Abstract
This paper describes the application of a genetic algorithm to the optimisation of a data projection method known as projection pursuit. Exploratory projection pursuit, named by Friedman and Tukey (1974) is a statistical method for viewing low (typically one or two) dimensional projections of higher dimensional data. This has been applied in data analysis as a visualisation technique for examination of possible nonlinear structure perhaps not reveewaled by other techniques such as Principal Component Analysis (Huber, 1985; Jones and Sibson, 1987). It is claimed that bec ause it works in low dimensional space, it can overcome the problem known as the 'curse of dimensionality' (Bellman 1961) which plagues other multivariate techniques. This is usually caused by having a high dimensional data set which contains too few observations to adequately represent the data space, a problem frequently found in real, industrial problems.
