Comparative Analysis of Multilingual and English-Only Intermediate-Task Training for Zero-Shot Cross-Lingual Transfer in 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: How does the performance of multilingual intermediate-task training compare to English-only intermediate-task training on zero-shot cross-lingual transfer tasks in XTREME-R, particularly on low-resource languages?
