Diversity of Intermediate Cross-Lingual Tasks and Zero-Shot Accuracy in XTREME-R Low-Resource Languages

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 increasing the diversity of intermediate cross-lingual tasks impact zero-shot accuracy on XTREME-R low-resource languages compared to single-task English fine-tuning?
