I live in, literally, the same home when I was swiping my first bank card and wondering if I'd have to put back the Charmin. We still don't have a dishwasher. My mom has done all these gardens so now my house looks like the garden shack in the middle of Versailles. — Rachael Ray 31 items · 3 sections

EvoUndo: Recoverability-Constrained Self-Evolution for LLM Agent Harnesses

Tanmay Sah, Dolly Sah, Harshul Jain, Tanya Sah

voUndo addresses the challenge of LLM agents self-modifying their systems, which can lead to irreversible changes. The framework enables the representation, synthesis, diagnosis, and verification of recoverability for these self-modifications across different states. EvoUndo significantly improves the ability to recover from failed mutations compared to conventional methods.

Unlearning pipeline. (1) The user files an unlearning request for a target content contained in the LLM. (2) We use GRACE, our proposed method, to find the best forget and retain coresets to remove the target content while preserving model utility. (3) These two sets are fed to a MU algorithm to perform unlearning.

GRACE:Gradient-guided Coreset Selection for LLM Unlearning

Praveen Bushipaka, Andrea D'Angelo et al.

GRACE addresses the challenge of unlearning unwanted knowledge from LLMs when only a few examples of undesired behavior are provided. Its core method is a gradient-guided coreset selection that constructs both forget and retain sets. GRACE first identifies a "…
