Numerical experimentation and comparison of fuzzy integral
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessSugeno and Choquet integrals have been widely studied in the literature from a theoretical viewpoint. However, the behavior of these functionals is known in a general way, but not in practical applications and in particular ... -
Concept lattices associated with L-Fuzzy W-contexts
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open Access\begin{abstract} \noindent We generalize in this paper the $L$-Fuzzy concept theory we developed in a previous paper ([1]), using the composition of $L$-Fuzzy relations. This theory models knowledge acquisition ... -
The fuzzy hyperbolic inequality index on fuzzy random variables in finite populations
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessThis paper presents an approach to the problem of quantifying the in-equality of a finite population with respect to a (social, economical, etc.) fuzzy-valued attribute. For this purpose, the fuzzy hyperbolic inequality ... -
Representation of fuzzy knowledge bases using Petri nets: operation in the truth space
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessIn this paper the execution of Fuzzy Knowledge Bases in the truth space is briefly analyzed. The computational efficiency of the process is significantly increased by means of a parameterized description based on the ... -
Using fuzzy similiarity relations to revise and update a knwoledge base
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessSimilarity-based models were first used by Ruspini to give semantics to fuzzy logic ([7]). In these models, incomplete information is represented by an evidential set, i.e. a set of possible worlds that are compatible ... -
Neural methods for obtaining fuzzy rules
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessIn previous papers, we presented an empirical methodology based on Neural Networks for obtaining fuzzy rules which allow a system to be described, using a set of examples with the corresponding inputs and outputs. Now ... -
A dual approach in fuzzy linear programming
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessIn this paper, we propose a relationship of fuzzy duality. We use the Decomposition Theorem and some properties about Linear Programming with interval coefficients to define this relationship. Thus, a linear programming ... -
Phrase structure grammars for the expression of vague voncepts in Spanish
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessThis paper characterizes grammars generating Spanish sentences of imprecise meaning. The basic grammar generating sentences onforming to the standard paradigm of fuzzy logic (Quantifier + Noun + Verb + Modifier + Adjective) ... -
Contributions to the symbolic processing of segments in computer vision
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessIn this paper a processing methodology is introduced for the segment or intermediate level in the context of knowledge-based computer vision systems. The proposed methodology demonstrates how using simple Fuzzy Logic ... -
Client/server architecture for fuzzy relational databases
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessThis paper shows a FRDBMS architecture whose main characteristics are: 1) it is implemented entirely on classical RDBMS just using the resources provided by them, 2) it preserves all the operations and qualities of the ... -
Automatic synthesis of fuzzy logic controlers
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessThis paper describes a design environment for the hardware realizations of fuzzy controllers which includes a set of CAD tools to ease the description, verification and synthesis of this kind of systems. Special emphasis ... -
Learning under hardware restrictions in CMOS fuzzy controlers able to extract rules from examples
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open AccessFuzzy controllers are able to incorporate knowledge expressed in if-then rules. These rules are given by experts or skilful operators. Problems arise when there are not experts or/and rules are not easy to find. Authors' ... -
