Intermediate-Task Combinations for Zero-Shot Cross-Lingual Transfer on XTREME-R

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 effectiveness of intermediate-task training vary when using different combinations of intermediate tasks (e.g., question answering, natural language inference) for zero-shot cross-lingual transfer on the XTREME-R benchmark, and which combination yields the highest average performance across languages?
