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.

On one occasion, in class, Lin Nian was always making jokes and fidgeting. The teacher said, "Next to him, check if Lin Nian has diapers because the little BB without diapers is making shocks all day." Lin Nian said angrily, "You just wrap diapers! You are the little BB!"From the training of professional weightlifters, the belt is usually used only when the leg strength is heavy and the squat is deep. Most players who use belts in professional matches wear them only when they have injuries. If you don't know this, you can naturally count the results. But this "possible explanation" is too superficial. In this way, can I say that wearing knee pads will cause knee injuries in NBA matches? Or do you think frequent visits to dental hospitals will lead to unhealthy teeth?
