The algorithm first uses the improved PSO optimized K-means algorithm (IPMeans) to cluster the intrusion data and increase the aggregation degree of the same data type. The promotion of education management informatization construction requires cooperation between higher vocational colleges and information technology companies, and cooperation with information technology companies. Brother colleges and universities cooperate and build together; at the same time, a high-quality information technology talent team is formed; the construction of information resources co-construction and sharing system is accelerated; the original unreasonable education management mechanism is reformed. Then the processed data is divided into 10-CV, and then use the cross-validation method to further improve the BP algorithm. The simulation results show that the BP algorithm based on cross-validation is better than the traditional BP algorithm.
