• #### Some ideas concerning fuzzy intelligent systems ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
This article brings together some ideas on fuzzy intelligent systems. We start from fuzzy controllers, and we reflect on the role of fuzzy logic in other domains in which, in spite of optimistic forecasts, advances made ...
• #### The limits of fuzzy logic ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
In this paper we try to answer to the following questions: What can be made by applying fuzzy logic? and What can not be made by applying fuzzy logic? The question will be analyzed from both theoretical and applied point ...
• #### Towards a fuzzy computability? ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
The subject of the present paper is the study of fuzzy computability based on fuzzy Turing machines. Two different models of fuzzy Turing machines will be discussed. It is shown that most work on fuzzy mathematics may be ...
• #### Some practical problems in fuzzy sets-based decision support systems ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
In this paper some problems arising in the interface between two different areas, Decision Support Systems and Fuzzy Sets and Systems, are considered. The Model-Base Management System of a Decision Support System which ...
• #### Truth and utility in fuzzy logic ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
The notion of degree of truth used in fuzzy logic can be interpreted in terms of partial truth or in terms of utility. By investigating how these interpretations fit in with Tarski's definition of truth, this paper ...
• #### A reflection on what is a membership function ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
This paper is just a first approach to the idea that the membership function $\mu _{P}$ of a fuzzy set labelled $P$ is, basically, a measure on the set of linguistic expressions $x$ is $P"$ for each $x$ in the corresponding ...
• #### Putting together Łukasiewicz and product logics ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
In this paper we investigate a propositional fuzzy logical system $\L\Pi$ which contains the well-known \L ukasiewicz, Product and G\"{o}del fuzzy logics as sublogics. We define the corresponding algebraic structures, ...
• #### Idempotent operators on a finite chain ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
This work is devoted to find and study some possible idempotent operators on a finite chain $L$. Specially, all idempotent operators on $L$ which are associative, commutative and non-decreasing in each place are ...
• #### On the learning of weights in some aggregation operators: the weighted mean and OWA operators ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
We study the determination of weights for two types of aggregation operators: the weighted mean and the OWA operator. We assume that there is at our disposal a set of examples for which the outcome of the aggregation ...
• #### Method of least squares applied to the generalized modus ponens with interval-valued fuzzy sets ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
Firstly we present a geometric interpretation of interval-valued fuzzy sets. Secondly, we apply the method of least squares to the fuzzy inference rules when working with these sets. We begin approximating the lower and ...
• #### Inference of fuzzy regular grammars from examples ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
Let us consider the following situation: An oracle provides us with a finite set of examples considered as words belonging to a regular language. This oracle is not available again. In this paper we study a new and general ...
• #### On the global stability of Takagi-Sugeno general model ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
Global stability of Takagi-Sugeno (T-S) fuzzy model is presented. First, stability conditions for T-S fuzzy model presented by Tanaka and Sugeno are reviewed. Second, new theorems for the stability of the general form of ...
• #### Formal Validation of Fuzzy Control Techniques. Perspectives ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
In this paper, a survey of the state of the art and perspectives of two main lines of research in fuzzy control systems is presented: on one hand, the \emph{interpolative-functional line} representing fuzzy systems as ...
• #### Fast prototyping of computing-oriented fuzzy logic systems ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
In this paper we propose to explore different dedicated hardware solutions in terms of area-speed trade-offs for computing-oriented fuzzy logic systems in the algorithmic abstraction level that fulfil the application ...
• #### A mixed-signal architecture for high complexity CMOS fuzzy controllers ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obert
Analog circuits provide better area/power efficiency than their digital counterparts for low-medium precision requirements [1]. This limit in precision, as well as the lack of design tools when compared to the digital ...
