Research on the Variety Discrimination of Apple Using a Hybrid Possibilistic Clustering
Near infrared reflectance (NIR) spectroscopy has been used to obtain NIR spectra of two varieties of apple samples.Thedimensionality of N IR spectra was reduced by principal component analysis (PCA),and discriminant information was extracted by linear discriminant analysis (LDA).Last,a hybrid possibilistic clustering algorithm (HPCA) was utilized as classifier to discriminate the apple samples of different varieties.HPCA integrates possibilistic clustering algorithm (PCA) and improved possibilistic c-means (IPCM) clustering algorithm,and produces not only the membership values but also typicality values by simple computation of the sample co-variance.Experimental results showed that HPCA,as an unsupervised learning algorithm,could quickly and easily discriminate the apple varieties.
