Linguistic Similarity and Zero-Shot Cross-Lingual Transfer in XTREME

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 the effectiveness of English intermediate-task training for zero-shot cross-lingual transfer depend on the linguistic similarity between the target language and English, and how does this correlation affect performance on XTREME?
