Sparse Fourier Transform (SFT) algorithms constitute a transformative approach to spectral analysis by leveraging the inherent sparsity of signals in the frequency domain. In contrast to the ...

In January, four MIT researchers showed off a replacement for one of the most important algorithms in computer science. Dina Katabi, Haitham Hassanieh, Piotr Indyk, and Eric Price have created a ...

傅里叶变换 (Fourier Transform) 是一种数学函数，它将采样信号（波形）从其原始域（通常是时间或空间）分解为其组成的正弦波频率，反之亦然。 Fast Fourier Transform (FFT) 是一种离散傅里叶变换DFT的高效算法，称为FFT快速傅里叶变换。傅里叶变换是时域一频域变换 ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last ...

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 ...
