...ny clustering at all, or I have chosen the wrong
variables in the data set.
I'm somehow trying to cluster signal amplitudes that are not referred
to the same phase values. For instance, if I have two sinusoids
sampled at different phase values like:
{sin(0), sin(1/4PI), sin(3/2PI)} and {cos(1/8PI), cos(1/2PI), cos(5/2PI)}
is it meaningful to cluster the two set of values above or shall I
first refer both signals to the same phase in advance of clustering,
like:
{sin(0), sin(1/4PI), sin(3/2PI)} and {cos(0I), cos(1/4PI), cos(3/2PI)}
or:
{sin(1/8PI), sin(1/2PI), sin(5/2PI)} and {cos(1/8...
