Bounds on Rates of Variable-Basis and Neural Network Approximation.
Tightness of bounds on rates of approximation by feedforward neural networks is investigated in a more general context of nonlinear approximation by variable-basis functions. Tight bounds on the worst case error in appr...

Bounds on Rates af Approximation by Neural Networks in Lp-spaces.
We derive upper bounds on rates of convergence of neural network approximation in Lp-spaces. Our bound are based on a version of Maurey-Jones-Barron Theorem for Lp-spaces. They are established in terms of L1-norm of a weight functio...

Tight Bounds on Rates of Neural-Network Approximation.
Complexity of neural networks measured by the number of hidden units is studied in terms of rates of approximation. Limitations of improvements of upper bounds of the order of O(n exp(-1/2)) on such rates are investigated f...

A Sobolev-Type Upper Bound for Rates of Approximation by Linear Combinations of Heaviside Plane Waves
For sufficiently differntiable functions, there are derived estimates of rates of approximation by linear combinations of Heaviside plane waves converging to zero exponentially fast. The estimates depend on Sobolev seminorms and the...
