[HTML][HTML] A new modularity measure for fuzzy community detection problems based on overlap and grouping functions

D Gomez, JT Rodríguez, J Yanez, J Montero - International Journal of …, 2016 - Elsevier
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 measuring the …

n-Dimensional overlap functions

D Gómez, JT Rodriguez, J Montero, H Bustince… - Fuzzy Sets and …, 2016 - Elsevier
In this paper we introduce the definition of n-dimensional overlap functions and we justify the
axiomatization proposed in its definition. Basically, these functions allow to measure the …

Time series smoothing and OWA aggregation

RR Yager - IEEE Transactions on Fuzzy Systems, 2008 - ieeexplore.ieee.org
In this paper, an overview of the time series smoothing problem is provided and the role of
data aggregation is described using a weighted average of the past observations. Two …

A discussion on aggregation operators

D Gómez, J Montero - Kybernetika, 2004 - dml.cz
It has been lately made very clear that aggregation processes can not be based upon a
unique binary operator. Global aggregation operators have been therefore introduced as …

Using stress functions to obtain OWA operators

RR Yager - IEEE Transactions on Fuzzy Systems, 2007 - ieeexplore.ieee.org
The ordered weighted averaging operator attempts to provide a user-friendly class of mean
type aggregation operators by allowing a user to easily and naturally go from a mental …

Sobre las funciones y reglas de agregación

J Montero, D Gómez, V López, S Rodríguez… - 2010 - docta.ucm.es
En este adel lartículo se analiza la definición actualmente al uso de función de agregación,
haciendo hincapié en que, a pesar de considerar el problema de la variabilidad de la …

Strictly stable families of aggregation operators

K Rojas, D Gomez, J Montero, JT Rodríguez - Fuzzy sets and Systems, 2013 - Elsevier
In this paper we analyze the notion of family of aggregation operators (FAO), also refereed to
as extended aggregation functions (EAF), ie, a set of aggregation operators defined in the …

Computable aggregations

J Montero, R González-del-Campo, L Garmendia… - Information …, 2018 - Elsevier
In 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 …

Recursive and iterative OWA operators

L Troiano, RR Yager - International Journal of Uncertainty …, 2005 - World Scientific
An important issue when using the OWA aggregation operators is the determination of
weights. One approach is to link the weights to a desired attitudinal character for the …

Consistency and stability in aggregation operators: An application to missing data problems

D Gómez, K Rojas, J Montero… - International Journal …, 2014 - Taylor & Francis
In this work we analyze the key issue of the relationship that should hold between the
operators in a family {A n} of aggregation operators in order to understand they properly …
