摘要
决策树是一种重要的数据挖掘技术,本文分析了经典的ID3算法,并以我校金融工程专业程序设计课程为例,对ID3算法进行了仿真实验。实验结果表明:用检验样本对生成的决策树进行测试,测试结果符合率达91%以上。应用决策树规则对程序设计课程的总评成绩进行分析,提出了一些教学上有用的建议。
Decision tree is an important data mining technology. This paper analyzes the classic ID3 algorithm and conducts the simulation experiment of the ID3 algorithm based on the program design course in the financial engineering specialty of our university. Experimental results accord with the rate of more than 91% using the test sample to test the decision tree as generated. Besides, the decision tree rule is used to analyze the general score of the course with suggestions made.
