BLEURT Has Universal Translations: An Analysis of Automatic Metrics by Minimum Risk Training

ACL 2023long

Automatic metrics play a crucial role in machine translation. Despite the widespread use of n-gram-based metrics, there has been a recent surge in the development of pre-trained model-based metrics that focus on measuring sentence semantics. However, these neural metrics, while achieving higher corr…

Improving Speech Translation by Fusing Speech and Text

EMNLP 2023long findings

In speech translation, leveraging multimodal data to improve model performance and address limitations of individual modalities has shown significant effectiveness. In this paper, we harness the complementary strengths of speech and text to improve speech translation. However, speech and text are di…

Selective Knowledge Distillation for Non-Autoregressive Neural Machine Translation

AAAI 2023technical

Benefiting from the sequence-level knowledge distillation, the Non-Autoregressive Transformer (NAT) achieves great success in neural machine translation tasks. However, existing knowledge distillation has side effects, such as propagating errors from the teacher to NAT students, which may limit fur…

Rethinking Document-level Neural Machine Translation

ACL 2022findings

This paper does not aim at introducing a novel model for document-level neural machine translation. Instead, we head back to the original Transformer model and hope to answer the following question: Is the capacity of current models strong enough for document-level translation? Interestingly, we obs…

Autocorrect in the Process of Translation — Multi-task Learning Improves Dialogue Machine Translation

NAACL 2021industry

Automatic translation of dialogue texts is a much needed demand in many real life scenarios. However, the currently existing neural machine translation delivers unsatisfying results. In this paper, we conduct a deep analysis of a dialogue corpus and summarize three major issues on dialogue translati…

Counter-Interference Adapter for Multilingual Machine Translation

EMNLP 2021finding

Developing a unified multilingual model has been a long pursuing goal for machine translation. However, existing approaches suffer from performance degradation - a single multilingual model is inferior to separately trained bilingual ones on rich-resource languages. We conjecture that such a phenome…

Finding Sparse Structures for Domain Specific Neural Machine Translation

AAAI 2021technical

Neural machine translation often adopts the fine-tuning approach to adapt to specific domains. However, nonrestricted fine-tuning can easily degrade on the general domain and over-fit to the target domain. To mitigate the issue, we propose Prune-Tune, a novel domain adaptation method via gradual pru…

Secoco: Self-Correcting Encoding for Neural Machine Translation

EMNLP 2021finding

This paper presents Self-correcting Encoding (Secoco), a framework that effectively deals with noisy input for robust neural machine translation by introducing self-correcting predictors. Different from previous robust approaches, Secoco enables NMT to explicitly correct noisy inputs and delete spec…
