Does your LLM truly unlearn? An embarrassingly simple approach to recover unlearned knowledge
Summary
This research paper investigates a critical flaw in current machine unlearning methods for large language models (LLMs). The authors discover that applying quantization, a process used to compress and optimize LLMs for resource-constrained environments, can inadvertently restore "forgotten" knowledge. The paper provides a theoretical explanation for this phenomenon and proposes a new unlearning strategy, "Saliency-Based Unlearning with a Large Learning Rate (SURE)," to mitigate this issue and ensure genuine unlearning without compromising model utility. The study underscores the need for more comprehensive and robust approaches to machine unlearning in LLMs, highlighting a critical oversight in existing unlearning benchmarks.
