Abstract
While Naïve Bayes classifier (NB) is Bayes-optimal for independent features, we prove that it is also optimal for two equiprobable classes and two features with equal class-conditional covariances. Although strict optimality does not extend for three features, equal covariances are expected to be beneficial in higher-dimensional spaces.
