Computational and Applied Mathematics Seminar: Ke Chen, Maryland, Towards efficient deep operator learning for forward and inverse PDEs: theory and algorithms

October 27, 2023 | 12:45 pm - 1:45 pm EDT

Deep neural networks (DNNs) have been a successful model across diverse machine learning tasks, increasingly capturing the interest for their potential in engineering problems where PDEs have long been the dominant model. This talk delves into efficient training for PDE operator learning in both the forward and the inverse problems setting. Firstly, we address the curse of dimensionality in PDE operator learning, demonstrating that certain PDE structures require fewer training samples through an analysis of learning error estimates. Secondly, we introduce an innovative DNN, the pseudo-differential auto-encoder integral network (pd-IAE net), designed for solving multiple inverse problems.
