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…
A Unified framework for order-of-magnitude confidence relations
Didier Dubois, Helene Fargier
The aim of this work is to provide a unified framework for ordinal representations of uncertainty lying at the crosswords between possibility and probability theories. Such confide…
A unified setting for inference and decision: An argumentation-based approach
Leila Amgoud
Inferring from inconsistency and making decisions are two problems which have always been treated separately by researchers in Artificial Intelligence. Consequently, different mode…
