IFML Seminar: 02/13/26 - COWS and Their Hybrids: Customized Orthogonal Weights

IFML Seminar: 02/13/26 - COWS and Their Hybrids: Customized Orthogonal Weights Abstract: Particle physicists developed an algorithm called COWs (Customized Orthogonal Weights) for separating signals from backgrounds in certain experiments. We look at COWs from a statistical perspective. Then we consider several extensions of the method. In particular, a modified version of the method leads to a robust method for estimating arbitrary mixtures of conditionally independent distributions. This is joint work with Chad Schafer and Mikael Kuusela. Bio: Larry Wasserman is University UPMC Professor of Statistics and Data Science at Carnegie Mellon University. He is also Professor in the Machine Learning Department. He is a member of STAMPS (STAtistical Methods for the Physical Sciences).
