10:10 < tejasvi[m]> zoq Why paddings are asked in the constructor of covolution layer only to be ignored later?

10:14 < PrinceGuptaGitte> I have a question:
10:14 < PrinceGuptaGitte> If I have two arms matrices say x and y
10:14 < PrinceGuptaGitte> And I do y / x. The elements where x is 0 will become nan
10:15 < PrinceGuptaGitte> Can I avoid it without explicit loop(to sa e performance)
10:15 < PrinceGuptaGitte> Nevermind I figured it out just now, just when I gave up. Sorry for unnecessary bothering
10:23 < zoq> tejasvi: ItÃ's not ignored, we just use: https://github.com/mlpack/mlpack/blob/master/src/mlpack/methods/ann/layer/convolution_impl.hpp#L70

10:34 < LakshyaOjhaGitte> Hey I think that in my [pr](https://github.com/mlpack/mlpack/pull/2174) the checks are stuck somehow.
10:34 < LakshyaOjhaGitte> How do I restart them?
10:36 -!- tejasvi[m] [tstomarmat@gateway/shell/matrix.org/x-gghajbqiptwzqtum] has joined #mlpack
10:36 < tejasvi[m]> zoq But later on, in 'valid' case it is set zero and for 'same' InitializeSamePadding() sets the padding using the formula.
10:37 < tejasvi[m]> https://github.com/mlpack/mlpack/blob/master/src/mlpack/methods/ann/layer/convolution_impl.hpp#L451
10:37 < zoq> LakshyaOjha: Let me restart the build for you.
10:38 < zoq> tejasvi: Have to take a closer look.
10:38 < tejasvi[m]> zoq: Oh, got it now. I was ignoring 'none' padding
10:40 < LakshyaOjhaGitte> @zoq Thank you!

17:16 < LakshyaOjhaGitte> @zoq can you check the soft shrink activation function [pr](https://github.com/mlpack/mlpack/pull/2174) please.
17:22 < jeffin143[m]> @jonpsy : hi , welcome :)
18:36 < kartikdutt18Gitt> Hi @zoq, @rcurtin when you get a chance have look at https://github.com/mlpack/mlpack/pull/2178#issuecomment-583543802
18:38 < PrinceGuptaGitte> hi @kartikdutt18, In #2184 you mentioned that inverse may get division by zero. I thought of a way to avoid it rather than throwing fatal error. I replied, please look into it when you get time
18:39 < kartikdutt18Gitt> Sure I will take a look. Thanks.
19:12 < zoq> Mrityunjay: Hello, will take a look once I have a chance.
