[hts-users:03324] Re: About the prototype definition of the MSD-HMM

[Kwan Lisa <lisakwan1102@xxxxxxxxx>]

Hi,

I don't understand why the distributions of frequency and its 1- and
2-order dynamics are placed in stream 2, 3, and 4 respectively, but
the distributions of spectral and its 1- and 2-order dynamics are
placed in stream 1. What if I place all of frequency feature in stream
2 and treat them as a 3 dimensional data like spectral data?
