Cross-lingual Transfer Performance of mT5 and XLM-R with Expanded Training Data

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 size of intermediate language-understanding training datasets from 10k to 100k samples affect the zero-shot cross-lingual transfer performance of mT5 and XLM-R on the XTREME benchmark as measured by average mAUROC scores?
