Intermediate-Task Training with Adapter-Based Fine-Tuning for Multilingual LLM Reasoning on MMLU

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 combining intermediate-task training with adapter-based fine-tuning improve the reasoning capabilities of LLMs on the MMLU benchmark for non-English languages compared to full fine-tuning?
