Claim 11:
12. An apparatus for generating a combined Isolation Forest model for detecting anomalies in data, the apparatus comprising:
an input interface configured to:
receive 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; and
receive 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; and

a processing circuit configured to
search for redundancies in the first plurality of trained decision trees and the second plurality of trained decision trees,
remove found redundancies from the first plurality of trained decision trees and the second plurality of trained decision trees, and
combine the first Isolation Forest model and the second Isolation Forest model to obtain the combined Isolation Forest model.
