A PARAFAC algorithm using penalty diagonalization error (PDE) for three-way data array resolution
Abstract
A modified parallel factors analysis (PARAFAC) algorithm with
the penalty diagnolization error (PDE) was developed. This algorithm can
overcome the slow convergence problem of the traditional PARAFAC method and
is insensitive to the number of components, i.e., it is much
faster than PARAFAC and insensitive to overestimation of the dimensionality
of the model. The characteristic performance was demonstrated by treating
simulated and real excitation–emission fluorescence data for samples
of
