A new approach for exploring multivariate data: self-organising maps.(data management, self-organising map )

From: International Journal of Market Research | Date: June 22, 2004| Author: | Copyright information
    This paper introduces a form of neural network known as the 
    self-organising map (SOM), which has been used extensively outside 
    of marketing. The SOM clusters data in a manner similar to cluster 
    analysis, but has the additional benefit of ordering the clusters, 
    enabling the visualisation of large numbers of clusters. The 
    technique is particularly well suited to the analysis of large 
    datasets.
