Automated entry of conditional probability data for a decision support apparatus that uses a Bayesian belief network

摘要

A computer implemented method for filling in conditional probability data in a Bayesian Belief network based decision support apparatus is provided. The conditional probability data defines conditional probabilities of states of a particular network node as a function of vectors of state values of a set of parent nodes of the particular network node in the Bayesian Belief network. The computer implemented method comprising receiving conditional probability data defining the conditional probabilities for a subset of all possible vectors of combinations of state values of the set of parent nodes and interpolating conditional probability data defining the conditional probabilities for further possible vectors of state values of the set of parent nodes from the elicited conditional probability data.
