Analysis questions OpenAI's claimed faster Fourier transform math

Read original source →argmin.net

Blog post examines part of OpenAI's math repository that claims to compute faster Fourier transforms, adding tutorial material on signal processing and computational complexity. It contrasts the claim with the Cooley-Tukey FFT, which computes a length-n transform in under 5n log2 n operations — a 20-fold speedup over n² at n=1,000.
