Claim 0:
1. A method for generating a combined Isolation Forest model for detecting anomalies in data, the method comprising:
receiving a first Isolation Forest model for detecting anomalies in data from a first electronic device, wherein the first Isolation Forest model is trained at the first electronic device;
receiving a second Isolation Forest model for detecting anomalies in data from a second electronic device, wherein the second Isolation Forest model is trained at the second electronic device;
wherein the first Isolation Forest model represents a first plurality of trained decision trees, and wherein the second Isolation Forest model represents a second plurality of trained decision trees,
searching for redundancies in the first plurality of trained decision trees and the second plurality of trained decision trees;
removing found redundancies from the first plurality of trained decision trees and the second plurality of trained decision trees; and
combining the first Isolation Forest model and the second Isolation Forest model to obtain the combined Isolation Forest model.
