Abstract

A system for detecting change in a data stream comprising a distribution maintenance engine, a difference determining means and an alert generation engine is disclosed. The system detects change in the alert stream by the distribution maintenance engine maintaining a short term distribution that models the data stream and maintaining a long term distribution that models the data stream. The difference determining means determines the difference between the short term distribution and the long term distribution. The alert generation engine applies a statistical measure to the difference and generates an alert if the measure of the difference exceeds a threshold.
