15. The article of claim 10 further storing instructions that, if executed, enable the processor-based system to determine a nearest neighbor based supervised classifier.
10. An article comprising a medium storing instructions that, if executed, enable a processor-based system to: develop a tree based supervised classifier; determine whether the two data points would take the same or different branch at each branch point in a pass through a tree taken by both points; accrue one point each time the same branch is taken; determine the total number of points divided by the total number of branch points visited; determine a non-binary affinity measure between data points using said supervised classifier; and provide a visualization of the relationships between data points using said non-binary affinity measure.
