Impact of Domain Adaptation on Zero-Shot Cross-Lingual Transfer with Hybrid Batch Training versus LaBSE on PAWS-X

Pre-trained multilingual language encoders, such as multilingual BERT and XLM-R, show great potential for zero-shot cross-lingual transfer. However, these multilingual encoders do not precisely align words and phrases across languages. Especially, learning alignments in the multilingual embedding space usually requires sentence-level or word-level parallel corpora, which are expensive to be obtained for low-resource languages. An alternative is to make the multilingual encoders more robust; when fine-tuning the encoder using downstream task, we train the encoder to tolerate noise in the contex

Research goal: What is the impact of domain adaptation on zero-shot cross-lingual transfer performance when using the hybrid batch training strategy versus LaBSE on the PAWS-X benchmark for low-resource languages?
