Dataset Scaling and Zero-Shot Cross-Lingual Transfer in XTREME Subsets

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: To what extent does scaling the size of the intermediate-task training dataset (e.g., 10k vs. 100k examples) impact zero-shot cross-lingual transfer performance on specialized XTREME subsets, and is there a diminishing returns effect?
