New methods combine Monte Carlo and neural networks for solving boundary value problems

This paper explores novel methods for approximating solutions to Poisson's equation, a fundamental problem in mathematical physics. Researchers demonstrate that Monte Carlo methods, particularly an accelerated walk on spheres algorithm, can efficiently provide numerical approximations for the equation's solutions. Furthermore, the study shows how these Monte Carlo solvers can be used to construct deep neural networks (DNNs) that also approximate the solutions, with the size of these networks depending polynomially on the problem's dimension and desired accuracy.
