Abstract

In all pattern recognition technologies, a crucial question is what features to extract and use for the basis of a recognition system. There are well-established techniques for ranking features to be used in linear combination, but when non-linear combination technologies, such as neural networks, are contemplated feature significance ranking is more problematic. In this paper we present a practical technique for ranking features in terms of significance for a neural-net pattern recognizer. We provide the results of applying this clamping technique to a small selection of problems, both well-defined abstract problems that permit a precise exploration of the technology, and more realistic data-defined problems that demonstrate its practical worth.
