Bayesian PINNs achieve near-optimal rates for solving elliptic PDEs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for Bayesian Physics-Informed Neural Networks (PINNs) to solve elliptic partial differential equations. This approach offers statistical guarantees for uncertainty quantification by proving that the posterior distribution concentrates around the exact solution at a near-optimal rate. A key feature is the rate-adaptive prior, which achieves this optimal contraction without needing prior knowledge of the solution's smoothness. AI

IMPACT Provides theoretical guarantees for uncertainty quantification in solving differential equations with neural networks.

    Posterior Concentration of Bayesian Physics-Informed Neural Networks for Elliptic PDEs

    We study the posterior contraction rate of Bayesian Physics-Informed Neural Networks (PINNs) for solving a general class of elliptic partial differential equations (PDEs). We focus on learning of the elliptic equation with a non-homogeneous Dirichlet boundary condition from indep…
