@article{Ivakhnenko1971PolynomialTO, title={Polynomial Theory of Complex Systems}, author={A. G. Ivakhnenko}, journal={IEEE Trans. Syst. Man Cybern.}, year={1971}, volume={1}, pages={364-378} }

A complex multidimensional decision hypersurface can be approximated by a set of polynomials in the input signals (properties) which contain information about the hypersurface of interest. The hypersurface is usually described by a number of experimental (vector) points and simple functions of their coordinates. The approach taken in this paper to approximating the decision hypersurface, and hence the input-output relationship of a complex system, is to fit a high-degree multinomial to the…
