Impact of Pretrained Multilingual LLM Size on Zero-Shot Cross-Lingual Transfer Effectiveness

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 scaling the size of the pretrained multilingual LLM (e.g., 7B vs. 13B parameters) impact the effectiveness of multilingual intermediate-task training for zero-shot cross-lingual transfer on XTREME-R?
