Multimodal Intermediate-Task Training for Zero-Shot Cross-Lingual Transfer in mT5 on XTREME Tasks

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: Does multimodal intermediate-task training (e.g., vision-language tasks) improve the zero-shot cross-lingual transfer performance of mT5 on XTREME tasks compared to text-only intermediate tasks, measured by accuracy and alignment robustness metrics?
