Hierarchical classification compared to one-vs-all classifier On one problem of multiclassification in socio-economic modeling and application of hierarchical classifiers

In this paper, we describe an approach to the multiclassification problem under the conditions of a substantial class imbalance, which, as a rule, arises in problems of socio-economic subject areas, using the example of a specific machine learning classification problem. One of the possible methods of dealing with unbalanced classes is considered: the construction of hierarchical classifiers and the calculation of the effectiveness of a multilevel classifier.
