        This article discusses the basic concepts and methods used in solving the classification problem in machine learning. The definition of classification as the process of assigning objects to predefined classes based on the analysis of object features is given. Exam-ples of binary and multi-class classification are given. On the example of constructing the sim-plest signal classifier using a decision tree, the process of creating a classifier and analyzing its effectiveness based on test data using a confusion matrix and quality indicators such as accura-cy, completeness, F-measure is examined in detail. Formulas for calculating these indicators are given. The importance of representativeness of test data for assessing the quality of the classifier is noted. In conclusion, the author concludes that the accuracy on the test set Te is determined as access only to the true classes of a small part of the instance space, therefore, the estimate is everything we can hope for. Therefore, it is important that the test set be as repre-sentative as possible. This is usually formalized by the assumption that the appearance of in-stances in the world is governed by an unknown probability distribution on X, and that the test set Te is generated according to this distribution. In general, the article is of interest to special-ists in the field of machine learning and data analysis.<\/em><\/p>\n
