An important topic in using maps derived from a statistical classifier is the accuracy assessment of the classification. Analysts usually need to compare various techniques, algorithms, or different approaches. As pointed out by Stehman and Czap[...]texto impreso
The SPERT problem was defined, in a game theory framework, as the fair allocation of the slack or float among the activities in a PERT network previous to the execution of the project. Previous approaches tackle with this problem imposing that t[...]texto impreso

In this paper we show that Atanassov's Intuitionistic Fuzzy sets can be viewed as a classification model, that can be generalized in order to take into account more classes than the three classes considered by Atanassov's (membership, non-member[...]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
Gómez, Daniel ; González-Arangüena, Enrique ; Conrado, Manuel ; Owen, Guillermo ; Pozo Juan, Mónica del ; Tejada Cazorla, Juan Antonio | Elsevier | 2003-08A new family of centrality measures, based on game theoretical concepts, is proposed for social networks. To reflect the interests that motivate the interactions among individuals in a network, a cooperative game in characteristic function form [...]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
A large number of accuracy measures for crisp supervised classification have been developed in supervised image classification literature. Overall accuracy, Kappa index, Kappa location, Kappa histo and user accuracy are some well-known examples.[...]texto impreso
A large number of accuracy measures for image classification are actually available in the literature for cris classification. Overall accuracy, producer accuracy, user accuracy, kappa index and tau value are some examples. But in contrast to th[...]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
In this paper we present a divisive hierarchical method for the analysis and segmentation of visual images. The proposed method is based on the use of the k-means method embedded in a recursive algorithm to obtain a clustering at each node of th[...]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
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. In this work the term Fuzzy image segmentation is characterized by means of a fuzzy set over the set of edge[...]
