I worked on extending the work of Dr. Marjan Trutschl’s SmartJitter technique for intelligently resolving point occlusion to include other types of plots including 3D scatter plots and radviz plots. The basic idea is to eliminate overplotting of points who have the same values in the dimensions for which the plot was created (x and y for example), but still provide meaningful spatial relationship between the points through the use of a SOM.
This work was accepted to the IEEE IVBI ‘07 Conference in Zurich, Switzerland in a paper titled “2D and 3D Neural-Network Based Visualization of High-Dimensional Biomedical Data” (Link)
