What is General Adversarial Network ( GAN )?

[board-infinity]

A generative adversarial network (GAN) is a machine learning (ML) model in which two neural networks compete with each other to become more accurate in their predictions. GANs typically run unsupervised and use a cooperative zero-sum game framework to learn.

• The two neural networks that make up a GAN are referred to as the generator and the discriminator. The generator is a convolutional neural network and the discriminator is a deconvolutional neural network. The goal of the generator is to artificially manufacture outputs that could easily be mistaken for real data. The goal of the discriminator is to identify which outputs it receives have been artificially created.

• Essentially, GANs create their own training data. As the feedback loop between the adversarial networks continues, the generator will begin to produce higher-quality output and the discriminator will become better at flagging data that has been artificially created.
