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.

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.< h2 > This is a heading Charming points are gifts given to you by others.啊？陈启嘴巴微张，都不知道该说什么好了。见到天启时，他会风轻云淡地说道：天启，幸会了，我就是那个写了十亿字的男人。自盘古开天以来，童氏一族即拥有天赋异能，一向为朝廷所倚重。直至秦末，叛徒尹仲因心术不正被族人放逐，忿而煽动皇帝欲将童氏灭族，幸赖大将军龙腾舍命相救，令童氏一族避入深山。族长感慨浮生若梦，繁华过处不过是一场镜花水月，因而将避居处命名为「水月洞天」，并严令童氏一族，永世不得出山！MDT members should learn from each other and share their successful experiences in communication.
