BoolQ Proportion Effects on Zero-Shot Cross-Lingual Retrieval in 1B-Parameter Encoder Models

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 increasing the proportion of BoolQ in the intermediate-task training mix (e.g., 30% vs. 50%) improve the zero-shot cross-lingual retrieval performance (MRR) of encoder-only models with 1B parameters on XTREME-R?
