A Generative Adversarial Network (GAN) is a class of machine learning models consisting of two neural networks: a generator and a discriminator. The generator network generates synthetic data (such as images, text, or audio) that resembles real data, while the discriminator network tries to distinguish between the generated data and real data. The two networks are trained together in a competitive process, with the goal of improving the quality of the generated data over time. GANs have been successful in generating realistic and high-quality synthetic data, and they have applications in image synthesis, data augmentation, and generative modeling.
