Many real-world applications have very high dimensionality and require very complex decision borders. In this case, the number of fuzzy rules can proliferate, and the easy interpretability of fuzzy models can progressively disappear. An important part of the model interpretation lies on the evaluation of the effectiveness of the input features on the decision process. In this paper, we present ...

Because of the pressure of globalization in the last two decades, professional services has become an important strategic decision so that supplier selection is a prime concern. In the semiconductor industry, the prior researches worked on analyzing and improving the process, and evaluating the equipment manufacturers. Consequently, this study is to identify critical factors related to the wafe...

The returns and risks of high-yield bond (HYB) lie between the stocks and Treasury bonds. In view of investment opportunities and the rate of return, the advantages of HYB are both lower risks and higher shares. Therefore, HYB has become one of important components in the portfolios. The purpose of this study is to identify critical factors related to the selection of HYB. Primary criteria to e...

Whether the design of knowledge base or the modeling of complex systems, when systems are characterized as complex systems with high dimension and a variety of variables and factors, to reduce complexity are necessary. Fuzzy cognitive maps (FCM) are a soft computing method for simulation and analysis of complex system, which combines the fuzzy logic with theories of neural networks. It is flexi...

In this article, the prediction of COVID-19 based on a combination fractal theory and interval type-3 fuzzy logic is put forward. The dimension utilized to estimate time series geometrical complexity level, which in case applied problem. main aim utilizing for handling uncertainty decision-making occurring forecasting. hybrid approach formed by an model structured if then rules that utilize as ...

Your Texture analysis is one of the most important techniques used in the analysis and interpretation of images, consisting of repetition or quasi repetition of some fundamental image elements. The present paper derived Fuzzy Triangular Greylevel Pattern (FTGP) to overcome the disadvantages of LBP and other local approaches. The FTGP is a 2 x 2 matrix that is derived from a 3 x 3 neighborhood m...

The quantum space-time and the phase space of massive particles with Fuzzy Geometry structure investigated as the possible quantization formalism. In this model the state of nonrelativistic particle m corresponds to the element of fuzzy ordered set (Foset)-fuzzy point. Due to its partial ordering m space coordinate x acquires principal uncertainty σ x. It's shown that Fuzzy Mechanics (FM) in 1+...

E-mail’s text is the main body of an E-mail. Its content is reflected by semantic body formed by a large number of semantic elements, so it is the most authoritative and effective to study semantic body information of spam when analyzing its text. Firstly, this paper takes the advantage of HowNet in analysis of semantic element and analyze semantic bodies in email text, then proposes the method...

This work presents a useful extension of Kohonen's Self-Organizing Map (KSOM) for structure identification in linguistic (fuzzy) system modeling applications. More specifically the granular SOM neural model is presented for inducing a distribution of nonparametric fuzzy interval numbers (FINs) from the data. A FIN can represent a local probability distribution function and/or a conventional fuz...
