Abstract
Mapping scheme consists in projecting data samples represented as points in high-dimensional data space onto a subspace of few dimensions, generally two dimensions. Mapping methods are used in order to eliminate statistical redundancies in the original data set and to facilitate the visual inspection of the data by the analyst which discover clusters between the data samples. A feedforward neural network trained by means of an unsupervised backpropagation algorithm is used for the nonlinear mapping. The Sammon’s stress is used as an error function for the learning algorithm. The number of hidden units is related to the complexity of the nonlinear functions that can be generated by the network and is selected by means of an informational criterion. To provide some insight into the behavior of the interactive system, and to presents its main facilities, some results are reported.
