Regional Explanations: Bridging Local and Global Variable Importance

Researchers identify fundamental flaws in Local Shapley Values and LIME, two widely-used machine learning interpretation methods that fail to reliably detect locally important features. They propose R-LOCO, a new approach that bridges local and global explanations by segmenting input space into regions and applying global attribution methods within those regions for more faithful local attributions.

GradCFA: A Hybrid Gradient-Based Counterfactual and Feature Attribution Explanation Algorithm for Local Interpretation of Neural Networks

Researchers introduce GradCFA, a new hybrid AI explanation framework that combines counterfactual explanations and feature attribution to improve transparency in neural network decisions. The algorithm extends beyond binary classification to multi-class scenarios and demonstrates superior performance in generating feasible, plausible, and diverse explanations compared to existing methods.

A Polynomial-Time Axiomatic Alternative to SHAP for Feature Attribution

Researchers have developed ESENSC_rev2, a polynomial-time alternative to SHAP for AI feature attribution that offers similar accuracy with significantly improved computational efficiency. The method uses cooperative game theory and provides theoretical foundations through axiomatic characterization, making it suitable for high-dimensional explainability tasks.
