New StableEdit method enhances lifelong model editing with normalization

Researchers have developed StableEdit, a new method for Lifelong Model Editing that addresses catastrophic forgetting and model collapse in large language models. The core innovation, Lifelong Normalization (LN), stabilizes value gradients using running statistics, which is crucial for maintaining performance over extended editing periods. Theoretical analysis reveals that LN, combined with ridge-regularized regression, creates a self-reinforcing stability loop that promotes parameter updates with asymptotic orthogonality and bounded norms, thereby mitigating forgetting and systemic collapse. StableEdit enhances this loop with a warm-up stage and full whitening, improving long-horizon stability with minimal overhead. AI

IMPACT Enhances the ability to continuously update LLMs with new information without degrading existing knowledge.
