Sensitivity Analysis

The sensitivity analysis engine allows users to specify constraints on network queries and will then identify minimal parameter changes that are necessary to satisfy these constraints. This functionality is essential for model debugging, which requires an understanding of the relationship between local parameters that quantify a Bayesian network, and global conclusions drawn from the network.

The sensitivity analysis engine of SamIam is based on [UAI01:CD, JAIR02:CD, AAAI02:CD]. SamIam is currently the only tool of this scope which provides an engine for sensitivity analysis in Bayesian networks.
