Evenly Convex Credal Sets
نویسنده
چکیده
An evenly convex credal set is a set of probability measures that is evenly convex; that is, a set that is an intersection of open halfspaces. An evenly convex credal set can for instance encode preference judgments through strict and non-strict inequalities such as P (A) > 1/2 and P (A) ≤ 2/3. This paper presents an axiomatization of evenly convex sets from preferences, where we introduce a new (and very weak) Archimedean condition.

Credal Compositional Models and Credal Networks
This paper studies the composition operator for credal sets introduced at the last ISIPTA conference in more detail. Our main attention is devoted to the relationship between a special type of compositional model, so-called perfect sequences of credal sets, and those of (precise) probability distributions, with the goal of finding the relationship between credal compositional models and credal ...
متن کاملA Non-specificity Measure for Convex Sets of Probability Distributions
There is an error in the proof of the subadditivity property of IG function on credal sets in the paper "A Non-specificity Measure for Convex Sets of Probability Distributions". The proof is based on the inclusion C C CH(Cx x Cy) which is not always true, being C a credal set on a finite set 1 x 7 ; Cx,Cy its marginal credal sets on X and Y, respectively, and CH the convex hull. The subadditivi...
متن کاملCredal Sets Approximation by Lower Probabilities: Application to Credal Networks
Credal sets are closed convex sets of probability mass functions. The lower probabilities specified by a credal set for each element of the power set can be used as constraints defining a second credal set. This simple procedure produces an outer approximation, with a bounded number of extreme points, for general credal sets. The approximation is optimal in the sense that no other lower probabi...
متن کاملAdditivity of uncertainty measures on credal sets
A general way of representing incomplete information is to use closed and convex sets of probability distributions, which are also called credal sets. Each credal set is associated with uncertainty, whose amount is quantified by an appropriate uncertainty measure. One of the requisite properties of uncertainty measures is the property of additivity, which is associated with the concept of indep...
متن کاملFinite approximations to coherent choice
This paper studies and bounds the effects of approximating loss functions and credal sets on choice functions, under very weak assumptions. In particular, the credal set is assumed to be neither convex nor closed. The main result is that the effects of approximation can be bounded, although in general, approximation of the credal set may not always be practically possible. In case of pairwise c...
