Student performance prediction model based on discriminative feature selection

Abstract

It is a hot issue to be widely studied to determine the factors affecting students' performance from the perspective of data mining. In order to find the key factors that significantly affect students' performance from complex data, this paper proposes an integrated Optimized Ensemble Feature Selection Algorithm by Density Peaks (DPEFS). This algorithm is applied to the education data collected by two high schools in China, and the selected discriminative features are used to construct a student performance prediction model based on support vector machine (SVM). The results of the 10-fold cross-validation experiment show that, compared with various feature selection algorithms such as mRMR, Relief, SVM-RFE and AVC, the SVM student performance prediction model based on the feature selection algorithm proposed in this paper has better prediction performance. In addition, some factors and rules affecting student performance can be extracted from the discriminative features selected by the feature selection algorithm in this paper, which provides a methodological and technical reference for teachers, education management staffs and schools to predict and analyze the students' performances.
