High-Dimensional Approximation, Probability, and Statistical Learning
AS.110.675 (01)

The course covers fundamental mathematical ideas for certain approximation and statistical learning problems in high dimensions. We start with basic approximation theory in low-dimensions, in particular linear and nonlinear approximation by Fourier and wavelets in classical smoothness spaces, and discuss applications in imaging, inverse problems and PDE’s. We then introduce notions of complexity of function spaces, which will be important in statistical learning. We then move to basic problems in statistical learning, such as regression and density estimation. The interplay between randomness and approximation theory is introduced, as well as fundamental tools such as concentration inequalities, basic random matrix theory, and various estimators are constructed in detail, in particular multi scale estimators. At all times we consider the geometric aspects and interpretations, and will discuss concentration of measure phenomena, embedding of metric spaces, optimal transportation distances, and their applications to problems in machine learning such as manifold learning and dictionary learning for signal processing.

Nash-Moser iteration and Kolmogorov-Arnold-Moser (KAM) theory
AS.110.741 (01)

KAM theory is aiming at constructing invariant (under the flow of a dynamical system in finite or infinite dimensions) tori (as in invariant manifold) for Hamiltonian systems. I will start by reminders about symplectic geometry and topology. Then I will present an easy proof of the Siegel theorem in complex analysis using an easy version of the KAM scheme. Several lectures will be dedicated to “hard implicit function theorems” via Nash-Moser iterations in Frechet spaces. I will then state the KAM theorem in its original form and its modern variants and I will provide the three different proofs of Kolmogorov, Arnold and Moser in finite dimensions. Finally, I will explain the major difficulties in the case of Hamiltonian PDEs to adapt the previous proofs and will move on to some known results such as the ones of Kuksin, Poeschel, Bourgain and De La Llave and myself. I will probably explain in detail the results of Bourgain for nonlinear Schrodinger.

Topics in Stochastic Dynamical Systems
AS.110.757 (01)

The course will present an introduction to stochastic dynamical systems and some applications in model reduction and data assimilation. The main focus will be on stability and ergodicity of stochastic dynamical systems, including stochastic differential equations driven by white and fractional noise, and their numerical approximations. We will then discuss model reduction, focusing on Mori-Zwanzig formalism and approximation of the generalized Langevin equation, and methods on the parametric inference of related stochastic systems. Data assimilation and stochastic control will also be briefly introduced.
