广船是尖头，有一根首柱像鼻子一样翘起来。是啊。[Time of Publication] October 15, 2016　　与此同时，草原上迎来了几名罕见的来客：孤独的北极熊、聒噪的高卢鸡、相伴上百年沧桑岁月的乌龟夫妇、活泼的袋鼠以及爱放臭屁的笑笑。他们都是因为人类的颟顸与无知，而被迫离开赖以栖息的家园，只为寻找一个没有人类足迹的乐土。只是非洲草原的情况也不容乐观，来自异乡的动物们不得不和当地的动物朋友联合起来，踏上寻找水源的惊险之旅……The column of implementing mediators is as follows:　由于童年的悲惨遭遇，直枝理树（堀江由衣 配音）的个性变得十分孤僻。长着一张娃娃脸，沉默寡言，没有朋友，这样的理树成为了大家眼里的怪胎。某一日，性格傲娇爱猫如命的枣铃（民安智惠 配音），正直开朗稳重可靠的枣恭介（绿川光 配音），四肢发达头脑简单的井之原真人（神奈延年 配音），成熟勇敢剑术一流的宫泽谦吾（织田优成 配音）四人出现在了绝望的理树面前。他们自称“Little Busters”，想要利用理树的力量来完成拯救世界的重任。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.
