Q: What is the Gini impurity used for in Decision Trees?
Solution:
Gini impurity is used to determine the best split at each node in a Decision Tree, helping to create more homogeneous child nodes.
Steps: 6
Show Steps
Step 1: Understand that a Decision Tree is a model used for making decisions based on data.
Step 2: Know that each point in the tree is called a node, where decisions are made.
Step 3: Realize that we want to split the data at each node to make the groups (child nodes) more similar to each other.
Step 4: Learn that Gini impurity is a measure that helps us see how mixed or pure the groups are after a split.
Step 5: Use Gini impurity to calculate how well a split separates the data into different classes.
Step 6: Choose the split that has the lowest Gini impurity, meaning the child nodes will be more homogeneous.
