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 machine learning

The goal of any ML exercise is to learn a mapping F from an input space X to an output space y. Early machine learning methods required feature engineering to define the appropriate features, whereas DL methods can infer the features from the training data itself. DL works by hypothesizing a model M with random weights , formulating the task as an optimization problem over the parameters :

and using gradient descent to update the model weights over multiple iterations until the parameters converge:

Not surprisingly, GNNs follow this basic model as well.

However, as you have seen in previous chapters, ML and DL are often optimized for specific structures. For example, you might instinctively choose a simple FeedForward Network (FFN) or “dense” network when working with tabular data, a Convolutional Neural Network (CNN) when dealing with image data, and a Recurrent Neural Network (RNN) when dealing with sequence data like text...
