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.

Summary

In this chapter, we discussed transformers, a deep learning architecture that has revolutionized the traditional natural language processing field. We started reviewing the key intuitions behind the architecture, and various categories of transformers together with a deep dive into the most popular models. Then, we focused on implementations both based on vanilla architecture and on popular libraries such as Hugging Face and TFHub. After that, we briefly discussed evaluation, optimization, and some of the best practices commonly adopted when using transformers. The last section was devoted to reviewing how transformers can be used to perform computer vision tasks, a totally different domain from NLP. That requires a careful definition of the attention mechanism. In the end, attention is all you need! And at the core of attention is nothing more than the cosine similarity between vectors.

The next chapter is devoted to unsupervised learning.
