The construction of fuzzy concept lattice based on weighted complete graph

Research on rule extraction method based on concept lattice of intuitionistic fuzzy language

“…Extracting implicit and potential rules from information systems is the key step to achieve knowledge acquisition. In the traditional expert system or fuzzy reasoning system, rules are often given by experts according to their experience, which may lead to some problems [12] owing to the fact that the rules acquired based on classical rough set theory are often clear rules with steep truncation, and compared with fuzzy rules, their generalisation ability and practicability are weak [13]. Intuitionistic fuzzy sets (IFS) constitute an important extension of fuzzy sets; their mathematical description is more in line with the nature of fuzzy objects in the objective world, and IFS have thus become a new research hotspot in recent years [14].…”

The Decomposition for the α-level Fuzzy Soft Sets

“…And others have done the study of fuzzy soft lattice from perspective of both fuzzy set and lattice, such as, in [9], the author defined the concept for soft lattices, and in [10], the notion of fuzzy soft lattice was defined and extended the notion of a fuzzy lattice to include the algebraic structures of soft set. To attain more information you can see [11]- [15]. In [16], authors defined the α-level fuzzy soft sets (lattices).…”
