Title: Application of PCA and KPCA in Comprehensive Evaluation
Abstract: The score of comprehensive evaluation was computed using principal component analysis(PCA) and kernel principal component analysis(KPCA) separately.The results show that the PCA is a simple and practical approach,whereas there are two defects of using KPCA: 1) kernel function and kernel parameter seriously affects the calculation of composite scores.2) It is difficult to explain the kernel principal component.The better result will be achieved when computes the comprehensive score by using KPCA,if takes the PCA analysis as the reference.
