May 1, 2024 Updated May 11, 2025 20 minute read

Random Forests represent a powerful and versatile supervised machine learning algorithm. At a high level, a Random Forest is an ensemble learning method that operates by constructing a multitude of decision trees during its training phase and outputting the class that is the mode of the classes (classification) or mean prediction (regression) of the individual trees. This technique is widely recognized for its ease of use and its ability to often produce strong results even without extensive hyperparameter tuning.

Working with Random Forests can be engaging due to their inherent ability to handle complex datasets with numerous variables, a common scenario in fields like finance and healthcare. The algorithm's capacity to determine the importance of different features in making a prediction offers valuable insights into the underlying data. Furthermore, the robustness of Random Forests against overfitting, a common pitfall for individual decision trees, makes it a reliable choice for many predictive modeling tasks.
