Consistencia y estabilidad en operadores de agregación: Una aplicación al problema de datos perdidos
Gómez, Daniel ; Rojas, Karina ; Montero, Javier ; Rodríguez, Juan Tinguaro ; Beliakov, G. | Universidad de Zaragoza | 2014En este trabajo se analiza una cuestión clave respecto de la relación que debe existir entre operadores de una misma familia de operadores de agregación (FAO) {An}, a fin de comprender que ellos deben definir adecuadamente un todo consistente. S[...]texto impreso
Gómez, Daniel ; Rojas Patuelli, Karina ; Montero, Javier ; Rodríguez, Juan Tinguaro | Springer-Verlag Berlin Heidelberg | 2013In this work we analyze the key issue of the relationship that should hold between the operators in a family {An} of aggregation operators in order to understand they properly define a consistent whole. Here we extend some of the ideas about sta[...]texto impreso
In this work, we continue with a previous work in which we analyzed and defined notions of consistency, stability and continuity of a family of aggregation operators (FAO) when the data is unstructured. Here we use these concepts to tackle with [...]texto impreso
This article is devoted to the replication of the nternal methodologies of credit rating agencies for rating lassification using fuzzy algorithms. To achieve this goal, the usage of different types of fuzzy algorithms (evolutionary and non-evolu[...]texto impreso
Rodríguez, Juan Tinguaro ; Vitoriano, Begoña ; Montero, Javier | Academic Publishing House EXIT | 2008In this paper we stress the role that decision making, and therefore an underlying binary (bipolar) approach, plays in Atanassov's intuitionistic view of fuzzy sets. Moreover, we point out that such a bipolar view can be found in classical multi[...]texto impreso

This paper aims to provide a comparative analysis of fuzzy rule-based systems and some standard statistical and other machine learning techniques in the context of the development of a decision support system (DSS) for the assessment of the seve[...]texto impreso
Frequently, the set of classes of a supervised classification problem presents an structure related to the specific features of each application context. However, standard classification models does not use to consider such an structure in their[...]texto impreso
Lopez, Victoria ; Montero, Javier ; Rodríguez, Juan Tinguaro | World Scientific Publishing Company | 2010This paper recalls some criticisms to the currently-in-use definition of aggregation function, concerning, firstly, the lack of conditions that guarantee the conceptual harmonization of the sequence of operators and, second, the possibility of t[...]texto impreso
Bustince, H. ; Barrenechea, Edurne ; Burusco, Ana ; Fernandez, Javier ; Rodríguez, Juan Tinguaro ; Montero, Javier ; Pagola, Miguel ; Gomez, D. | Springer International Publishing | 2015In 1979, Enric Trillas started to interest in in fuzzy connectives. His first paper on this topic was ”Funciones de negacin en la teora de subconjuntos difusos” ([9]) (Negation functions in the theory of fuzzy subsets), which appeared in Spanish[...]texto impreso
Fuzziness and bipolarity allow representing human knowledge, taking into account the gradual and the dialectic properties of language, focusing on the meaning of concepts. Under this cognitive and linguistic approach, we explore preference relat[...]texto impreso
One of the main challenges of fuzzy community detection problems is to be able to measure the quality of a fuzzy partition. In this paper, we present an alternative way of measure the quality of a fuzzy community detection output based on n-dime[...]texto impreso
A correct initial assessment of disaster consequences is crucial for an adequate decision-making in disaster and emergency management. However, such an initial assessment needs to be correct, but not necessarily fully precise, and thus it can be[...]texto impreso
Guada, Carely ; Gómez, Daniel ; Rodríguez, Juan Tinguaro ; Yáñez, Javier ; Montero, Javier | Atlantis Press | 2015In this paper, we present a way to define the concept of fuzzy image segmentation, which has not been clearly defined in the literature.
