Model-free Subsampling Method Based on Uniform Designs

no code implementations8 Sep 2022 Mei Zhang, Yongdao Zhou, Zheng Zhou, Aijun Zhang

In order to measure the goodness of representation of a subdata with respect to the original data, we propose a criterion, generalized empirical F-discrepancy (GEFD), and study its theoretical properties in connection with the classical generalized L2-discrepancy in the theory of uniform designs.
