Can an AI Assistant Really Forget? Auditable Deletion from Addressable Memory

תקציר מקורי באנגליתarXiv:2607.27539v4 Announce Type: replace Abstract: An assistant can stop repeating a fact without removing it from memory. To study this difference, we install a support-vector gate in frozen Gemma 3 and record which stored keys and values belong to each exchange. A deletion request excludes the exchange's rows from the long-range readout and recalculates the gate on what remains. We check this operation against an independent refit, then compare it with running the model again on the conversation without the exchange. This second comparison matters because the exchange may already have influenced surviving memory rows. At 4B, the gated model passed checks for recall and feasible deletion on the same six of eight records admitted by the base model, at a perplexity cost under 2%. Admission
