Temporal Predictive Analytics
A fuzzy complex event processing (CEP) system successfully processing noisy, incomplete, multi-source data in support of near real-time decision-making. The fuzzy CEP solution of the present invention supports decision-making by identifying and exploiting patterns hidden in complex data and can operate in a forensic mode against historical data, near real-time mode for proactive decision-making, or any combination thereof. Fusion algorithms and techniques are applied to observation data that may only partially satisfy an event description in time, space, or other relevant dimensions. Using context propagation, Bayesian reasoning, and spatiotemporal analysis, the present invention provides both predictive awareness of upcoming events and likelihood analysis for events that may have already occurred, but were not evident in the collected data, while at the same time minimizing false detections.
