Scaling Effects on Zero-Shot Cross-Lingual Robustness in XTREME-R with Intermediate-Task Training

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 the scaling of model size (e.g., 110M vs. 1B parameters) affect the robustness of zero-shot cross-lingual performance on XTREME-R when intermediate-task training is applied, measured by accuracy variability across language families?
