On Extensions of Quasi-Overlap and Quasi-Grouping Functions Defined on Bounded Lattices
Ana Shirley Monteiro, Regivan Santiago, Benjamín Bedregal +2
In this paper, we propose a method of extending quasi-overlap and grouping functions defined on a sublattice of a bounded lattice to this lattice considering a more gen…
Abstract homogeneity of interval-valued functions
Ana Shirley Monteiro, Regivan Santiago, Radko Mesiar +4
In this paper we develop the idea of abstract homogeneity in the context of interval-valued (IV) functions endowed with admissible orders and investigate some of its properties.
On Monotonicities of Interval Valued Functions
Ana Shirley Monteiro, Regivan Santiago, Martin Papco +2
In this paper, we develop the notions of weak/directional monotonicity (developed by Sesma-Sara et al. in terms of the \emph{Kulisch-Miranker order}) and the notion of -monoto…
(,,)-Implications
Fernando Neres, Benjamín Bedregal, Regivan H. N. Santiago
In this paper we introduce a new class of fuzzy implications called (,,)-implications inspired in the logical equivalence $p\rightarrow q \equiv \neg(p\wedge\neg q)\vee\ne…
Fuzzy implication functions constructed from general overlap functions and fuzzy negations
Jocivania Pinheiro, Benjamin Bedregal, Regivan H. N. Santiago +3
Fuzzy implication functions have been widely investigated, both in theoretical and practical fields. The aim of this work is to continue previous works related to fuzzy implication…
On Typical Hesitant Fuzzy Languages and Automata
Valdigleis S. Costa, Benjamín C. Bedregal, Regivan H. N. Santiago
The idea of nondeterministic typical hesitant fuzzy automata is a generalization of the fuzzy automata presented by Costa and Bedregal. This paper, presents the sufficient and nece…
Residuated implications derived from quasi-overlap functions on lattices
Rui Paiva, Benjamín Bedregal, Regivan Santiago
In this paper, we introduce the concept of residuated implications derived from quasi-overlap functions on lattices and prove some related properties. In addition, we formalized th…
Lattice-valued Overlap and Quasi-Overlap Functions
Rui Paiva, Eduardo Palmeira, Regivan Santiago +1
Overlap functions were introduced as class of bivariate aggregation functions on [0, 1] to be applied in image processing. This paper has as main objective to present appropriates…
Bounded Generalized Mixture Functions
Antonio Diego S. Farias, Valdigleis S. Costa, Luiz Ranyer de Araújo Lopes +2
In literature, it is common to find problems which require a way to encode a finite set of information into a single data; usually means are used for that. An important generalizat…
Dynamic Ordered Weighted Averaging Functions for Complete Lattices
Antonio Diego S. Farias, Regivan H. N. Santiago, Benjamín Bedregal
In this paper we introduce a class of operators on complete lattices called Dynamic Ordered Weighted Averaging (DYOWA) functions. These functions provide a generalized form of an i…
Combining Multiple Algorithms in Classifier Ensembles using Generalized Mixture Functions
Valdigleis S. Costaa, Antonio Diego S. Farias, Benjamín Bedregal +2
Classifier ensembles are pattern recognition structures composed of a set of classification algorithms (members), organized in a parallel way, and a combination method with the aim…
Semi-BCI Algebras
Regivan H. N. Santiago, Benjamin Bedregal, João Marcos +2
The notion of semi-BCI algebras is introduced and some of its properties are investigated. This algebra is another generalization for BCI-algebras. It arises from the "intervalizat…
A Method for Image Reduction Based on a Generalization of Ordered Weighted Averaging Functions
A. Diego S. Farias, Valdigleis S. Costa, Luiz Ranyer A. Lopes +2
In this paper we propose a special type of aggregation function which generalizes the notion of Ordered Weighted Averaging Function - OWA. The resulting functions are called Dynami…
