Methods for Black-Box Diagnostics Using Volterra Kernels. Vitalij Pavlenko, Aleksandr Fomin

Abstract. The method of a black-box diagnostics, founded on nonparametric identification of objects using integro- power Volterra series is offered. It provides a set of diagnostic features formed on base of multidimensional Volterra kernels: discrete values of Volterra kernels, heuristic features, moments and wavelet transform coefficients. It is researched a self-descriptiveness of provided features using classifier on base of back propagation neural nets. The diagnostic spaces are formed by method of all features combination selection.

Keywords. Black-box diagnostics, nonparametric identification, Volterra series, Volterra kernels, self-descriptiveness.
