Improvement of Apriori Algorithm and its Application in College Students PE Online Teaching System Platform

College students sports online teaching platform has good teaching effectiveness, so it has been popularized in the field of college physical education. However, due to time constraints, the effectiveness of this platform has not been fully played. Therefore, in order to solve this problem, this paper will focus on improving the Apriori algorithm to carry out research. The basic concept of Apriori algorithm is introduced, and then it is improved, and finally the system platform is reformed to promote the algorithm into the platform, and the reasonable application mode of algorithm in the system platform is introduced. Through the research, it is proved that the online teaching system platform can play a full role under the improved Apriori algorithm, and can effectively improve the quality of physical education.
