The code and datasets to reproduce the results in this paper are publicly avail-able. 1 ... 2.1 Multinomial Naive Bayes (MNB) In MNB, x(k) = f(k), w = rand b= log(N +=N). N +;N are the number of positive and negative training cases. However, as in (Metsis et al., 2006), WebMar 31, 2024 · Bernoulli Naive Bayes This is used when features are binary. So, instead of using the frequency of the word, if you have discrete features in 1s and 0s that represent the presence or absence of a feature. In that case, the features will be binary and we will use Bernoulli Naive Bayes.
