time the goal of the discriminator D is to output a value D of G of Z that is near zero I'm sorry I realized there's a mistake in the slide actually it's backwards the discriminator wants to make the value in this case be near zero and the generator would like to make it be near one so the discriminator would like to reject these samples as being fake well the generator would like to fool the discriminator into thinking that they're real you can think of the generator and the discriminator as being a little bit like counterfeit
