## Colloquium Mathematical Physics

Topic:

### Random matrices, spin glasses, and machine learning

Date:

23.07.21

Time:

16:15

Place:

ZOOM/Konferenzschaltung

Guest:

Jon Keating

Oxford University

Abstract:

I will describe some problems relating to machine learning and their connections to random matrix theory and spin glasses. These connections give a mathematical framework for understanding in qualitative terms the effectiveness of certain algorithms that are important in machine learning, but developing them into precise models remains a major challenge. I will reflect on the different roles played by models in computer science and physics, focussing on those involving random matrices.

## Seminar High Energy Physics

Topic:

### Machine Learning for Thermodynamic Observables in Lattice Field Theories

Date:

06.07.21

Time:

14:15

Place:

Online, via ZOOM

Guest:

Lena Funcke

Abstract:

In this talk, I will discuss how applying machine learning techniques to lattice field theory is a promising route for solving problems where Markov Chain Monte Carlo (MCMC) methods are problematic. More specifically, I will show that deep generative models can be used to estimate thermodynamic observables like the free energy, which contrasts with existing MCMC-based methods that are limited to only estimate free energy differences. I will demonstrate the effectiveness of the proposed method for two-dimensional $\phi^4$ theory and compare it to MCMC-based methods in detailed numerical experiments.
