We develop statistical tools for time series analysis of high-dimensional multivariate datasets, when a few core series are of principal interest and there are many potential ancillary predictive variables. Themethodology, based on Vector Autoregressions (VAR), handles the case where unrestricted fitting is precluded by the large number of serie...

Data assimilation is the process by which PDE-based models use measurements to produce an optimal representation of the state of the system. Different measurements bring different contributions to reducing uncertainty in the inference results. Quantifying the impact of observations is important for data pruning and for the configuration of senso...

In this talk, we connect the general problem of variational calculus tomoment problems and describe how this reformulation may be used to approach the original problem. Some recent developments on moment problems will be described.

Asymptotic variational methods are aimed at describing the overall properties of an increasingly complicated system by computing an effective limit energy where some parameters are averaged out or greatly simplified. Such methods include Gamma-convergence and variational expansions. An extremely interesting field of application is that of discre...

We consider variationally consistent discretization schemes for mechanical contact problems. Most of the results can also be applied to other variational inequalities such as those for phase transition problems in porous media, for plasticity or for option pricing applications from finance.The starting point is to weakly incorporate the constrai...

In this talk we will discuss a number of techniques to establish existence of smooth solutions of a class of mean-field games which have a variational structure.We start by showing that a number of mean-field games with local dependence on theplayer's density can be regarded as Euler-Lagrange equations for certainfunctionals. These functionals a...

In this course we develop the methodology of "variational modeling" of energy-driven systems. This methodology applies to systems whose evolution (in time) is driven by the decrease of an energy, in a friction-dominated or strongly damped way. Recent developments have shown that a surprisingly large class of evolutionary systems is of this form,...

According to Arnold's interpretation, the Euler equations forincompressible fluids can be seen as a geodesic equation in the space ofmeasure preserving diffeomorphism. Hence, one can look for solutions byminimizing the geodesic action functional with fixed endpoints. Since thisproblem is in general ill-posed, Brenier introduced at the end of the...

The alternating direction method of multipliers (ADMM) originated in the 1970s as a decomposition-coordination method for solving optimization problems. It has recently experienced a revival due to its highly distributed and parallel nature. It is typically applied when the objective function can be decomposed into a sum of functions over a set ...
