信息熵与决策之间关系的讨论

摘要

Discusses and draws a conclusion:the information representationin information entropy and rough set can be converted into each other. But there doesn't exist necessary connection between information entropy and whether the attribute can be ignored or not in the inconsistent decision table.%讨论了在一致决策表中，信息熵与粗糙集理论中的信息表示可相互转化，但在不一致决策表中，信息熵与属性是否可省并没有必然的联系。
