Currently teaching

Numerical Methods for Data Science (CS 6241)

Hollister 320. TR 2:55-4:10.

Discussion of numerical methods in the context of machine learning and data analysis problems. We will discuss sparsity, rank structure, and spectral behavior of underlying linear algebra problems; convergence behavior and implicit regularization for standard solvers; and comparisons between numerical methods in data analysis and those used in physical simulations.

SCAN Seminar (CS/MATH 7290)

    Ongoing. M 1:30-2:20.

    The Scientific Computing and Numerics seminar series focuses on various methods in scientific computing, the analysis of convergence properties and computational efficiency, and their adaptation to specific applications.
