Mixed vs. Sequential Batch Training in Intermediate-Task Fine-Tuning for XTREME-R Zero-Shot Cross-Lingual Accuracy

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: What is the impact of using a mixed batch of intermediate English task samples versus sequential batch training during intermediate-task fine-tuning on the downstream zero-shot cross-lingual accuracy of XTREME-R benchmarks?
