Formal concept analysis, as an effective tool for knowledge discovery, has been successfully applied to various fields. This paper deals with approaches to generalized attribute reduction in consistent decision formal context. The concept of generalized attribute reduction in consistent decision formal context is first introduced. The judgement theorems and discernibility matrices are established,...
The Changkeng Au and Fuwang Ag deposits represent an economically significant and distinct member of the Au–Ag deposit association in China.
