Workshop on Mathematical Machine Learning and Application

The Workshop on Mathematical Machine Learning and Application will take place on April 27-29, 2020. Workshop will be held in room 114 of the Department of Mathematics of Penn State, located at McAllister Building, Pollock Rd, State College, PA.
As part of the workshop, Prof. George Karniadakis and Prof. Jinchao Xu will deliver introductory lectures on the mathematics of deep learning with junior participants as the target audiences on Sunday, April 26 2020.


Today, machine learning is a hot topic with important practical applications. Notable successes are the classification problems for identifying pictures and the Artificial Intelligence (AI) Go-player, AlphaGo Zero, which beat the best human player in the world. While these successes indicate that we are making progress toward applying AI to various important tasks, there are many emerging scientific questions. For instance, how can we understand these empirical successes in a mathematically rigorous way, using approximation theory and probability theory? Can we develop a theory which can guarantee the success of machine learning models in certain situations? How can we apply ideas from machine learning to existing problems in numerical analysis, such as Bayesian inference, operator estimation, solving PDE’s, density estimation, sampling methodology, and uncertainty quantification. Can machine learning be applied to the mathematical modeling of dynamical systems that historically relies on first principle calculations?

This workshop aims to bring together leading experts across scientific disciplines to discuss recent efforts in addressing these questions. Our hope is that the activity will inspire and attract participants to work on related mathematical problems in this emerging field and hopefully contribute to the development of the modern data-driven scientific computational methods to address these questions.
