Paper Abstract

A variety of artificial neural networks are evaluated for their classification abilities under noisy inputs. These networks include feedforward networks, localized basis function networks, and exemplar classifiers. The performance of radial basis function classifiers deteriorate rapidly in the presence of noise, but elliptical basis variants are able to adapt to extraneous input components quite robustly. For feedforward networks, selective pruning of weights based on an `optimal brain damage' approach helps in noise-tolerant classification. Results from a radar classification problem are presented.
