New Negations on the Membership Functions of Type-2 Fuzzy Sets

Hernández-Varela, Pablo [Univ Mayor, Fac Estudios Interdisciplinarios, Nucleo Matemat Fis & Estadist]; Torres-Blanc, Carmen; Cubillo, Susana (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)

Type-2 fuzzy sets (T2FSs) were introduced by L. A. Zadeh in 1975 as an extension of type-1 fuzzy sets (T1FSs). In this extension, the degree to which an element belongs to a set is just a label of the linguistic ...
Self-contradiction for type-2 fuzzy sets whose membership degrees are normal and convex functions

Hernández-Varela, Pablo [Univ Mayor, Nucleo Matemat Fis & Estadist, Manuel Montt 318, Santiago, Chile]; Torres-Blanc, Carmen; Cubillo, Susana (ELSEVIER SCIENCE BV, 2018)

In order to detect contradictory information or to avoid conflicting outputs in processes of inference, the contradiction has been studied in the framework of fuzzy logic. It was found that a set A is N -self-contradictory ...
