CLaRE-ty Amid Chaos: Quantifying Representational Entanglement to Predict Ripple Effects in LLM Editing

arXiv:2603.19297v1 Announce Type: new Abstract: The static knowledge representations of large language models (LLMs) inevitably become outdated or incorrect over time. While model-editing techniques offer a promising solution by modifying a model's factual associations, they often produce unpredictable ripple effects, which are unintended behavioral changes that propagate even to the hidden space. In this work, we introduce CLaRE, a lightweight representation-level technique to identify where these ripple effects may occur. Unlike prior gradient-based methods, CLaRE quantifies entanglement between facts using forward activations from a single intermediate layer, avoiding costly backward passes. To enable systematic study, we prepare and analyse a corpus of 11,427 facts drawn from three existing datasets. Using CLaRE, we compute large-scale entanglement graphs of this corpus for multiple models, capturing how local edits propagate through representational space. These graphs enable str

To enable systematic study, we prepare and analyse a corpus of 11,427 facts drawn from three existing datasets. Using CLaRE, we compute large-scale entanglement graphs of this corpus for multiple models, capturing how local edits propagate through representational space. These graphs enable stronger preservation sets for model editing, audit trails, efficient red-teaming, and scalable post-edit evaluation. In comparison to baselines, CLaRE achieves an average of 62.2% improvement in Spearman correlation with ripple effects while being $2.74\times$ faster, and using $2.85\times$ less peak GPU memory. Besides, CLaRE requires only a fraction of the storage needed by the baselines to compute and preserve fact representations.

Executive Summary

This article presents a novel technique called CLaRE (CLaRE-ty Amid Chaos) for identifying potential ripple effects in large language model (LLM) editing. By quantifying representational entanglement using forward activations from a single intermediate layer, CLaRE outperforms baseline methods in terms of accuracy and computational efficiency. The authors demonstrate the effectiveness of CLaRE on a corpus of 11,427 facts drawn from three existing datasets, achieving a 62.2% improvement in Spearman correlation with ripple effects. CLaRE's entanglement graphs also enable stronger preservation sets, audit trails, and efficient red-teaming. This technique has significant implications for LLM editing, model auditing, and post-edit evaluation, making it a valuable contribution to the field of natural language processing.
