“…It is fundamentally important to consider the criteria of quality of the obtained classification tree models, which depend on the model error, the power of the initial data array of the TS, the size of the test set (the number of training pairs and the dimension of the attribute space of the problem), the number of model parameters, etcetera [15,27].…”

“…In contrast to the existing methods, the main feature of tree-like recognition systems is that the importance of individual features (groups of features or algorithms) is determined in reference to the function that specifies the partition of objects into classes [23]. Thus, work [15] is devoted to the principal issues concerning the generation of decision trees in the case of uninformative features, estimating the quality of the constructed models. The ability of classification tree structures to perform one-dimensional branching (the selection of features, attributes) for analyzing the impact (importance, quality) of individual variables (vertices) makes it possible to work with variables of different types in the form of predicates, generalized features, in the case of ACTs -with the respective autonomous classification and recognition algorithms.…”

“…Moreover, the disadvantage of the functionality of assessing the quality of attributes in the cited papers is the existence of restrictions in terms of generating the LCT structure. Thus, study [23] considers fundamental issues related to the generation of decision trees for the case of low-informative attributes. A potential to improve the cited study could be the use of combinations and sets of attributes in order to generate informative vertices of LCT structures.…”
