arXiv:2606.16941v1 Announce Type: cross Abstract: Detecting distributional differences between two independent samples is a fundamental problem in statistics and machine learning. Nonparametric two-sample testing provides a principled framework for determining whether two samples are drawn from the same underlying distribution, without assuming any specific parametric form for the distribution. In this study, we propose a new two-sample test statistic based on a newly introduced integral probability metric (IPM), using a specially designed parametric discriminator class with a single node of a
This research is part of ongoing efforts in machine learning and statistics to develop more robust and efficient methods for comparing data distributions, a fundamental problem in various AI applications.
Improved two-sample tests are crucial for evaluating generative models, anomaly detection, and ensuring fairness and bias detection in AI systems, impacting their reliability and deployment.
This new nonparametric test offers a potentially more powerful and flexible method for detecting distributional differences, enhancing the statistical rigor of machine learning evaluations.
