Neural networks are widely used to approximating continuous functions. In order to study its approximation ability, we discuss the constructive approximation on the whole real lines by an radial basis function (RBF) neural network with a fixed weight. Using the convolution method, we present a family of RBF neural networks with fixed weights that are able to uniformly approximate continuous functions on a compact interval. Our method of proof is constructive. And this work provides a method for function approximation.
