Optimizing a System of Threshold-based Sensors with Application to Biosurveillance

摘要

These briefing charts discuss biosurveillance, and goals, issues and results. The term biosurveillance means the process of active data gathering, of biosphere data, in order to achieve early warning of health threats, early detection of health events and overall situational awareness of disease activity. The goal is early detection of disease outbreak and/or bioterrorism. The issue is currently detection thresholds set naively; equally for all sensors, ignores differential probability of attack. The result is high false alarm rates, and loss of credibility.
