| 摘 要： | 用BP人工神经网络解析了VB1、VB2、VB6和VPP的紫外吸收光谱,提出同时测定这四种维生素的计算分析方法,并对复合维生素片中的VB1、VB2、VB6和VPP进行了同时测定,VB1、VB2、VB6和VPP平均相对误差分别为1.45%,1.57%,4.08%和1.87%.使用了改进的BP算法,避免了神经网络学习过程中可能产生的麻痹现象;提出了目标向量的简单变换方法.

| Abstract: | The ultraviolet spectra of VB_(1),VB_(2),VB_(6) and VPP have been analysed by ANN-BP algorithm. The method was applied to simultaneously determine VB_(1),VB_(2),VB_(6)and VPP in the tablet of compound VB, and relative mean errors of VB_(1),VB_(2),VB_(6) and VPP are 1.45%, 1.57%, 4.08% and 1.87% respectively. The paralysis in the procedure of training about ANN has been avoided by the improved back propagation algorithm. The simple transformation method for target vectors has been put forward. |
