ANOMALY DETECTION SYSTEM

Aspects of the present invention disclose a method and system for anomaly detection for a data source. The method includes one or more processors identifying unexpected values of monitoring measurands in a monitored time series utilizing an anomaly detection algorithm. A data source provides sensor data, including values of a first group of measurands, which include monitoring measurands. The method further includes determining that values of a second group of one or more of the measurands of a subset of sensor data indicates an anomaly utilizing the anomaly detection algorithm. The method further includes sending anomalous data indicative of the subset of sensor data to a root cause analysis system and receiving corresponding feedback that is indicative of a result of a root cause analysis of the subset of sensor data and comprises a third group of the measurands. The method further includes adapting the anomaly detection algorithm.
