Overview of this book

Deep learning is one of the most popular domains in the AI space that allows you to develop multi-layered models of varying complexities. This book introduces you to popular deep learning algorithms—from basic to advanced—and shows you how to implement them from scratch using TensorFlow. Throughout the book, you will gain insights into each algorithm, the mathematical principles involved, and how to implement it in the best possible manner. The book starts by explaining how you can build your own neural networks, followed by introducing you to TensorFlow, the powerful Python-based library for machine learning and deep learning. Moving on, you will get up to speed with gradient descent variants, such as NAG, AMSGrad, AdaDelta, Adam, and Nadam. The book will then provide you with insights into recurrent neural networks (RNNs) and LSTM and how to generate song lyrics with RNN. Next, you will master the math necessary to work with convolutional and capsule networks, widely used for image recognition tasks. You will also learn how machines understand the semantics of words and documents using CBOW, skip-gram, and PV-DM. Finally, you will explore GANs, including InfoGAN and LSGAN, and autoencoders, such as contractive autoencoders and VAE. By the end of this book, you will be equipped with all the skills you need to implement deep learning in your own projects.

Summary

We started this chapter by understanding the difference between generative and discriminative models. We learned that the discriminative models learn to find the good decision boundary that separates the classes in an optimal way, while the generative models learn about the characteristics of each class.

Later, we understood how GANs work. They basically consist of two neural networks called generators and discriminators. The role of the generators is to generate a new image by learning the real data distribution, while the discriminator acts as a critic and its role is to tell us whether the generated image is from the true data distribution or the fake data distribution, basically whether it is a real image or a fake image.

Next, we learned about DCGAN where we basically replace the feedforward neural networks in the generator and discriminator with convolutional neural...
