« StyleGAN—you know the deepfakes of people—there's a website [called] ThisPersonDoesNotExist that's all using a GAN, using StyleGAN, and the way the GAN works is that we have these two networks, a generator and a discriminator. When I'm teaching about this I sort of introduce this like one person is a forger—that's the generator—and then the discriminator is a detective. So if someone's forging money, trying to make fake bank notes, then the discriminator is the person at the bank trying to figure out is this real money or is this fake money, and these are extremely effective. So the discriminator is trying to tell what's a real image compared to what's being generated, what's fake, and the generator's got this adversarial opposite objective which is: I want to generate things that trick the discriminator, passed off as being real. In this setup, the generator has one objective, and that objective is: I just need to trick this other network, I just need to get my bank notes passed off as real money, so to speak, or get my images of people or whatever passed off as being real, training data. » · MIARA dossier thématique
