Bustince, H. ; Calvo, T. ; De Baets, B. ; Fodor, J. ; Mesiar, R. ; Montero, Javier ; Paternain, D. ; Pradera, A. | Elsevier Science INC | 2010In this paper we prove that, under suitable conditions, Atanassov’s Ka operators, which act on intervals, provide the same numerical results as OWA operators of dimension two. On one hand, this allows us to recover OWA operators from Ka operator[...]texto impreso
Bustince, H. ; De Baets, B. ; Fernande, J. ; Mesiar, R. ; Montero, Javier | Elsevier Science INC | 2012This paper brings a generalization of the migrativity property of aggregation functions, suggested in earlier work of some of the present authors by imposing the a-migrativity property of Durante and Sarkoci for all values of a instead of a sing[...]texto impreso
We introduce a slight modification of the definition of migrativity for aggregation functions that allows useful characterization of this property. Among other things, in this context we prove that there are no t-conorms, uninorms or nullnorms t[...]texto impreso
In this paper we address a key issue in scenario classification, where classifying concepts show a natural overlapping. In fact, overlapping needs to be evaluated whenever classes are not crisp, in order to be able to check if a certain classifi[...]texto impreso
In this work we study some properties of overlap functions from an analytical point of view. We study the relation between overlap functions and continuous t-norms. We focus on homogeneous overlap functions and we get a characterization of them.[...]texto impreso
Bustince, H. ; Fernández, J. ; Mesiar, R. ; Montero, Javier ; Orduna, R | European Society of Fuzzy Logic and Technology | 2009-07-20In this work we study overlap degrees expressed in terms of overlap functions. We present the basic properties that from our point of view must satisfy these overlap functions. We study a construction method, we analyze which t-norms are also ov[...]texto impreso
Bustince, Humberto ; Fernandez, Javier ; De Baets, B. ; Montero, Javier ; Mesiar, R. | Universidad de Huelva, Servicio de Publicaciones | 2010En este trabajo presentamos una generalizacion de los conceptos de funcion migrativa y funcion migrativa. En particular, nos centramos en la relacion de estas funciones migrativas generalizadas con algunas propiedades habitualmente requeridas a [...]
