Idea Notes

Idea note — treat the weight-space loss surface as a signal with a Fourier spectrum over any bounded weight box, and ask whether its frequency structure (learned cheaply, then exploited via mode phase/interference) can locate the deepest minima. Contains a full literature survey: what exists, the nearest neighbors, and where the idea breaks.

Idea note — represent neural shapes (SDF/NeRF) directly as 3D Fourier spectra and exploit analytic frequency-domain structure for collision detection. Explores prior art, where the 'analytic collision' claim holds, and concrete research directions.
