New neural operators enhance PDE solving with Shearlet and LNF-NO architectures

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 3 sources

Two new research papers introduce novel neural operator architectures designed to improve the efficiency and accuracy of solving partial differential equations (PDEs). The first, Linear-Nonlinear Fusion Neural Operator (LNF-NO), decouples linear and nonlinear effects for faster training and better interpretability. The second, Shearlet Neural Operator (SNO), replaces Fourier transforms with shearlets to better handle anisotropic structures and sharp gradients common in shock-dominated and multi-scale problems.
