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.

Playing with Google Colab: CPUs, GPUs, and TPUs

Google offers a truly intuitive tool for training neural networks and for playing with TensorFlow at no cost. You can find an actual Colab, which can be freely accessed, at https://colab.research.google.com/ and if you are familiar with Jupyter notebooks you will find a very familiar web-based environment here. Colab stands for Colaboratory and is a Google research project created to help disseminate machine learning education and research. We will see the difference between CPUs, GPUs, and TPUs in Chapter 15, Tensor Processing Unit.

For now, it’s important to know that CPUs are generic processing units, while GPUs and TPUs are accelerators, specific processing units suitable for deep learning. Let’s see how it works, starting with the screenshot shown in Figure 1.23:

By accessing Colab, we can either check a listing of notebooks generated in the past or we...
