TI  - Detection of outbreaks from time series data using wavelet transform.
PG  - 748-52
AB  - In this paper, we developed a new approach to detection of disease outbreaks 
      based on wavelet transform. It is capable of dealing with two problems found in 
      real-world time series data, namely, negative singularity and long-term trends, 
      which may degrade the performance of current approaches to outbreak detection. To 
      test this approach, we introduced artificail disease outbreaks and negative 
      singularities into a real world dataset and applied it and two other 
      algorithms-autoregressive (AR) and Multi-resolution Wavelet Auto-regressive 
      (MWAR) - to this dataset. We compared the performance of these algorithms in 
      terms of sensitivity, specificity and timeliness. The results showed that our 
      approach had similar sensitivity and specificity and slightly better timeliness 
      compared to the other two algorithms. When we introduced negative singularities, 
      its performance did not degrade as much as the other two algorithms' performance. 
      We conclude that our approach to detection, when compared to traditional 
      approaches, may not be as susceptible to degradation of performance caused by 
      negative singularities.
