Implementing scalable deep Q-learning algorithms using Ray

In this section, we will implement a parallelized DQN variate using the Ray library. Ray is a powerful, general-purpose, yet simple framework for building and running distributed applications on a single machine as well as on large clusters. Ray has been built for applications that have heterogenous computational needs in mind. This is exactly what modern DRL algorithms require as they involve a mix of long and short running tasks, usage of GPU and CPU resources, and more. In fact, Ray itself has a powerful RL library that is called RLlib. Both Ray and RLlib have been increasingly adopted in academia and industry.

Info

For a comparison of Ray to other distributed backend frameworks such as Spark and Dask, see https://bit.ly/2T44AzK. You will see that Ray is a very competitive alternative, even beating Python's own multiprocessing implementation in some benchmarks.

Practical Reinforcement Learning

Practical Reinforcement Learning

Reinforcement learning (RL) is becoming a popular tool for constructing autonomous systems that improve themselves with experience. We will break the RL framework into its core building blocks, and provide you with details of each element. This book is divided into three parts. The first part defines Reinforcement Learning and describes the basics and the Python and Java frameworks, which we are going to use later in the book. The second part discusses learning techniques with basic algorithms such as Temporal Difference, Monte Carlo, and Policy Gradient—all with practical examples. Lastly, in the third part we apply Reinforcement Learning with the most recent and widely used algorithms, via practical applications.
