Hj. Luinge et al., PARTIAL LEAST-SQUARES REGRESSION AS A MULTIVARIATE TOOL FOR THE INTERPRETATION OF INFRARED-SPECTRA, Chemometrics and intelligent laboratory systems, 28(1), 1995, pp. 129-138
The potentials of partial least squares regression (PLS) as a tool for
the automated interpretation of infrared spectra have been investigat
ed. Class probabilities are obtained by applying a sigmoid function to
the PLS predictions. Results are compared with those obtained from ar
tificial neural networks (ANN) applied to full spectra and to the most
relevant principal component scores. The predictions obtained from al
l approaches appear to be comparable, but the time required for traini
ng is considerably shorter for the extended PLS approach.
