Generating Hasse trees of fuzzy preorder closures: an algorithmic approach
نویسندگان
چکیده
Mathematical theories are pervaded with the use of partial orders and more general preorders also called quasi orders i e re exive and transitive binary rela tions Preorders also play an important role in appli cations for instance as preference relations in multi criteria decision aid techniques The observation that classical relations do not allow to express partial or graded relationships has led to the introduction of fuzzy relations In preference modelling for instance fuzzy relations are used to express graded preferences indi erences and incomparabilities

Lattices for 3-Dimensional Fuzzy Data generated by Fuzzy Galois Connections
Vagueness and high dimensional space data are usual features of current data. The paper is an approach to identify conceptual structures among fuzzy three dimensional data sets in order to get conceptual hierarchy. We propose a fuzzy extension of the Galois connections that allows to demonstrate an isomorphism theorem between fuzzy sets closures which is the basis for generating lattices ordere...
متن کاملGeneration and Characterization of Fuzzy T-preorders
This paper studies T -preorders than can be generated in a natural way by a single fuzzy subset. These T -preorders are called one-dimensional and are of great importance, since every T -preorder can be generated by combining onedimensional ones. In the paper, the relation between fuzzy subsets generating the same T -preorder is given and one-dimensional T -preorders are characterized in two di...
متن کاملAn algorithmic approach for fuzzy inference
To apply fuzzy logic, two major tasks need to be performed: the derivation of production rules and the determination of membership functions. These tasks are often difficult and time consuming. This paper presents an algorithmic method for generating membership functions and fuzzy production rules; the method includes an entropy minimization for screening analog values. Membership functions are...
متن کاملNormalizing Possibility Distributions Using t-Norms
A new approach to normalizing fuzzy sets is introduced where it is assumed that the normalization method is compatible with a given t-norm. In this context it is proved that the most usual ways to normalize fuzzy subsets correspond to the most common t-norms. For a given fuzzy subset μ, the corresponding normalized fuzzy subset μ̂ can be viewed as the distribution of μ conditioned on the (degree...
متن کاملTOPOLOGICAL SIMILARITY OF L-RELATIONS
$L$-fuzzy rough sets are extensions of the classical rough sets by relaxing theequivalence relations to $L$-relations. The topological structures induced by$L$-fuzzy rough sets have opened up the way for applications of topological factsand methods in granular computing. In this paper, we firstly prove thateach arbitrary $L$-relation can generate an Alexandrov $L$-topology.Based on this fact, w...
