The problem of variable selection for neural network modeling is discussed in this paper. Two methods that gave the best results in a previous comparative study are presented. One of these methods is a modified version of the Hinton diagrams, the other method is based on saliency estimation and is p

A comparative study to select calibration mixtures and wavelengths in multivariate calibration methods was made. The methods studied were classical least squares (CLS), inverse least squares (ILS), partial least squares (PLS), principal component regression (PCR) and Kalman filter. For each method t

The importance of the validation step in multiple linear regression of near-infrared spectroscopic data, after selection of wavelengths by a genetic algorithm, is investigated with the use of random variables. It is shown that in spite of a careful validation procedure, the GA can still select irrel

✍ Christopher D. Brown; Peter D. Wentzell πŸ“‚ Article πŸ“… 1999 πŸ› John Wiley and Sons 🌐 English βš– 180 KB

The efficacy of smoothing first-order data as a preprocessing method for multivariate calibration is discussed. In particular, the use of symmetric smoothing filters (such as Savitzky-Golay filters) is examined from the perspective of calibration performance, in contrast with past studies based on u
