• Each KKNO layer acts as a controlled smoothing filter where kernel moments determine drift and diffusion, guaranteeing noise suppression and feature drift control.technical 95%
  Evidencepartial

  More precisely, each KKNO layer acts as a controlled smoothing filter: (Lnf)(x) = Z Kn(x, u)f(u/n)du with kernel momentsa(x), b(x) determining drift and diffusion. This guarantees noise suppression due to diffusion termb(x), feature drift control due toa(x), and high-order smoothness due to moment constraints.
