I've done a version of nipals algorithm in python (i'ts a translation of
a matlab routine in brereton made by Riccardo Leardi). far from perfect
(my transport i mean) but working (I've tested on my datasets and it
runned ok) you can download it at www.chemometrics.it.
Hope it will help and if yo
Except last I checked numpy.linalg doesn't have an efficient method for
retrieving only a few PCA components.
So yeh, you can do PCA but it will be *really* slow on most of the types of
problems that PCA is usually used for.
You need something like an ARPACK wrapper, which I think they have in the
Hi,
You have everything you need for PCA in numpy.linalg.

I'm doing some projects in Python (system GNU / Linux - Ubuntu 7.0) about
image processing. I'm needing a implementation of PCA, prefer to library for
apt-get.
Thanks.
