RRISE: Robust Radius Inference via a Surrogate Estimator
Researchers have developed RRISE, a novel framework for robust radius inference that significantly speeds up the process of certifying $\ell_2$ classification robustness. By training a learned surrogate model, RRISE replaces thousands of Monte Carlo sampling steps with a single forward pass, making certified robustness practical for real-time systems. This method achieves comparable certified accuracy to traditional randomized smoothing while drastically reducing computational cost during deployment. AI
