1 Introduction to deep reinforcement learning

In this chapter

  • You will learn what deep reinforcement learning is and how it is different from other machine learning approaches.
  • You will learn about the recent progress in deep reinforcement learning and what it can do for a variety of problems.
  • You will know what to expect from this book and how to get the most out of it.

I visualize a time when we will be to robots what dogs are to humans, and I’m rooting for the machines.

— Claude Shannon Father of the information age and contributor to the field of artificial intelligence

Humans naturally pursue feelings of happiness. From picking out our meals to advancing our careers, every action we choose is derived from our drive to experience rewarding moments in life. Whether these moments are self-centered pleasures or the more generous of goals, whether they bring us immediate gratification or long-term success, they’re still our perception of how important and valuable they are. And to some extent, these moments are the reason for our existence.
