Welcome to the Reinforcement Learning (RL) Getting Started Guide! If you're new to RL or looking to expand your knowledge, this page will serve as a comprehensive overview to help you dive into the fascinating world of RL.

What is Reinforcement Learning?

Reinforcement Learning is a type of machine learning where an agent learns to make decisions by performing actions in an environment to achieve a goal. The agent receives rewards or penalties based on the actions it takes, and through this feedback, it learns to optimize its behavior.

Key Concepts

Here are some of the key concepts in RL:

  • Agent: The decision-making entity in the environment.
  • Environment: The context in which the agent operates, providing feedback in the form of rewards or penalties.
  • State: The current situation or context in which the agent operates.
  • Action: The decision made by the agent to transition from one state to another.
  • Reward: The feedback received by the agent after taking an action.

Getting Started

To get started with RL, you'll need to familiarize yourself with the following:

  • Python: The primary programming language used in RL.
  • Reinforcement Learning Libraries: Such as OpenAI Gym and Stable Baselines.
  • Understanding of Machine Learning Basics: Including concepts like supervised learning, unsupervised learning, and neural networks.

Learning Resources

To help you on your journey, here are some resources:

  • OpenAI Gym: A toolkit for developing and comparing reinforcement learning algorithms.
  • Stable Baselines: A set of high-quality implementations of reinforcement learning algorithms.
