Title:  Concentration and Conditioning of Random Feature Matrices

Abstract:   Being able to write down a mathematical model, i.e. a system of governing equations, for complex physical systems is a fundamental problem in science and engineering and is seeing assistance and automation from the machine learning perspective. As data-driven scientific discovery increases in popularity so does the need for rigorous algorithmic and theoretical work. In this talk, I will discuss a sparse random feature method with applications to learning equations from data. I will provide an overview of our theoretical results on the concentration of these random feature matrices, the connections to generalization and complexity bounds, and the design and applications of the method. Examples and applications to high-dimensional modeling and dynamics will be included.
