In this paper, the authors propose a hybrid system of SMS classification to detect spam or ham, using Naive Bayes classifier and Apriori algorithm.

Naive Bayes Classification: A probabilistic model that applies Bayes’ theorem assuming conditional independence among features, used extensively for its efficiency and interpretability.

General naive Bayes classification is a classical machine learning technique to predict a discrete value. There are several variations of naive Bayes (NB) including Categorical NB, Bernoulli NB, ...
