On possibilistic marginal problem
A possibilistic marginal problem is introduced in a way analogous to probabilistic framework, to address the question of whether or not a common extension exists for a given set of marginal distributions. Similarities and differences between possibilistic and probabilistic marginal problems will be demonstrated, concerning necessary condition and sets of all solutions. The operators of composit...
متن کاملNovel Bounds on Marginal Probabilities
We derive two related novel bounds on single-variable marginal probability distributions in factor graphs with discrete variables. The first method propagates bounds over a subtree of the factor graph rooted in the variable, and the second method propagates bounds over the self-avoiding walk tree starting at the variable. By construction, both methods not only bound the exact marginal probabili...
متن کاملBounds on marginal probability distributions
We propose a novel bound on single-variable marginal probability distributions in factor graphs with discrete variables. The bound is obtained by propagating local bounds (convex sets of probability distributions) over a subtree of the factor graph, rooted in the variable of interest. By construction, the method not only bounds the exact marginal probability distribution of a variable, but also...
متن کاملA Note on Marginal Deterrence
The theory of deterrence has been concerned primarily with situations in which individuals consider whether to commit a single harmful act. For instance, a person may be deciding whether to discharge a pollutant into a lake. In some contexts, however, a person may be contemplating which of several harmful acts to commitwhether to discharge a pollutant into a lake or instead to discharge it onto...
متن کاملComparison between deep chamfer and 135 ̊ tooth preparation designs on marginal fit and marginal gap in posterior metal-ceramic crowns
Background and Aims: One of the most important challenges for dentists is providing a crown with appropriate marginal fit and gap. The 135-degree tooth preparation found to have some advantages such as technical ease and appropriate finish line record. Despite the advantages of 135-degree tooth preparation, scant research has been done in this area. Therefore, the aim of this study was to compa...
