This paper introduces and describes an alternative clustering approach based on the discrete wavelet transform (DWT) which satisfies requirements that other clustering methods, like discriminative-based clustering and model-based clustering approaches, do not satisfy. The clustering method has...

This paper describes a new approach to analys the Fractional Difference (FD) processes using spectral analysis. The approach is based on the periodogram and the main idea behind it is to divide the Fourier frequencies into different frequency intervals or bands, matching the band-pass of the...
