Evidence and scenario sensitivities in naive Bayesian classifiers
2008
International Journal of Approximate Reasoning
Preserved Fulltext
Empirical evidence shows that naive Bayesian classifiers perform quite well compared to more sophisticated network classifiers, even in view of inaccuracies in their parameters. ...
In this paper, we study the effects of such parameter inaccuracies by investigating the sensitivity functions of a naive Bayesian classifier. ...
Although it is applicable to Bayesian networks in general, in this section we discuss scenario sensitivity in the context of naive Bayesian classifiers. ...
