In one embodiment, a computer-implemented method includes observing one or more entities by way of two or more data sources. A plurality of detection scores are computed by one or more detectors. Each detection score corresponds to an entity of the one or more entities, a detector of the one or more detectors, and a time. The plurality of detection scores are compiled into two or more tensors, where each tensor corresponds to a data source of the two or more data sources. The two or more tensors are compared to one another, by a computer processor. An inconsistency score is calculated for each of the one or more entities, based on comparing the two or more tensors to one another.
