Generative Adversarial Networks

Definition

Generative Adversarial Networks (GANs) are a class of machine learning frameworks where two neural networks, a generator and a discriminator, compete against each other to create data that is indistinguishable from real data. This technique is crucial in advancing artificial intelligence applications, especially in fields like image synthesis and simulation, which can significantly enhance research efforts in fusion technology by modeling complex systems and optimizing experimental designs.
