Zero-shot Cross-lingual Performance on XTREME-R Benchmarks: English-only vs. Multilingual Intermediate-task Training

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 zero-shot cross-lingual performance on XTREME-R benchmarks compare when intermediate-task training is conducted on English-only datasets versus multilingual datasets of varying sizes, measured by average accuracy across languages?
