striding layers 是什么意思？

第一句

We adapted the VGG-16 network (Simonyan & Zisserman, 2015) for dense prediction and removed the last two pooling and striding layers.

第二句

Specifically, each of these pooling and striding layers was removed and convolutions in all subsequent layers were dilated by a factor of 2 for each pooling layer that was ablated.

第三句

Most significantly, we remove the last two pooling and striding layers entirely, whereas Long et al. kept them and Chen et al. replaced striding by dilation but kept the pooling layers.

做者把pooling和striding两个单词是一块儿用，也便是卷积网络中池化和子采样层是分别实现的，固然如今通常理解为一块儿，由于pooling中通常stride=2。那么pooling中的stride=1，结合padding的话，彻底能够作到保持feature maps大小不变。其实pooling彻底能够理解为conv。
