Flores Vidal, Pablo Arcadio ; Villarino, Guillermo ; Gómez, Daniel ; Montero, Javier | Atlantis Press | 2019Traditionally, the last step of edge detection algorithms, which is called scaling-evaluation, produces the final output classifying each pixel as edge or nonedge. This last step is usually done based on local evaluation methods. The local evalu[...]texto impreso
In this paper we want to stress the relevance of paired fuzzy sets, as already proposed in previous works of the authors, as a family of fuzzy sets that offers a unifying view for different models based upon the opposition of two fuzzy sets, sim[...]texto impreso
Montero, Javier ; Bustince, H. ; Franco, C. ; Rodríguez, Juan Tinguaro ; Gómez, Daniel ; Pagola, Miguel ; Fernandez, Javier ; Barrenechea, Edurne | University of Copenhagen, Department of Food and Resource Economics | 2014In this strictly positional paper we propose a general approach to bipolar knowledge representation, where the meaning of concepts can be modelled by examining their decomposition into opposite and neutral categories. In particular, it is the se[...]texto impreso
Rodríguez, Juan Tinguaro ; Gómez, Daniel ; Yáñez, Javier ; Montero, Javier ; Franco, Camilo | Atlantis Press | 2015In this paper we present a new class of fuzzy sets, paired fuzzy sets, that tries to overcome any conflict between families of fuzzy sets that share a main characteristic: that they are generated from two basic opposite fuzzy sets. Hence, the fi[...]texto impreso
Opposition-based models are a current hot-topic in knowledge representation. The point of this paper is to suggest that opposition can be in fact introduced at two different levels, those of the predicates of interest being represented (as short[...]texto impreso
Montero, Javier ; Bustince, H. ; Franco, C. ; Rodríguez, Juan Tinguaro ; Gómez, Daniel ; Pagola, M. ; Fernández, J. ; Barrenechea, E. | Elservier | 2016In this position paper we propose a consistent and unifying view to all those basic knowledge representation models that are based on the existence of two somehow opposite fuzzy concepts. A number of these basic models can be found in fuzzy logi[...]texto impreso
The main contribution of this paper is to obtain a polynomial algorithm that allows us to classify step by step a set of items that are related by means of a fuzzy graph extending the algorithm published in [8] to any class of graph.texto impreso
Castro, Javier ; Gómez, Daniel ; Tejada Cazorla, Juan Antonio | Pergamon-Elsevier Science Ltd | 2009-05In this paper we develop a polynomial method based on sampling theory that can be used to estimate the Shapley value (or any semivalue) for cooperative games. Besides analyzing the complexity problem, we examine some desirable statistical proper[...]texto impreso
Castro, Javier ; Gómez, Daniel ; Tejada Cazorla, Juan Antonio | Pergamon-Elsevier Science Ltd | 2008In this paper we define the weighted serial cost sharing rule for the cost allocation problem.We apply this new rule to the problem of sharing delay costs in a PERT network. This rule belongs to the Core and is the Weighted Shapley Value for a p[...]texto impreso
This short note is written as a contribution to the memory of Prof. Da Ruan. We shall try to reflect how he was entitled to stay two months (April-May 2011) as “Distinguisher Visitor” at Complutense University, Madrid, based upon his past collab[...]texto impreso
An important topic in PERT networks is how to allocate the total expedition (or delay) for situations in which the project is not executed as planned. In order to do that we define a TU project game that satisfies some desirable properties from [...]texto impreso
In this paper, we define a new rule for the resolution of the slack allocation problem in a PERT network. This problem exists of allocating existing extra time in some paths among the activities belonging to those paths. The allocation rule that[...]texto impreso

En este trabajo se hace hincapie en el modelo de clasificacion subyacente dentro del marco de los Conjuntos Difusos Intuicionistas de Atanassov para justificar que la coincidencia formal con otros modelos solo se verifica en determinado contexto[...]texto impreso
Aggregation functions have been widely studied in literature. Nevertheless, few efforts have been dedicated to analyze those properties related with the family of operators in a global way. In this work, we analyze the stability in a family of a[...]texto impreso
Rojas, Karina ; Gómez, Daniel ; Montero, Javier ; Rodríguez, Juan Tinguaro | Elsevier Science BV | 2013-10-01In this paper we analyze the notion of family of aggregation operators (FAO), also refereed to as extended aggregation functions (EAF), i.e., a set of aggregation operators defined in the unit interval which aggregate several input values into a[...]texto impreso
In this paper we shall stress the key relevance of addressing a specific structure for the valuation space in Atanassov's IFS, which may help to establish certain di®erences with other related models. In particular, we point out that each one of[...]texto impreso
Gómez, Daniel ; Montero, Javier ; Yáñez, Javier ; González-Pachón, J. | Universitad de Lleida | 2003En la mayor?a de los problemas de decision se supone un conocimiento a priori acerca de los criterios que influyen en nuestras decisiones. Sin embargo, esta hipótesis parece no ser la mas adecuada en muchas situaciones. El concepto de dimension [...]
