Scaling Intermediate-Task Training Data Effects on FLAN-T5 Zero-Shot Cross-Lingual Performance

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 size of English intermediate-task training data from 100K to 2M examples affect the zero-shot cross-lingual performance of FLAN-T5 on XTREME-R tasks, measured by EM and F1 scores?
