  • 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
    … how common analytical development and analysis may be coupled with realistic data sets to provide insight … and then benchmarked using five years of daily visits in the Boston area of the HPHC data. In particular, … we dem- onstrate an approach for this process based on a com- mon analytical development and benchmarking with common …
  • 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 Serflingís model and seasonal-based syndromic outbreak detectors, in use in EARS, work well. In other years,… 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
