Comparison of the training of neural networks for quantitative x-ray fluorescence spectrometry by a genetic algorithm and backward error propagation

Abstract: Neural networks are shown to be useful as emplncal mathematical models m the calculation of quantltatlve analytical results, gvmg sufflclent accuracy to compete successfully with various common cahbratlon procedures. The performance of these neural-network models for cahbratlon data from x-ray fluorescence spectrometry (XRF) was evaluated for two trammg methods, 1 e , backward error propagation (BEP) and a genetic algonthm (GA) For a small triumng set (13 members) of data from Fe/Nl/Cr samples taken from the h… Show more

“…Moreover, neural networks have gained attention in XRF. Bos 61 compared the results of x-ray fluorescence spectrometry by backward error propagation (BEP) and a genetic algorithm, based on data from Fe-Ni-Cr samples taken from the literature. For a small training set with 13 data members, the BEP model compared favorably with the traditional matrix correction models.…”

“…A PNN is predominantly a classifier that combines attributes of statistical pattern recognition and feed forward artificial neural networks [4]. In the past decade the ANN modeling technique has found applications for recognition and classification of spectra from a variety of spectroscopic methods [5][6][7][8][9]. Different network architectures, including a MLP, radial basis function (RBF), self-organizing map (SOM), and probabilistic neural network (pnn), have been proposed for classification purposes.…”
