Hey guys, I have observed a thing here that I want to discuss and clarify about. Lets say you have a tensor h**2 so h**2>=0 also you have a kernel whose values are all non-negative. w>=0. Now, when I do the convolution operation F.conv2d(h**2,w), the result is all non-negative.
However, when do the same operation with padding=1, i.e, F.conv2d(h**2,w,padiing=1), I am getting some negative values as well which i checked by doing
assert torch.all(F.conv2d(h**2,w,padding=1)>=0)
Why does padding affect the sign change?
