What is Weak PINNs for Entropy Solutions about?

The document introduces weak Physics Informed Neural Networks (wPINNs) as a novel approach to accurately approximate entropy solutions of hyperbolic conservation laws, which are often discontinuous. It highlights the limitations of traditional Physics Informed Neural Networks (PINNs) in handling such cases and presents a min-max optimization framework to improve approximation accuracy. The authors prove rigorous error bounds for wPINNs and demonstrate their effectiveness through numerical experiments.
