Scaling Intermediate Tasks and Zero-Shot Accuracy in mT5-XXL on 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 the number of English intermediate tasks from nine to fifty affect zero-shot accuracy on XTREME-R for mT5-XXL compared to single-task fine-tuning?
