"""Alternating least squares is often used to resolve components
|
|
contributing to data with a bilinear structure; the basic
|
|
technique may be extended to alternating constrained least squares.
|
|
Commonly applied constraints include unimodality, non-negativity,
|
|
and normalization of components. Several data matrices may be
|
|
decomposed simultaneously by assuming that one of the two matrices
|
|
in the bilinear decomposition is shared between datasets."""
