In this paper, we propose a scalar variable formation of fuzzy regression model based on the axiomatic credibility measure foundation. The fuzzy estimation for fuzzy regression coefficients is investigated. A general M-estimation criterion is developed under Maximum Fuzzy Uncertainty Principle, which resulted in weighted Normal equation with adjusted term for M-estimator of the regression coeff...

This paper introduces a novel intuitionistic fuzzy set-based heuristic algorithm of possibilistic clustering. For the purpose, some remarks on the fuzzy approach to clustering are discussed and a brief review of intuitionistic fuzzy set-based clustering procedures is given, basic concepts of the intuitionistic fuzzy set theory and the intuitionistic fuzzy generalization of the heuristic approac...

Recently there has been growing interest in building “active” visual object recognizers, as opposed to “passive” recognizers which classifies a given static image into a predefined set of object categories. In this paper we propose to generalize recent end-to-end active visual recognizers into a controller-recognizer framework. In this framework, the interfaces with an external manipulator, whi...

A new concept to the optimization problem in an intuitionistic fuzzy environment is introduced. A general model, of linear programming problems in which both the right hand side constants and the technological coefficients are intuitionistic fuzzy numbers, has been presented. An attempt has been made to find a general linear non-membership function and intuitionistic fuzzy index together with t...

A time-varying Weiner filter extracts the speech signal from a noisy mixture using the a priori signal-to-noise ratio in a local time-frequency unit. We estimate this ratio using a binaural processor and derive a ratio time-frequency mask. This mask is used to extract the speech signal, which is then fed to a conventional speech recognizer operating in the cepstral domain. We compare the perfor...

To build a very large vocabulary (50K) isolated word speech recognizer, speech data from over 200 native speakers of American English was recorded and manually transcribed. This paper explains the transcription method used, the motivation, and preliminary results implemented in the recognizer. The symbol set was expanded to allow for narrow phonetic transcriptions, similar to the level of detai...

Closure operators (and closure systems) play a significant role in both pure and applied mathematics. In the framework of fuzzy set theory, several particular examples of closure operators and systems have been considered (e.g. so-called fuzzy subalgebras, fuzzy congruences, fuzzy topology etc.). Recently, fuzzy closure operators and fuzzy closure systems themselves (i.e. operators which map fu...

Faculty of Technology Department of Informatics by Majid Almaraashi This thesis reports the work of using simulated annealing to design more efficient fuzzy logic systems to model problems with associated uncertainties. Simulated annealing is used within this work as a method for learning the best configurations of type-1 and type-2 fuzzy logic systems to maximise their modelling ability. There...

This paper constitutes a re nement of the fuzzy uni cation algorithm based on fuzzy compatibility relations, which we have developed with the aim of including the data type fuzzy set in a logic programming environment which supports a family of in nitely-valued logics. To be precise, we treat the problem of fuzzy uni cation by focusing on the distinction between general and speci c knowledge. F...
