WebNaïve Bayesian classification is a supervised learning technique and a statistical classification method. Bayes theorem is used in decision-making and uses the knowledge of prior events to predict future events. (1.5) WebMay 7, 2024 · Naive Bayes is a classification algorithm that is suitable for binary and multiclass classification. It is a supervised classification technique used to classify future objects by assigning class labels to instances/records using conditional probability. In supervised classification, training data is already labeled with a class.
