Learning from data formalized as a minimization of a relularized empirical error is studied in terms of approximate minimization over sets of functions computable by networks with increasing number of hidden units. There are derived upper bounds on speed of convergence of infima achievable over networks with n hidden inits to the global infimum. The bounds are expressed in terms of norms tailored to the type of network units and moduli of continuity of regularized empirical error functionals.
