pytorch方法测试详解——归一化(BatchNorm2d)
torch.nn.BatchNorm2d的weight和bias分别是用于归一化的权重和偏置项。在Batch Normalization中,weight用于缩放归一化的结果,而bias用于平移归一化的结果。权重和偏置项可以通过设置affine参数为True来启用,默认情况下为True。具体来说,weight用于调整归一化后的特征图的尺度,而bias用于调整特征图的偏移。通过调整权重和偏置项,我们可以对归一化结果进行进一步的灵活调整,以适应不同的网络结构和任务需求。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
