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.

The OpenAI Gym


In order to download and install OpenAI Gym, you can use any of the following options:

$ git clone https://github.com/openai/gym 
$ cd gym 
$ sudo pip install -e . # minimal install

This will do the minimum install. You can later run the following to do a full install:

$ sudo pip install -e .[all]

You can also fetch Gym as a package for different Python versions as follows:

For Python 2.7, you can use the following options:

$ sudo pip install gym              # minimal install
$ sudo pip install gym[all]         # full install
$ sudo pip install gym[atari]       #for Atari specific environment installation

For Python 3.5, you can use the following options:

$ sudo pip3 install gym              # minimal install
$ sudo pip3 install gym[all]         # full install
$ sudo pip install gym[atari]       #for Atari specific environment installation
