What is a Decision Tree?

In this ninth class of the Artificial Intelligence course, the instructor reviews previous lessons on machine-learning models and introduces decision trees. Decision trees are explained as tree-like structures that help make decisions through a series of questions. An example is provided to predict whether a car has a low or high range based on its weight and number of cylinders. The decision tree process is detailed, showing how different conditions lead to different outcomes.

What are decision trees and how do they function in making decisions?

Describe the process of predicting a car's range using a decision tree.

What initial question do we ask when using a decision tree to determine a car's range?

Explain the outcomes based on the weight and number of cylinders of a car according to the decision tree.

How can we determine the range of a new car using the decision tree model?
