Witryna4 paź 2014 · Oct 4, 2014. by Sebastian Raschka. Naive Bayes classifiers, a family of classifiers that are based on the popular Bayes’ probability theorem, are known for creating simple yet well performing models, especially in the fields of document classification and disease prediction. In this first part of a series, we will take a look at … WitrynaIn a probabilistic classification model we want to estimate the value of P(c x) , the probability of a sample x being of class c. Naive Bayes is one such probabilistic classifier that uses Bayes' Rule to classify samples.
