WebMar 18, 2015 · 3 Answers. In general the naive Bayes classifier is not linear, but if the likelihood factors p ( x i ∣ c) are from exponential families, the naive Bayes classifier corresponds to a linear classifier in a particular feature space. Here is how to see this. p ( c = 1 ∣ x) = σ ( ∑ i log p ( x i ∣ c = 1) p ( x i ∣ c = 0) + log p ( c = 1 ...
