N-dimensional admissibly ordered interval-valued overlap functions and its influence in interval-valued fuzzy rule-based classification systems
(IEEE, 2021)
info:eu-repo/semantics/article,
Overlap functions are a type of aggregation functions that are not required to be associative, generally used to indicate the overlapping degree between two values. They have been successfully used as a conjunction operator ...
Similarity between interval-valued fuzzy sets taking into account the width of the intervals and admissible orders
(Elsevier, 2020)
info:eu-repo/semantics/article,
In this work we study a new class of similarity measures between interval-valued fuzzy sets. The novelty of our approach lays, firstly, on the fact that we develop all the notions with respect to total orders of intervals; ...
A proposal for tuning the α parameter in CαC-integrals for application in fuzzy rule-based classification systems
(Springer, 2020)
info:eu-repo/semantics/article,
In this paper, we consider the concept of extended Choquet integral generalized by a copula, called CC-integral. In particular, we adopt a CC-integral that uses a copula defined by a parameter α, which behavior was tested ...
Interval-valued Atanassov intuitionistic OWA aggregations using admissible linear orders and their application to decision making
(IEEE, 2016)
Artículo / Artikulua,
Based on the definition of admissible order for
interval-valued Atanassov intuitionistic fuzzy sets, we study
OWA operators in these sets distinguishing between the weights
associated to the membership and those associated ...
Unbalanced interval-valued OWA operators
(Springer Berlin Heidelberg, 2016)
Artículo / Artikulua,
In this work, we introduce a new class of functions defned on the
interval-valued setting. These functions extend classical OWA operators but
allow for diferent weighting vectors to handle the lower bounds and the ...
General grouping functions
(Springer, 2020)
info:eu-repo/semantics/conferenceObject,
Some aggregation functions that are not necessarily associative, namely overlap and grouping functions, have called the attention of many researchers in the recent past. This is probably due to the fact that they are a ...
Linking mathematical morphology and L-fuzzy concepts
(World Scientific, 2017)
Artículo / Artikulua,
In this paper we study the relation between L-fuzzy morphology and L-fuzzy concepts
over complete lattices. In particular, we show how the erosion and dilation operators of
the former can be understood in terms of the ...
The Krypteia ensemble: designing classifier ensembles using an ancient Spartan military tradition
(Elsevier, 2023)
Artículo / Artikulua,
In this work we propose a new algorithm to train and optimize an ensemble of classifiers. We call this algorithm the Krypteia ensemble, based on an ancient Spartan tradition designed to convert their most promising individuals ...
An algorithm for group decision making using n -dimensional fuzzy sets, admissible orders and OWA operators
(Elsevier, 2017)
Artículo / Artikulua,
In this paper we propose an algorithm to solve group decision making problems using n -dimensional fuzzy sets, namely, sets in which the membership degree of each element to the set is given by an in- creasing tuple of n ...
FUZZ-EQ: a data equalizer for boosting the discrimination power of fuzzy classifiers
(Elsevier, 2020)
info:eu-repo/semantics/article,
The definition of linguistic terms is a critical part of the construction of any fuzzy classifier. Fuzzy partitioning methods (FPMs) range from simple uniform partitioning to sophisticated optimization algorithms. In this ...
