WebOct 10, 2024 · The straightforward answer is: Naive Bayes is a generative type of classifier. But this information is not enough. We should also know what a generative type of classifier is. Generative: This type of classifier learns from the model that generates the data behind the scene by estimating the distribution of the model.
