Hands-On Intelligent Agents with OpenAI Gym

By: Palanisamy P

Overview of this book

Many real-world problems can be broken down into tasks that require a series of decisions to be made or actions to be taken. The ability to solve such tasks without a machine being programmed requires a machine to be artificially intelligent and capable of learning to adapt. This book is an easy-to-follow guide to implementing learning algorithms for machine software agents in order to solve discrete or continuous sequential decision making and control tasks. Hands-On Intelligent Agents with OpenAI Gym takes you through the process of building intelligent agent algorithms using deep reinforcement learning starting from the implementation of the building blocks for configuring, training, logging, visualizing, testing, and monitoring the agent. You will walk through the process of building intelligent agents from scratch to perform a variety of tasks. In the closing chapters, the book provides an overview of the latest learning environments and learning algorithms, along with pointers to more resources that will help you take your deep reinforcement learning skills to the next level.

Understanding the Mountain Car problem

For any reinforcement learning problem, two fundamental definitions concerning the problem are important, irrespective of the learning algorithm we use. They are the definitions of the state space and the action space. We mentioned earlier in this book that the state and action spaces could be discrete or continuous. Typically, in most problems, the state space consists of continuous values and is represented as a vector, matrix, or tensor (a multi-dimensional matrix). Problems and environments with discrete action spaces are relatively easy compared to continuous valued problems and environments. In this book, we will develop learning algorithms for a few problems and environments with a mix of state space and action space combinations so that you are comfortable dealing with any such variation when you start out on your own and develop...
