Enhanced Zero-Shot Cross-Lingual Transfer via Multilingual Intermediate Task Training

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 combining intermediate training on both English and non-English intermediate tasks (e.g., NLI, QA) further enhance zero-shot cross-lingual transfer on XTREME-R compared to English-only or monolingual intermediate training, measured by relative accuracy gains on non-English target tasks?
