During the construction of a concept lattice, it has been recognized that computational complexity is a major obstacle in deriving all the concept … Webories and properties without changing the structure of formal fuzzy contexts from the perspectives of fuzzy logic. After that, Burusco et al. [20, 21] firstly illustrated L-fuzzy concept lattice, and made a comparison of the fuzziness in a given L-fuzzy formal context by utilizing the fuzzy implications of Luk asiewicz, Kleene [22], and G¨odel ... grade 12 maths past papers download

WebJan 1, 2015 · Discernibility matrices and Boolean functions are, respectively, employed to compute the attribute reducts and object reducts of the formal fuzzy contexts, by … 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 .
