摘要
决策树是归纳学习和数据挖掘的重要方法,通常用来形成分类器和预测模型。分类器是数据挖掘的一种基本方法。本文对分类器的基本概念、C4.5算法、决策树的构建和剪枝进行了介绍,然后将C4.5算法应用于篮球比赛的技术统计分析中,通过对这些数据分析从而得到一些较实用的预测胜负规则。
Decision tree is an important method in induction as well as in data mining, which can be used to from classification and predictive model. Classifier is one of the basic methods of data mining. This paper presents the essential concepts of classifier, algorithm,thinks of constructing a decision tree and tree pruning. Then G4.5 algorithm is applied in a data analysis on statistics of the technique. Through analysis of these data and thus gaines some practical rules predicting winning or losing.
