The noise range is modeled through four magnitudes characterizing ultimate jitters and shifts in wear influencing factors. Accuracy and vari-ance gains of equally - weighted compositions seem to be increasing when noise intensities become lower. When boosting ensembles are composed from ordinary classifiers, high-accurate tracking fails. Only composing ensembles from a lot of the best optimized perceptrons, the accuracy improves by 1,5 % for the averaged tracking error rate and by 7,7 % for the tracking error rate at noise maximum. Here, the boosting appears to have its limit. But ensembles of equally-weighted compositions of perceptrons perform even better than ensembles of perceptrons weighted after training. And for ensuring high-accurate dis-continuous tracking of wear states, we just need perceptrons trained by quite different backpropagation methods}, number={2}, journal={Problems of Tribology}, author={Romanuke, V.V.}, year={2015}, month={Jun.}, pages={53–56} }
