LoRA-GA$^2$: Low Rank Adaptation with Multi-step Gradient Adaptive Alignment
Researchers have proposed a new fine-tuning method called LoRA-GA$^2$, which aims to close the performance gap between low-rank adaptation (LoRA) and full fine-tuning. The approach uses multi-step gradient information to better align updates with the principal directions of full fine-tuning. This results in improved performance on several benchmarks, including GLUE, GSM8K, and HumanEval, while maintaining the efficiency advantages of LoRA.
