Multiscale Fourier Neural Operator for Inverse Wave Scattering in Highly Oscillatory Media
Zilin You, Zhenli Xu, Wei Cai
In this paper, we propose an operator learning method based on the multiscale Fourier neural operator (MscaleFNO) for inverse medium problems of Helmholtz equations. The MscaleFNO…

MscaleFNO: Multi-scale Fourier Neural Operator Learning for Oscillatory Function Spaces
Zhilin You, Zhenli Xu, Wei Cai
In this paper, a multi-scale Fourier neural operator (MscaleFNO) is proposed to reduce the spectral bias of the FNO in learning the mapping between highly oscillatory functions, wi…
