A fuzzy methodology for approaching fuzzy sets of the real line by fuzzy numbers

Roldán López de Hierro, Antonio Francisco; Tíscar, Miguel Ángel; Roldán, Concepción; Bustince Sola, Humberto

(Elsevier, 2021) Artículo / Artikulua

In this paper we introduce a novel methodology to face the problem of finding, for every fuzzy set of the real line, a fuzzy number which can be considered as an approximation of the first one in some reasonable sense. ...

On the notion of fuzzy dispersion measure and its application to triangular fuzzy numbers

Roldán López de Hierro, Antonio Francisco; Bustince Sola, Humberto

; Rueda, María del Mar; Roldán, Concepción; Miguel Turullols, Laura de

; Guerra, Carlos

(Elsevier, 2023) Artículo / Artikulua

In this paper, based on the analysis of the most widely used dispersion measure in the real context (namely, the variance), we introduce the notion of fuzzy dispersion measure associated to a finite set of data given by ...

Type-(2, k) overlap indices

Roldán López de Hierro, Antonio Francisco; Roldán, Concepción; Tíscar, Miguel Ángel; Takáč, Zdenko; Santiago, Regivan; Bustince Sola, Humberto

(IEEE, 2022) Artículo / Artikulua

Automatic image detection is one of the most im- portant areas in computing due to its potential application in numerous real-world scenarios. One important tool to deal with that is called overlap indices. They were ...
