What are the consequences of layer norm vs batch norm?

WebConvModule. A conv block that bundles conv/norm/activation layers. This block simplifies the usage of convolution layers, which are commonly used with a norm layer (e.g., BatchNorm) and activation layer (e.g., ReLU). It is based upon three build methods: build_conv_layer () , build_norm_layer () and build_activation_layer (). Webpytorch常用normalization函数. 将输入的图像shape记为，这几个方法主要的区别就是在， batchNorm是在batch上，对NHW做归一化，对小batchsize效果不好； layerNorm在通道 …
