| 摘 要： | 将粗糙集理论与模糊集理论相结合，提出了一种基于模糊粗糙集的知识获取方法．该方法利用模糊集理论对决策表中连续属性进行模糊化；通过定义模糊等价类得到模糊粗糙近似空间的上、下近似，从而获取决策规则．实例验证了此方法的有效性．

| Abstract: | A new method of knowledge acquisition based on fuzzy - rough set is proposed. The continuous attributes in the decision table are fuzzified with the fuzzy membership functions. Lower and upper approximation of fuzzy - rough set are obtained by defining fuzzy equivalence relation. According to them the decision rules are acquired. At last, an example is illustrated and proves that the approach is effective. |

| Keywords: | fuzzy-rough set decision table attribute reduction knowledge acquisition |
