mT5 Performance Variability in Zero-Shot Cross-Lingual Transfer via 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 English language understanding tasks affect the zero-shot cross-lingual transfer performance of mT5 on specific XTREME benchmark tasks when evaluated using per-task F1 score instead of exact match accuracy?
