Project

Discrepency measures ar eindicators that quantify the irregularity of a finite set of points P, taken from the hypercube [0,1]^d. Low discrepancy point sets are used in numerical integration, for the design of experiments, for initial sampling in Bayesian Optimization algorithms, for hyperparameter optimization, in computer vision, and many more. The scientific goal of this project is to advance the theoretical understanding and the algorithmic computation of low discrepancy point sets by combining state-of-the-art methods from Computer Science and from Mathematical Optimization for mutual benefit. Simultaneously, we establish an international and cross-disciplinary collaboration between working groups from Sorbonne University and the University of Wuppertal.
