Workshop IV: Using Physical Insights for Machine Learning
18 nov 2019 - 22 nov 2019 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure and Applied Mathematics (IPAM), UCLA
Résumé:
Part of the Long Program Machine Learning for Physics and the Physics of Learning.

In this workshop we will explore how to use physical intuition and ideas to design new classes of machine learning (ML) algorithms. Physics-inspired sampling algorithms could be used to train ML structures or sample the hyper-parameter space (e.g. deep Neural Networks). Additionally, physics-based models such as Ising/Potts models or energy-based models have influenced ML inference frameworks such as Markov Random Fields and Restricted Boltzmann Machines, and we want to continue the discussion to facilitate this innovation transfer. Finally, physical insight could be used to enhance learning in the situation of scarce data by enforcing smoothness, differentiability or other physical properties relevant to a given problem.

Long Program — High Dimensional Hamilton-Jacobi PDEs
09 mar 2020 - 12 jui 2020 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure and Applied Mathematics (IPAM), UCLA
Résumé:
Applications that involve HJ PDEs in a high-dimensional (and possibly infinite-dimensional) setting lead to challenging computational problems. Although a large literature is available on HJ PDEs, many challenges remain both from a mathematical and computational point of view. The program will open with one week of tutorials, presented by some of the main organizers. These tutorials will provide an introduction to the major themes of the entire program and connect the themes of the four workshops. The goal is to introduce a common language and build a foundation for the participants of this program who have diverse scientific backgrounds. During the weeks between workshops, participants in residence will develop collaborations; we expect fruitful discussions especially between domain scientists, algorithm developers and pure and applied mathematicians.

High Dimensional Hamilton-Jacobi PDEs — Workshop I: High Dimensional Hamilton-Jacobi Methods in Control and Differential Games
30 mar 2020 - 03 avr 2020 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure and Applied Mathematics (IPAM), UCLA
Résumé:
Ideas to be explored in the workshop include different computational methodologies for efficient real-time solution of nonlinear HJ equations in reachability, optimal control, and differential games. Ideas such as efficient reduced-complexity computation of optimal control solutions, exploiting structure to decompose the solution space to scalable computations and reduced-complexity feedback structures for efficient implementation of optimal controllers based on available data will be considered.

High Dimensional Hamilton-Jacobi PDEs — Workshop III: Mean Field Games and Applications
04 mai 2020 - 08 mai 2020 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure and Applied Mathematics (IPAM), UCLA
Résumé:
This week-long workshop on Mean Field Games (MFG) and Applications for has a number of goals: (i) to gather together leading researchers in MFG and certain cognate areas (economics, optimal transportation, finite dimensional Hamilton-Jacobi equations, Stochastic equations, applied control, numerics). (ii) to expose new researchers to the promise of the field and its array of challenges, while grounding them in its basic techniques; (iv) to make available to the wider community a series of broad interest talks on MFG.

High Dimensional Hamilton-Jacobi PDEs — Workshop IV: Stochastic Analysis Related to Hamilton-Jacobi PDEs
18 mai 2020 - 22 mai 2020 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure and Applied Mathematics (IPAM), UCLA
Résumé:
In spite of its flexibility, computing nonlinear problems in random media is very expensive. Hence, in practice, it is needed to consider environments which are small random perturbations of periodic ones, and then to obtain some asymptotic expansion for the ergodic constants. Concrete examples of such phenomena that relate to Hamilton-Jacobi equations are large deviations, front propagation and random walks in random media. The latter strengthens the connection with probability.

Graduate Summer School: Mathematics of Topological Phases of Matter
22 jui 2020 - 26 jui 2020 • Los Angeles, CA, États-Unis
Résumé:
The application of topology to physics has become an integral part of a second quantum revolution in the sciences. The discovery of topological insulators and progress towards topological superconductors realizing non-abelian statistics has moved topological phases of matter onto the center stage in the interaction of topology and physics beyond the quantum Hall effect. While topological physics has been intensively investigated by physicists for the last few decades, the mathematical theory lags far behind. One challenge is formulating the right definition of topological phases of matter, which is closely related to the notoriously difficult problem of finding a rigorous mathematical formulation of quantum field theory. In this summer school, we will focus on two relatively mature foundational topics, and two new directions in the mathematics of topological phases of matter.
