Abstract

The visualization of continuous multi-dimensional data based on their projection in a 2-dimensional space is a way to detect visually interesting patterns, as far as the projection provides a faithful image of the original data. We propose to visualize directly in the projection space, how much the neighborhood has been preserved or not during the projection. We color the Vorono'i cells associated with the segments of the Delaunay graph of the projections, according to their stretching or compression. We experiment these techniques with the Principal Component Analysis and the Curvilinear Component Analysis applied to different databases.
