      spectrometry and least squares support vector machines].
PG  - 2471-4
AB  - Near-infrared spectroscopy (NIRS) combined with least squares support vector 
      machines (LS-SVM) was used to establish a new method for the determination of the 
      hesperidin content in guogongjiu medicinal wine. Firstly, training set was 
      partitioned by Kernard-Stone (KS) algorithm. Secondly, spectral pretreatment 
      methods were discussed in detail, comparing smoothing, rangescaling, autoscaling, 
      first derivative, second derivative, along with those methods combined. 
      Smoothing, first derivative and rangescaling were used for the pretreatment of 
      the NIR spectra of guogongjiu medicinal wine. Thirdly, the effective interval was 
      selected for 8211-8312 and 9712-9808 cm(-1) by synergy interval partial least 
      squares (siPLS). Finally, the model was established by LS-SVM, the root mean 
      square error of cross validation (RMSECV) is 0.001, root mean square error of 
      prediction (RMSEP) is 0.004, and relative deviation of predicting set is less 
      than 5%. It was compared with siPLS, radial basis function neural network 
      (RBF-NN), and SVM, The result shows that the method is rapid, non-destructive, 
      and credible. It is an effective measurement for determining the hesperidin 
      content in guogongjiu medicinal wine.
