Decision trees

In this section, we will be using decision trees and student performance data to predict whether a child will do well in school. We will use the previous techniques with some scikit-learn code. Before starting with the prediction, let's just learn a bit about what decision trees are.

Decision trees are one of the simplest techniques for classification. They can be compared with a game of 20 questions, where each node in the tree is either a leaf node or a question node. Consider the case of Titanic survivability, which was built from a dataset that includes data on the survival outcome of each passenger of the Titanic.

Consider our first node as a question: Is the passenger a male? If not, then the passenger most likely survived. ...
