Ok, apparently this message got through, so that answers my question.
Here is my original messages.
Sorry for the confusion.



Good Night Everybody,

I just looked at the documentation for the K-Means vector quantization
functions and I am a bit confused. On the one hand it says that
normalization to unit variance would be beneficial on the other hand
there are a lot of "must"s in the descriptions.
I was wondering if it is possible to use the functions without
normalization or if there is a negative impact.

This would make sense because it seems reasonable that one would want to
build the codebook on some set and then quantize a different set. In
this case normalization would have to be the same or be omitted.

I am also interested in literature recommendations concerning why this
is a good idea in general.

Any help would be greatly appreciated.

Best
Simon
