arXiv:2606.08871v1 Announce Type: cross Abstract: The \emph{Fourier neural operator} (FNO) is a neural network architecture that learns mappings between function spaces. Its efficient implementation is based on the multi-dimensional Fourier transform. By deriving general regularity bounds for the FNO with respect to both the spatial and parametric variables, we prove that the generalization error of the FNO can be improved by replacing spatial tensor product grids with purpose-built rank-1 lattice points, and by using a second lattice carefully constructed as training points in the parametric
The continuous drive for more efficient and generalizable AI models necessitates fundamental research into architectural improvements.
Improved FNO efficiency and generalization could lead to more robust and powerful AI solutions applicable across various scientific and engineering domains.
This research proposes methods to enhance FNOs by optimizing spatial and parametric training points, potentially lowering computational costs and improving accuracy for complex function-space mappings.
