Classification: CPC G | IPC G

Claim 13:
14. A system comprising:
a first electronic device comprising a first processing circuit configured to train a first Isolation Forest model for detecting anomalies in data;
a second electronic device comprising a second processing circuit configured to train a second Isolation Forest model for detecting anomalies in data; and
a third electronic device comprising:
an input interface configured to receive the first Isolation Forest model from the first electronic device and the second Isolation Forest model from 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;
a third 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 a combined Isolation Forest model; and

an output interface configured to transmit the combined Isolation Forest model to the first electronic device and the second electronic device,

wherein at least one of the first processing circuit and the second processing circuit is configured to analyze data at the respective electronic device for anomalies using the second Isolation Forest model.
