Classification by pairwise coupling

WebCLASSIFICATION BY PAIRWISE COUPLING ByTrevorHastie1 andRobertTibshirani2 Stanford University and University of Toronto We discuss a strategy for polychotomous classification that involves estimating class probabilities for each pair of classes, and then coupling the estimates together. The coupling model is similar to the Bradley–Terry WebOct 9, 2002 · In this paper, a novel algorithm is proposed to tackle multi-class classification problems. For a K-class classification task, an array of K optimal pairwise coupling classifiers (O-PWC) is constructed, each of which is optimal to the corresponding class and provides a reliable probability estimation for that class. The classification accuracy rate is …
