A deepfake video, still image, or audio recording is the product of a
clever bit of coding called a “generative adversarial network,” or GAN. A
GAN has two components: a discriminator and a generator. The
discriminator is trying to tell fake media from real media. The
generator is trying to fool the discriminator with increasingly
realistic-seeming fakes."
