Abslracl--Let f be an arbitrary continuous function defined on R d and h be any sigmoid function. Then, there is a linear combination of scaled shifted rotations of h, which approximates f uniformly on the whole space R d, if a certain such linear combination approximates f uniformly in a neighbourh
