Degradation of Zero-Shot Performance on Low-Resource Languages via English Intermediate-Task Training 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: To what extent does English intermediate-task training degrade zero-shot performance on low-resource languages within XTREME-R compared to high-resource languages?
