This work is a logical extension of the works of Shurygin over the period from 1994 to 1996 and is devoted to the development of approaches to the stable estimation of the parameters of regression models. The results obtained earlier are extended to the cases of a nonlinear regression and a feedforward neural network with one hidden layer. Theoretical results are confirmed by numerical experiments. The problem of numerical modeling consisted in the construction of a system for the prediction of a change in the Gibbs free energy (Δ G) in the course of the formation of protein-protein and protein-ligand complexes. For the training set, data on 150 complexes of a various nature are used, for which there exists an experimental estimate (Δ G). For independent variables, different rated values of the physicochemical parameters of data for complexes are used.
