LoRA Study Maps Asymmetric Transfer Across Tasks and Languages
Researchers ran a controlled LoRA fine-tuning experiment to see how gains from training on one task or language carry over to others. The work finds that transfer between tasks and languages is uneven rather than symmetric, meaning improvements in one setting do not reliably help elsewhere. The findings point to limits in assuming that fine-tuning benefits generalize broadly across multilingual, multi-task models.
