摘要: 在粗糙集中讨论概念格,定义粗糙形式背景、粗糙概念,给出它们的性质,在粗糙形式背景中借助蕴涵算子研究上、下近似运算,并且定义和讨论了粗糙Galois 连接。
关键词: 粗糙集, 粗糙概念, 概念格, 粗糙Galois连接
Abstract: we discuss concept lattice in rough sets,define rough formal context,rough concept,give their properties,study the lower(upper) approximate operators by means of implication in rough formal context,and investigate rough Galois connection.
Key words: rough set, rough concept, concept lattice, rough Galois connection
