Two measures that quantify distinguishability of fuzzy sets are addressed in this paper: similarity, which exhibits sound theoretical properties but it is usually computationally intensive, and possibility, whose calculation can be very efficient but does not exhibit the same properties of similarity. It is shown that under mild conditions – usually met in interpretable fuzzy modelling – possib...
Different methods have been proposed for finding the non-negative solution of fully fuzzy linear system (FFLS) i.e. fuzzy linear system with fuzzy coefficients involving fuzzy variables. To the best of our knowledge, there is no method in the literature for finding the non-negative solution of a FFLS without any restriction on the coefficient matrix. In this paper a new computational method is ...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
Data mining, also known as knowledge discovery in database, is the process to discover unknown knowledge from a large amount of data. Text mining is to apply data mining techniques to extract knowledge from unstructured text. Text clustering is one of important techniques of text mining, which is the unsupervised classification of similar documents into different groups. The most important step...
This research aims to determine the maximum or minimum value of a Fuzzy Support Vector Machine (FSVM) Algorithm using optimization function. SVM is considered as an effective method data classification, opposed FSVM, which less on large and complex because its sensitivity outliers noise. One techniques used overcome this inefficiency fuzzy logic with ability select right membership function, si...
First, Similarity Of Fuzzy Ontology Generation For Semantic Web, Fuzzy Formal Concept Analysis incorporates fuzzy logic into Formal Concept Analysis (FCA) to form a fuzzy concept lattice. The fuzzy ontology is an extension of the domain ontology for solving the uncertainty problems. Fuzzy Conceptual Clustering then constructs the concept hierarchy from the fuzzy concept lattice. Finally, Fuzzy ...
This contribution aims at the dissemination of a similarity-based generalization of fuzzy orderings, however, not from a purely theoretical perspective, but from the viewpoint of possible practical applications. After a short motivation of similarity-based fuzzy orderings, we consider four case studies with the aim to illustrate the application potential of fuzzy orderings—flexible query answer...
Fuzzy similarity measure is very useful in fuzzy information retrieval. This study presents a new method based on fuzzy-number similarity measure to deal with fuzzy information retrieval problems. The proposed method can obtain the suitable retrieval results for the user because it translate the degree of satisfaction F~ into a linguistic term, and user can easily determine whether the retrieve...
