The process of aligning the separated features in the neurons to suit the purpose during Pretraining to optimize the task.
Unless there is no specific purpose or the memory is physically insufficient even with batch size 1, full parameter update is better than updating only some parameters through PEFT. However, if the spectrum of training data is limited, capabilities like conversational skills might be lost.
- Fine-tuning: update including embedding
- Feature-based: Fix embedding and update only the layer above.
