WLNO: Wavelet-Laplace Neural Operator for Solving Partial Differential Equations
Researchers have introduced the Wavelet-Laplace Neural Operator (WLNO), a new neural operator designed to solve partial differential equations. WLNO enhances the existing Laplace Neural Operator (LNO) by incorporating a Haar wavelet transform to decompose and analyze spatial features across multiple scales. This fusion allows WLNO to better capture localized multi-scale characteristics inherent in complex PDE solutions, leading to improved performance over LNO on benchmark problems like the Burgers and Navier-Stokes equations.
