Approximation of high-dimensional mappings by neural networsk is investigated in the context of nonlinear approximation theory.It is shown that the "curse of dimensionality" can be avoided when functions to be approximated have small special norms, which are tailored to the type of computational units. Properties of such norms and method of derivation of their estimates are described. Estimates of rates of nonlinear approximation are applied to neural network learning formalized as approximate minimization.
