Learning Physical Laws from Data

By Prof. Sven Wang (HU Berlin)

Date: January 21, 2025

Speaker Introduction

Prof. Sven Wang is an assistant professor for Mathematical Statistics and Stochastics at the Humboldt University of Berlin. He previously studied mathematics at LMU Munich and Cambridge University and holds a PhD in Mathematical Statistics from Cambridge University. Before he started his position as an assistant professor here in Berlin, he spent two years as a Postdoc at the Massachusetts Institute of Technology (MIT).

Abstract

Many data collection processes in natural scientific settings are described by partial differential equations (PDEs) and stochastic differential equations (SDEs). In these settings, key statistical tasks such as the estimation of unknown high-dimensional parameters, prediction and uncertainty quantification have given rise to sophisticated frequentist and Bayesian statistical methodology. Recently, 'Scientific Machine Learning' has also played a big role in inferring complex relationships from data. In this talk, we discuss recent mathematical results in this broad context. In particular, we discuss dimension-free statistical convergence results for regression of 'operators' with neural networks, and we discuss the computational complexity of sampling from high-dimensional posterior distributions. If time permits, we will also discuss some mathematical foundations for PDE and SDE-based generative AI models.

This presentation focuses on a novel approach called OKO (odd-k-out learning), which aims to enhance the accuracy and calibration of machine learning models. OKO is a user-friendly method that improves model performance by modifying how data points are sampled during training and adjusting the computation of cross-entropy. This principled set learning approach is designed to help machine learning models provide predictions that are not only accurate but also well-balanced and reliable.
