Researchers have introduced $\alpha$-TCAV, a new framework designed to improve the statistical stability and practical utility of Concept Activation Vectors (CAVs) in deep learning explainability. The proposed method addresses a fundamental flaw in the standard TCAV score, which can lead to unstable results, by replacing a discontinuous function with a smooth, parameterized one. This generalization unifies existing TCAV variants and offers principled guidance for tuning parameters, potentially leading to more reliable concept influence measurements at a lower computational cost.
