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 customizations

We have seen how to build and train GNNs for common graph ML tasks. However, for convenience, we have chosen to use prebuilt DGL graph convolution layers in our models. While unlikely, it is possible that you might need a layer that is not provided with the DGL package. DGL provides a message passing API to allow you to build custom graph layers easily. In the first part of this section, we will look at an example where we use the message-passing API to build a custom graph convolution layer.

We have also loaded datasets from the DGL data package for our examples. It is far more likely that we will need to use our own data instead. So, in the second part of this section, we will see how to convert our own data into a DGL dataset.

Custom layers and message passing

Although DGL provides many graph layers out of the box, there may be cases where the ones provided don’t meet our needs exactly and we need to build your own.

Fortunately, all...
