In this regard, the traditional kernel algorithm faces difficulties stemming from the dimensionality associated with the memory length of the dynamic block. A particular class of input sequences has been proposed, which aids in reducing dimensionality and consequently improves the convergence rate of the estimator to the true characteristics. A theoretical analysis of the suggested method is presented.}, type={Article}, title={Dimensionality reduction in kernel-based identification of Wiener system by cyclostationary excitations}, URL={http://ochroma.man.poznan.pl/Content/135231/4_4985_L_Maik_sk_new.pdf}, doi={10.24425/ijet.2025.153581}, keywords={Nonlinear systems, Identification, Kernel estimation, Wiener structure, Curse of dimensionality, Cyclostationary signals, Nonparametric regression}, }
