Physics-Enhanced Machine Learning (with sampling)

I will present the recent work done by Felix Deitrich’s group in Munich. The talk will specifically focus on the SWIM method [1], a sampling algorithm that allows fast and accurate construction of neural network weights. I will cover the basic SWIM method and its recent developments: SWIM -PDE to solve partial differential equations [2] and SWIM -RNN to learn dynamical systems with a combination of neural networks and the Koopman operator.
