In order to exploit the effectiveness of FE methods to support Feature Selection (FS), this paper proposed a new FS approach for clustering based on Principal Component Analysis (PCA) called PS. It first uses PCA to transform the data from original feature space into a new feature space ...

In this paper, we establish the Students' evaluation of teaching (SET) discriminant analysis model and algorithm based on principal component clustering analysis. Additionally, we classify the SET by clustering the result of extracting the indexes through the principal component analysis (PCA), then ...
