Abstract

While monolingual data has been shown to be useful in improving bilingual neural machine translation (NMT), effectively and efficiently leveraging monolingual data for Multilingual NMT (MNMT) systems is a less explored area.In this work, we propose a multi-task learning (MTL) framework that jointly trains the model with the translation task on bitext data and two denoising tasks on the monolingual data.We conduct extensive empirical studies on MNMT systems with 10 language pairs from WMT datasets.We show that the proposed approach can effectively improve the translation quality for both high-resource and low-resource languages with large margin, achieving significantly better results than the individual bilingual models.We also demonstrate the efficacy of the proposed approach in the zero-shot setup for language pairs without bitext training data.Furthermore, we show the effectiveness of MTL over pre-training approaches for both NMT and cross-lingual transfer learning NLU tasks; the proposed approach outperforms massive scale models trained on single task.

  • Multilingual modeling has not been systematically explored for code translation.

    “Multilingual modeling shows great potential in neural machine translation (Aharoni et al., 2019;Wang et al., 2020;Zhu et al., 2023), but it has not been systematically explored for code translation.”

  • Multilingual modeling has been pivotal in broadening the applicability of neural machine translation, primarily evidenced in enhancing performance of low-resource languages and cross-language transfer learning.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
