| Résumé : |
In recent years artificial neural networks(ANN) have generated widespread interest and gained popularity.Numerous applications have been investigated, including pattern recognition,signal processing, process control and modeling or calibrating. ANN as a nonlinear calibraion method has been found to give superior results in calibration of nonlinearly behaving solutions.In the present study neural networks are applied to multivariate calibration of dye solutions using spectroscopic data and for producting quantitative estimates of the concentrations of a component in the mixture.Absorbance is linearly dependent on concentration only in a narrow concentration range.There exists severe overlapping of the absorption bands in multi-component dye solutions. The solutions studied here were multi-component and the concentration range of the dye to be calibrated was wide(0-975 mg/l). Thus the absorbance of the solutions changes nonlinearly as a fonction of concentration.The results are compared with the results obtained with other multivariate calibration methods; principal component regression ans partial least-squares regression. Metal complex dyes were used in making the dye solutions.The absorbance spectra of the samples were measured in the visible range of light. The sigmoid output function was used in the hidden layer of the network to perform nonlinear fitting. |
