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 basics

Mathematically speaking, a graph G is a data structure consisting of a set of vertices (also called nodes) V, connected to each other by a set of edges E, i.e:

A graph can be equivalently represented as an adjacency matrix A of size (n, n) where n is the number of vertices in the set V. The element A[I, j] of this adjacency matrix represents the edge between vertex i and vertex j. Thus the element A[I, j] = 1 if there is an edge between vertex i and vertex j, and 0 otherwise. In the case of weighted graphs, the edges might have their own weights, and the adjacency matrix will reflect that by setting the edge weight to the element A[i, j]. Edges may be directed or undirected. For example, an edge representing the friendship between a pair of nodes x and y is undirected, since x is friends with y implies that y is friends with x. Conversely, a directed edge can be one in a follower network (social media), where x following y does not imply that y follows x. For...
