An important consideration in designing an RBF network is the choice of the number of hidden units required for the network to generalize optimally. A new method, which is called canonical subspace analysis, is proposed for the selection of the number of hidden units. The numerical results show that with the number of the hidden units determined using the proposed method, minimum prediction errors are obtained.
