Researchers have introduced the Local Gradient Neural Operator (LGNO), a novel deep learning approach for predicting field temporal evolution and identifying sources in dynamical systems. Unlike existing global neural operators that often require extensive data and parameters, LGNO is designed to be lightweight and interpretable. It leverages principles of nonlinear gradient discretization and employs multilayer perceptron convolutional layers to learn translation-invariant local kernels, which function similarly to discrete stencils. This method has demonstrated accuracy, parameter efficiency, and stability across various PDE benchmarks, including linear and nonlinear cases, and shows broad applicability to mechanical problems.
