A System for Simulation: Introducing Outbreaks into Time Series Data
Content Type: Abstract
Objective Several authors have described ways to introduce artificial outbreaks into time series for the purpose of developing, testing, and evaluating the effectiveness and timeliness of anomaly detection algorithms, and more… read more… the efficiency of using time series data several fold com- pared to when just a single artificial outbreak is … -
HWR at the Contest: A Holt-Winters-Based Method Applied to Simulated Outbreaks
Content Type: Abstract
Objective: Ideal anomaly detection algorithms should detect both sudden and gradual changes, while keeping the background false positive alert rate at a tolerable level. Our objective was to develop an anomaly detection algorithm that adapts to the… read more… sev- eral different criteria [1]. The anomaly detection con- test required a continuous score for each day of the … all the test series for this fixed alert threshold. The col- umn “maximum number of false positives in 5 years” … -
Talking Turkish: Using N-Grams for Syndromic Surveillance in a Turkish Emergency Department without the Need for English Translation
Content Type: Abstract
Previously we used an “N-Gram” classifier for syndromic surveillance of emergency department (ED) chief complaints (CC) in English for bioterrorism. The classifier is trained on a set of ED visits for which both the ICD diagnosis code and CC are… read more… English Translation Sylvia Halasz PhD1, Philip Brown1, Cem Oktay MD2, Arif Alper Cevik MD3, Isa Kilicaslan MD2, … -
Sensitivity and Specificity of an Ngram Method for Classifying Emergency Department Visits into the Respiratory Syndrome in the Turkish Language
Content Type: Abstract
Previously we developed an “Ngram” classifier for syndromic surveillance of emergency department (ED) chief complaints (CC) in Turkish for bioterrorism. The classifier is developed from a set of ED visits for which both the ICD… read more… Syndrome in the Turkish Language Philip Brown1, Cem Oktay MD2, Arif Alper Cevik MD3, Isa Kilicaslan MD2, …
