    Most fuzzy modeling algorithms rely either on simplistic (grid type) or off-line (trial-and-error type) structure identification methods. The proposed neurofuzzy modeling architecture, NeuroFAST, is an on-line, structure and parameter learning algorithm, featuring high function approximation accuracy. It is based on the first order Takagi-Sugeno-Kang (TSK) model (functional reasoning), where the c... View full abstract»

    Modern information retrieval systems match the terms included in a user's query with available documents, through the use of an index. A fuzzy thesaurus is used to enrich the query with associated terms. In this work, we use semantic entities, rather than terms; this allows us to use knowledge stored in a semantic encyclopedia, specifically the ordering relations, in order to perform a semantic ex...

    The genetic algorithms are heuristics and thus they do not ensure an optimal solution. We propose to use a fuzzy controller for an improvement of genetic algorithms. The speed of natural evolution is changeable. Genetic algorithms can be classified into three main categories: a basic GA, evolution strategies, and a mobile GA. The mobile GA has a variable chromosome structure. The aim of this paper... View full abstract»
