4. Bayesian Network Bayesian Belief Network based system Bayesian Belief Network based system MSBN - Multiple sectioned Bayesian network MSBN - Multiple sectioned Bayesian network Uses natural localization existing in domain to decrease computational costUses natural localization existing in domain to decrease computational cost Also limits outcomes not anatomically involvedAlso limits outcomes not anatomically involved

5. Bayesian Network Contains 83 variables representing 14 diseases and 69 features, each of which has 3 possible outcomes.
