Temporal-Spatial Surveillance Techniques from Non-Homogenous Random Geometric Graphs
Content Type: Abstract
Graph theory concepts are well established in epidemiology, with particular success as a description of agent-based modeling. An agent-based viewpoint leads to conclusions about the spatial distribution of links: infection is more likely among… read more -
Detecting Coherent Structures in Syndromic Time Series Using Wavelets
Content Type: Abstract
Temporally localized outbreaks occur in the presence of a complex background, greatly complicating both retrospective and real-time detection. Numerous techniques have been proposed for adjusting thresholds to account for this variable background.… read more -
Benchmarking Temporal Surveillance Techniques
Content Type: Abstract
Benchmarking of temporal surveillance techniques is a critical step in the development of an effective syndromic surveillance system. Unfortunately, holding “bakeoffs” to blindly compare approaches is a difficult and often fruitless enterprise, in… read more -
Characterizing Repeated Outbreak Patterns in Influenza Time Series
Content Type: Abstract
In some influenza seasons, morbidity and mortality closely follow the expected seasonal variation. In these years, approaches such as SerflingÃs model and seasonal-based syndromic outbreak detectors, in use in EARS, work well. In other years,… read more
