Abstract

Discrete Fourier transforms (DFT) and Haar two, PAA is identical to a Haar Wavelet transformation [61. wavelets (DWT) were proposed for the use in time series data mining over five years ago and have since proved to be popular algorithms for the transformation and compression of time dependent data, particularly for strawman comparisons to new...
