Reinforcement Learning for Task Sequence Optimization in XTREME-R Cross-Lingual Zero-Shot Performance

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 task sequence optimization (e.g., using reinforcement learning) on cross-lingual zero-shot performance in XTREME-R compared to fixed intermediate-task sequences?
