In this StatQuest we explain how AI, like ChatGPT, works. However, instead of using lots of complicated math, we're going to use a super simple example and super simple terms. If math scares you, this StatQuest is for you! And even if math doesn't scare you, this StatQuest will give you a deeper understanding of what goes on under the hood. BAM!
