Automated Reasoning Using Possibilistic Logic: Semantics, Belief Revision and Variable Certainty Weights
Didier Dubois, Jerome Lang, Henri Prade
In this paper an approach to automated deduction under uncertainty,based on possibilistic logic, is proposed ; for that purpose we deal with clauses weighted by a degree which is a…
Numerical Representations of Acceptance
Didier Dubois, Henri Prade
Accepting a proposition means that our confidence in this proposition is strictly greater than the confidence in its negation. This paper investigates the subclass of uncertainty m…
Coping with the Limitations of Rational Inference in the Framework of Possibility Theory
Salem Benferhat, Didier Dubois, Henri Prade
Possibility theory offers a framework where both Lehmann's "preferential inference" and the more productive (but less cautious) "rational closure inference" can be represented. How…
Qualitative Decision Theory with Sugeno Integrals
Didier Dubois, Henri Prade, Regis Sabbadin
This paper presents an axiomatic framework for qualitative decision under uncertainty in a finite setting. The corresponding utility is expressed by a sup-min expression, called Su…
