Initially, the filter takes the previous log odds … WebNaive Bayes is based on the popular Bayesian Machine learning algorithm. It is called as Naive as it assumes that all the predictors in the dataset are independent of each other. Naive Bayes Classifier Algorithm is mostly used for binary and multiclass classification. The formulae for the conditional probability is
