New multi-dimensional Kolmogorov-Smirnov distance formulation proposed

Researchers have developed a new formulation for the multi-dimensional Kolmogorov-Smirnov (KS) distance, an integral probability metric that measures the difference between probability distributions. This novel approach maximizes differences over orthogonal dominating rectangular ranges and provides theoretical guarantees for its convergence and approximation error. The method allows for efficient computation of the distance in up to four dimensions, enabling a delta-precision two-sample hypothesis test. AI

IMPACT This research could lead to more robust statistical methods for evaluating generative models and AI systems.
