This paper focuses on key issues related to aggregation tools within knowledge acquisition, and in particular for image processing. In particular, it is claimed the need of a number of simultaneous indices in order to evaluate the quality of a f[...]texto impreso
Rodríguez, Juan Tinguaro ; Franco, Camilo ; Vitoriano, Begoña ; Montero, Javier | Society for soft computing | 2011The concept of semantic antagonism refers to the human capability of characterizing those objects of an universe of discourse being dissimilar, significantly different from or opposite to a given concept, predicate or previous knowledge. This ca[...]texto impreso
Rodríguez, Juan Tinguaro ; Montero, Javier ; Vitoriano, Begoña ; Lopez, Victoria | Springer-Verlag Berlin Heidelberg | 2009Extraction of rules from databases for classification and decision tasks is an issue of growing importance as automated processes based on data are being required in these fields. An inductive methodology for data-based rules building and automa[...]texto impreso
Computing with words (CWW) explores the brain’s ability to handle and evaluate perceptions through language, i.e., by means of the linguistic representation of information and knowledge. On the other hand, standard preference structures examine [...]texto impreso
As recently proved in a previous work of Turunen, Tsoukias and Ozttirk, starting from an evidence pair (a, h) on the real unit square and associated with a propositional statement a, we can construct evidence matrices expressed in terms of four [...]texto impreso
Beliakov, G. ; Gomez, D. ; Jameson, Simon S ; Montero, Javier ; Rodríguez, Juan Tinguaro | Elsevier Science BV | 2017The problem of missing data is common in real-world applications of supervised machine learning such as classification and regression. Such data often gives rise to the need for functions defined for varying dimension. Here we propose optimizati[...]texto impreso
Villarino, Guillermo ; Gómez, Daniel ; Rodríguez, Juan Tinguaro ; Montero, Javier | Springer-Verlag | 2018Most supervised classification algorithms produce a soft score (either a probability, a fuzzy degree, a possibility, a cost, etc.) assessing the strength of the association between items and classes. After that, each item is assigned to the clas[...]texto impreso
Franco, Camilo ; Rodríguez, Juan Tinguaro ; Montero, Javier | World Scientific Publishing Company | 2014The polarity of concepts and the dialectic process by which its meaning emerges has been subject of interest since the ancient Greeks. Recently, the term Bipolarity has been used in social and mathematical sciences, referring to the measurement [...]texto impreso
Making decisions by learning preferences requires to consider semantical aspects dealing with the meaning and use of the preference concept. Examining recent developments on bipolarity, where concepts are measured/verified regarding a pair of op[...]texto impreso
En la gestión de desastres y emergencias, es crucial una valoración inicial correcta de las consecuencias de los fenómenos adversos para permitir una toma de decisiones adecuada. Sin embargo, no se requiere que esta valoración inicial sea necesa[...]texto impreso
A fully precise numerical evaluation of disasters’ effects is unrealistic in the time-pressured, highly uncertain decision context taking place just after a disaster strike. This is mainly due to some features of the available information in suc[...]texto impreso
Gauda, C. ; Gomez, D. ; Rodríguez, Juan Tinguaro ; Yáñez, Javier ; Montero, Javier | Atlantis Press | 2016In this paper we discuss some main image processing techniques in order to propose a classification based upon the output these methods provide. Because despite a particular image analysis technique can be supervised or unsupervised, and can all[...]texto impreso
Montero, Javier ; Gonzalez del Campo, Ramon ; Garmendia, Luis ; Gomez, D. ; Rodríguez, Juan Tinguaro | Elsevier Science INC | 2017-10-07In this paper, we postulate computation as a key element in assuring the consistency of a family of aggregation functions so that such a family of operators can be considered an aggregation rule. In particular, we suggest that the concept of an [...]texto impreso
Rodríguez, Juan Tinguaro ; López, V. ; Gomez, D. ; Vitoriano, Begoña ; Montero, Javier | IEEE | 2010The currently-in-use definition of aggregation function is analyzed in this paper, noting that the introduced variability in the dimension of information does not avoid some obvious dysfunctions. In particular, a potential abuse of the mathemati[...]texto impreso
In this preface we stress the relevance of the traditional collaboration between Engineering and any field of Mathematics in order to build intelligent decision-aid tools, as it is illustrated by the twelve papers contained in this Special Issue[...]texto impreso
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
Rodríguez, Juan Tinguaro ; Vitoriano, Begoña ; Montero, Javier ; Omaña, Antonio | World Scientific | 2008In this paper we present a decision support system for primary action of international organizations devoted to natural disaster relief In particular, we pretend to build up an expert system that taking into account past experiences will help de[...]texto impreso
Rojas, Karina ; Gómez, Daniel ; Montero, Javier ; Rodríguez, Juan Tinguaro ; Valdivia, Andrea ; Paiva, Francisco | Elsevier | 2014-04-16The interventions aimed at the early childhood are of a main interest in educational policy, since it is in this period when it is possible to produce a major impact in the subsequent human development. The quality of children's social environme[...]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[...]
