AI总结:

本文评估经典机器学习模型对学生学业表现的预测能力,发现MLPC表现最佳,并结合特征选择与可解释机器学习验证模型有效性。

摘要:

本研究调查了在学校环境中使用机器学习方法预测学生学业表现。包含行为、学业和人口统计细节的学生数据被用于多种标准经典机器学习模型的实现,其中包括多层感知机分类器(MLPC)。在所有实现中,MLPC在测试集上取得了86.46%的最高准确率。在10折交叉验证下,MLPC在测试集上取得79.58%的平均准确率,而在训练集上则为99.65%。MLP相较于其他机器学习模型更优的表现,有力表明神经网络具有作为数据高效模型的应用潜力。特征选择方法在提升性能方面发挥了关键作用;研究还采用多种评估方法,以便与现有文献进行比较。可解释机器学习方法被用于揭开黑盒模型的神秘面纱,并验证特征选择方法。

英文摘要:

This research investigates the use of machine learning methods to forecast students' academic performance in a school setting. Students' data with behavioral, academic, and demographic details were used in implementations with standard classical machine learning models including multi-layer perceptron classifier (MLPC). MLPC obtained 86.46% maximum accuracy for test set across all implementations. Under 10-fold cross validation, MLPC obtained 79.58% average accuracy for test set while for train set, it was 99.65%. MLP's better performance over other machine learning models strongly suggest the potential use of neural networks as data-efficient models. Feature selection approach played a crucial role in improving the performance and multiple evaluation approaches were used in order to compare with existing literature. Explainable machine learning methods were utilized to demystify the black box models and to validate the feature selection approach.
