Powers with respect to t-norms and t-conorms and Aggregation Functions
(Springer, 2016)
Capítol de llibre
Accés restringit per política de l'editorialAggregation functions A stable with respect to powers of t-norms and t-conorms (i.e.: satisfying A(x^{(r)},y^{(r)})=(A(x,y))^{(r)}) where x^{(r)} is the r-th power of x \in [0,1] with respect to a t-norm or t-conorm) are ... -

Reduction of attributes in averaged similarities
(2018-02-01)
Article
Accés obertSimilarity Relations may be constructed from a set of fuzzy attributes. Each fuzzy attribute generates a simple similarity, and these simple similarities are combined into a complex similarity afterwards. The Representation ... -

Searching for meaning on defuzzification
(1999-10)
Article
Accés restringit per política de l'editorialDefuzzification is an essential problem in fuzzy systems that it is always solved in a heuristic way. The aim of this work is to give a semantic interpretation to this process with the help of indistinguishability operators -
Some properties concerning the quasi-inverse of a t-norm
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
Article
Accés obertSome properties of the quasi-inverse operators are presented. They are basic tools in order to reduce complex expressions involving several of such operators. An effective calculation for the quasi-inverse of a continuous ... -

The Length and Betweenness Relations of Indistinguishability Operators
(1999-06)
Article
Accés restringit per política de l'editorialThe most common ways used to generate indistinguishability operators, namely as transitive closure of reexive and symmetric fuzzy relation, via the Representation Theorem and as decomposable relations, is related for ... -
Transitive closure and betweenness relations
(2001-06)
Article
Accés restringit per política de l'editorialIndistinguishability operators fuzzify the concept of equivalence relation and have been proved a useful tool in theoretical studies as well as in di0erent applications such as fuzzy control or approximate reasoning. One ... -

Transitivity of fuzzy relations under discretization
(2013-07-10)
Article
Accés restringit per política de l'editorialFuzzy transitivity is a key property for many fuzzy relational structures, such as fuzzy preorders and equivalences. Theoretical models for practical problems which are based on fuzzy relations make use of continuous scales, ... -
Upper and Lower Approximations of Fuzzy Sets
(2000-09)
Article
Accés restringit per política de l'editorialThe upper and lower approximations of a fuzzy subset with respect to an indistinguish-ability operator are studied. Their relations with fuzzy rough sets are also investigated -
Vague and fuzzy t-norms and t-conorms
(2021-01-01)
Article
Accés obertt-norms and t-conorms are the natural connectives “and” and “or” in fuzzy logic. The unit interval with a t-norm or a t-conorm is a special monoid and some submonoids like discrete t-norms and t-conorms have been proved ...
