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.

Differences between discriminative and generative models

Given some data points, the discriminative model learns to classify the data points into their respective classes by learning the decision boundary that separates the classes in an optimal way. The generative models can also classify given data points, but instead of learning the decision boundary, they learn the characteristics of each of the classes.

For instance, let's consider the image classification task for predicting whether a given image is an apple or an orange. As shown in the following figure, to classify between apple and orange, the discriminative model learns the optimal decision boundary that separates the apples and oranges classes, while generative models learn their distribution by learning the characteristics of the apple and orange classes:

To put it simply, discriminative models learn to find...
