Fig. 2.

Two-dimensional pruned convex hulls determined by normalized expression values of two representative genes for 56 colon training samples classified as cancerous or noncancerous. Training points are represented by filled symbols while test points are represented by unfilled symbols. The test points are labeled 1–6 and are superimposed for illustration purposes only; they are not used to train the algorithm. This ensemble member votes correctly on test points 1, 2, 5 and 6, but does not vote on test points 3 and 4. See Kodell et al. [9] for the original figure and a full explanation.
