Introduction to "Rainbow is all you need"

"Rainbow is all you need" is an educational project designed to guide individuals through the journey of enhancing reinforcement learning (RL) agents. It takes users from the basic Deep Q-Network (DQN) to the comprehensive Rainbow framework. This project is ideal for those looking to see their RL agents perform optimally, like smoothly maneuvering on Atari video games.

Project Structure

The project is composed of a series of tutorial chapters, each providing both theoretical insights and practical, object-oriented coding implementations. These tutorials are accessible and can be executed immediately via Google Colab on devices as portable as a smartphone. Users are encouraged to engage actively, bringing their own ideas to the table by opening issues or contributing via pull requests.
