What is a Generative Adversarial Network? A Generative Adversarial Network (GAN) is an advanced structure in artificial intelligence, characterized by two neural networks contesting against each other. One network, the generator, creates data mimicking real datasets, while the other, the discriminator, evaluates its authenticity. This competition enhances the accuracy and realism of the generated data.

Dive deep into the world of GANs with guidance from the AI specialists at All About AI. Our comprehensive articles and insights break down intricate AI concepts, making them accessible to everyone.

Examples of Generative Adversarial Network
