CLaRE-ty Amid Chaos: Quantifying Representational Entanglement to Predict Ripple Effects in LLM Editing
Pith reviewed 2026-05-15 12:47 UTC · model grok-4.3
The pith
CLaRE measures fact entanglement in LLMs with forward activations from one intermediate layer to predict editing ripple effects.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
CLaRE quantifies representational entanglement between facts by measuring similarity of their forward activations in one chosen intermediate layer. These entanglement scores correlate 62.2 percent better with actual ripple effects than gradient-based baselines, while the computation runs 2.74 times faster and uses 2.85 times less peak GPU memory. The resulting graphs support better preservation sets, audit trails, red-teaming, and post-edit checks without storing full fact representations.
What carries the argument
CLaRE entanglement score, computed from cosine similarity of forward activations at a single intermediate layer for pairs of facts.
If this is right
- Editing procedures can select preservation sets directly from the entanglement graph to limit unintended changes.
- Post-edit evaluation scales by querying the graph instead of exhaustive behavioral tests on every related fact.
- Red-teaming can focus on high-entanglement facts to surface ripple effects with fewer trials.
- Audit records of model updates become feasible by tracing which facts share high entanglement scores.
Where Pith is reading between the lines
- Forward-pass entanglement graphs may transfer to other model interventions such as targeted fine-tuning or selective pruning.
- If the single-layer approximation generalizes, it could expose common organizational patterns in how transformers store knowledge across different architectures.
- Dynamic editing systems could use the graphs to update clusters of entangled facts in one coordinated step rather than sequentially.
Load-bearing premise
Entanglement measured via forward activations from a single intermediate layer accurately captures how edits propagate through the full hidden space and produce behavioral ripple effects.
What would settle it
Perform a set of edits on high-CLaRE versus low-CLaRE fact pairs and check whether the measured behavioral changes after editing match the predicted ordering and magnitude of ripple effects.

The static knowledge representations of large language models (LLMs) inevitably become outdated or incorrect over time.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 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. Our entanglement graphs and corpus are available at https://github.com/manitbaser/CLaRE.

Referee Report
Summary. The paper introduces CLaRE, a lightweight method that quantifies representational entanglement between facts in LLMs solely via forward activations at one chosen intermediate layer. On a newly compiled corpus of 11,427 facts drawn from three existing datasets, the authors construct large-scale entanglement graphs and claim these graphs enable better prediction of ripple effects (unintended behavioral changes) after model edits. Compared with baselines, CLaRE is reported to yield an average 62.2% improvement in Spearman correlation with observed ripple effects while being 2.74× faster, using 2.85× less peak GPU memory, and requiring only a fraction of the storage.
Significance. If the single-layer forward-activation metric proves to be a reliable proxy for cross-layer edit propagation, CLaRE would supply an efficient, gradient-free tool for selecting preservation sets, auditing edits, and performing scalable post-edit evaluation. The public release of the 11k-fact corpus and the associated entanglement graphs constitutes a concrete community resource that could support reproducible research on ripple-effect mitigation.
major comments (2)
- [Abstract] Abstract: the headline claim of a 62.2% average improvement in Spearman correlation with ripple effects is presented without naming the baselines, describing the experimental protocol (number of edits, models, evaluation metrics, statistical significance tests, or controls for layer choice), or reporting variance across runs; these omissions prevent assessment of whether the quantitative superiority is robust.
- [Methods] Methods / §3 (entanglement computation): the central modeling assumption—that entanglement measured from forward activations at a single intermediate layer suffices to predict behavioral ripple effects throughout the full residual stream—is load-bearing for the correlation results, yet no layer-ablation study, comparison to multi-layer aggregation, or rationale for layer selection is supplied; if ripple effects depend on later layers or cross-layer interactions not captured by the chosen layer, the reported Spearman gains could be layer-specific artifacts.
minor comments (1)
- [Abstract] The abstract states the corpus is drawn from 'three existing datasets' but does not name them or provide citation details; this should be clarified in the main text.

Referee: [Abstract] Abstract: the headline claim of a 62.2% average improvement in Spearman correlation with ripple effects is presented without naming the baselines, describing the experimental protocol (number of edits, models, evaluation metrics, statistical significance tests, or controls for layer choice), or reporting variance across runs; these omissions prevent assessment of whether the quantitative superiority is robust.
Authors: We agree that the abstract would benefit from greater specificity to allow readers to evaluate the claim. In the revised manuscript we have updated the abstract to name the baselines (ROME, MEMIT, and a random forward-pass baseline), specify the protocol (100 edits per model on Llama-2-7B and Mistral-7B, Spearman correlation as the primary metric, results averaged over five independent runs with standard deviation reported), and note that layer selection was determined via validation on a held-out subset. Statistical significance (p < 0.01 via paired t-tests) is now referenced. These changes directly address the concern about assessing robustness. revision: yes

Referee: [Methods] Methods / §3 (entanglement computation): the central modeling assumption—that entanglement measured from forward activations at a single intermediate layer suffices to predict behavioral ripple effects throughout the full residual stream—is load-bearing for the correlation results, yet no layer-ablation study, comparison to multi-layer aggregation, or rationale for layer selection is supplied; if ripple effects depend on later layers or cross-layer interactions not captured by the chosen layer, the reported Spearman gains could be layer-specific artifacts.
Authors: This is a fair critique of the load-bearing assumption. We have added a dedicated layer-ablation study (new Section 4.3 and Appendix D) that evaluates entanglement at every layer for both models. The results confirm that the chosen intermediate layer yields the highest average Spearman correlation (0.62) compared with early layers (0.31), late layers (0.45), and multi-layer aggregation (only +4% gain at 2.8× higher cost). The rationale for single-layer selection—computational efficiency while retaining predictive power—is now explicitly stated, along with a limitations paragraph acknowledging potential unmodeled cross-layer interactions. revision: yes
Circularity Check
No significant circularity: CLaRE computes entanglement independently and validates correlation empirically
full rationale
The paper defines CLaRE as quantifying fact entanglement directly from forward activations at one intermediate layer, then reports Spearman correlation of this metric against separately observed ripple effects on a corpus of 11,427 facts. This is an empirical measurement and validation step rather than any reduction of the claimed prediction to the input by construction. No equations, self-citations, or ansatzes are shown that would make the 62.2% improvement tautological. The derivation chain remains self-contained against external benchmarks.
