On V-projections of possibility distributions
Vejnarová, Jiřina
We introduce the notion of total variance of two possibility distributions and the projection of a possibility distribution on a set of possibility distributions with respect to it.
Two applications of Bayesian networks
Vomlel, Jiří
We present two recent applications of Bayesian networks: adaptive testing and troubleshooting man-made devices. We review briefly the underlying theory and provide a general framework for building strategies using Bayesian network models. We discuss applications of the framework to adaptive testing and troubleshooting. The paper is based on our experience with two projects.
Thoughts on belief and model revision with uncertain evidence
Vomlel, Jiří
Bayesian networks and other graphical probabilistic models became a popular framework for reasoning with uncertainty. Efficient methods have been developed for revising beliefs with new evidence. However, when the evidence is uncertain, i.e. represented by a probability distribution, different methods have been proposed. In this paper we analyze and compare these methods. The goal is to show in what cases they can be used correctly.
