A notion of intuitionistic fuzzy subfield is presented, which based on intuitionistic fuzzy sets. At the same time, we consider its some main properties and study up on its equivalent characterizations. The emphasis here is on some equivalent characterizations of intuitionistic fuzzy subfield. It is proved that our method presented in this paper is useful.
To remove the redundant features extracted by using 2DPCA methods, a face recognition method is presented based on 2DPCA and fuzzy-rough technique in this paper. The proposed method selects the important features for classification by using attribute reduction in fuzzy rough sets theory. The experimental results show the proposed method outperforms the face recognition methods based on 2DPCA.
A notion of intuitionistic fuzzy sublattice group is presented in this paper, which based on intuitionistic fuzzy sets. At the same time, we consider its some main properties and study up on its equivalent characterizations. The emphasis here is on some equivalent characterizations of intuitionistic fuzzy sublattice group. It is proved that our method presented in this paper is useful.
A notion of intuitionistic fuzzy subgroups and ordinary intuitionistic fuzzy subgroups is presented in this paper, which based on intuitionistic fuzzy sets. At the same time, whose some considered properties are presented. The emphasis here is on some equivalent characterizations of intuitionistic fuzzy subgroups. The equivalent characterizations based on level cut sets. It is proved that the method...
