Researchers have introduced Perturbative-NeuSA, a novel framework designed to improve the accuracy and efficiency of neural spectral solvers for time-dependent partial differential equations (PDEs). This method decomposes the solution into a low-fidelity background and a high-resolution perturbation, allowing the neural network to learn only the unresolved dynamics. Experiments on various equations, including 2D Burgers and wave equations, demonstrated that the structured solver outperforms traditional neural network baselines without requiring training, significantly reducing errors and offering insights into the conditional nature of neural closures.
