Influence Diagrams Representation and Analysis of Medical Decision Problems with Influence Diagrams
Influence diagrams are a powerful graphic representation for decision models, complementary to decision trees. Influence diagrams and decision trees are different graphic representations for the same underlying mathematical model and operations. This article describes the elements of an influence diagram, and shows several familiar decision problems represented as decision trees and as influenc...
متن کاملHybrid Influence Diagrams Using Mixtures of Truncated Exponentials
Mixtures of truncated exponentials (MTE) potentials are an alternative to discretization for representing continuous chance variables in influence diagrams. Also, MTE potentials can be used to approximate utility functions. This paper introduces MTE influence diagrams, which can represent decision problems without restrictions on the relationships between continuous and discrete chance variable...

متن کاملA New Decision Making Approach based on Possibilistic Influence Diagrams
This paper proposes a new decision making approch based on quantitative possibilistic influence diagrams which are extension of standard influence diagrams in the possibilistic framework. We will in particular treat the case where several expert opinions relative to value nodes are available. An initial expert assigns confidence degrees to other experts and fixes a similarity threshold that pro...
متن کاملIssues in Bayes Nets and Influence Diagrams: With Applications in Accounting and Auditing
Recently substantial research in artificial intelligence (AI) has focused on Bayes nets and the closely related influence diagrams. However, there has been little work in the accounting and auditing communi ties in this area of AI research. Bayes nets and influence diagrams have some advantages over deterministic AI approaches. These approaches employ probabilities to model decision making. Pr...
