Overview of this book

Deep Learning with TensorFlow and Keras teaches you neural networks and deep learning techniques using TensorFlow (TF) and Keras. You'll learn how to write deep learning applications in the most powerful, popular, and scalable machine learning stack available. TensorFlow 2.x focuses on simplicity and ease of use, with updates like eager execution, intuitive higher-level APIs based on Keras, and flexible model building on any platform. This book uses the latest TF 2.0 features and libraries to present an overview of supervised and unsupervised machine learning models and provides a comprehensive analysis of deep learning and reinforcement learning models using practical examples for the cloud, mobile, and large production environments. This book also shows you how to create neural networks with TensorFlow, runs through popular algorithms (regression, convolutional neural networks (CNNs), transformers, generative adversarial networks (GANs), recurrent neural networks (RNNs), natural language processing (NLP), and graph neural networks (GNNs)), covers working example apps, and then dives into TF in production, TF mobile, and TensorFlow with AutoML.

Graph Neural Networks

In this chapter, we will look at a relatively new class of neural networks, the Graph Neural Network (GNN), which is ideally suited for processing graph data. Many real-life problems in areas such as social media, biochemistry, academic literature, and many others are inherently “graph-shaped,” meaning that their inputs are composed of data that can best be represented as graphs. We will cover what graphs are from a mathematical point of view, then explain the intuition behind “graph convolutions,” the main idea behind GNNs. We will then describe a few popular GNN layers that are based on variations of the basic graph convolution technique. We will describe three major applications of GNNs, covering node classification, graph classification, and edge prediction, with examples using TensorFlow and the Deep Graph Library (DGL). DGL provides the GNN layers we have just mentioned plus many more. In addition, it also provides some standard...
