Generalized Boosting Algorithms for Convex Optimization
Generalized Boosting Algorithms Convex Optimization
2011/6/21
Boosting is a popular way to derive power-
ful learners from simpler hypothesis classes.
Following previous work (Mason et al., 1999;
Friedman, 2000) on general boosting frame-
works, we analyze g...

Fisher-consistent loss functions play a fundamental role in the
construction of successful binary margin-based classifiers. In this paper
we establish the Fisher-consistency condition for multicateg...
