Over the last decades, many fuzzy classification algorithms have been proposed for image classification,and in particular to classify those images obtained by remote sensing. But relatively little effort has been done to evaluate goodness or eff[...]texto impreso
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
Diversos estudios se han centrado en analizar amplia y profundamente distintas propiedades de los operadores de agregación. Sin embargo, no ha ocurrido lo mismo en el estudio de propiedades relativas a las Familias de Operadores de Agregación. ¿[...]texto impreso
In a previous paper, the authors proposed an alternative approach to classical dimension theory, based upon a generaltexto impreso
n this work we present an improvement on an iterative binary coloring procedure for image segmentation taken from the literature. We introduce some modifications in the way of dealing with the so-called inconsistent pixels, and we show the resul[...]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

En este trabajo se propone un algoritmo de clasificación no supervisada y jerárquica sobre un conjunto de objetos modelizados mediante un grafo. La salida de este algoritmo muestra la evolución de cómo los grupos se van rompiendo en la red de ma[...]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

One of the main problems in practice is the difficulty in dealing with membership functions. Many decision makers ask for a graphical representation to help them to visualize results. In this paper, we point out that some useful tools for fuzzy [...]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
Gomez, D. ; Montero, Javier ; Yáñez, Javier ; González-Pachón, J. ; Cutello, V. | Taylor & Francis Ltd | 2004In this paper we address the problem of inconsistency in preference relations, pointing out the relevance of a meaningful representation in order to help decision maker to capture such inconsistencies. Dimension theory framework, despite its com[...]
