GAN = Generative Adversarial Network
Adversarial = Two networks that fight against each other. They're called the Generator, and the Discriminator.
Analogy:
- A forger (the generator) and a bank (the discriminator).
- At first, both start off really dumb. The forger will draw up really bad fakes. The bank will reject it, and then the forger will learn how to produce a slightly better fake. Through more and more training steps, both the forger and the bank get better and better. The forger makes better fakes, and the bank will get better at telling fakes from real dollars.
