Dmitriy Lyubimov commented on MAHOUT-1682:
------------------------------------------
http://mahout.apache.org/users/dim-reduction/ssvd.page/SSVD-CLI.pdf
it has a paragraph of why brute-force PCA is difficult in context of sparse
inputs. It is devoted to both SSVD and SPCA, albeit their MR versions. but
motivation and parameter treatment is the same.
> Create a documentation page for SPCA
