Textbook

I have been working on a textbook on reinforcement learning started from when I taught the new Introduction to Reinforcement Learning course in Spring 2021. The current version is from 2021. I am hoping to have a major update in 2025.

• A.M. Farahmand, Lecture Notes on Reinforcement Learning, 2021.

  The textbook is introductory in the sense that it does not assume prior exposure to reinforcement learning. It is not, however, focused on being a collection of algorithms or only providing high-level intuition. Instead, it tries to build the mathematical intuition behind many important ideas and concepts often encountered in RL. We prove many basic, or sometimes not so basic, results in RL. If the proof of some result is too complicated, we prove a simplified version of it.

  If you are a university instructor and wish to use slides for your own course, please contact me.
