A general method of anomaly detection from time-correlated sensor data is disclosed. Multiple time-correlated signals are received. Their cross-signal behavior is compared against a fixed library of invariants. The library is constructed during a training process, which is itself data-driven using the...http://www.google.fr/patents/US6625569?utm_source=gb-gplus-shareBrevet US6625569 - Real-time spatio-temporal coherence estimation for autonomous mode identification and invariance tracking
