Scaling Pretrained Model Size and Cross-Lingual Alignment Retention in Fine-Tuned Zero-Shot Transfer

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 scaling pretrained model size from base to large variants impact the retention of cross-lingual alignment when fine-tuned on diverse intermediate language-understanding tasks before zero-shot transfer on XTREME?
