So, let's try to better understand how the different parts of the GAN work together to generate synthetic data. Consider the parameterized function (G) (you know, the kind we usually approximate using a neural network). This will be our generator, which samples its input vectors (z) from some latent probability distribution, and transforms them into synthetic images. Our discriminator network (D), will then be presented with some synthetic images produced by our generator, mixed among real images, and attempt to classify real from forgery. Hence, our discriminator network is simply a binary classifier, equipped with something like a sigmoid activation function. Ideally, we want the discriminator to output high values when presented with real images, and low values when presented with generated fakes. Conversely, we want our generator network to try...

Overview of this book
Neural networks are used to solve a wide range of problems in different areas of AI and deep learning.
Hands-On Neural Networks with Keras will start with teaching you about the core concepts of neural networks. You will delve into combining different neural network models and work with real-world use cases, including computer vision, natural language understanding, synthetic data generation, and many more. Moving on, you will become well versed with convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory (LSTM) networks, autoencoders, and generative adversarial networks (GANs) using real-world training datasets. We will examine how to use CNNs for image recognition, how to use reinforcement learning agents, and many more. We will dive into the specific architectures of various networks and then implement each of them in a hands-on manner using industry-grade frameworks.
By the end of this book, you will be highly familiar with all prominent deep learning models and frameworks, and the options you have when applying deep learning to real-world scenarios and embedding artificial intelligence as the core fabric of your organization.
