; Bustince Sola, Humberto 
(Universitat Politècnica de Catalunya, 1995)
Artículo / Artikulua 
This paper introduces the concept of intuitionistic fuzzy relation. We also study the choice of t-norms and t-conorms which must be done in order that the composition of intuitionistic fuzzy relations fulfills the largest ... -

Artículo / Artikulua
In this paper we study the effect of Atanassov's operator on the properties of properties reflexive, symmetric, antisymmetric, perfect antisymmetric and transitive intuitionistic fuzzy relations. We finish the paper analysing ... -
Is the phenotype designation by PSP-MDS criteria stable throughout the disease course and consistent with tau distribution?

Introduction: the MDS-PSP criteria have shown high sensitivity for the PSP diagnosis, but do not discriminate the phenotype diversity. Our purpose was to search for anatomopathological differences among PSP phenotypes ... -
IVTURS: A linguistic fuzzy rule-based classification system based on a new interval-valued fuzzy reasoning method with tuning and rule selection
Sanz Delgado, José Antonio ; Fernández, Alberto; Bustince Sola, Humberto ; Herrera, Francisco (IEEE, 2013)
Artículo / Artikulua
Interval-valued fuzzy sets have been shown to be a useful tool for dealing with the ignorance related to the definition of the linguistic labels. Specifically, they have been successfully applied to solve classification ... -

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 ... -
Linking mathematical morphology and L-fuzzy concepts

Artículo / Artikulua
In this paper we study the relation between L-fuzzy morphology and L-fuzzy concepts over complete lattices. In particular, we show how the erosion and dilation operators of the former can be understood in terms of the ... -
Medical diagnosis of cardiovascular diseases using an interval-valued fuzzy rule-based classification system
Sanz Delgado, José Antonio ; Galar Idoate, Mikel ; Jurío Munárriz, Aránzazu ; Brugos Larumbe, Antonio ; Pagola Barrio, Miguel ; Bustince Sola, Humberto (Elsevier, 2013)
Artículo / Artikulua
Objective: To develop a classifier that tackles the problem of determining the risk of a patient of suffering from a cardiovascular disease within the next ten years. The system has to provide both a diagnosis and an ... -
A method for inference in approximate reasoning based on normal intuitionistic fuzzy sets
Bustince Sola, Humberto ; Burillo López, Pedro ; Mohedano Salillas, Victoria (Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995)
Artículo / Artikulua
This paper introduces a method of approximate inference which operates with nornal intuitionistic fuzzy. We give a definition of degree of compatibility between intuitionistic fuzzy sets and we present a method for the ... -
Multivalued contexts associated with criteria
Alcalde, Cristina; Burusco Juandeaburre, Ana (Taylor & Francis, 2018)
Artículo / Artikulua
We are interested in the study of L-fuzzy contexts taking into account different criteria. These contexts arise when we want to analyze the relationship between objects and attributes from different points of view. ... -
New measures for comparing matrices and their application to image processing
Sesma Sara, Mikel ; Miguel Turullols, Laura de ; Pagola Barrio, Miguel ; Burusco Juandeaburre, Ana ; Mesiar, Radko; Bustince Sola, Humberto (Elsevier, 2018)
Artículo / Artikulua
In this work we present the class of matrix resemblance functions, i.e., functions that measure the difference between two matrices. We present two construction methods and study the properties that matrix resemblance ... -
New trends on the numerical representability of semiordered structures

Artículo / Artikulua
We introduce a survey, including the historical background, on di erent techniques that have recently been issued in the search for a characterization of the representability of semiordered structures, in the sense of ... -

Burillo López, Pedro; Fuentes González, Ramón ; González, L. (Universitat Politècnica de Catalunya, 1998)
Artículo / Artikulua
The concepts of bounded subset, complete subset and directed subset, which are well known in the context of partially ordered sets (X, ≤), are extended in order to become applicable, with coherence, in fuzzy relational ... -
