Decision trees - A friendly introduction

View ChannelAbout
Welcome to Serrano.Academy! I'm Luis Serrano and I love demystifying concepts, capturing their essence, and sharing these videos with you. I prefer illustrations, analogies, and cartoons, rather than formulas (although we don't shy away from the math when needed). The topics I have are machine learning, mathematics (probability and statistics), but I'm open to many others. If you have any topics you'd like to suggest, feel free to add them in the comments or drop me a line! For more information, check out http://serrano.academy. And also check out my book!
