Scaling Multilingual Models for Zero-Shot Cross-Lingual Code Generation

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: To what extent does scaling the size of multilingual models (e.g., CodeT5-3B vs. CodeT5-770M) impact the effectiveness of English intermediate-task training for zero-shot cross-lingual code generation in terms of BLEU score improvements on CodeXGLUE?
