| 摘 要： | 连续不确定决策表可视为一种多值表元决策表。利用Fuzzy集理论可将多值表元决策表转换为带有隶属度的单一表元决策表;并在此基础上,给出了扩展信息表和决策表的定义,提出了对多值表元决策表中决策概念下近似及边界的计算方法,为利用规则推导算法产生知识提供了确定的输入。

| Abstract: | The DT with these entries named Continuous Uncertain Decision Table (CUDT) cannot be analyzed directly by CRST. Fortunately, by modeling those three types of entries in CUDT with Fuzzy sets theory, we found that CUDT can be transformed into a special DT called Extended Decision Table (EDT) in which each entry is associated with a membership degree. An extended CRST based on this idea is proposed to transform the CUDT into EDT, and the lower approximations and the boundaries of decision concepts in EDT are also calculated by our extended CRST as an input of the rule induction algorithms. |
