Abstract
A device detects anomalies on an input stream of events. Each event includes a value. The device has: a modeling unit configured to represent each event into at least one histogram over a predefined tree data structure to obtain a model of the input stream; a change detection and adaptation module configured to detect a long term change of the distribution of the events in the input stream based on the model of the input stream; and a scoring unit configured to calculate an anomaly score representing the probability of an anomaly in the input stream of events based on the model of the input stream and the detected long term change.
