Mixed-language intermediate-task training for zero-shot cross-lingual transfer 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 impact of mixed-language intermediate-task training (combining English and target languages) on zero-shot cross-lingual transfer performance compared to English-only training, evaluated using XTREME-R F1 scores?
