Generative adversarial network

A type of artificial intelligence model in which two neural networks compete against each other to generate realistic synthetic data, such as images or text.

The Explain card

Plain English
A generative adversarial network (GAN) pits two neural networks against each other: a generator makes synthetic data and a discriminator tries to spot the fakes. Each improves by trying to beat the other.
Example
A GAN trained on employee photos produces realistic faces for a fake social media profile used in a social engineering campaign against the company.
Why it matters
GANs helped create the deepfake era. Understanding the generator-versus-discriminator loop also explains why detection is an arms race: every better detector trains a better forger.
Hook
Forger and art expert locked in a room until the forger wins.
