Naive Bayes

A fast, simple classifier based on probabilities, often used for text and spam filtering.

Definition

Naive Bayes is a fast, simple classification method based on probability. It assumes each input feature contributes independently to the result — a 'naive' simplification that rarely holds exactly but works surprisingly well in practice. It is a classic choice for text tasks like spam filtering and topic labeling.
