Spectroscopy is an important component analysis method and full spectrum prediction method may be complicated and inaccurate. In order to find out the irrelevant variables, a variable selection method based on the frequent pattern tree(FP-tree) is proposed in this paper. The proposed method firstly formulates an orthogonal array to generate wavelength selection plans, which makes the wavelength selection...
Spectroscopy has been widely used to evaluate product quality or to predict components. To deal with the nonlinearity of spectral data, artificial neural networks (ANN) are widely used. One weakness of ANN is we have no accurate analytical method to design a optimal network structure. A multivariate component prediction method based on optimized neural network combined with evolutionary algorithm...
