We consider the recovery of signal via compressive sensing where the signalitself or its gradient are assumed to be sparse. This amounts to solvea l1 or a Total Variation minimization problem. We propose minimization algorithms specifically designed to take advantageof shared memory, vectorized, parallel and manycore microprocessors such asthe C...

The game of football is undergoing a significant shift towards the quantitative. Much of the progress made in the analytics space can be attributed to play-by-play data and charting data. However, recent years have given rise to tracking data, which has opened the door for innovation that was not possible before. In this talk I will describe ho...

An intriguing fact about the celebrated Nash equilibrium concept infinitegames is that it can be expressed mathematically in a variety of ways:as a fixed point, a solution to a complementarity program, a (global)minimizer, or a solution to a system of polynomial equations andinequalities.As a result, there are general-purpose algorithms to compu...

There is emerging interest in using soft materials for energy conversion, particularly in the conversion of light and heat energy into mechanical work. Liquid crystals, where the coupling of orientational order and strain/stress may be employed for this purpose, are promising materials for such applications. The celebrated work of Onsager [1] on...

The theory of finite element exterior calculus has enabled thearrangement of a wide selection of well-known finite elements into asystematic table: the periodic table of finite elements. Much like theperiodic table of chemical elements which clarifies and explains theproperties of the chemical elements based on their electron structure,the perio...

Low dimensional elastic manifolds (such as rods 1D or sheets2D) have been drawing a lot of attention lately. When confined intoenvironments smaller than their size at rest, elastic objects sustainlarge deformations involving many fascinating mechanisms such as energycondensation from large length-scales to small singular structures,topological s...

We describe a topos of sheaves with the property that classical persistent homology of a filtered complex (should) be the internal simplicial homology functor of the logic specified by the base space of the sheaves. All relevant background to understand definitions and their ramifications will be provided in the talk.

Within only a decade since the first draft of the human genome, we've witness astonishing pace of development of technologies for high throughput molecular profiling that probe various aspects of genome biology and its relationship to tumorigenesis and cancer treatment. There have been giant steps towards cataloging massive amounts of data and p...

We will report on our experiences implementing PDE solvers on Peta-Scale computers, such as the 290 000 core IBM Blue Gene system in the Jülich Supercomputing Center. The talk will have two parts, the first one reporting on our Hierarchical Hybrid Grid method, a prototype Finite Element Multigrid Solver scaling up to a trillion (10^12) degrees ...
The field of fairness in machine learning has yet to settle on definitions. At a high level, there are (at least) two approaches: individual, and statistical definitions of fairness. Statistical definitions of fairness ask that some statistic of the classifier (like error rate or false positive rate) be equalized across some set of groups. While...

Predictive modeling of physical processes in heterogeneous media requires innovations in mathematical and computational thinking. While multiscale approaches have been successful in modeling the effects of fine scales to macroscopic response, a significant grant challenge remains in understanding the effects of topological uncertainties in chara...
