Beyond Higher Rank: Token-wise Input-Output Projections for Efficient Low-Rank Adaptation

Shiwei Li, Xiandi Luo, Haozhao Wang +6

Low-rank adaptation (LoRA) is a parameter-efficient fine-tuning (PEFT) method widely used in large language models (LLMs). LoRA essentially describes the projection of an input spa…
