Trade-off between Inference Latency and Accuracy in mT5 for Zero-Shot Cross-Lingual Evaluation

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 trade-off between inference latency and accuracy when using English intermediate-task training on mT5 for zero-shot cross-lingual evaluation on XTREME-R compared to direct fine-tuning, as measured by throughput (tokens/second) and average score improvement?
