近年来,许多研究探索了使用机器学习算法来支持社会和临床心理学的应用。特别是,通过嵌入式传感器和有效的现场调查问卷收集数据的基于智能手机的技术越来越普遍。然后构建模型来探索这些数据类型之间的模式。本文基于摄影式情感测量仪的数据,研究了机器学习在预测不良情绪心理状态中的应用。我们提出了一种技术,每天聚集,这是为了检测重大的负面事件。使用各种功能作为输入,包括基于GPS的指标和评估社交互动,睡眠和电话使用的功能。实验证据,这表明,机器学习算法可以成功地用于这样的预测任务。
In recent years, numerous studies have explored the use of machine learning algorithms for supporting applications in social and clinical psychology. In particular, there is an increasing prevalence of smartphone-based techniques for collecting data through embedded sensors and efficient in-situ questionnaires. Models are then built to explore the patterns between these data types. In this paper, we study the application of machine learning for the task of predicting mental states of adverse valence, based on the Photographic Affect Meter data. We present a technique for daily aggregation, which is designed to detect significant negative events. A variety of features is used as input, including GPS-based metrics and features assessing social interactions, sleep and phone usage. Experimental evidence is presented, which suggests that machine learning algorithms could successfully be employed for such a prediction task.
