I would like to use the Singular Value Decomposition before cluatering process. I will be thankfull if anyone has used this before, Is it a good idea for clustering? Is there any other method in mahout to reduce the text features before clustring? Is anyone has idea how can I apply SVD by using Java code? Thanks in advance, Donni --089e0103e4ce848bc505127c9433--
