The core of GAN can be summarized as training two networks simultaneously: a generator (G) and a discriminator (D). D is a classifier to distinguish real data from fake data. G confuses D by generating data as real as possible. We propose a new generative model estimation procedure that sidesteps these difficulties.1.
