Inception residual block的作用

WebWe adopt residual learning to every few stacked layers. A building block is shown in Fig.2. Formally, in this paper we consider a building block defined as: y = F(x;fW ig)+x: (1) Here x and y are the input and output vectors of the lay-ers considered. The function F(x;fW ig) represents the residual mapping to be learned. For the example in Fig.2 Web对于Inception+Res网络,我们使用比初始Inception更简易的Inception网络,但为了每个补偿由Inception block 引起的维度减少,Inception后面都有一个滤波扩展层(1×1个未激活的卷积),用于在添加之前按比例放大滤波器组的维数,以匹配输入的深度。
