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.

Common graph applications

We will now look at some common applications of GNNs. Typically, applications fall into one of the three major classes listed below. In this section, we will see code examples on how to build and train GNNs for each of these tasks, using TensorFlow and DGL:

  • Node classification
  • Graph classification
  • Edge classification (or link prediction)

There are other applications of GNNs as well, such as graph clustering or generative graph models, but they are less common and we will not consider them here.

Node classification

Node classification is a popular task on graph data. Here, a model is trained to predict the node category. Non-graph classification methods can use the node feature vectors alone to do so, and some pre-GNN methods such as DeepWalk and node2vec can use the adjacency matrix alone, but GNNs are the first class of techniques that can use both the node feature vectors and the connectivity information together...
