Discriminator Working #45

It is because of feature matching. It updates hidden layers in discriminator, so that D(x) and D(G(z)) get closer. From the paper,

a feature matching term [40], which essentially is a perceptual similarity measure, computed using discriminator (it helps with the stability of the training):
