Multilingual Word Alignment Tasks for Zero-Shot Cross-Lingual Transfer Efficiency on XCOPA

Multilingual pre-trained models have achieved remarkable performance on cross-lingual transfer learning. Some multilingual models such as mBERT, have been pre-trained on unlabeled corpora, therefore the embeddings of different languages in the models may not be aligned very well. In this paper, we aim to improve the zero-shot cross-lingual transfer performance by proposing a pre-training task named Word-Exchange Aligning Model (WEAM), which uses the statistical alignment information as the prior knowledge to guide cross-lingual word prediction. We evaluate our model on multilingual machine rea

Research goal: Does incorporating multilingual word alignment tasks (e.g., WEAM) alongside English tasks improve zero-shot cross-lingual transfer efficiency on the XCOPA benchmark compared to English-only intermediate training?
