Constraint Classification: A New Approach to Multiclass Classification and Ranking
Sariel Har-Peled, Dan Roth, Dav Zimak · 2002
We introduce constraint classification, a framework capturing many flavors of multiclass classification including multilabel classification and ranking, and present a meta-algorithm for learning in this framework. We provide generalization bounds when using a collection of k linear functions to represent each hypothesis. We also present empirical and theoretical evidence that constraint classification is more powerful than existing methods of multiclass classification. 1
