Zero-shot Cross-lingual Transfer in Multilingual Pretrained Models on XTREME-R

Intermediate-task training---fine-tuning a pretrained model on an intermediate task before fine-tuning again on the target task---often improves model performance substantially on language understanding tasks in monolingual English settings. We investigate whether English intermediate-task training is still helpful on non-English target tasks. Using nine intermediate language-understanding tasks, we evaluate intermediate-task transfer in a zero-shot cross-lingual setting on the XTREME benchmark. We see large improvements from intermediate training on the BUCC and Tatoeba sentence retrieval tas

Research goal: Does the zero-shot cross-lingual transfer benefit of English intermediate-task fine-tuning extend to multilingual pretrained models (e.g., mT5, XLM-R) when evaluated on XTREME-R for robustness?
