Abstract:Shallow algorithms of mining and learning such as statistics, clustering, and association relationships are generally used in current research on the prediction and mining of college students' daily behaviors on campus, and there is a lack of in-depth and high-level analysis of the applications in time series, spatial location, and correlation of students' behaviors on campus. Based on the network structure of spatio-temporal graphs, this paper proposes a multifragment semantic spatiotemporal graph convolutional network (MFSTGCN) model that considers the time series of campus activities and the correlation between hierarchy and spatial semantic features. By constructing a data set of college students' campus behaviors and conducting experiments, the model in this paper achieves 90.4% behavior prediction accuracy, which is better than typical prediction models. Finally, we provide students with early warning of abnormal daily behaviors to monitor students' individual growth and excavate high-level information such as student's behaviors and habits to provide a meaningful reference for the construction of personalized education.
