The Fourier Neural Operator (FNO) [1] is a neural operator with an integral kernel parameterized in Fourier space. This allows for an expressive and efficient architecture. Applications of the FNO ...

This implements MATLAB + CUDA programming for the acceleration of Fourier ptychographic microscopy (FPM) reconstruction. FPM's forward and backward progress are all calculated purely by CUDA in ...

In this work, Fourier-series representation of a discontinuous function is used to highlight and clarify the controversial problem of finding the value of the function at a point of discontinuity.
