A Case Manager Tool for Anomaly Investigation in BioSurveillance
Content Type: Abstract
Effective anomaly detection depends on the timely, asynchronous generation of anomalies from multiple data streams using multiple algorithms. Our objective is to describe the use of a case manager tool for combining anomalies into cases, and for… read more… of New Jersey include some 4.2 million records for ED visits to 24 hospitals in the New Jersey and New York, for the years 1996-2005. The record for each visit includes hospital, patient geography … the meningitis scare, the “Clinton” chest pain effect, ED visits related to possible anthrax exposure around October … -
An Adaptive Anomaly Detection Algorithm
Content Type: Abstract
Ideal anomaly detection algorithms shoulddetect both sudden and gradual changes, while keeping the background false positive alert rate at a tolerable level. The algorithms should also be easy to use. Our objective was to develop an anomaly… read more… C2 or C3 alert.
