In this paper, we discuss the role of clustering techniques in the des
ign of neural networks. Specifically, we address the issue in relation
to two network paradigms: one based on back-propagation and the other
based on radial basis functions. In the former case, we demonstrate,
emprically, that by employing clustering techniques, the training effo
rt may be drastically brought down. In the latter case, we demonstrate
that clustering techniques can be employed to build more robust class
ifiers. We also discuss the role of clustering in the design of hierar
chical systems. Specifically, we discuss a hierarchical system based o
n radial basis functions.
