The paper introduces PRIME, a new variable‑importance measure that addresses two limitations of the existing proportional marginal effects (PME) method: it is applicable to stochastic models and reduces computational cost. PRIME achieves this by employing a model‑free variable‑selection technique to isolate active variables before computing importance. Experiments on synthetic test functions and real datasets demonstrate that PRIME accurately and reliably quantifies variable importance from noisy input‑output data.

arXiv:2604. 15107v2 Announce Type: replace-cross Abstract: Shapley values provide a flexible framework for attributing feature contributions to model predictions, but they are not naturally suited for feature selection: a feature may receive a positive attribution even when it is redundant given the remaining variables.
The paper introduces SHAP concentration as a pre‑deployment diagnostic for detecting when conformal prediction will fail under distribution shift, specifically in gradient‑boosted classifiers. Using a COVID‑19 supply‑chain case study, the authors show that higher feature‑importance concentration correlates with larger drops in coverage, while standard shift detectors cannot differentiate between catastrophic and robust outcomes. The diagnostic is validated on additional datasets, and a formal theorem links concentration to worsening conformity‑score bounds, though it does not capture global‑sensitivity failures in neural networks.
