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.

An overview of popular and well-known models

After the seminal paper Attention is All You Need, a very large number of alternative transformer-based models have been proposed. Let’s review some of the most popular and well-known ones.

BERT

BERT, or Bidirectional Encoder Representations from Transformers, is a language representation model developed by the Google AI research team in 2018. Let’s go over the main intuition behind that model:

  1. BERT considers the context of each word from both the left and the right side using the so-called “bidirectional self-attention.”
  2. Training happens by randomly masking the input word tokens, and avoiding cycles so that words cannot see themselves indirectly. In NLP jargon, this is called “fill in the blank.” In other words, the pretraining task involves masking a small subset of unlabeled inputs and then training the network to recover these original inputs. (This is an example of...
