Post-training for large language models (LLMs) is constrained by the high
cost of acquiring new knowledge or correcting errors and by the unintended side
effects that frequently arise from retraining. To address these issues, we
introduce REPAIR (Robust Editing via Progressive Adaptive Intervention and
Reintegration), a lifelong editing framework designed to support precise and
low-cost model updates while preserving non-target knowledge. REPAIR mitigates
the instability and conflicts of large-scale sequential edits through a
closed-loop feedback mechanism coupled with dynamic memory management.
Furthermore, by incorporating frequent knowledge fusion and enforcing strong
locality guards, REPAIR effectively addresses the shortcomings of traditional
distribution-agnostic approaches that often overlook unintended ripple effects.
Our experiments demonstrate that REPAIR boosts editing accuracy by 10%-30%
across multiple model families and significantly reduces knowledge forgetting.
This work introduces a robust framework for developing reliable, scalable, and
continually evolving LLMs.
