Overview of this book

Deep Reinforcement Learning Hands-On, Second Edition is an updated and expanded version of the bestselling guide to the very latest reinforcement learning (RL) tools and techniques. It provides you with an introduction to the fundamentals of RL, along with the hands-on ability to code intelligent learning agents to perform a range of practical tasks. With six new chapters devoted to a variety of up-to-the-minute developments in RL, including discrete optimization (solving the Rubik's Cube), multi-agent methods, Microsoft's TextWorld environment, advanced exploration techniques, and more, you will come away from this book with a deep understanding of the latest innovations in this emerging field. In addition, you will gain actionable insights into such topic areas as deep Q-networks, policy gradient methods, continuous control problems, and highly scalable, non-gradient methods. You will also discover how to build a real hardware robot trained with RL for less than $100 and solve the Pong environment in just 30 minutes of training using step-by-step code optimization. In short, Deep Reinforcement Learning Hands-On, Second Edition, is your companion to navigating the exciting complexities of RL as it helps you attain experience and knowledge through real-world examples.

Deep Learning with PyTorch

In the previous chapter, you became familiar with open source libraries, which provided you with a collection of reinforcement learning (RL) environments. However, recent developments in RL, and especially its combination with deep learning (DL), now make it possible to solve much more challenging problems than ever before. This is partly due to the development of DL methods and tools. This chapter is dedicated to one such tool, PyTorch, which enables us to implement complex DL models with just a bunch of lines of Python code.

The chapter doesn't pretend to be a complete DL manual, as the field is very wide and dynamic; however, we will cover:

  • The PyTorch library specifics and implementation details (assuming that you are already familiar with DL fundamentals)
  • Higher-level libraries on top of PyTorch, with the aim of simplifying common DL problems
  • The library PyTorch ignite, which will be used in some examples
