摘要
对于决策表的属性约简,通过分析最小相关性最大依赖度属性约简算法,得到了一种更加完善的最小相关性最大依赖度属性约简算法,并通过实例验证其可行性.
For attribute reduction in decision table, after analyzing the algorithm which calculates the reduction with the principle of minimal correlation and maximal dependency,an improved algorithm with the principle of minimal correlation and maximal dependency is found out. An example is used to check the feasibility of this algorithm.
