Chapter 20. Looking Ahead

Over the past few hundred pages, we have faced numerous challenges, to which we applied reinforcement and deep learning algorithms. To conclude our reinforcement learning (RL) journey, this chapter will look at several aspects of the field that we have not covered yet. We will start by looking at several of the drawbacks of reinforcement learning, which any practitioner or researcher should be aware of. To end on a positive note, we will follow up by describing numerous exciting academic developments and achievements the field has seen in recent years.
