Configuring RBF neural networks

open access: yesElectronics Letters, 1998
A novel method (based on the characteristics of scatter matrices and frequency-sensitive competitive learning) for training the hidden layer of a radial basis function neural network is proposed. The method is demonstrated to be robust and to outperform the state-of-the-art algorithm.

A Novel Adaptive Kernel for the RBF Neural Networks [PDF]

open access: yesCircuits, Systems, and Signal Processing, 2016
In this paper, we propose a novel adaptive kernel for the radial basis function (RBF) neural networks. The proposed kernel adaptively fuses the Euclidean and cosine distance measures to exploit the reciprocating properties of the two. The proposed framework dynamically adapts the weights of the participating kernels using the gradient descent method ...

A Novel Kernel for RBF Based Neural Networks [PDF]

open access: yesAbstract and Applied Analysis, 2014
Radial basis function (RBF) is well known to provide excellent performance in function approximation and pattern classification. The conventional RBF uses basis functions which rely on distance measures such as Gaussian kernel of Euclidean distance (ED) between feature vector and neuron’s center, and so forth.
