Abstract :
The analysis and interpretation of high-dimensional biomedical datasets for the purposes of confirmatory or exploratory data analysis is a challenging problem. The process raises issues that are not only typically associated with high-dimensional data but also with software implementations of the visualization models. The relative distance plane projection method, which uses a distance-based mapping for visualizing high dimensional patterns and their relative relationships, addresses these confounding factors. This paper describes the algorithm, its implementation in software, and the specialized user interface. Its functionality is demonstrated using a high-dimensional biomedical dataset.
