Given the success of neural networks in a variety of applications in e
ngineering, such as speech and image quantization, it is natural to co
nsider its application to similar problems in other domains. A related
problem that arises in business is market segmentation for which clus
tering techniques are used. In this paper, we explore the ability of a
specific neural network, namely the Frequency-Sensitive Competitive L
earning Algorithm (FSCL), to cluster data for developing strategic mar
keting decisions. To this end, we investigate the comparative performa
nce of FSCL vis-a-vis the K-means clustering technique. A cluster anal
ysis conducted on brand choice data for the coffee category revealed t
hat the two methodologies resulted in widely differing cluster solutio
ns. In an effort to address the dispute over the appropriate methodolo
gy, a comparative performance investigation was undertaken using simul
ated data with known cluster solutions in a fairly large experimental
design to mimic varying data quality to reflect data collection and me
asurement error. Based on the results of these studies, it is observed
that a combination of the two methodologies, wherein the results of t
he FSCL network are input as seeds to the K-means, seems to provide mo
re managerially insightful segmentation schemes.
