Reinforcement Learning with TensorFlow

By: Sayon Dutta

Overview of this book

Reinforcement learning (RL) allows you to develop smart, quick and self-learning systems in your business surroundings. It's an effective method for training learning agents and solving a variety of problems in Artificial Intelligence - from games, self-driving cars and robots, to enterprise applications such as data center energy saving (cooling data centers) and smart warehousing solutions. The book covers major advancements and successes achieved in deep reinforcement learning by synergizing deep neural network architectures with reinforcement learning. You'll also be introduced to the concept of reinforcement learning, its advantages and the reasons why it's gaining so much popularity. You'll explore MDPs, Monte Carlo tree searches, dynamic programming such as policy and value iteration, and temporal difference learning such as Q-learning and SARSA. You will use TensorFlow and OpenAI Gym to build simple neural network models that learn from their own actions. You will also see how reinforcement learning algorithms play a role in games, image processing and NLP. By the end of this book, you will have gained a firm understanding of what reinforcement learning is and understand how to put your knowledge to practical use by leveraging the power of TensorFlow and OpenAI Gym.

Summary


We saw that using parallel learners to update a shared model produced a great improvement on the learning process. We learned about the reason behind the use of asynchronous methods in deep learning and their different variants, including asynchronous one-step Q-learning, asynchronous one-step SARSA, asynchronous n-step Q-learning, and asynchronous advantage actor-critic. We also learned to implement the A3C algorithm, where we made an agent learn to play the games Breakout and Doom.

In the coming chapters, we will focus on different domains and how deep reinforcement learning is being, and can be, applied.
