Zero-shot Cross-lingual Performance of mT5-XXL on XTREME-R Subtasks with 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: How does the zero-shot cross-lingual performance of mT5-XXL on XTREME-R subtasks compare when using intermediate-task training on multiple languages (e.g., Spanish, French) instead of solely English, measured by accuracy gains per subtask?
