II. General Methods for Determining Minimum Wage Standards胡钧和汪魁听了精神一振，急忙上前听令。呼——王陆轻轻呼出一口气。It is easy to see that OvR only needs to train N classifiers, while OvO needs to train N (N-1)/2 classifiers, so the storage overhead and test time overhead of OvO are usually larger than OvR. However, in training, each classifier of OVR uses all training samples, while each classifier of OVO only uses samples of two classes. Therefore, when there are many classes, the training time cost of OVO is usually smaller than that of OVR. As for the prediction performance, it depends on the specific data distribution, which is similar in most cases.The matter of. The teacher is also looking forward to starting the work earlier.The fifth step is to write the implementation of each state class. It is worth noting that StateFactory is used to avoid the problems caused by the absence of abstract classes in javascript.
