DGM and PINN Algorithms Proven to Converge to PDE Solutions

Researchers have mathematically proven that the Deep Galerkin Method (DGM) and Physics Informed Neural Networks (PINNs) can reliably converge to the correct solution for a specific class of semi-linear partial differential equations (PDEs). These methods, widely used in scientific machine learning, train neural networks to approximate PDE solutions by minimizing the PDE residual. While previously there was a theoretical concern about convergence to local minima due to the non-convexity of the objective function, this new work establishes that gradient descent will indeed lead to the accurate PDE solution for these types of equations.
