What is Decision Tree?
Decision Tree
A Decision Tree is a non-parametric supervised learning method used for both classification and regression. The goal is to create a model that predicts the value of a target variable by learning simple decision rules inferred from the data features.
Why It Matters for AI Builders
Helps AI builders design and scale robust architectures; mastering the implementation of Decision Tree improves latency, accuracy, and operational efficiency for customer churn prediction, medical diagnosis tree diagrams, and baseline classification.
Detailed Deep Dive
A decision tree is a non-parametric supervised learning algorithm used for both classification and regression tasks. It structures decisions in a flowchart-like tree structure, where each internal node represents a test on an input feature, each branch represents the outcome of the test, and each leaf node represents a class label or a continuous value. Decision trees are highly interpretable, but they are prone to overfitting unless pruned or combined into ensemble methods like random forests.
Frequently Asked Questions
Q:What is a node in a decision tree?
A split condition based on a feature value. The leaves represent final target outcomes or classifications.
Q:What is the main drawback of decision trees?
They are highly prone to overfitting the training data, which is typically resolved by pruning the tree or using random forests.
