Presentation / Conference
Bagnall, A. J., Whittley, I. M., Janacek, G. J., Kemsley, K., Studley, M., & Bull, L. (2006, June). A comparison of DWT/PAA and DFT for time series classification. Paper presented at International conference on Data Mining (DMIN '06), Las Vegas, US

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 tran...
