16:29 < ShikharJ> zoq: I'm struggling a bit in understanding the present layout of the `Gradients` code for the convolution layer. Why is the size of the `mappedError` reduced in the presence of padding?
16:56 < zoq> ShikharJ: Good point, that's an issue in the implementation.

17:18 < ShikharJ> zoq: The way I see it, for a simple non padded case, we are taking input A, convolving with kernel B to get the output C. Then were, taking A again and convolving with the differences (which have the same shape as the output) and getting the output the shape of B, and updating it?
17:21 < zoq> ShikharJ: Yeah, that's the pipline.
17:22 < ShikharJ> Then shouldn't it be the same for the padded case?
17:23 < zoq> ShikharJ: Yes, can't think of any reason to resize the error, so I think you found a bug.
17:33 < zoq> I think we should write another test case and fix this, I can do this, just let me know.
17:36 < ShikharJ> Sure, I'll be busy with the transposed convolution layer testing (which I wish to finish today). Thanks for the help :)

19:43 < zoq> On a second thought, it makes sense to reduce the mapped error, since we are updating against the non-padded input, but I think this can be simplified.
