Part of the Advances in Intelligent and Soft Computing book series (AINSC, volume 102)

Summary

In the paper the problem of cost in the two-stage binary classifier is presented. Assuming that both the tree structure and the feature used at each non-terminal node have been specified, we present the expected total cost for two cases. The first one concerns the zero-one loss function, the second concerns the stage-dependent loss function. The work focuses on the difference between the expected total costs for these two cases of loss function. Obtained results relate to the globally optimal strategy of Bayes multistage classifier.
