Cross-lingual Retrieval Accuracy Variations in XTREME-R with Intermediate Task Selection

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 choice of intermediate language understanding task (e.g., NLI vs. QA) affect zero-shot cross-lingual retrieval accuracy on XTREME-R when using multilingual vs. monolingual English fine-tuning?
