Investigation of selective properties of the error bias criterion. Liudmyla Somina,Ievgeniia Savchenko, Volodymyr Stepashko

Abstract. Selective properties of a new error bias criterion are investigated first analytically. It is shown that the same optimal model can be chosen by the new criterion as by classical solution bias criterion. This criterion is more sensitive to change of model complexity then classical. The numerical analysis of the error bias criterion for different levels of noise in data is carried out. The example shows that error bias criterion has the main property of effective external criterion: property of noise-immunity. It is shown that sequential using of the regularity criterion firstly and the error bias criterion secondly are the most reasonable for selection of an optimal complexity model.

Keywords. Inductive modelling, GMDH, regularity criterion, noise-immunity, error bias criterion, Pareto region.
