## Intro
-Mahout has a distributed implementation of Stochastic PCA[1]. this algorithm
computes the exact equivalent of Mahout's `dssvd(` `\(\mathbf{A-1\mu}\)` `)` by
modifying the `dssvd` algorithm so as to avoid forming `\(\mathbf{A-1\mu}\)`,
which would densify a sparse input. Thus, it is suitable for work with both
dense and sparse inputs.
