Betting on Fuzzy and Many-valued Propositions

چکیده
In a 1968 article, ‘Probability Measures of Fuzzy Events’, Lotfi Zadeh proposed accounts of absolute and conditional probability for fuzzy sets (Zadeh, 1968). Where P is an ordinary (“classical”) probability measure defined on a σ-field of Borel subsets of a space X, and μA is a fuzzy membership function defined on X, i.e. a function taking values in the interval [0, 1], the probability of the fuzzy set A is given by

Interval-Valued Fuzzy Propositions. An Application to the L-Fuzzy Contexts with Absent Values
In order to obtain the information from an L-Fuzzy context, the complete relation between the objects and the attributes is needed. However, the contexts that model many situations have absent values. To solve this problem, at the beginning of the paper we remind the interval-valued linguistic variable definition and, later, we propose an extension of the fuzzy propositions to the interval-valu...
متن کاملModalities and many-valued: modelling uncertainty measures and similarity-based reasoning and application to Fuzzy description Logics
The talk will began remembering results on papers [22, 15, 16] where the authors model uncertainty measures as fuzzy modalities on a many-valued residuated logics. the basic idea is that uncertainty measures is not a truth degree but could be interpreted as a truth degree of the fuzzy sentence ”the probability of φ”. The main properties being that the language does not allow nested modalities a...
متن کاملFrom Games to Truth Functions: A Generalization of Giles's Game
Motivated by aspects of reasoning in theories of physics, Robin Giles defined a characterization of infinite valued Lukasiewicz logic in terms of a game that combines Lorenzen-style dialogue rules for logical connectives with a scheme for betting on results of dispersive experiments for evaluating atomic propositions. We analyze this game and provide conditions on payoff functions that allow us...
متن کاملLogics for Representation of Propositions with Fuzzy Modalities
In the paper we introduce logical calculi for representation of propositions with modal operators indexed by fuzzy values. There calculi are called Heyting-valued modal logics. We introduce the concept of a Heyting-valued Kripke model and consider a semantics of Heyting-valued modal logics at the class of Heyting-valued Kripke models.
متن کاملOn the relationship between fuzzy logic and four-valued relevance logic
In fuzzy propositional logic, to a proposition a partial truth in [0; 1] is assigned. It is well known that under certain circumstances, fuzzy logic collapses to classical logic. In this paper, we will show that under dual conditions, fuzzy logic collapses to four-valued (relevance) logic, where propositions have truth-value true,false, unknown, or contradiction. As a consequence, fuzzy entailm...
