Sequence Depth in Intermediate-Task Fine-Tuning and Zero-Shot Accuracy 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 the sequence depth of English intermediate-task fine-tuning affect the downstream zero-shot accuracy of Flan-T5 on XTREME-R's language understanding tasks compared to direct fine-tuning?
