Impact of Reasoning-to-Question-Answering Task Ratios on Zero-Shot Cross-Lingual Accuracy of mT5 Models

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 varying the ratio of reasoning vs. question-answering tasks in intermediate-task training affect the zero-shot cross-lingual accuracy of mT5 models on the XTREME-R benchmark, measured by F1 score and compared to single-task training?
