研究了不一致决策表的简化与属性约简问题,指出目前简化的决策表的局限:在简化的决策表上用现有的属性约简方法与在原决策表上基于正区域的属性约简方法,所得到的结果不一致.进一步对简化的决策表进行转换,得到新的决策表.基于正区域的属性约简,证明了在原决策表上约简与在新的决策表上约简结果相同.从而保证在实际应用中,对新的决策表可以用任意一种属性约简方法.
This paper studies the simplification and attribute reduction of the inconsistent decision table and points out the limitation of the current simplified decision table: using the existing attribute reduction method on the simplified decision table and the attribute reduction method based on the positive region on the original decision table, The results obtained are inconsistent.Furthermore, the simplified decision table is transformed to obtain a new decision table.Based on the attribute reduction in the positive region, it is proved that the reduction in the original decision table is the same as the reduction result in the new decision table In practice, we can use any attribute reduction method for the new decision table.
