【摘要】 本文从实用的角度分析了C4.5算法的不足,提出了平衡决策树分类精度和分类规则简易性的观点。在此基础上,提出一个借助遗传算法进行属性组合寻优、进而实现决策树分类精度与规则简易性平衡的决策树优化算法,并为此设计了一个适应度函数。更多还原

【Abstract】 This paper analyzes the defects of C4.5 Algorithm from the practical angle and proposes the classification accuracy and the classification rules simplification. Based on these analyses, the paper presents a Decision Tree Optimization Algorithm by means of Genetic Algorithm, the Algorithm which is conducted first by attribute optimization then by realizing the classification accuracy and simplified rules balance of the Decision Tree.更多还原
