Label-aware Contrastive Learning for Zero-shot Crosslingual NLI Performance

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: How does integrating label-aware contrastive learning with cross-lingual pre-trained models (e.g., XLM-R, mBERT) improve zero-shot performance on the Crosslingual Natural Language Understanding (XNLI) benchmark compared to traditional fine-tuning methods?
