Inference-Time Machine Unlearning via Gated Activation Redirection

arXiv cs.LG · 2026-05-14 Cached

This paper introduces GUARD-IT, a training-free method for machine unlearning that uses input-dependent activation steering at inference time to remove targeted knowledge from LLMs without modifying weights, matching or exceeding gradient-based baselines while preserving utility and robustness to quantization.
