Test-Time Unlearning via Sparse Autoencoder

This work proposes ARIA (autoencoder-gated inference-time unlearning), a test-time unlearning method that leaves model weights intact and gates access to unwanted knowledge only when generation enters a forget-related state and introduces three post-unlearning adversarial attacks targeting weight-space and decoding-spa...

When Retain Constraints Conflict: Mitigating Forget-Retain Interference in Tabular Data

The results show that reliable tabular LLM unlearning depends not only on the forgetting objective, but also on how retain constraints are constructed, which shows that reliable tabular LLM unlearning depends not only on the forgetting objective, but also on how retain constraints are constructed.
