Fourier Transforms Explained: From Signals to Spectral Bias

A practical guide to Fourier transforms, spectral bias, and choosing a useful representation: why audio and images need different spectral tools, how Fourier features change learning, and where FFT mixing helps or loses information.

The Frequency Domain: How Fourier Transforms Secretly Powered Everything We Built

A practitioner-level synthesis of twelve weeks of tutorials through one lens — spectral bias, Fourier features, FFT-based token mixing, Bochner's theorem, and neural operators — showing that positional encodings, kernels, state-space models and diffusion schedules are the same idea in different clothes.
