论促使决策树重构的因素

The Factors of Reconstruction of Decision Trees

本文首先阐述了数据挖掘中决策树的基本思想,然后简单介绍了决策树经典算法(ID3算法),重点基于ID3算法论述了对于决策树的影响4个要素,并使用真实的数据详细地分析了4个要素,实验表明,只要4个要素中的任何一个改变,决策树必须要重新被构建。

The paper firstly discribes the basic thoughts of decision trees in data mining,then simply introduces the classical algorithms of decision trees,ID3 algorithm.Based on ID3 algorithm and by using real data,the emphasis is on the four elements that influence the decision trees.The experiment shows that as long as any one of the four elements changes,the decision tree must to be reconstructed.
