Sammon's mapping is conventionally used for exploratory data projection, and as such is usually inapplicable for classification. In this paper we apply a neural network (NN) implementation of Sammon's mapping to classification by extracting an arbitrary number of projections. The projection map and classification accuracy of the mapping are compared with those of the auto-associative NN (AANN), multilayer perceptron (MLP) and principal component (PC) feature extractor for chromosome data. We
more » ... onstrate that chromosome classification based on Sammon's (unsupervised) mapping is superior to classification based on the AANN and PC feature extractor and highly comparable with that based on the (supervised) MLP.
