Random Forests

[ˈrændəm ˈfɔrəsts]
Machine Learning
Last updated: December 9, 2024

Definition

An ensemble learning method that combines multiple decision trees to improve prediction accuracy.

Detailed Explanation

Random Forests build multiple decision trees using bootstrapped datasets and random feature selection. The ensemble's prediction is typically the mode (classification) or mean (regression) of the individual trees, enhancing performance and reducing overfitting. The algorithm uses random subsets of features and bootstrap samples of data, making it effective for feature selection and handling large datasets with missing data.

Use Cases

Classification and regression tasks feature importance ranking handling large datasets dealing with missing data.
