摘要
通过介绍数据挖掘的概念和决策树分类方法,论述了ID3算法的基本思想和实现方法,并用该算法对学生计算机成绩进行分析,构造计算机成绩决策树并从中提取出一些重要规则,为教师教和学生学提供参考依据.
In the article, the definition of data mining and the division of decision tree are firstly introduced, then basic theories concerning ID3 method and its application are discussed, and finally a case study is made to analyze students＇ computer examination grades by using ID3 method. Based on them, computer examination grades decision tree is formed from which some important principles are deduced, which, are considered to be reference for both teachers and students in their teaching and study.
