## 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.
