Overview

Randomized trial investigates stability of XAI methods under prediction-preserving perturbations, highlighting resilience variations.

Key Points

  • This research aims to explore the stability of various explainable AI methods under conditions where predictions remain unchanged despite perturbations.
  • Applied four post hoc explanation methods: Integrated Gradients, SHAP, Vanilla Gradients, and Grad-CAM.
  • Conducted experiments with a controlled perturbation magnitude of 0.01 maintaining consistent predicted classes.
  • Used a cosine-based similarity measure to evaluate the divergence of explanation maps across different methods.
  • SHAP showed significant variance in explanations (mean = 0.6475), while Grad-CAM demonstrated very low variance (mean = 0.0058).
  • Vanilla Gradients and Integrated Gradients recorded moderate variance (means = 0.4647 and 0.3319, respectively).
  • The findings suggest that explanation divergence starts before prediction changes, marking explanations as sensitive indicators of model vulnerability.
