striding layers 是什麼意思？

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兩個單詞是一塊兒用，也便是卷積網絡中池化和子採樣層是分別實現的，固然如今通常理解爲一塊兒，由於pooling中通常stride=2。那麼pooling中的stride=1，結合padding的話，徹底能夠作到保持feature maps大小不變。其實pooling徹底能夠理解爲conv。
