Researchers have developed a novel machine learning method for creating subgrid-scale (SGS) parametrizations in coarse simulations of partial differential equations. This approach utilizes structure-preserving neural networks and entropy variables to learn subgrid fluxes for the Burgers' equation. The method employs a decoupled neural network architecture that separates subgrid corrections into a Flux Potential network and an Eddy Viscosity network, demonstrating high physical fidelity and robustness.
