Diminishing Performance Gains in Intermediate-Task Training for XTREME-R Retrieval with Model Scaling

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 performance gain from English intermediate-task training on XTREME-R sentence retrieval tasks diminish when the base pretrained model scale increases from 100M to 10B parameters?
