Abstract

Humans have an exceptional capacity to identify patterns, clusters and a variety of characteristics in 1- and 2- dimensional spaces. In recent years immersive techniques and virtual reality have provided a third dimension. However, we a re usually intimidated if we go up to four dimensions and we cannot identify but the simpler patterns in 5 or 6-dimensional spaces. Fuzzy data contributes to further complication and each pixel is not only associated with several spectral values but with several class membership values as well. Projection pursuit is statistical method that seeks interesting projections of a high dimensional space into a lower one according to a measure of interestingness.
