excuse me,I am currently reading about the code of corner pooling layer,I think I understand the forward of the corner pooling ,but i don't quite understand the backward ,could you Explain the general process of backward?

It's similar to the conventional max pooling. The gradients back propagate through the neurons that achieve the maximum values.
