Unverified50% confidenceFactExact time
LoRA is currently the most mainstream method in parameter-efficient fine-tuning (PEFT); its core approach is to insert a pair of low-rank matrices (typically with a rank of 4 to 64) alongside the weight matrices of Transformer layers, training only these two small matrices.
