Alternative Quality Measures for Time Series Shapelets

  title={Alternative Quality Measures for Time Series Shapelets},
  author={Jason Lines and Anthony J. Bagnall},
Classification is a very broad and prevalent topic of research within data mining. Whilst heavily related, time series classification (TSC) offers a more specific challenge. One of the most promising approaches proposed for TSC is time series shapelets. In this paper we assess the current quality measure used for shapelet extraction and introduce two statistical tests into the context of shapelet finding. We show that when compared to information gain, these two quality measures can speed up… CONTINUE READING
