粗集决策表与决策表简化的可信度比较

Comparison of the Reliability between Rough Set Decision Table and Reduction of Decision Table

摘要: 根据粗集决策表提供信息的完备性,借助可信度的定义,对粗集决策表和简化的决策表的决策规则的可信度进行比较,得出了简化后的决策表的决策规则的可信度高于简化前的决策表的决策规则的可信度,为粗集理论的应用提供了有用的分析工具。

Abstract: According to the perfection to supply information by rough set decision table, the reliabilities of decision table and reduction of decision table are compared on the definition of reliability. Then we draw the contusion that reduction of decision table is superior in reliability to decision table. It is an analytical tool for the implication of rough set theory.
