Исследуется качество данного метода на различных модельных задачах бинарной классификации. Полученные результаты анализируются и даются рекомендации по применению указанного метода.</p></abstract><trans-abstract xml:lang="en"><p>Gradient boosting method with random rotations is considered, where before training each base learner random rotation is applied to the feature space. The accuracy metric of the given method is estimated for a broad range of generated problems of binary classification.
