Abstract: Simultaneous determination of the multicomponents of four B-group vitamins with a novel Linear Neural Network (LNN) algorithm was reported. Based on the data correlation coefficient and standard deviation, 11 representative wavelength points were selected from the original UV spectral data (240 points) as the original input patterns for FLN to build an NN model. The results obtained by LNN is satisfactory, with a correlation coefficient 0.999 83 and a standard deviation 0.113 01.

Key words: Linear neural network (LNN), Kalman filtering, Multicomponent simultaneous determination, Four B-group vitamins
