Zero-shot cross-lingual performance enhancement in multilingual models via hybrid batch fine-tuning

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 the zero-shot cross-lingual performance of multilingual models on XTREME-R improve when using a hybrid batch of English and non-English intermediate tasks compared to sequential fine-tuning, measured by accuracy and inference latency?
