How do we train GAN model?

Steps to train a GAN

1. Step 1: Define the problem.
2. Step 2: Define architecture of GAN.
3. Step 3: Train Discriminator on real data for n epochs.
4. Step 4: Generate fake inputs for generator and train discriminator on fake data.
5. Step 5: Train generator with the output of discriminator.

What is GAN model?

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. Essentially, GANs create their own training data.

Who introduced GANs?

Ian Goodfellow
A generative adversarial network (GAN) is a class of machine learning frameworks designed by Ian Goodfellow and his colleagues in 2014.

How are generative adversarial networks used in deep learning?

Generative Adversarial Networks, or GANs, are a deep-learning-based generative model. More generally, GANs are a model architecture for training a generative model, and it is most common to use deep learning models in this architecture.

How are generative adversarial networks based on game theory?

Generative adversarial networks are based on a game theoretic scenario in which the generator network must compete against an adversary. The generator network directly produces samples. Its adversary, the discriminator network, attempts to distinguish between samples drawn from the training data and samples drawn from the generator.

How are generator and discriminator models trained together?

The two models are trained together in a zero-sum game, adversarial, until the discriminator model is fooled about half the time, meaning the generator model is generating plausible examples.

Which is an example of a generative model in deep learning?

Deep learning methods can be used as generative models. Two popular examples include the Restricted Boltzmann Machine, or RBM, and the Deep Belief Network, or DBN. Two modern examples of deep learning generative modeling algorithms include the Variational Autoencoder, or VAE, and the Generative Adversarial Network, or GAN.
