Why AI Forgets: Digital Amnesia, PEFT, LoRA & Smarter Fine-Tuning Strategies
Large Language Models suffer from “catastrophic forgetting” when fine-tuned, a phenomenon the author calls digital amnesia. The article explains the underlying mechanics (gradient conflict, representational drift) and the danger of loss landscape flattening. It advocates for Parameter-Efficient Fine-Tuning (PEFT) techniques like LoRA and QLoRA to specialize LLMs efficiently while preserving their core knowledge and preventing data loss.
