Analysis of the Dependence of the Performance of the Ensemble on the Accuracy of its Individual Models

The article devoted to studying the problem of finding methods to increase modeling efficiency by combining the results of calculations of several models. Conditions of expediency of creation of ensemble of models for the solution of the problem of binary classification are investigated. The theoretical basis for the dependence of the ensemble efficiency on the accuracy of the models that form it is studied. Suggestions are given for creating an ensemble of models and increasing its effectiveness. Keywords—ensemble (committee) of models, probability of a correct classification, surface of probabilities
