Implementation of Reinforcement Learning Algorithms in Python

Jul 7, 2022 | Data Science

Welcome to the fascinating world of Reinforcement Learning (RL). In this article, we will explore the implementation of selected RL algorithms using Python and TensorFlow. With hands-on examples, you’ll not only grasp the concepts but also learn how to implement them effectively.

Understanding Reinforcement Learning

Reinforcement Learning is like training a dog: you’re rewarding it with treats when it performs well (positive reinforcement) and sometimes saying “no” when it does something wrong. In the same way, agents in RL learn to make decisions by maximizing cumulative rewards through exploration and exploitation. Let’s dive into the algorithms you can implement!

Implemented Algorithms

Below is a list of the main algorithms we’ve implemented. These algorithms cater to various methods of learning.

Working Examples

For each algorithm, we provide working examples tailored for better understanding:

Dependencies

To smoothly run the implementations, ensure you have these dependencies:

  • Python 2.7
  • Numpy
  • Tensorflow 0.12.1
  • OpenAI Gym (with Atari) 0.8.0
  • matplotlib (optional)

Testing Your Implementations

We provide unit tests to validate your implementations. Use the following command to run your tests:

python test_[class].py

For test coverage, ensure you have “coverage” and “nose” installed, and run:

nosetests --with-coverage --cover-package=.

Troubleshooting

While implementing these algorithms, you might run into some common issues. Here are some troubleshooting tips:

  • Ensure all dependencies are correctly installed and your Python environment is set up.
  • Check compatibility of TensorFlow version; it might lead to unexpected behaviors if it’s outdated.
  • Inspect your code for typos or logical errors, especially in the networking or reward functions.
