The availability of educational data obtained by technology-assisted learning platforms can potentially be used to mine student behavior in order to address their problems and enhance the learning process. Educational data mining provides insights for professionals to make appropriate decisions. Learning platforms complement traditional learning environments and provide an opportunity to analyze students' performance, thus mitigating the probability of student failures. Predicting students' academic performance has become an important research area to take timely corrective actions, thereby increasing the efficacy of education systems. This study proposes an improved conditional generative adversarial network (CGAN) in combination with a deep-layer-based support vector machine (SVM) to predict students' performance through school and home tutoring. Students' educational datasets are predominantly small in size; to handle this problem, synthetic data samples are generated by an improved CGAN. To prove its effectiveness, results are compared with and without applying CGAN. Results indicate that school and home tutoring combined have a positive impact on students' performance when the model is trained after applying CGAN. For an extensive evaluation of deep SVM, multiple kernel-based approaches are investigated, including radial, linear, sigmoid, and polynomial functions, and their performance is analyzed. The proposed improved CGAN coupled with deep SVM outperforms in terms of sensitivity, specificity, and area under the curve when compared with solutions from the existing literature.
通过技术辅助学习平台获得的教育数据可以被挖掘出来,以解决学生的问题并提高学习过程。教育数据挖掘为专业人员提供了做出适当决策的洞察力。学习平台补充了传统的学习环境,提供了分析学生表现的机会,从而降低了学生失败的概率。预测学生的学业成绩已经成为一个重要的研究领域,以便及时采取纠正措施,从而提高教育系统的效果。本研究提出了一种改进的条件生成对抗网络(CGAN)与基于深层的支持向量机(SVM)相结合,通过学校和家庭辅导来预测学生的成绩。学生的教育数据集主要是小的;为了解决这个问题,通过改进的 CGAN 生成合成数据样本。为了证明其有效性,将结果与不应用 CGAN 进行了比较。结果表明,当应用 CGAN 后进行训练时,学校和家庭辅导相结合对学生的表现有积极的影响。为了对深度 SVM 进行广泛的评估,研究了包括径向、线性、 sigmoid 和多项式函数在内的多种核基方法,并分析了它们的性能。与现有文献中的解决方案相比,所提出的改进的 CGAN 与深度 SVM 相结合在灵敏度、特异性和曲线下面积方面表现更好。
