Generative adversarial network.

Generative Adversarial Networks use a unique approach to generating new data by pitting two neural networks against each other in a competitive setting. One network attempts to create new data. The other network attempts to discern whether or not it’s fake. Through repeated training, both networks become better at their jobs. The second category relies on learning the image prior model in terms of generative adversarial networks (GAN) which consists of a generator network G and a discriminator network D [28], [29].
