| Аннотація | Context. The task of automation of feature informativeness estimation process in diagnostics and pattern recognition problems is solved. The object of the research is the process of informative feature selection. The subject of the research are the criteria of feature informativeness estimation.
Objective. The research objective is to develop the system of criteria for feature informativeness estimation which enables to compute informativeness of interdependent feature sets.
Method. The system of criteria for feature informativeness estimation is proposed. The proposed system is based on the idea that feature significance is computed according to spatial location of observations of different classes (size of changing of output parameter). The developed criteria system enables to estimate individual and group feature informativeness in classification and regression problems in situations when initial data samples contain redundant and interdependent features as well as observations with missing value |
