Researchers have developed a new theoretical framework to rigorously certify the error bounds of neural partial differential equation (PDE) solvers. This work addresses the challenge of quantifying uncertainty in neural networks used for PDEs, which differs from traditional methods relying on mesh refinement. The new approach establishes generalization bounds that link the control of residual errors to the accuracy of the solution in the solution space. It proves that minimizing residual errors leads to convergence towards the true solution when neural approximations are within a compact subset of the solution space, providing both deterministic and probabilistic convergence results.
