Realisable Classifiers: Improving Operating Performance on Variable Cost Problems
M. J. J. Scott, Mahesan Niranjan, Richard W. Prager · 1998
A novel method is described for obtaining superior classification performance over a variable range of classification costs. By analysis of a set of existing classifiers using a receiver operating characteristic (###)curve,a set of new realisable classifiers may be obtained by a random combination of two of the existing classifiers. These classifiers lie on the convex hull that contains the original ### points for the existing classifiers. This hull is the maximum realisable ### (#####).
