Optimized Instance Alteration for Explaining and Assessing Robustness of Classifiers

arXiv:2607.06637v1 Announce Type: new Abstract: In this work, we propose a unified approach for diagnosing misclassification and assessing the robustness of black-box classifiers. Central to our method is an optimization framework that modifies an instance so that the classifier predicts a specified target label, while ensuring that the modification remains easily explainable. The objective function contains two components: an explainability-aware $L_0$ (XA-$L_0$) penalty that promotes sparse and interpretable modifications, and a classifier loss objective that steers the perturbed instance to

Why this matters
Why now

The increasing complexity and opacity of AI models necessitate robust methods for explainability and assessing their limitations, particularly as they are deployed in critical applications.

Why it’s important

This work introduces a unified framework to diagnose misclassification and gauge the robustness of black-box AI classifiers, directly addressing key concerns around AI trustworthiness and reliability.

What changes

The proposed optimization framework offers a concrete methodology for making AI model behavior more transparent and for quantifying their resilience to perturbed inputs.
