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.

Autoencoders

Autoencoders are neural networks that learn by unsupervised learning, also sometimes called semi-supervised learning, since the input is treated as the target too. In this chapter, you will learn about and implement different variants of autoencoders and eventually learn how to stack autoencoders. We will also see how autoencoders can be used to create MNIST digits, and finally, also cover the steps involved in building a long short-term memory autoencoder to generate sentence vectors. This chapter includes the following topics:

  • Vanilla autoencoders
  • Sparse autoencoders
  • Denoising autoencoders
  • Convolutional autoencoders
  • Stacked autoencoders
  • Generating sentences using LSTM autoencoders
  • Variational autoencoders for generating images
