📗 Find or draw a decision tree. The decision tree can be created based on a dataset or a flow chart for a task or just a meme. Share an image on Piazza, and explain whether it is a regression tree, a classification tree, or neither. Also write down the output variable and list some of the input features.
📗 A regression tree is a decision tree that has continuous-valued labels, i.e. \(y \in \mathbb{R}\). A classification tree has discrete-valued labels, i.e. \(y \in \left\{1, 2, ...\right\}\).
📗 A tree that is neither a regression tree or a classification tree can be one describing a extensive form game (single-person or multiple-players). Technically, these are not decision trees and we will talk about game theory near the end of the semester, for now, you can read its Wikipedia page: Link.
