Higher-Order FNO advances neural operators for nonlinear PDEs · 2 sources tracked

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced the Higher-Order Fourier Neural Operator (HO-FNO), an advancement on the Fourier Neural Operator (FNO) designed to better handle nonlinear partial differential equations (PDEs). HO-FNO incorporates an explicit n-linear mode mixing capability, which captures the structured interactions between modes characteristic of nonlinear PDEs. Experiments demonstrate that HO-FNO maintains FNO's efficiency while outperforming other spectral neural operators and competing with state-of-the-art transformers and state-space models, particularly in highly nonlinear scenarios like the Poisson equation.
