A new algorithm performs Fourier transforms using a minimal number of samples. The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing.
A Physics-Informed Neural Operator (PINO) implementation for solving 2D Heat Equation using Fourier analysis techniques. This project was developed as part of a Master's thesis on balancing data ...
Abstract: In order to improve the computing efficiency and accuracy of Discrete Fractional Fourier Transform (DFRFT), a fast algorithm derived from Fast Fourier Transform is introduced on the basis of ...
Modern scientific research produces datasets of increasing size and complexity that require dedicated numerical methods to be processed. In many cases, the analysis of spectroscopic data involves the ...
