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.

Tensor Processing Unit

This chapter introduces the Tensor Processing Unit (TPU), a special chip developed at Google for ultra-fast execution of neural network mathematical operations. As with Graphics Processing Units (GPUs), the idea here is to have a special processor focusing only on very fast matrix operations, with no support for all the other operations normally supported by Central Processing Units (CPUs). However, the additional improvement with TPUs is to remove from the chip any hardware support for graphics operations normally present in GPUs (rasterization, texture mapping, frame buffer operations, and so on). Think of a TPU as a special purpose co-processor specialized for deep learning, being focused on matrix or tensor operations. In this chapter, we will compare CPUs and GPUs with the four generations of TPUs and with Edge TPUs. All these accelerators are available as of April 2022. The chapter will include code examples of using TPUs.
