| 英文摘要 | Nir technology is a rapid, nondestructive and user-friendly method ideally suited for qualitative analysis. in this paper the authors present the use of discriminant partial least squares (dpls)-based linear discriminant analysis (lda) in corn qualitative near infrared spectroscopy analysis. firstly, a training set including 30 corn varieties (each variety has 20 samples) was used to build the dpls regression model, and 28 principal components (dpls-pcs) were obtained from original spectrum. secondly, the dpls-pcs scores of the training set were extracted as dpls features. thirdly, lda was applied to the dpls features, determining 26 principal components (lda-pcs). a test sample was first projected onto the dpls-pcs and then onto the lda-pcs, and finally 26 dpls+lda features were obtained. the recognition results were obtained by minimum distance classifier. dpls+lda method achieved 96. 18% recognition rate, while traditional dpls regression method and dpls feature extraction method only achieved 85. 38% and 95. 76% recognition rate respectively. the experiment results indicated that dpls +lda method is with better generalization ability compared with traditional dpls regression method and nirs analysis by dpls+lda method is an efficient way to discriminate corn species. |
