Abstract The education management system is an important tool for universities to manage academic information and of staff students. article constructs a user behavior analysis model based on machine learning prediction LR-XGBoost analyze predict in the educational colleges universities. Specifically, after collection data university system, descriptive statistics cluster are performed. Then, relationship between dropout/leaving explored by model, performance tested comparing accuracy with other models. Cluster 3 users had significantly higher means 12 behaviors college than those clusters 2 1. Among behaviors, only closing web pages p-value greater 0.05 did not pass z-test. best 95.51% 94.53% behavioral anomalous prediction, respectively, F1 values 92.34% 95.33%, respectively. It has clear overall advantage predicting next 1-10 days.
