Abstract

The performance of a classifier depends on the accuracy of measurement of the feature values. In this paper, we describe an approach for estimating feature values using a clustering technique. To begin with, we discuss the role of multiple versions of a pattern in pattern analysis. Specifically, we describe how clustering can be employed in pattern analysis. We follow this with a discussion on the usefulness of clustering in class-characterization. Specifically, we describe an approach to account for feature value measurement errors. The proposed approach has been applied in the context of speech recognition. Specifically, we inves- tigate the estimation of formant frequencies (feature values) that form an essential ingredient in the design of a speaker-inde- pendent digit recognition system (classifier).
