Overview of this book

Various intelligent applications such as video games, inventory management software, warehouse robots, and translation tools use reinforcement learning (RL) to make decisions and perform actions that maximize the probability of the desired outcome. This book will help you to get to grips with the techniques and the algorithms for implementing RL in your machine learning models. Starting with an introduction to RL, youÔÇÖll be guided through different RL environments and frameworks. YouÔÇÖll learn how to implement your own custom environments and use OpenAI baselines to run RL algorithms. Once youÔÇÖve explored classic RL techniques such as Dynamic Programming, Monte Carlo, and TD Learning, youÔÇÖll understand when to apply the different deep learning methods in RL and advance to deep Q-learning. The book will even help you understand the different stages of machine-based problem-solving by using DARQN on a popular video game Breakout. Finally, youÔÇÖll find out when to use a policy-based method to tackle an RL problem. By the end of The Reinforcement Learning Workshop, youÔÇÖll be equipped with the knowledge and skills needed to solve challenging problems using reinforcement learning.

Basics of PyTorch

In this chapter, we will use PyTorch to build deep learning solutions. The obvious question that comes to mind is, why PyTorch? The following describes a number of reasons as to why we should use PyTorch to build deep learning models:

  • Pythonic deep integration:

    The learning curve of PyTorch is smooth due to the Pythonic approach of the coding style and the adoption of object-oriented methods. One example of this is deep integration with the NumPy Python library, where you can easily convert a NumPy array into a torch tensor and vice versa. Also, Python debuggers work smoothly with PyTorch, which makes code debugging easier when using PyTorch.

  • Dynamic graph computation:

    Many other deep learning frameworks come with a static computation graph; however, in PyTorch, dynamic graph computation is supported, which gives the developer a far more in-depth understanding of what is going on in each algorithm and allows them to change the network behavior programmatically...
