Intelligent alarm classification based on DSmT
Albena Tchamova, Jean Dezert · 2012
In this paper the critical issue of alarms' classification and prioritization (in terms of degree of danger) is considered and realized on the base of Proportional Conflict Redistribution rule no.5, defined in Dezert-Smarandache Theory of plausible and paradoxical reasoning. The results obtained show the strong ability of this rule to take care in a coherent and stable way for the evolution of all possible degrees of danger, relating to a set of a priori defined, out of the ordinary dangerous directions. A comparison with Dempster's rule performance is also provided. Dempster's rule shows weakness in resolving the cases examined. In Emergency case Dempster's rule does not respond to the level of conflicts between sound sources, leading that way to ungrounded decisions. In case of lowest danger's priority (perturbed Warning mode), Dempster's rule could cause a false alarm and can deflect the attention from the existing real dangerous source by assigning a wrong steering direction to the surveillance camera.
