To achieve the fast discrimination of five varieties of honeys, namely linden honey, vitex honey, rape honey, acacia honey and litchi honey, we propose a new method in this article by using the mid-infrared spectra based on principle component analysis (PCA) combined with linear support vector machine (SVM) or least squares support vector machine (LSSVM). The mid-infrared spectra of five varieties of honey samples are determined by Fourier transform infrared spectroscopy and normalized. Then the 5-dimensional, 10-dimensional, 15-dimensional, and 20-dimensional feature data will be extracted from spectra with the use of dimension reduction method of PCA after normalization. Finally, the two classifier models, linear SVM and LSSVM with radial basis function (RBF) based on the grid search optimization, are designed. Using different classifier model, we identify the different dimensional feature data extracted from spectra data of unknown honey samples. Then the results of different dimension feature data and different support vector machines are validated. Experimental results show that for the 20-dimensional feature data obtained by the dimension reduction method of PCA, an average recognition rate of higher than 97% on SVM and LSSVM classifiers is achieved, the highest recognition rate can reach 100%, and classifier stability is very good. LSSVM classifier has higher recognition accuracy and better stability than linear SVM classifier in classification with lower dimension data. Hence, it proves the feasibility of rapid identification of five varieties of honeys with mid-infrared spectra combined with linear SVM or LSSVM.
