The classic analogy is the counterfeiter (generator) and FBI agent (discriminator). The counterfeiter is constantly looking for new ways to produce fake documents that can pass the FBI agent's tests. Let's break it down into a set of goals:
- Counterfeiter (generator) goal: Produce products so that the cop cannot distinguish between the real and fake ones
- Cop (discriminator) goal: Detect anomalous products by using prior experience to classify real and fake products
