Simulation System of College Physical Education Teaching Based on Decision Tree Algorithm and Data Mining

At present, computer technology has been popularized in physical education PE (Physical education) teaching in universities, and the complexity of PE teaching has been correspondingly increased in the reality of the huge increase in the quantity of students. This article introduces the decision tree algorithm and DM (Data mining) theory into the management of college PE, and introduces the basic concepts of college PE system theory. Based on the decision tree algorithm, the simulation system of college PE teaching is constructed. This article expounds the composition, structure and management of college PE simulation system, and gives the construction process of the system. The experimental results show that the PE simulation system based on decision tree algorithm and DM has certain reliability, and the stability of the system can still reach about 90% when there are many transaction sets. The results show that the teaching system in this article has certain superior performance, and it can be used as the basis to match the database information to generate the corresponding sports teaching decision scheme. This system increases the intelligence degree of PE teaching, reduces teachers’ time expenditure in teaching scheme design, and puts more time into teaching students in accordance with their aptitude.
