FDA: Fourier Domain Adaptation for Semantic Segmentation [PDF]
Computer Vision and Pattern Recognition, 2020 We describe a simple method for unsupervised domain adaptation, whereby the discrepancy between the source and target distributions is reduced by swapping the low-frequency spectrum of one with the other. We illustrate the method in semantic segmentation,

Quantum Fourier Transform Has Small Entanglement
PRX Quantum, 2023 The quantum Fourier transform (QFT) is a key component of many important quantum algorithms, most famously being the essential ingredient in Shor’s algorithm for factoring products of primes.

Explicit Hermite-type eigenvectors of the discrete Fourier transform [PDF]
, 2015 The search for a canonical set of eigenvectors of the discrete Fourier transform has been ongoing for more than three decades. The goal is to find an orthogonal basis of eigenvectors which would approximate Hermite functions -- the eigenfunctions of the ...

The Chromatic Fourier Transform
Forum of Mathematics, PiWe develop a general theory of higher semiadditive Fourier transforms that includes both the classical discrete Fourier transform for finite abelian groups at height $n=0$ , as well as a certain duality for the $E_n$ -(co)homology of $\pi
