Multilingual Intermediate-Task Training Effects on mT5 Zero-Shot Cross-Lingual Performance

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: How does intermediate-task training on multilingual (non-English) intermediate tasks compare to English-only intermediate tasks in improving zero-shot cross-lingual performance of mT5 on the XTREME benchmark, as measured by XNLI accuracy and XCOPA score differences?
