What is a General Adversarial Network (GAN)?

A General Adversarial Network (GAN) is a type of neural network that is used for generating new data that resembles the training data. GANs consist of two parts: a generator, which creates new data, and a discriminator, which tries to distinguish the generated data from the real data.

How does a GAN work?

A GAN works by training the generator and the discriminator in tandem. The generator tries to create data that the discriminator cannot distinguish from the real data, while the discriminator tries to get better at distinguishing real data from generated data. This creates a kind of competition, where the generator continually improves its ability to create realistic data, and the discriminator continually improves its ability to detect fake data.

The training process continues until the discriminator can no longer distinguish the generated data from the real data.

What are the applications of GANs?

GANs have a wide range of applications. They can be used to generate realistic images, to create artificial voices, to produce synthetic data for training other models, and more. However, they also raise ethical and legal issues, as they can be used to create deepfakes or to generate misleading information.
