Anomaly Pattern Detection for Biosurveillance
Content Type: Abstract
We propose a new method for detecting patterns of disease cases that correspond to emerging outbreaks. Our Anomaly Pattern Detector (APD) first uses a "local anomaly detector" to identify individually anomalous records and then searches over subsets… read more… GI). In order to determine if the subset of the test data cor- responding to rule R has an unexpectedly high con- centration of anomalies, we compare it to the corres- … Further Information: Daniel B.

Discriminative Random Field Approach to Spatial Outbreak Detection
Content Type: Abstract
Spatial scan finds the most anomalous region that has shown increase in observed counts when compared to the expected baseline. As there can be infinitely many regions to search for, most state-of-the-art algorithms assumes a… read more… area is repre- sented by a node. Two nodes in the DRF are con- nected if they share a common boundary. The ob- served …
