Some observations on high-dimensional partial differential equations with Barron data

2 Dec 2020  ·  Weinan E, Stephan Wojtowytsch ·

We use explicit representation formulas to show that solutions to certain partial differential equations lie in Barron spaces or multilayer spaces if the PDE data lie in such function spaces. Consequently, these solutions can be represented efficiently using artificial neural networks, even in high dimension. Conversely, we present examples in which the solution fails to lie in the function space associated to a neural network under consideration.
