Naive Bayes Classifiers

 · Naive Bayes classifiers are a collection of classification algorithms based on Bayes'' Theorem. It is not a single algorithm but a family of algorithms where all of them share a common principle, i.e. every pair of features being classified is independent of each other. To start with, let us consider a dataset.
