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.

After executing the command to add rules, look at the INPUT chain again and find that the rules have been successfully "appended" to the end of the INPUT chain. Now, the first rule indicates to discard all messages from 192.168. 1.146 and the second rule indicates to accept all messages from 192.168. 1.146. What is the result? Practice shows true knowledge.
