Researchers have introduced a new method called LoRA+ for fine-tuning large pre-trained models, aiming to improve the balance between task-specific performance and the retention of pre-trained knowledge. This approach focuses on fine-tuning intermediate principal components of weight matrices, which the study found offers a better trade-off than methods that target the first or last components. Empirical studies across various computer vision and natural language processing tasks demonstrated that LoRA+ achieves higher accuracy while reducing the forgetting of original knowledge, providing practical guidelines for initializing LoRA methods.
