- Group norms are the expectations and behaviors associated with a social group, such as a nationality, an organization, or a sports team. Group norms can emerge during group interaction as group members are exposed to the opinions, or observe the actions, of fellow group members.

一句话概括，Group Normbalization（GN）是一种新的深度学习归一化方式，可以替代BN。 众所周知，BN是深度学习中常使用的归一化方法，在提升训练以及收敛速度上发挥了重大的作用，是深度学习上里程碑式的工作，但是其仍然存在一些问题，而新提出的GN解决了BN式归一化对batch size依赖的影响。 详细的BN介绍可以参考我的另一篇博客. So, BN到底出了什么问题， GN又厉害在哪里？ What's wrong with BN.
e. In abstract algebra, a normal subgroup (also known as an invariant subgroup or self-conjugate subgroup) [1] is a subgroup that is invariant under conjugation by members of the group of which it is a part. In other words, a subgroup of the group is normal in if and only if for all and .
Norms are the recognized rules of behavior for group members. Norms influence the ways we communicate with other members, and ultimately, the outcome of group participation. Norms are important because, as we highlighted in the “norming” stage of group development, they are the defining characteristics of groups.

Group Normalization (GN)是由2018年3月份何恺明团队提出，GN优化了BN在比较小的mini-batch情况下表现不太好的劣势。 Group Normalization (GN) 则是提出的一种 BN 的替代方法，其是首先将 Channels 划分为多个 groups，再计算每个 group 内的均值和方法，以进行归一化。 GB的计算与Batch Size无关，因此对于高精度图片小BatchSize的情况也是非常稳定的， 下图是比较BN和GN在Batch Size越来越小的变化中，模型错误率变化的对比图： 因此在实验的时候，可以在尝试使用GN来代替BN哦~ 其实不难发现，GN和LN是存在一定的关系的。 上图中有四种Normalization的方法。

Group norms are rules or guidelines that reflect expectations of how group members should act and interact. They define what behaviors are acceptable or not; good or not; right or not; or appropriate or not (O’Hair & Wieman, p. 19).
