I think I took a quick look and didn't find any indication of such. If a significant application area of mahout is text, sparsity is a must. Even non-text domains, such as collaborative filtering, often require sparse representation in order to scale to medium-sized data sets. But, yeah, understood that it's good to hit the ground running, see how far we can get and make changes as necessary/useful :) > Read only access is available via: > svn co http://svn.apache.org/repos/asf/lucene/mahout/trunk > Thanks.
