摘要:

近年来,学生学习成绩预测一直是一个研究热点,许多机构都致力于提高学生的学习成绩和教育质量。利用各种数据采掘技术可以实现对学生成绩的分析和预测。此外,这种技术允许教师确定可能影响学生最终分数的可能因素。为此,这项工作分析了两所不同大学的两个不同的本科生数据集。此外,这项工作的目的是预测学生的表现在两个阶段的课程交付(分别为20%和50%)。该分析允许适当地选择要使用的适当的机器学习算法以及优化算法的参数。此外,这项工作采用了一个系统的多分裂方法的基础上基尼指数和p值。这是通过优化一个合适的装袋集成学习器来完成的,该集成学习器是从六个潜在的基本机器学习算法的任何组合构建的。实验结果表明,所提出的bagging集成模型对两个数据集的目标群体都具有较高的精度。

英文摘要:

Predicting students' academic performance has been a research area of interest in recent years with many institutions focusing on improving the students' performance and the education quality. The analysis and prediction of students' performance can be achieved using various data mining techniques. Moreover, such techniques allow instructors to determine possible factors that may affect the students' final marks. To that end, this work analyzes two different undergraduate datasets at two different universities. Furthermore, this work aims to predict the students' performance at two stages of course delivery (20% and 50% respectively). This analysis allows for properly choosing the appropriate machine learning algorithms to use as well as optimize the algorithms' parameters. Furthermore, this work adopts a systematic multi-split approach based on Gini index and p-value. This is done by optimizing a suitable bagging ensemble learner that is built from any combination of six potential base machine learning algorithms. It is shown through experimental results that the posited bagging ensemble models achieve high accuracy for the target group for both datasets.
