Abstract
Reproducing kernel Hilbert spaces (RKHS) provide an elegant framework for non-parametric learning of functions. A RKHS is uniquely determined by its reproducing kernel, which can be any symmetric positive semidefinite function on a given set of covariates. In this talk, I first review some basics about kernel-based learning, including the representer theorem, finite-sample guarantees, and low-rank approximations. I then discuss some recent applications in finance and statistics, including dynamic option pricing, term structure estimation, and estimation of Radon-Nikodym densities.
