Generative AI -Role of the Generator and Discriminator

Role of the Generator and Discriminator

In the GAN design, the generator and discriminator play different roles. The main job of the generator is to turn random input, usually noise, into real data. It gets better at mapping the random noise vector to the data space over time thanks to the discriminator's input. At first, the generator's output is very different from the real data. But as training goes on, it learns to make more accurate and real data samples.

The discriminator gives the creator feedback on the things they make. It has been taught to tell the difference between real data and the fake data that the generator makes. The discriminator helps the generator get better by telling it how realistic the data it makes is during the training process. If the discriminator can tell the difference between real and fake data, the creator has to make better data to trick the discriminator. This training with opponents keeps going until the generator makes data that the discriminator can't confidently tell apart from real data.​
