"> - The main focus for GAN is to generate data from scratch.\n",
"> - It brings us closer to understanding intelligence.\n",
"- It trains two deep networks, called Generator and Discriminator, that compete and cooperate with each other. In the course of training, both networks eventually learn how to perform their tasks.\n",
"> > - The generator never actually sees examples from the domain and is adapted based on how well the discriminator performs."

Generative Adversial Network:

"The goal is to train a generator model, not a discriminator model, and that is where the complexity of GANs truly lies."
We will define a small latent space of five dimensions and use the standard approach in the GAN literature of using a Gaussian distribution for each variable in the latent space. We will generate new inputs by drawing random numbers from a standard Gaussian distribution, i.e. mean of zero and a standard deviation of one.
- Single Hidden Layer with 5 nodes
- ReLU activation Function
- He weight initialization
- Output layer will have 2 nodes+ will use linear activation function
