In the proposed framework, belief-dependent concepts such as the strategy with the best expected value are formally derivable in higher-order fuzzy logic for any finite matrix game with rational payoffs.

Fuzzy logic

The comparison could be made on very different levels, that is, mathematically, semantically, linguistically, and so on. Fuzzy set theory is not or is no longer a uniquely defined mathematical structure, such as Boolean algebra or dual logic. It is rather a very general family of theories consider, for instance, all the possible operations defined in chapter 3 or the different types of membership functions. In this respect, fuzzy set theory could rather be compared with the different existing theories of multivalued logic. Unable to display preview. Download preview PDF. Skip to main content.

Possibility Theory,Probability Theory,and Fuzzy Set Theory

Fuzzy evidence theory, or fuzzy Dempster-Shafer Theory captures all three types of uncertainty, i. Therefore, it is known as one of the most promising approaches for practical applications. Quantifying the difference between two fuzzy bodies of evidence becomes important when this framework is used in applications. This work is motivated by the fact that while dissimilarity measures have been surveyed in the fields of evidence theory and fuzzy set theory, no comprehensive survey is yet available for fuzzy evidence theory. We proposed a modification to a set of the most discriminative dissimilarity measures smDDM -as the minimum set of dissimilarity with the maximal power of discrimination in evidence theory- to handle all types of uncertainty in fuzzy evidence theory. The generalized smDDM FsmDDM together with the one previously introduced as fuzzy measures make up a set of measures that is comprehensive enough to collectively address all aspects of information conveyed by the fuzzy bodies of evidence.

In fuzzy mathematics , fuzzy logic is a form of many-valued logic in which the true values of variables may be any real number between 0 and 1 both inclusive. It is employed to handle the concept of partial truth, where the true value may range between completely true and completely false. The term fuzzy logic was introduced with the proposal of fuzzy set theory by Lotfi Zadeh. Fuzzy logic is based on the observation that people make decisions based on imprecise and non-numerical information. Fuzzy models or sets are mathematical means of representing vagueness and imprecise information hence the term fuzzy. These models have the capability of recognising, representing, manipulating, interpreting, and utilising data and information that are vague and lack certainty.

Fuzzy logic has been employed to handle the concept of partial truth, where the truth value may range between completely true and completely false. The term fuzzy logic was introduced with the proposal of fuzzy set theory by Lotfi Zadeh. Fuzzy logic has been applied to many fields, from control theory to artificial intelligence. Classical logic only permits conclusions which are either true or false. However, there are also propositions with variable answers, such as one might find when asking a group of people to identify a colour.


Moreover, suggestions and examples of how to extend the formalism to cope with conditional probabilities and with other uncertainty formalisms are also provided.


Fuzzy and Probability Uncertainty Logics

The chapters, written by pioneers and prominent scholars in the field, show how fuzzy sets have been successfully applied to artificial intelligence, control theory, inference, and reasoning. The book also reports on theoretical issues; features recent applications of Fuzzy Logic in the fields of neural networks, clustering, data mining, and software testing; and highlights an important paradigm shift caused by Fuzzy Logic in the area of uncertainty management.

A probabilistic fuzzy logic system for modeling and control Abstract: In this paper, a probabilistic fuzzy logic system PFLS is proposed for the modeling and control problems.

Действуй, объясняться будешь. Чатрукьян знал, что ему делать. Знал он и то, что, когда пыль осядет, он либо станет героем АНБ, либо пополнит ряды тех, кто ищет работу. В огромной дешифровальной машине завелся вирус - в этом он был абсолютно уверен.

 У нас вирус. Затем раздался крик: - Нужно немедленно вызвать Джаббу. Послышались другие звуки, похожие на шум борьбы. ГЛАВА 55 - Ты уселся на мое место, осел. Беккер с трудом приподнял голову. Неужели в этой Богом проклятой стране кто-то говорит по-английски.

О Боже… Сьюзан. Впервые с детских лет Беккер начал молиться. Он молился не об избавлении от смерти - в чудеса он не верил; он молился о том, чтобы женщина, от которой был так далеко, нашла в себе силы, чтобы ни на мгновение не усомнилась в его любви. Он закрыл глаза, и воспоминания хлынули бурным потоком. Он вспомнил факультетские заседания, лекции - все то, что заполняло девяносто процентов его жизни. Вспомнил о Сьюзан.


cross-roads between fuzzy sets and probability theory. iii). Mathematical objects that recently built up under the name of Lebesgue logic (Bennett. et al. [5]). membership grades pervades the literature of uncertainty in.


Он перечитал свою записку и положил на пол возле. То, что он собирался сделать, несомненно, было проявлением малодушия. Я умею добиваться своей цели, - подумал. Потом он подумал о вирусе, попавшем в ТРАНСТЕКСТ, о Дэвиде Беккере в Испании, о своих планах пристроить черный ход к Цифровой крепости. Он так много лгал, он так виноват. Стратмор знал, что это единственный способ избежать ответственности… единственный способ избежать позора.

Звонки в агентства услуг сопровождения ничего не дали. Коммандер, недовольный необходимостью говорить по линии, не защищенной от прослушивания, попросил Дэвида не звонить, пока кольцо не окажется в его руках. Он решил было обратиться в полицию - может быть, у них есть данные о рыжеволосых проститутках, - но Стратмор на этот счет выразился недвусмысленно: Вы должны оставаться невидимым. Никто не должен знать о существовании кольца. Может быть, стоит побродить по Триане, кварталу развлечений, и поискать там эту рыжую девицу. Или же обойти все рестораны - вдруг этот тучный немец окажется .

 - Подслушивающий должен был находиться в непосредственной близости и точно знать, что надо подслушивать.  - Он положил руку ей на плечо.  - Я никогда не послал бы туда Дэвида, если бы считал, что это связано хоть с малейшей опасностью.

    The aim of a probabilistic logic also probability logic and probabilistic reasoning is to combine the capacity of probability theory to handle uncertainty with the capacity of deductive logic to exploit structure of formal argument.
