Exploring the Importance of Source Text in Automatic Post-Editing for Context-Aware Machine Translation

1 code implementation NoDaLiDa 2021 Chaojun Wang, Christian Hardmeier, Rico Sennrich

They also highlight blind spots in automatic methods for targeted evaluation and demonstrate the need for human assessment to evaluate document-level translation quality reliably.

Progressive Translation: Improving Domain Robustness of Neural Machine Translation with Intermediate Sequences

1 code implementation16 May 2023 Chaojun Wang, Yang Liu, Wai Lam

Furthermore, we introduce a full-permutation multi-task learning to alleviate the spurious causal relations from intermediate sequences to the target, which results from exposure bias.

On Exposure Bias, Hallucination and Domain Shift in Neural Machine Translation

1 code implementation ACL 2020 Chaojun Wang, Rico Sennrich

In experiments on three datasets with multiple test domains, we show that exposure bias is partially to blame for hallucinations, and that training with Minimum Risk Training, which avoids exposure bias, can mitigate this.
