Figure 1.

SVM classification on a three-dimensional subspace. Shown are points, at which cells would be classified as being leukemic by the learned SVM, in a three-dimensional subspace of the six-dimensional space spanned by all variables. The three variables not shown are fixed at their median value. The color of the points is meant to emphasize the three-dimensionality of the plot, with brighter points being closer to a hypothetical observer in front of the plot.
