A Bidirectional Transformer Based Alignment Model for Unsupervised Word Alignment (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods for learning word alignment include statistical word aligners (e.g. GIZA++) Existing word alignment models employ a target-to-source attention mechanism which can provide rough word alignments but with a low accuracy. |
| Approach: | They propose a bidirectional Transformer based alignment model for unsupervised learning of the word alignment task. |
| Outcome: | The proposed model outperforms both previous neural word alignment approaches and the popular statistical word aligner GIZA++ on three word alignment tasks. |
G-Transformer for Document-Level Machine Translation (2021.acl-long)

| Challenge: | Existing work extends translation unit from single sentence to multiple sentences. |
| Approach: | They propose to introduce locality assumption as an inductive bias into Transformer and reduce the hypothesis space of attention from target to source. |
| Outcome: | The proposed model achieves state-of-the-art BLEU scores on three benchmark datasets. |
