The purpose of the publication is to analyse popular classification algorithms in machine
learning. The following classifiers were studied: Naive Bayes Classifier, Decision Tree and AdaBoost
Ensemble Algorithm. Their advantages and disadvantages are discussed. Research shows that there is
no comprehensive universal method or algorithm for classification in machine learning. Each method
or algorithm works well depending on the specifics of the task and the data used.

Key words

Classification, Machine learning, Naive Bayes classifier, Decision tree, Ada Boost Ensemble
