The multinomial distribution normally requires integer feature counts. However, in practice, fractional counts such as tf-idf may also work. ... 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.
