About

Statistics, Machine Learning, Data Science, and AI seem like very scary topics, but since each technique is really just a combination of small and simple steps, they are actually quite simple. My goal with StatQuest is to break down the major methodologies into easy-to-understand pieces. That said, I don't dumb down the material. Instead, I build up your understanding so that you are smarter. Contact, Video Index, Etc: https://statquest.org

Video Description

Reinforcement Learning is one of the most useful methodologies for training AI systems right now, and, while it might seem intimidating, is actually very similar to how you and I learn. This StatQuest cuts through the hype and helps you learn the essential concepts behind reinforcement learning one step at a time.
