21. A data processing system for validating expected cohort behavior comprising: a sensory data processing engine, wherein the sensory data processing engine receives sensory data associated with a cohort group from a plurality of multimodal sensor devices and wherein the sensory data processing engine processes the sensory data to form a set of actual cohort behavior data; a cohort behavior comparison component, wherein the cohort behavior comparison component compares the set of actual cohort behavior data to a set of predicted cohort behavior models, wherein the set of actual cohort behavior data comprises information describing actual behavior by members of the cohort group and wherein the set of predicted cohort behavior models comprises information describing an expected behavior of members of the cohort group, and wherein the cohort behavior comparison component generates a comparison result, wherein the comparison result indicates an accuracy of the set of predicted cohort behavior models.

The data processing system of claim 21 wherein the sensory data processing engine further comprises: a video analysis system, wherein the video analysis system analyzes a stream of video data received from at least one digital video camera in the set of multimodal sensors, wherein the video analysis system generates metadata describing contents of the stream of video data, and wherein the sensory data processing engine identifies events associated with behavior of cohorts using the metadata.
