Annotation:

The paper is a continuation of the research dedicated to the applicability of machine learning methods for solving the problem of identifying and filtering gross errors in measurements of parameters characterizing the operational modes of pipeline systems (PS). In the previous part of the research an original method for detecting gross measurement errors was proposed. The method is based on the regression reconstruction with help of machine learning models. Stochastic gradient boosting of decision-making trees model was used for solving regression tasks. The paper provides a comparative analysis of the models applicable for the regression estimation of the pipeline modes measurements. Possible alternatives are considered as a key step in the method for solving the problem of detecting gross errors when measuring real pipelines mode parameters.
