Generative networks as inverse problems with Scattering transforms

1 code implementation • ICLR 2018 • Tomás Angles, Stéphane Mallat

Generative Adversarial Nets (GANs) and Variational Auto-Encoders (VAEs) provide impressive image generations from Gaussian white noise, but the underlying mathematics are not well understood.
