This ignores discourse links and can hurt the cohesion of a translated document. The authors add document context to a Transformer through a hierarchical attention network (HAN) that reuses the model's own hidden states from the k previous sentences instead… 2. **[Deep Encoder, Shallow Decoder: Reevaluating Non-autoregressive Machine Translation](https://md.research.elamur.ai/free/en/papers/kasai-2020-deep-encoder-shallow-decoder-reevaluating/)** *(2020 · 132 citations)* Non-autoregressive translation (NAR) is often presented as a faster alternative to standard autoregressive (AR) Transformers, with only a small loss in quality. ## Co-authors here 5 co-authors with a page, the most papers together first. - [Hao Peng](https://md.research.elamur.ai/free/en/authors/hao-peng/) - [James Cross](https://md.research.elamur.ai/free/en/authors/james-cross/) - [James Henderson](https://md.research.elamur.ai/free/en/authors/james-henderson/) - [Jungo Kasai](https://md.research.elamur.ai/free/en/authors/jungo-kasai/) - [Noah A.
