ProToMEx: Rapid, Interpretable Explanations via Structured Representations

ProToMEx is a new explainability framework that uses Probabilistic Topic Models to learn latent topics representing high‑level reasons behind a classifier’s decisions, moving beyond simple feature attribution. It provides both global and local explanations, revealing multiple co‑existing reasons for individual predictions. Empirical results show that ProToMEx achieves comparable fidelity to SHAP and LIME while being 30–40× faster on standard tabular and synthetic datasets.

Distributionally Robust Regularization of Sparse Integer Programming Trained Learning Models

The paper proposes a distributionally robust regularization technique for mixed‑integer sparse programming models used in explainable machine learning. It extends recent DRO advances, traditionally applied to convex formulations, to mixed‑integer settings, offering statistical guarantees linked to a sparsity parameter. The method is demonstrated on binary classification models built from feature‑value rule sets.
