WebLet 𝔽 = (U, A, ˜I) be a fuzzy formal context. For any X ⊆ U, X is said to be an object granular consistent set of 𝔽 if [ a ] RX = [ a ] R for all a ∈ A. Furthermore, if X is an object granular consistent set and [ a ] RX- {x} ≠ [ a ] R for all x ∈ X, then X is referred to as an object granular reduction of 𝔽 . 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.
