Rethinking Parameter Sharing for LLM Fine-Tuning with Multiple LoRAs (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for large language models use parameter-efficient techniques such as Low-Rank Adaptation (LoRA) prior studies suggest that the inner A matrices are highly similar during training and therefore suitable for sharing. |
| Approach: | They propose an asymmetric multi-LoRA design with multiple A matrices and a single shared B in multi-task fine-tuning. |
| Outcome: | The proposed methods achieve more balanced performance across tasks with comparable or superior average accuracy relative to existing methods. |
