Classification by pairwise coupling
WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): 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 method for paired comparisons. We study the nature of the …

WebMay 1, 2024 · In SBELM, Bernoulli distribution is employed for binary classification, and then extended to multi-class classification using pairwise coupling. However, pairwise coupling suffers from three significant drawbacks for multi-class classification: 1) classification ambiguity and uncovered class regions; 2) large model size; 3) insufficient ... http://www.flexiblecouplingchina.com/coupling-types-and-classification/
WebAs a way of such decomposition, we propose a novel pairwise coupling method based on the TrueSkill ranking system. Instead of aggregating all pairwise binary classification results for the final decision, the proposed method keeps track of the ranks of the classes during the successive binary classification procedure. Especially, selection of a ...
