SIREN

A comeback of signal processing? A video from authors and from Yannic, and the arxiv paper, and a nice website. The 3d reconstruction is very convincing. btw, another video presentation of implicit representation.

Some remarks:

  1. Represent signals as functions instead multidimensional data (not a completely new idea as the authors pointed out)
  2. Match not just the signal itself but also its derivative
  3. Use sinsoidal activation function. This allows derivative of the network is still well-defined (and still a siren).
