IsolationForest is a class in the sklearn.ensemble module of Python's scikit-learn library. It is an anomaly detection algorithm that uses the concept of isolation to identify outlier data points. It creates a forest of random decision trees and isolates anomalies by assigning them shorter paths in the tree structure. IsolationForest is useful for detecting anomalies in datasets that have a majority of normal observations, making it a valuable tool for fraud detection, network intrusion detection, and other similar applications.
