Learning decision trees for loss minimization in multi-class problems

Oregon State University. Dept. of Computer Science; Margineantu, Dragos D. (Dragos Dorin); Dietterich, Thomas G. (Corvallis, OR : Oregon State University, Dept. of Computer Science, 1999)

Many machine learning applications require classifiers that minimize an asymmetric loss function rather than the raw misclassification rate. We study methods for modifying C4.5 to incorporate arbitrary loss matrices. On ...
