Update set of characteristics based on region

摘要

An object may be identified, if each measured value of a characteristic of the object is within a corresponding range of a set of characteristics. The object may then be classified as a true alarm or false alarm by a user. Next, the measured values of the object may be added as a data point to a set of data points. Each of data points is along a plurality of dimensions and each of the dimensions corresponds to one of the set of characteristics. Further, each of the data points has been classified as a true alarm or false alarm.;The range of the set of characteristics may be updated to reduce a weighted score based on a number of the true alarms that are outside a region along the plurality of dimensions and a number of the false alarms inside the region for the set of data points. The region is defined based on numerical analysis of the set of data points. The weighted score may provide separate weights to the true alarms outside the region and the missed alarms inside the region.
