Classification using Decision Trees

Play an AI-generated podcast conversation about this lesson

What is the main purpose of a decision tree in the context of classification and regression tasks?

To identify areas of similar land use

To group similar objects into classes or clusters

To create a hierarchical tree structure

To predict the class or value of a target variable based on input features (correct)

In the given car insurance applicants example, what is the class being predicted?

Family

Risk (correct)

Car type

Age

What is the main difference between decision trees and clustering?

Decision trees are used for image processing, while clustering is used for marketing

Decision trees are unsupervised learning techniques, while clustering is supervised

Decision trees predict the class or value of a target variable, while clustering groups similar objects into classes (correct)

Decision trees require labeled datasets, while clustering does not
