Learning Under the Fourier Transform Algorithm
, 1996
"... this paper was to implement the Fourier Transform algorithm for boolean function in an efficient way so that, as we shall demonstrate, it is not only a useful theoretical tool but also a practical one. Note that the procedure scales linearly with the number of input variables, conveniently allowing ..."

An Equivariant Fast Fourier Transform Algorithm
"... This paper presents a generalization of the CooleyTukey fast Fourier transform algorithm that respects group symmetries. The algorithm, when applied to a function invariant under a group of symmetries, fully exploits these symmetries to reduce both the number of arithmetic operations and the amount ..."

Implementation issues in the Fourier Transform algorithm
 Proceedings of the Neural Information Processing Systems
, 1995
"... The Fourier transform of functions with boolean inputs has received considerable attention in the last few years in the Computational Learning Theory community, and has come to play an important role in proving many important learnability results. The aim of this work is to demonstrate that the Four ..."

Optimal multicriteria approach to the iterative Fourier transform algorithm

extremely powerful but also very time consuming. We extend this multicriteria approach to the Iterative Fourier Transform Algorithm (IFTA), which helps to reduce computation time dramatically, especially for multilevel domains. Simulations as well as experimental validations are provided.
An Improved Quantum Fourier Transform Algorithm and Applications
 In Proceedings of the 41st Annual Symposium on Foundations of Computer Science
, 2000
"... We give an algorithm for approximating the quantum Fourier transform over an arbitrary Z p which requires only O(n log n) steps where n = log p to achieve an approximation to within an arbitrary inverse polynomial in n. This improves the method of Kitaev [11] which requires time quadratic in n. Thi ..."
