Scaling Multilingual Intermediate Tasks for Low-Resource Languages: Impact on Zero-Shot Transfer Variance 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 scaling multilingual intermediate tasks across low-resource languages affect zero-shot transfer accuracy variance on XTREME-R compared to English-only intermediate training?
