Assessing Alignment and Stability of Feature Importance Explanations via Weight of Evidence

Read the original on arXiv AI →

The paper introduces a hypothesis‑testing framework that embeds feature importance methods (FIMs) within a Weight of Evidence (WoE) analysis. By quantifying how strongly observed evidence supports a given hypothesis—whether from domain knowledge, ground truth, or the FIM itself—the approach evaluates FIM alignment and variability. The authors provide theoretical links between WoE and attribution variance and demonstrate the method on LIME and SHAP explanations across varied reference hypotheses.

Faithfulness Without Anchors: A Position Paper on the Structural Misalignments of Explainable AI Faithfulness Metrics for Feature Importance

The paper argues that explainable AI (XAI) tools, intended to increase trust in machine learning models, often fail to do so and instead foster overreliance on incorrect predictions. It attributes this failure to the unfaithfulness of XAI methods, which oversimplify model internals and misalign explanations with the actual model behavior. The authors identify five major shortcomings in current faithfulness metrics and propose four research directions to improve their reliability.

Evaluating Explanation Methods by the Predictors They Induce

The paper proposes a new evaluation test for explanation methods: if an explanation accurately captures how a model uses its features, one should be able to reconstruct the model’s predictions from it. The authors convert explanations into predictors by summing feature effects and assess how well these predictors reproduce the model on unseen data, without any fitting. They apply this test to partial dependence plots, accumulated local effects, SHAP, and LIME across multiple datasets and model families, showing that the best method depends on feature dependence and that some existing quality metrics can favor flawed explanations.

Beyond feature attribution: Recovering latent interaction structures in machine learning models via localized CBFI

The paper introduces localized case-based feature importance (CBFI), a framework that decomposes individual predictions in complex tabular models into distinct structural components, separating independent main effects from pure interactions. Unlike additive explanations such as SHAP and LIME, CBFI explicitly captures feature synergies, enabling the recovery of latent interaction structures. Experiments on wine quality classification and medical insurance regression, along with fidelity tests and synthetic benchmarks, show that CBFI accurately disentangles interactions hidden by additive models and aligns with the nonlinear dependencies in gradient boosting and deep neural networks.
