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. WebIn this paper, a novel type of one-sided fuzzy three-way concept lattices is presented in a given formal fuzzy context with its complement, in which a ternary classification is available. In such case, we comprehensively explore the connections between the proposed models and classical fuzzy concept lattices among elements, sets, and orders.
