An algorithm of single component prediction based on backward error propagation is proposed, in which only one component concentration in a multivariate system is predicted each time. The algorithm was compared with a multiple component prediction model. In general, the predictive accuracy of the si

✦ Synopsis
The model parameters in artiÐcial neural networks have a great inÑuence on the training speed. It can be increased after choosing the optimum parameters, which was performed by a stepping technique. The training speed using the method is usually faster than that when adopting random or empirical parameters. An artiÐcial neural network model was used in multivariate matrix calibration and compared with cross-validation and partial least-squares methods, which were combined with the fundamental-parameters in x-ray Ñuorescence analysis. The results show that the artiÐcial neural network model produced the highest accuracy.

An empirical method is proposed for the correction of spectral interference between characteristic lines in XRF. The procedure is based on a coefficient which includes instrumental parameters and atomic properties and is obtained with the same standards as those used in calibration. This method has
