Question: What does pruning refer to in the context of Decision Trees?

Options:

Correct Answer: Removing nodes to reduce complexity

Solution:

Pruning refers to the process of removing nodes from a Decision Tree to reduce its complexity and prevent overfitting.

What does pruning refer to in the context of Decision Trees?

Step 1: Understand that a Decision Tree is a model used for making decisions based on data.
Step 2: Know that sometimes Decision Trees can become too complex by having too many branches or nodes.
Step 3: Realize that this complexity can lead to overfitting, which means the model performs well on training data but poorly on new data.
Step 4: Pruning is the process of simplifying the Decision Tree by removing some of these branches or nodes.
Step 5: The goal of pruning is to make the Decision Tree simpler, more general, and better at predicting new data.
