LoRA

Low-Rank Adaptation.

Definition

Low-Rank Adaptation. An efficient fine-tuning method that freezes the original model weights and only trains small adapter matrices. Drastically reduces the compute and memory needed for fine-tuning — you can customize a 70B model on a single GPU. QLoRA adds quantization for even more savings.
