基于决策树的税务数据分析

Analysis of Tariff Data based on Decision Tree

本文介绍了决策树的概念及生成过程,研究了利用基尼系数来选取值的算法,并将它集成到税务数据分析系统中,描述了构造税务数据分析系统所采用的方案,并提出了今后决策树研究要解决的一些问题。

The paper introduces the principle of the decision tree and process of building it, then studys the arithmetic basedon the Gini-index, and integrates them in decision tree analysis system. We describe the schema of the contructing tariff data analysis system. After analyzing the tariff data, we propose some solutions.
