Subject how to run PCA from Mahout
Date Tue, 06 Sep 2011 12:33:46 GMT
Hi,
  It is mentioned on the web site : https://cwiki.apache.org/confluence/display/MAHOUT/Algorithms
  That you implement the following algorithms within Mahout :
     Gaussian Discriminative Analysis 
    Independent Component Analysis 
   Principal Components Analysis 

But unfortunately, I could not find any help or documentation  on how to use these algorithms!!

specially  I would like to try PCA on a huge data set of ~10Million vectors of 400 components
each.

Please give me some help on how to run PCA (and also ICA, GDA) whatever available.

Best regards,
Amr
