BN、LN、IN、GN的区别 一、Batch Normalization 卷积神经网络的出现,网络参数量大大减低,使得几十层的深层网络成为可能。然而,在残差网络出现之前,网络的加深使得网络训练变得非常不稳定,甚至出现网络长时间不更新甚至不收敛的现象,同时网络对超参数比较敏感,超参数的微量扰动也会导致网络的训练轨迹完全改变。 &nbs......
Normalization is the process of reducing or completely eliminating the occurrence of redundant data in the database. Normalization refers to the process of designing relational database tables from the ER model. It is a part of the logical design process and is a requirement for online transact...
