Abstract
In data mining and in classification specifically, cost issues have been undervalued
for a long time, although they are of crucial importance in real-world applications.
Recently, however, cost issues have received growing attention, see for example
[1,2,3]. Cost-sensitive classifiers are usually based on the assumption of constant
misclassification costs between given classes, that is, the cost incurred when an
object of class j is erroneously classified as belonging to class /. In many domains,
the same type of error may have differing costs due to particular characteristics
