摘要
近年来,大规模在线开放课程(Massive Open Online Courses, MOOCs)以其便捷性和开放性吸引了越来越多的学习者。然而,高辍学率问题一直难以解决,阻碍了mooc平台的进一步发展。需要一个准确的退学预测模型,能够有效地预测mooc的退学情况,并提前对学生进行干预。因此,本文提出了一种新的混合模型来预测学习者的辍学行为。该混合模型采用双通道卷积神经网络(CNN)从学生的学习记录中自动提取有用的特征,并利用注意机制获取重要信息,而不是人工提取特征。最后,应用时序卷积网络(TCN)捕捉不同时间尺度下隐藏特征之间的关系。通过在KDD CUP 2015数据集上的大量实验,我们可以了解到,与其他现有的辍学预测方法相比,本文提出的模型可以取得更好的结果。
A Hybrid Deep Learning Model for MOOCs Dropout Prediction
In recent years, Massive Open Online Courses (MOOCs) have attracted more and more learners due to its convenience and openness. However, the problem of high dropout rate has been difficult to solve, which hinders the further progress of MOOCs platforms. An accurate dropout prediction model that can effectively predict the dropout in MOOCs and intervene with students in advance is needed. Therefore, this paper proposes a novel hybrid model to predict learners' dropout behavior. Instead of manually extracting feature, this hybrid model designs a two-channel Convolutional Neural Network (CNN) to automatically extract useful feature from students' learning records, then employs Attention mechanism to obtain the important information. Finally, it applies Temporal Convolutional Network (TCN) to capture the relationships between hidden feature at different time scales. According to extensive experiments on the KDD CUP 2015 dataset, we can learn that the proposed model can achieve better results compared to other existing dropout prediction methods.
