Granular reducts of formal fuzzy contexts

WebBased on cognitive operators, granular reduct of dynamic formal context is studied. By using the cognitive operators, in the background of non-decision formal context, the new discernibility attribute sets in different states are given respectively when the objects and the attributes increased.
