Decision trees are part of the foundation for Machine Learning. Although they are quite simple, they are very flexible and pop up in a very wide variety of situations. This StatQuest covers all the basics and shows you how to create a new tree from scratch, one step at a time.
NOTE: This is an updated and revised version of the Decision Tree StatQuest that I made back in 2018. It is my hope that this new version does a better job answering some of the most frequently asked questions people…

The big drawback to refreshable braille devices has always been their cost. The loose rule of estimation applied to these products has translated into something like $100 to $150 per braille cell. A 40-cell display, in other words, may cost $4,000 to $6,000, while an 80-cell model will cost $8,000 to $12,000. And so…

Ever noticed that parks are cooler than streets on hot days? Different surfaces absorb heat differently. In this science project, we'll use temperature and satellite data to identify urban heat islands in a city and investigate how surface types affect temperature.
