Hands-On Generative Adversarial Networks with Keras

By: Rafael Valle

Overview of this book

Generative Adversarial Networks (GANs) have revolutionized the fields of machine learning and deep learning. This book will be your first step toward understanding GAN architectures and tackling the challenges involved in training them. This book opens with an introduction to deep learning and generative models and their applications in artificial intelligence (AI). You will then learn how to build, evaluate, and improve your first GAN with the help of easy-to-follow examples. The next few chapters will guide you through training a GAN model to produce and improve high-resolution images. You will also learn how to implement conditional GANs that enable you to control characteristics of GAN output. You will build on your knowledge further by exploring a new training methodology for progressive growing of GANs. Moving on, you'll gain insights into state-of-the-art models in image synthesis, speech enhancement, and natural language generation using GANs. In addition to this, you'll be able to identify GAN samples with TequilaGAN. By the end of this book, you will be well-versed with the latest advancements in the GAN framework using various examples and datasets, and you will have developed the skills you need to implement GAN architectures for several tasks and domains, including computer vision, natural language processing (NLP), and audio processing.

Improving Your First GAN

In this chapter, you will learn about the main challenges in training and understanding Generative Adversarial Networks (GANs), as well as how to solve them. You will learn about vanishing gradients, mode collapse, training instability, and other challenges. You will also learn about multiple deep-learning model architectures that have been successful using the GAN framework. Furthermore, you will learn to possibly improve your first GAN by implementing new loss functions and algorithms.

In this chapter we will continue to focus on the CIFAR-10 dataset and cover the following topics:

  • Challenges in training GANs
  • Tricks of the trade
  • GAN model architectures
  • GAN algorithms and loss functions
