Overview of this book

With the surge in artificial intelligence in applications catering to both business and consumer needs, deep learning is more important than ever for meeting current and future market demands. With this book, you’ll explore deep learning, and learn how to put machine learning to use in your projects. This second edition of Python Deep Learning will get you up to speed with deep learning, deep neural networks, and how to train them with high-performance algorithms and popular Python frameworks. You’ll uncover different neural network architectures, such as convolutional networks, recurrent neural networks, long short-term memory (LSTM) networks, and capsule networks. You’ll also learn how to solve problems in the fields of computer vision, natural language processing (NLP), and speech recognition. You'll study generative model approaches such as variational autoencoders and Generative Adversarial Networks (GANs) to generate images. As you delve into newly evolved areas of reinforcement learning, you’ll gain an understanding of state-of-the-art algorithms that are the main components behind popular games Go, Atari, and Dota. By the end of the book, you will be well-versed with the theory of deep learning along with its real-world applications.

Generative Adversarial networks

In this section, we'll talk about arguably the most popular generative model today: the GANs framework. It was first introduced in 2014 in the landmark paper Generative Adversarial Nets(http://papers.nips.cc/paper/5423-generative-adversarial-nets.pdf) by Ian J. Goodfellow, Jean Pouget-Abadie, Mehdi Mirza, Bing Xu, David Warde-Farley, Sherjil Ozair Aaron Courville, and Yoshua Bengio. The GANs framework can work with any type of data, but it's most popular application by far is to generate images, and we'll discuss them in this context only. Let's see how it work:

A GAN system

A GAN is a system of two components (neural networks):

  • Generator: This is the generative model itself. It takes a probability distribution (random noise) as input and tries to generate a realistic output image. Its purpose is similar to the decoder part...
