Artículo / Artikulua
In this work, we introduce a new class of functions defned on the interval-valued setting. These functions extend classical OWA operators but allow for diferent weighting vectors to handle the lower bounds and the ... -

Artículo / Artikulua
This work tackles the comparison of radial data, and proposes comparison measures that are further applied to fingerprint analysis. First, we study the similarity of scalar and non-scalar radial data, elaborated on previous ... -

Join and meet operations for type-2 fuzzy sets with non-convex secondary memberships
Ruiz, Gonzalo; Hagras, Hani; Pomares, Héctor; Rojas, Ignacio; Bustince Sola, Humberto (IEEE, 2016)
Artículo / Artikulua
In this paper we will present two theorems for the join and meet operations for general type-2 fuzzy sets with arbitrary secondary memberships, which can be non-convex and/or non-normal type-1 fuzzy sets. These results ... -
