WebBayesian belief nets (BNs) are often used for classification tasks—typically to return the most likely class label for each specified instance. Many BN-learners, however, attempt to find the BN that maximizes a different objective function—viz., likelihood, rather than classification accuracy—typically by first learning an appropriate graphical structure, then … WebComparing Bayesian Network Classifiers Jie Cheng Russell Greiner Department of Computing Science University of Alberta Edmonton, Alberta T6G 2H1 Canada Email: {jcheng, greiner}@cs.ualberta.ca Abstract In this paper, we empirically evaluate algorithms for learning four Bayesian network (BN) classifiers: Naïve-Bayes, tree augmented
