摘要:

本文建立了一个基于BP人工神经网络的手部气味识别模型,并对网络参数进行了选择优化。人体手部气味经样品采集、浓缩后,用气相色谱质谱联用仪对其进行分析获得手部气味轮廓图,并利用逐步判别分析法提取了手部气味轮廓图的47个特征变量(有机化合物)。在此基础上,构建了一个47 × 10 × 1BP网络,其隐含层和输出层的传递函数分别为tansiglogsig,训练函数为trainrp。该网络能正确区分不同性别的手部气味。

A recognition model has been developed based on Back Propagation Artificial Network and its net parame- ters were optimized. Hand odors were sampled, concentrated and then analyzed with Chromatography-Mass Spectrometer, resulting in hand odor profiles whose feature variables (47 organic compounds) were extracted and reduced by means of stepwise discriminant analysis. In sequence, a BP network, in which the structure was 47 × 10 × 1, the transfer functions for hidden layer and output layer tansig and logsig, respectively, and the training function trainrp, was pro- posed. The experiment demonstrated that the network was able to specify whether an odor sample had been from man hand or woman hand.
