Our goal is to code a spam filter from scratch that classifies messages with an accuracy greater than 80%. To build our spam filter, we'll use a dataset of 5,572 SMS messages. Tiago A. Almeida and José María Gómez Hidalgo put ...
WebNaive Bayes is a supervised machine learning algorithm used for classification. It uses the Bayes theorem of probability to calculate the probability of an event occurring. It assumes that the features of the data are independent of each other, which makes the algorithm faster and more efficient.
