 It seems they successfully applied the Rank-1 editing technique from a <a href="https://arxiv.org/abs/2202.05262">memory editing paper for LLM</a>, with a few improvements. They also identified that the keys determine the "where" of the new concept, while the values determine the "what", and propose local / global-key locking to a superclass concept (while learning the values).
