Hello Luca,
This was a problem that even I had noticed quite recently. It does seem
that the normalize option does not scale the input data to unit variance
(or) standard deviation. For some reason the data is scaled to square root
of n_samples.
Attempts were made to rectify this but there were too many test failures.
Please see this Pull Request.
