trailRobust LLM unlearning requires selectively editing representations specific to forgotten data while preserving those shared with retained data.
The argument from the shared-representation root cause of shallow unlearning· for
Brief fine-tuning restores knowledge that standard LLM unlearning methods such as RMU and gradient ascent were applied to remove.
atomic
LLM unlearning is reversible and disruptive because methods alter representations shared with retained data and recoverable by fine-tuning.
atomic
The argument from non-editing routes to robust removal· against
Distilling an unlearned language model into a randomly initialized student makes unlearning robust to fine-tuning-based relearning.
atomic
Several 6.9B-parameter LLMs pretrained without biothreat text resist adversarial fine-tuning using up to 10,000 steps and 300M biothreat tokens.
