초록
Attribute reduction plays an important role in formal concept analysis. The existing work on attribute reduction of fuzzy formal context focuses mainly on one-sided fuzzy formal concepts. This paper is devoted to the study of attribute reduction for general L-fuzzy formal context. Some judgement theorems for a set of attributes to be consistent are presented. By using the discernibility function composed of discernibility attributes between related L-fuzzy formal concepts, an approach to compute attribute reductions is proposed. An illustrative example is presented which justify the method presented in this study.
Abstract
Attribute reduction plays an important role in formal concept analysis. The existing work on attribute reduction of fuzzy formal context focuses mainly on one-sided fuzzy formal concepts. This paper is devoted to the study of attribute reduction for general L-fuzzy formal context. Some judgement theorems for a set of attributes to be consistent are presented. By using the discernibility function composed of discernibility attributes between related L-fuzzy formal concepts, an approach to compute attribute reductions is proposed. An illustrative example is presented which justify the method presented in this study.
