Decision Trees Algorithm in Machine Learning

The Decision Tree Algorithm in machine learning is a supervised learning technique used for classification and regression tasks. It mimics human decision-making by breaking down a dataset into smaller subsets based on specific conditions, creating a tree-like model with nodes, branches, and leaves. Given your preference for step-by-step mathematical solutions, let’s walk through the complete process of constructing a decision tree, including entropy, information gain, and prediction testing.

Key Components of a Decision Tree
Root Node: The starting point, representing the entire dataset.
Internal Nodes: Decision points based on feature values.
Leaf Nodes: Final predictions or outcomes.
Branches: Paths representing feature-based decisions.
Key Concepts
Entropy: Measures impurity or randomness.
Information Gain: Reduction in entropy after splitting.
Gini Impurity: Another measure of impurity (often used in CART).
