“…In their study, Yihui and Chiyu have stated that they have developed a feature extraction method, called FE_RF&T, and a variable/feature selection method, called OOPM. They found that the OOPM method, which has been used for feature selection, has advantageous compared to the Random Forest method, and that the FR_RF&T method has been more successful compared to the PCA method, according to the results of applying the proposed model on a sample data set including 16920 records with 22 variables, provided by the China Mobile Corp.
