    Student Behavioral Temporal Modeling Sensitive to Abnormal Behavior for Mental Health Prediction Method

    • 摘要: 为了对学生异常行为的早期感知及校园行为时序建模, 提出一种异常行为敏感的学生行为时序建模及心理健康预测(student behavioral temporal modeling sensitive to abnormal behavior for mental health prediction, SBTM-SABMHP)方法, 利用移动设备收集的加速器、声音传感器及移动热点(wireless fidelity, WI-FI)等多种行为感知数据, 构建异质信息网络, 对学生当前行为模式进行建模。同时, 为实现对学生历史行为时序数据的建模, 建立了基于注意力机制的异常行为敏感的门控模块, 有效融合学生长短期行为, 并对学生行为时序建模, 实现心理健康预测。在公共数据集StudentLife上对所提出的模型进行了对比分析实验。实验结果表明, 与多种学生心理健康预测基线方法相比, 该方法在4个评价指标上都取得了最佳性能, 证明了该模型在学生心理健康预测任务上的有效性。

       

      Abstract: To achieve the early perception and modeling of abnormal student behavior, a method of student behavioral temporal modeling sensitive to abnormal behavior for mental health prediction (SBTM-SABMHP) was proposed. A heterogeneous information network was constructed to model students' current behavioral patterns using multiple behavioral sensing data collected by mobile devices such as accelerometers, sound sensors, and wireless fidelity (WI-FI). Furthermore, an attention mechanism-based abnormal behavior-sensitive gating module was built for historical behavioral temporal data to effectively integrate long- and short-term behaviors of students. In this way, students' temporal behaviors were modeled, and mental health status prediction was achieved. The comparative analysis experiments of the proposed model were conducted on the public dataset StudentLife. Results show that this method achieves the best performance on all evaluation metrics compared to all other baseline methods for student mental status prediction, demonstrating the effectiveness for student mental health prediction tasks.
