In this paper, we present a review of some recent works on approximation by feedforward neural networks. A particular emphasis is placed on the computational aspects of the problem, i.e. we discuss the possibility of realizing a feedforward neural network which achieves a prescribed degree of accura

β¦ Synopsis
We show that standardfeedforward networks with asl ew as a single hidden layer can uniformly approximate continuousfunctions on compacta provided that the activation function if; is locally R iemann integrable and nonpolynomial, and have universal LP(Jl) approximation capabilities for finite and compactly supportedinput environment measures JL provided that if; is locall y boundedand nonpolyn om ial. In both cases, the input-to-hidden weights and hidden layer biases can be constrained to arbitraril y small sets; if in addition if; is locally analytic a single universalbias will do.

For the nearly exponential type of feedforward neural networks (neFNNs), the essential order of their approximation is revealed. It is proven that for any continuous function defined on a compact set of R(d), there exist three layers of neFNNs with the fixed number of hidden neurons that attain the
