introduction bacterial meningitis is a known infectious disease which occurs at early ages and should be promptly diagnosed and treated. bacterial and aseptic meningitis are hard to be distinguished. therefore, physicians should be highly informed and experienced in this area. the main aim of this study was to suggest a system for distinguishing between bacterial and aseptic meningitis, using f...

Fuzzy control is a methodology that translates “if”-“then” rules Aj1(x1) & ... & Ajn(xn) → Bj(u) formulated in terms of a natural language, into an actual control strategy u(x⃗). Implication of uncertain statements is much more difficult to understand than “and”, “or”, and “not”. So, the fuzzy control methodologies usually start with translating “if”-“then” rules into statements that contain onl...

This article is a reaction to recent publications on rulebased modeling using fuzzy set theory and fuzzy logic. The interest in fuzzy systems has recently shifted from the seminal ideas about complexity reduction toward data-driven construction of fuzzy systems. Many algorithms have been introduced that aim at numerical approximation of functions by rules, but pay little attention to the interp...

This paper is concerned with the application of a treebased regression model to extract fuzzy rules from highdimensional data. We introduce a locally weighted scheme to the identification of Takagi-Sugeno type rules. It is proposed to apply the sequential least-squares method to estimate the linear model. A hierarchical clustering takes place in the product space of systems inputs and outputs a...

In this paper we develop a fuzzy image filter which consists of a multi-layered fuzzy structure based on the weighted fuzzy blend filter for the removal of noise from images heavily corrupted by impulse noise, while preserving the intricate details of the image. The introduction of multi-layered fuzzy systems substantially decreases the number of rules to be learnt. We then show how Evolutionar...

This paper provides a logical basis for manipulation with fuzzy IF-THEN rules. Our theory is wide enough and it encompasses not only finding a conclusion by means of the compositional rule of inference due to Lotfi A. Zadeh but also other kinds of approximate reasoning methods, e.g. perception-based deduction, provided that there exists a possibility to characterize them within a formal logical...
