摘要
讨论了基于模糊形式背景的模糊对象概念格的概念约简,构造出了模糊对象概念格的3种变精度概念格,即经典-模糊、模糊-经典、经典-经典变精度对象概念格,并讨论了它们的性质及相互关系。结果表明,变精度对象概念格的概念数量远远少于模糊对象概念格的概念数,而且每一种变精度概念格都保留了模糊对象概念格中相对重要的概念。
In this paper we discussed the conceptual reduction of fuzzy object-oriented concept lattices.Three kinds of variable threshold concept lattices,i.e.,crisp-crisp,crisp-fuzzy,fuzzy-crisp variable threshold object-oriented concept lattices,and the properties and the relations of them were discussed.The results shows that the number of concepts in variable threshold object-oriented concept lattices is less than that in fuzzy object-oriented concept lattices,and the important concept is preserved.
