Scaling Model Size Effects on Generalization Gaps in Multilingual Fine-Tuning for XTREME-R Zero-Shot Evaluation

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 effect of scaling model size (e.g., 1B vs. 10B parameters) on the generalization gap between English-only and multilingual intermediate-task fine-tuning for zero-shot cross-lingual evaluation on XTREME-R, measured by F1 score improvements?
