XLM-R-large Performance in Zero-Shot Cross-Lingual NER: Intermediate Task Diversity Analysis

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: How does the choice of intermediate task diversity (e.g., single vs. multiple tasks across different NLP subtasks) impact the F1 score of XLM-R-large on XTREME-R's NER task when evaluated in zero-shot cross-lingual settings?
