Neural networks for localized approximation
We prove that feedforward artificial neural networks with a single hidden layer and an ideal sigmoidal response function cannot provide localized approximation in a Euclidean space of dimension
A constructive method for multivariate function approximation by multilayer perceptrons
TLDR
It is shown how to construct a perceptron with two hidden layers for multivariate function approximation, which can perform function approximation in the same manner as networks based on Gaussian potential functions, by linear combination of local functions.
Constructive Approximation of Discontinuous Functions by Neural Networks
TLDR
A constructive proof that a real, piecewise continuous function can be almost uniformly approximated by single hidden-layer feedforward neural networks (SLFNNs) is given.

TLDR
It is shown that a simple geometric proof of this theorem can be extended to networks of units using a smooth output function, and a recent result on the approximation of polynomials by fixed size networks is improved.
Generalization and Approximation Capabilities of Multilayer Networks
TLDR
The theory allows one to specify a finite discrete set of training data and a network structure that generalizes and approximates any given continuous mapping between sets of contours on a plane within any given permissible error.
NEURAL NETWORKS FOR OPTIMAL APPROXIMATION OF SMOOTH
We prove that neural networks with a single hidden layer are capable of providing an optimal order of approximation for functions assumed to possess a given number of derivatives, if the activation

Universal approximation using feedforward networks with non-sigmoid hidden layer activation functions
TLDR
Multilayer feedforward networks possess universal approximation capabilities by virtue of the presence of intermediate layers with sufficiently many parallel processors; the properties of the intermediate-layer activation function are not so crucial.

TLDR
It is shown that there are many powerful techniques for reducing the number of spurious terms, and that the high order approach has many advantages over a cascaded slab approach in certain problem areas.
