What Is Generative Adversarial Networks (GAN)?

The Generative Adversarial Networks (GAN) is, in fact, never a single network. It is a set of networks, at least two, operating at the same place but working against each other. Each of the networks brings its own unique set of results. For instance, in GAN approach, the first network creates realistic images, while the second one identifies whether those are real or not. It is like the first network is synthesizing something and the second one is monitoring its operations and controls what it creates.
