摘要
对简化的决策表进行转换,得到改进的简化决策表。基于正区域的属性约简,证明了在原决策表上约简与在改进的简化决策表上约简,结果相同。由于改进的简化决策表是一致的,从而保证在实际应用中,对改进的简化决策表可以用现有的任意一种完备的属性约简算法。
An improved decision table is acquired by converting simple decision table into consistent decision table. Based on positive region, proves that the attributes reduction in the original decision table is the same as in the improved simple decision table. Because of the improved simple decision table is consistent, every complete algorithm of attributes reduction can be used for the improved decision table in practice.
