RT Journal Article T1 Sensitivity to evidence in Gaussian Bayesian networks using mutual information A1 Gómez Villegas, Miguel A. A1 Main Yaque, Paloma A1 Viviani, Paola AB We introduce a methodology for sensitivity analysis of evidence variables in Gaussian Bayesian networks. Knowledge of the posterior probability distribution of the target variable in a Bayesian network, given a set of evidence, is desirable. However, this evidence is not always determined; in fact, additional information might be requested to improve the solution in terms of reducing uncertainty. In this study we develop a procedure, based on Shannon entropy and information theory measures, that allows us to prioritize information according to its utility in yielding a better result. Some examples illustrate the concepts and methods introduced.
