Decision and Classification Trees, Clearly Explained!!!
Показать описание
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 asked about the old one.
Note, you may also want to learn about...
For a complete index of all the StatQuest videos, check out:

...or...
...a cool StatQuest t-shirt or sweatshirt:
...buying one or two of my songs (or go large and get a whole album!)
...or just donating to StatQuest!
Lastly, if you want to keep up with me as I research and create new StatQuests, follow me on twitter:
0:00 Awesome song and introduction
0:18 Basic decision tree concepts
3:16 Building a tree with Gini Impurity
9:15 Numeric and continuous variables
12:35 Adding branches
13:56 Adding leaves
14:32 Defining output values
15:12 Using the tree
15:38 How to prevent overfitting
