The basic idea is calculating wavelet coefficients for each time series based on Haar wavelet transform. The first k coefficients are used to form a MBR. Thus, the point filtering method can be used. In addition, lower bounding and upper bounding features of each time series are calculated in advance, which are stored into index structure. Finally, triangle inequality pruning method is adopted by calculating the distance between time series beforehand.
