5. Fuzzy GMDH with different partial descriptions: orthogonal polynomials

As it is well known from the general GMDH theory, model pretenders are generated on the base of so-called partial description—elementary models of two variables. Usually as partial descriptions, linear or quadratic polynomials are used. The alternative to this class of models is application of orthogonal polynomials. The choice of orthogonal polynomials as partial descriptions is determined by the following advantages:
