Towards Understanding and Improving Knowledge Distillation for Neural Machine Translation (2023.acl-long)
Copied to clipboard
| Challenge: | Existing knowledge distillation techniques for neural machine translation lack special treatment on the top-1 information, which is limiting the potential of KD. |
| Approach: | They propose a method to distill knowledge from top-1 predictions of teachers and a technique to infuse more additional knowledge by distilling on the data without ground-truth targets. |
| Outcome: | The proposed method outperforms the vanilla word-level KD and outperfies the existing methods on three different students with different capacity gaps. |
Adversarially Improving NMT Robustness to ASR Errors with Confusion Sets (2022.aacl-short)
Copied to clipboard
| Challenge: | Existing methods for robustness against homophone errors are limited to homophones . substitution errors are the most common errors in NMT models . |
| Approach: | They propose an adversarial example generation method based on confusion sets that contain words easily confusable with a target word by ASR to conduct adversarially training for NMT models. |
| Outcome: | The proposed method improves on the clean test set and can be used in real-world scenarios. |
