Reinforcement learning (RL) is gaining popularity again.

Thanks to this technique, we have seen some truly amazing recent inventions, such as Reasoning LLMs and Humanoid robots.

While many ML engineers are experts in Supervised learning, they lack confidence when working with RL. This is the reason why I’m writing my new visual learning book that makes RL concepts easy to grasp.

This book is a continuation of my efforts to make technology easy to learn and understand through visual learning.

The previous books in this visual tech learning series include:

  • AI In 100 Images (Free to download and read)

  • LLMs In 100 Images

  • Systems Design In 100 Images

  • Computer Science In 100 Images

While the book is still a work in progress, here are 10 images from it to help you get started with RL.
