Abstract :The subject of research in the article is the stage of preliminary data processing for machine learning algorithms and consideration of various pre-processing techniques and evaluation the informativeness of features-based parameters network infrastructure monitoring for effective intellectual state analysis. The aim of the work - to consider various data preprocessing techniques and evaluation of informativeness for determining controls parameters of network infrastructure for more efficient intellectual analysis. The article solves following tasks: consideration of methods for selecting parameters; parameter determination for assessing the state of a network filtration methods, based on algorithms that are not related to classification methods; wrapper methods, based on importance features information, obtained from classification or regression methods, which can determine data deeper patterns; embedded methods that perform feature selection during the classifier training procedure and optimize the set of features used to improve accuracy. Results: various preliminary processing techniques and evaluation of informativeness of feature were analyzed to determine the parameters of network infrastructure monitoring. The results of feature selection methods were analyzed to simplify the different machine learning models. The minimum parameters set has been formed for monitoring the state of the network infrastructure. Conclusions: The use of feature selection methods made it possible to reduce the input parameter set for classifying the state of the network infrastructure methods.
