Abstract: In this paper, we introduce a heuristic method for gene selection. We target this method, coupled with RadViz visualisation, to the visual prediction of tissue samples which may exist in normal and disease states. As a result of this coupling, the gene selection process, predictive model training and evaluation as well as the model's application for tissue sample prediction can all be intuitively visualised. Such integrated visual analytics enhance the insight provided by classical statistics and machine learning methods. The case study shows our proposed method is cost effective and achieves competitive performance when compared with several widely used techniques.
