Pytorch layernorm vs batchnorm

WebBatchNorm和LayerNorm两者都是将张量的数据进行标准化的函数，区别在于BatchNorm是把一个batch里的所有样本作为元素做标准化，类似于我们统计学中讲的“组间”。layerNorm是把一个样本中所有数据作为元素做标准化，类似于统计学中的“组内”。下面直接举例说明。 WebA torch.nn.BatchNorm2d module with lazy initialization of the num_features argument of the BatchNorm2d that is inferred from the input.size (1) . The attributes that will be lazily initialized are weight, bias , running_mean and running_var.

WebBN is better understood as a technique which reduces second-order relationships between parameters of different layers than a method to reduce covariate shift. Thus, the before/after distinction doesn't matter, and differences in performance could simply be because of other particular artefacts of the model.
