public class RT
extends ProblemTransformationMethod

RT.java - The 'Ranking + Threshold' classifier. Duplicates each multi-labelled example, and assigns one of the labels (only) to each copy; then trains a regular multi-class base classifier. At test time, a threshold separates relevant from irrelevant labels using the posterior for each class value (i.e., label).
