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel\nas the embeddings, so that the two can be summed. There are many choices of positional encodings,\nlearned and fixed [9].\nIn this work, we use sine and cosine functions of different frequencies:\nPE(pos,2i) = sin(pos/100002i/dmodel)\nPE(pos,2i+1) = cos(pos/100002i/dmodel)\nwhere pos is the position and i is the dimension. That is, each dimension of the positional encoding\ncorresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We\nchose this function because we hypothesized it would allow the model to easily learn to attend by\nrelative positions, since for any fixed offset k, PEpos+k can be represented as a linear function of\nPEpos.\nWe also experimented with using learned positional embeddings [9] instead, and found that the two\nversions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version\nbecause it may allow the model to extrapolate to sequence lengths longer than the ones encountered\nduring training.\n4\nWhy Self-Attention\nIn this section we compare various aspects of self-attention layers to the recurrent and convolu-\ntional layers commonly used for mapping one variable-length sequence of symbol representations\n(x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈Rd, such as a hidden\nlayer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we\nconsider three desiderata.\nOne is the total computational complexity per layer. Another is the amount of computation that can\nbe parallelized, as measured by the minimum number of sequential operations required.\nThe third is the path length between long-range dependencies in the network. Learning long-range\ndependencies is a key challenge in many sequence transduction tasks. One key factor affecting the\nability to learn such dependencies is the length of the paths forward and backward signals have to\ntraverse in the network. The shorter these paths between any combination of positions in the input\nand output sequences, the easier it is to learn long-range dependencies [12]. Hence we also compare\nthe maximum path length between any two input and output positions in networks composed of the\ndifferent layer types.\nAs noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially\nexecuted operations, whereas a recurrent layer requires O(n) sequential operations. In terms of\ncomputational complexity, self-attention layers are faster than recurrent layers when the sequence\n6\nlength n is smaller than the representation dimensionality d, which is most often the case with\nsentence representations used by state-of-the-art models in machine translations, such as word-piece\n[38] and byte-pair [31] representations. To improve computational performance for tasks involving\nvery long sequences, self-attention could be restricted to considering only a neighborhood of size r in\nthe input sequence centered around the respective output position. This would increase the maximum\npath length to O(n/r). We plan to investigate this approach further in future work.\nA single convolutional layer with kernel width k < n does not connect all pairs of input and output\npositions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels,\nor O(logk(n)) in the case of dilated convolutions [18], increasing the length of the longest paths\nbetween any two positions in the network. Convolutional layers are generally more expensive than\nrecurrent layers, by a factor of k. Separable convolutions [6], however, decrease the complexity\nconsiderably, to O(k · n · d + n · d2). Even with k = n, however, the complexity of a separable\nconvolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer,\nthe approach we take in our model.\nAs side benefit, self-attention could yield more interpretable models. We inspect attention distributions\nfrom our models and present and discuss examples in the appendix. Not only do individual attention\nheads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic\nand semantic structure of the sentences.\n5\nTraining\nThis section describes the training regime for our models.\n5.1\nTraining Data and Batching\nWe trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million\nsentence pairs. Sentences were encoded using byte-pair encoding [3], which has a shared source-\ntarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT\n2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece\nvocabulary [38]. Sentence pairs were batched together by approximate sequence length. Each training\nbatch contained a set of sentence pairs containing approximately 25000 source tokens and 25000\ntarget tokens.\n5.2\nHardware and Schedule\nWe trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using\nthe hyperparameters described throughout the paper, each training step took about 0.4 seconds. We\ntrained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the\nbottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps\n(3.5 days).\n5.3\nOptimizer\nWe used the Adam optimizer [20] with β1 = 0.9, β2 = 0.98 and ϵ = 10−9. We varied the learning\nrate over the course of training, according to the formula:\nlrate = d−0.5\nmodel · min(step_num−0.5, step_num · warmup_steps−1.5)\n(3)\nThis corresponds to increasing the learning rate linearly for the first warmup_steps training steps,\nand decreasing it thereafter proportionally to the inverse square root of the step number. We used\nwarmup_steps = 4000.\n5.4\nRegularization\nWe employ three types of regularization during training:\n7\nTable 2: The Transformer achieves better BLEU scores than previous state-of-the-art models on the\nEnglish-to-German and English-to-French newstest2014 tests at a fraction of the training cost.\nModel\nBLEU\nTraining Cost (FLOPs)\nEN-DE\nEN-FR\nEN-DE\nEN-FR\nByteNet [18]\n23.75\nDeep-Att + PosUnk [39]\n39.2\n1.0 · 1020\nGNMT + RL [38]\n24.6\n39.92\n2.3 · 1019\n1.4 · 1020\nConvS2S [9]\n25.16\n40.46\n9.6 · 1018\n1.5 · 1020\nMoE [32]\n26.03\n40.56\n2.0 · 1019\n1.2 · 1020\nDeep-Att + PosUnk Ensemble [39]\n40.4\n8.0 · 1020\nGNMT + RL Ensemble [38]\n26.30\n41.16\n1.8 · 1020\n1.1 · 1021\nConvS2S Ensemble [9]\n26.36\n41.29\n7.7 · 1019\n1.2 · 1021\nTransformer (base model)\n27.3\n38.1\n3.3 · 1018\nTransformer (big)\n28.4\n41.8\n2.3 · 1019\nResidual Dropout\nWe apply dropout [33] to the output of each sub-layer, before it is added to the\nsub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the\npositional encodings in both the encoder and decoder stacks. For the base model, we use a rate of\nPdrop = 0.1.\nLabel Smoothing\nDuring training, we employed label smoothing of value ϵls = 0.1 [36]. This\nhurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.\n6\nResults\n6.1\nMachine Translation\nOn the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big)\nin Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0\nBLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is\nlisted in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model\nsurpasses all previously published models and ensembles, at a fraction of the training cost of any of\nthe competitive models.\nOn the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0,\noutperforming all of the previously published single models, at less than 1/4 the training cost of the\nprevious state-of-the-art model. The Transformer (big) model trained for English-to-French used\ndropout rate Pdrop = 0.1, instead of 0.3.\nFor the base models, we used a single model obtained by averaging the last 5 checkpoints, which\nwere written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We\nused beam search with a beam size of 4 and length penalty α = 0.6 [38]. These hyperparameters\nwere chosen after experimentation on the development set. We set the maximum output length during\ninference to input length + 50, but terminate early when possible [38].\nTable 2 summarizes our results and compares our translation quality and training costs to other model\narchitectures from the literature. We estimate the number of floating point operations used to train a\nmodel by multiplying the training time, the number of GPUs used, and an estimate of the sustained\nsingle-precision floating-point capacity of each GPU 5.\n6.2\nModel Variations\nTo evaluate the importance of different components of the Transformer, we varied our base model\nin different ways, measuring the change in performance on English-to-German translation on the\n5We used values of 2.8, 3.7, 6.0 and 9.5 TFLOPS for K80, K40, M40 and P100, respectively.\n8\nTable 3: Variations on the Transformer architecture.

We used beam search as described in the previous section, but no\ncheckpoint averaging. We present these results in Table 3.\nIn Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions,\nkeeping the amount of computation constant, as described in Section 3.2.2. While single-head\nattention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.\nIn Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This\nsuggests that determining compatibility is not easy and that a more sophisticated compatibility\nfunction than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected,\nbigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our\nsinusoidal positional encoding with learned positional embeddings [9], and observe nearly identical\nresults to the base model.\n6.3\nEnglish Constituency Parsing\nTo evaluate if the Transformer can generalize to other tasks we performed experiments on English\nconstituency parsing. This task presents specific challenges: the output is subject to strong structural\nconstraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence\nmodels have not been able to attain state-of-the-art results in small-data regimes [37].\nWe trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the\nPenn Treebank [25], about 40K training sentences. We also trained it in a semi-supervised setting,\nusing the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences\n[37]. We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens\nfor the semi-supervised setting.\nWe performed only a small number of experiments to select the dropout, both attention and residual\n(section 5.4), learning rates and beam size on the Section 22 development set, all other parameters\nremained unchanged from the English-to-German base translation model. During inference, we\n9\nTable 4: The Transformer generalizes well to English constituency parsing (Results are on Section 23\nof WSJ)\nParser\nTraining\nWSJ 23 F1\nVinyals & Kaiser el al.

We used a beam size of 21 and α = 0.3\nfor both WSJ only and the semi-supervised setting.\nOur results in Table 4 show that despite the lack of task-specific tuning our model performs sur-\nprisingly well, yielding better results than all previously reported models with the exception of the\nRecurrent Neural Network Grammar [8].\nIn contrast to RNN sequence-to-sequence models [37], the Transformer outperforms the Berkeley-\nParser [29] even when training only on the WSJ training set of 40K sentences.\n7\nConclusion\nIn this work, we presented the Transformer, the first sequence transduction model based entirely on\nattention, replacing the recurrent layers most commonly used in encoder-decoder architectures with\nmulti-headed self-attention.\nFor translation tasks, the Transformer can be trained significantly faster than architectures based\non recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014\nEnglish-to-French translation tasks, we achieve a new state of the art. In the former task our best\nmodel outperforms even all previously reported ensembles.\nWe are excited about the future of attention-based models and plan to apply them to other tasks. We\nplan to extend the Transformer to problems involving input and output modalities other than text and\nto investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs\nsuch as images, audio and video. Making generation less sequential is another research goals of ours.\nThe code we used to train and evaluate our models is available at https://github.com/\ntensorflow/tensor2tensor.\nAcknowledgements\nWe are grateful to Nal Kalchbrenner and Stephan Gouws for their fruitful\ncomments, corrections and inspiration.\nReferences\n[1] Jimmy Lei Ba, Jamie Ryan Kiros, and Geoffrey E Hinton.

I'm Alex, and joining me is my co-host, Jamie. Today, we're exploring a groundbreaking development in the field of machine learning—the Transformer model.\n\n**Host 2 (Jamie):** That's right, Alex. The Transformer model has been making waves in the AI community, and for good reason. It's a new sequence transduction model that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. But what does that mean, exactly?\n\n**Alex:** Great question, Jamie. Traditionally, RNNs have been used for processing sequential data, like language. However, they have limitations, especially when it comes to parallelizing computation. The Transformer model addresses these limitations by using self-attention mechanisms, which allow for more efficient and effective processing.\n\n**Jamie:** So, it's all about improving efficiency and parallelization. But how does the Transformer model actually work?\n\n**Alex:** The model's architecture is quite fascinating. It consists of encoder and decoder components, each using multi-head attention and position-wise feed-forward networks. Multi-head attention allows the model to attend to information from different representation subspaces at different positions, which is a key innovation.\n\n**Jamie:** And what about the training process? How do they ensure the model performs well?\n\n**Alex:** The authors used a combination of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. They also emphasize the importance of tuning hyperparameters carefully to achieve optimal performance.\n\n**Jamie:** It sounds like a lot of work, but the results speak for themselves, right?\n\n**Alex:** Absolutely. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including English-to-German and English-to-French translations. It's a testament to the power of self-attention mechanisms.\n\n**Jamie:** And what about its applications beyond translation?\n\n**Alex:** The model has shown promise in other areas, like English constituency parsing, where it can handle long-range dependencies and generalize to other tasks. It's a versatile tool with a lot of potential.\n\n**Jamie:** It's exciting to think about where this technology could go in the future.

I'm Alex, and joining me is my co-host, Jamie. Today, we're exploring a groundbreaking development in the field of machine learning—the Transformer model.\n\n**Host 2 (Jamie):** That's right, Alex. The Transformer model has been making waves in the AI community, and for good reason. It's a new sequence transduction model that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. But what does that mean, exactly?\n\n**Alex:** Great question, Jamie. Traditionally, RNNs have been used for processing sequential data, like language. However, they have limitations, especially when it comes to parallelizing computation. The Transformer model addresses these limitations by using self-attention mechanisms, which allow for more efficient and effective processing.\n\n**Jamie:** So, it's all about improving efficiency and parallelization. But how does the Transformer model actually work?\n\n**Alex:** The model's architecture is quite fascinating. It consists of encoder and decoder components, each using multi-head attention and position-wise feed-forward networks. Multi-head attention allows the model to attend to information from different representation subspaces at different positions, which is a key innovation.\n\n**Jamie:** And what about the training process? How do they ensure the model performs well?\n\n**Alex:** The authors used a combination of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. They also emphasize the importance of tuning hyperparameters carefully to achieve optimal performance.\n\n**Jamie:** It sounds like a lot of work, but the results speak for themselves, right?\n\n**Alex:** Absolutely. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including English-to-German and English-to-French translations. It's a testament to the power of self-attention mechanisms.\n\n**Jamie:** And what about its applications beyond translation?\n\n**Alex:** The model has shown promise in other areas, like English constituency parsing, where it can handle long-range dependencies and generalize to other tasks. It's a versatile tool with a lot of potential.\n\n**Jamie:** It's exciting to think about where this technology could go in the future. Any final thoughts, Alex?\n\n**Alex:** The Transformer model is a significant step forward in machine learning, offering new possibilities for processing sequential data. As research continues, we can expect even more innovative applications and improvements.\n\n**Jamie:** Thanks for breaking it down, Alex.

I'm Alex.\n\nHOST 2 (Jamie): And I'm Jamie. Today we're diving into a fascinating topic in the world of machine learning—the Transformer model. It's been a game-changer in how we process sequential data.\n\nHOST 1: Let's start with the basics. The Transformer model was introduced as a new sequence transduction model that replaces traditional recurrent neural networks, or RNNs, with self-attention mechanisms. Jamie, why is this shift significant?\n\nHOST 2: Well, Alex, RNNs have been the standard for sequence tasks, but they have limitations, especially in parallelizing computation. The Transformer model's use of self-attention allows for more efficient processing, which is crucial for tasks like language translation.\n\nHOST 1: Exactly. The paper's introduction highlights these advantages. Moving on to the background, it discusses sequence transduction models, including RNNs, CNNs, and attention mechanisms. What stands out to you here?\n\nHOST 2: The key takeaway is the limitations of RNNs and the benefits of self-attention. Self-attention mechanisms allow for more efficient processing by focusing on different parts of the input data simultaneously.\n\nHOST 1: That brings us to the model architecture. The Transformer model consists of encoder and decoder stacks, using multi-head attention and position-wise feed-forward networks. Can you break that down for us?\n\nHOST 2: Sure! Multi-head attention allows the model to attend to information from different representation subspaces at different positions. Position-wise feed-forward networks transform the output of each position separately, enhancing the model's ability to process data.\n\nHOST 1: And the attention mechanisms are crucial here. The scaled dot-product attention and multi-head attention work together to efficiently compute attention weights and process data in parallel.\n\nHOST 2: Right. The training section outlines the use of batched data, the Adam optimizer, and regularization techniques like dropout and label smoothing. These methods optimize the model's performance.\n\nHOST 1: The results speak for themselves. The Transformer model achieved state-of-the-art performance on several machine translation tasks, including English-to-German and English-to-French translations.\n\nHOST 2: It's impressive how the model handles long-range dependencies and generalizes to other tasks. The conclusion suggests future research directions, like exploring more attention-based models and refining the architecture.\n\nHOST 1: Exciting times ahead for machine learning! That's all for today's episode.\n\nHOST 2: Thanks for joining us on Research Roundup.
