The principle here is MECE.　FX宣布续订《姿态》第三季。毕竟他们现在是越王您的臣民，他们的基业也都在越国。OvO pairs the N classes in pairs to generate N (N-1)/2 binary classification tasks. For example, OvO will train a classifier to distinguish classes Ci and Cj. The classifier takes the Ci class sample in D as a positive example and the Cj class sample as a counterexample. In the testing phase, the new samples will be submitted to all classifiers at the same time, so we will get N (N-1)/2 classification results, and the final results can be generated by voting: that is, the category that is predicted most is taken as the final classification result. Figure 3.4 shows a schematic diagram.Leader
