减少了参数数量:相比于传统的网络结构,ResNet-18 的残差块允许跳跃连接,使得网络可以跳过一些不必要的卷积层,从而减少了参数数量,减轻了过拟合的风险。 在计算资源允许的情况下,可以通过增加网络的深度进一步提升性能:ResNet-18 可以作为基础模型,通过增加残差块的数量或者使用更深的变体(如 ResNet-34、ResNet-50 ...

Wideresnet50是在ResNet50的基础上进行改进和优化得到的,它的层次结构如下所示: 1. 输入层:Wideresnet50的输入层接受图像作为输入,图像通常由像素矩阵表示,每个像素包含图像的红、绿、蓝三个通道的数值。 2. 卷积层1:Wideresnet50的第一个卷积层对输入图像进行特征提取。该层通常包含多个卷积核,每个卷积核负责...

WideResNet论文中的图解进一步解释了网络构建逻辑。WideResNet包含一个初始Stage（conv1），将输入图像从3通道转换为16通道，以及3个Stage的层（conv2、conv3、conv4）。每个Stage内包含一个1*1卷积操作以及2N个3*3卷积层。总计，WideResNet拥有6N+4个卷积层。这里的“depth”指的是卷积层的数量。初...
