Intermediate-Task Selection Strategies for Zero-Shot Cross-Lingual Transfer in XTREME-R Benchmarking of LLMs

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 different intermediate-task selection strategies (e.g., task diversity, task difficulty) on zero-shot cross-lingual transfer performance on the XTREME-R benchmark for LLMs of varying sizes (e.g., 7B vs 70B parameters)?
