基于决策树的高校成人学籍查询方法研究

Research on Adult-student Status Querying Method Based on Decision Tree

高校成人学生来源广、差别大,学籍也十分复杂。学籍检索是学籍管理中的主要工作,通过构造决策树来发现学籍信息中蕴含的分类规则,利用这些规则可以在学籍信息中快速准确地进行查询。提出了一种基于决策树的学籍信息查询方法,分析了决策树建立的过程,讨论了过度拟合的处理方式,此方法可以提高学籍信息查询的速度和质量。

The sources of adult students in colleges are wide and the differences of them are big, so their student status is very complex. The main work of student status management is student status retrieval that is to find the classification rules contained in student status information through constructing the decision tree and to use these rules to do querying rapidly and accurately in student status information. This paper puts forward a student status information querying method based on the decision tree, analyzes the process of constructing the decision tree, and discusses the treatment of the over fitting,which can be used to improve the quality and speed of student status information query.
