Contrastive Learning with Synthetic Cross-Lingual Pairs for Zero-Shot Transfer on XTREME-R

Recently, although pre-trained language models have achieved great success on multilingual NLP (Natural Language Processing) tasks, the lack of training data on many tasks in low-resource languages still limits their performance. One effective way of solving that problem is to transfer knowledge from rich-resource languages to low-resource languages. However, many previous works on cross-lingual transfer rely heavily on the parallel corpus or translation models, which are often difficult to obtain. We propose a novel approach to conduct zero-shot cross-lingual transfer with a pre-trained model

Research goal: How does contrastive learning with synthetic cross-lingual sentence pairs impact zero-shot cross-lingual transfer accuracy on XTREME-R when compared to traditional parallel corpus-based alignment methods?
