The Chain Rule, Clearly Explained!!!
StatQuest with Josh Starmer
@statquestAbout
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
The Chain Rule is a method for finding complex derivatives and is used all the time in Statistics and Machine Learning. This video breaks it down into its two simple pieces and shows you how they easily come together. We then use the Chain Rule to solve a common Machine Learning problem - optimizing the Residual Squared Loss Function.

And when the residual is positive, the pink circle should be on the right side. #StatQuest #TheChainRule #DubbedWithAloud
