On the Language Coverage Bias for Neural Machine Translation (2021.findings-acl)
Copied to clipboard
| Challenge: | Language coverage bias is important for neural machine translation because of the target-original training data. |
| Approach: | They propose two approaches to alleviate the language coverage bias problem by explicitly distinguishing between the source-and target-original training data. |
| Outcome: | The proposed methods improve translation tasks on both back-and forward-translation and their tagged variants. |
Neural Machine Translation with Decoding History Enhanced Attention (C18-1)
Copied to clipboard
| Challenge: | Neural machine translation with source-side attention has been criticized for its poor memory performance. |
| Approach: | They propose to use a Decoding History Enhanced Attention mechanism to render NMT models better at selecting both source-side and target-side information. |
