Fine-Tuning

The process of taking a pre-trained model and continuing to train it on a smaller, specific dataset to adapt it for a particular task or domain.

Definition

The process of taking a pre-trained model and continuing to train it on a smaller, specific dataset to adapt it for a particular task or domain. Much cheaper and faster than training from scratch. LoRA and QLoRA are popular efficient fine-tuning methods that only update a small fraction of parameters.
