ALS

Multivariate Curve Resolution Alternating Least Squares (MCR-ALS)

v0.0.7 · Aug 25, 2022 · GPL (>= 2)

Description

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.
