Webthe energy of the time series can be represented by only a few wavelet coefficients. Moreover, if we use a spe-cial type of wavelet called Haar wavelet, we can achieve O(mn) time complexity that is much efficient than DFT. Chan and Fu used the Haar wavelet for time-series classifi-cation, and showed performance improvement over DFT [9].
