摘要
分类技术是根据数据集的特点找出类别的概念描述,这个概念描述代表了这类数据的整体信息,也就是该类的内涵描述。ID3算法是决策树归纳分类算法的一种,运用该算法建立学生专升本考试成绩分析决策树并从中提取出一些重要的规则。
Based on data set,sorting technique finds the concept description of sort, which represents the integrative information of this sort of data,ie the intension description of the sort of data. ID3 algorithm is a kind of decision-making tree inductive sorting algorithm. we use ID3 algorithm to construct analysis decision-making tree of academy-to-undergraduate students exam scores to extract some important rules.
