New FNO method uses lattice points for improved efficiency

Researchers have developed a new approach to Fourier Neural Operators (FNOs) that improves their efficiency and accuracy. By replacing standard tensor product grids with rank-1 lattice points and using a hyperbolic cross frequency index set, the method requires fewer parameters and training samples. This lattice-based hyperbolic-cross FNO architecture simplifies the high-dimensional Fourier transform into a single one-dimensional fast Fourier transform, demonstrating benefits for solving partial differential equations.
