Abstract:
A system for generating an alert from data obtained from a process, comprising:a normalizer for normalizing the data; a classifier for classifying the normalized data in a multi-dimensional space defined for a plurality of variables in the process, the normalized data classified into a normal class or an abnormal class defined in the multi-dimensional variable space, wherein the normal class is indicative of normal operating conditions for the process and the abnormal class is indicative of potential alert conditions in the process; an alert level evaluator for evaluating a vigilance level of the classified data for related variables, said alert level evaluator increasing the vigilance level following a suspicious data reading data classified in the abnormal class and decreasing the vigilance level following a data reading classified in the normal class; and an alert score generator for generating an alert score for each of the related variables according to the vigilance level.
