Scaling Multilingual vs. English Intermediate Tasks for XTREME-R Zero-Shot Transfer

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 scaling the number of multilingual intermediate tasks improve zero-shot cross-lingual transfer performance on XTREME-R more effectively than scaling the number of English intermediate tasks, as measured by F1-score improvements?
