Theory refinement on bayesian networks
Webb1 okt. 2009 · This paper examines the performance of Bayesian networks as classifiers, comparing their performance to that of the Naïve Bayes (NB) classifier and the Tree Augmented Naïve Bayes (TAN) classifier, both of which make strong assumptions about interactions between domain variables. WebbThis dissertation presents Banner, a technique for using data to revise a given Bayesian network with Noisy-Or and Noisy-And nodes, to improve its classification accuracy. …
