Hey zoq rcurtin do we have implementation flatten layer in ann module
< HimanshuPathakGi>
I try to find it but not there in layer
< kartikdutt18Gitt>
Hi @himanshupathak21061998, I don't think we have flatten but its simply resizing the output cube/mat to given number of channels. I think its more related to armadillo than ann.

HimanshuPathak: Internally, everything is just continuous memory, so if you need to flatten the input/output you could always do something like: arma::Mat(input.memptr(), 1, input.n_elem()), and that will give you a flattern version of the input whitout any speed penalty.

Hi everyone, during the past few days I was getting acquainted with the mlpack repository and to contribute it by implementing the GELU activation function. Should I go ahead and open an issue and start working on it?
< zoq>
GauravSingh: Hello, sounds good please feel free to open an issue and a PR.

@zoq I was thinking to start working on mlpack cmake
< zoq>
Nakul[m]: If you are down for a challenge, the bindings part might be tricky.
< kartikdutt18Gitt>
Hi @zoq, if you get the chance kindly have a look at PR #38 in models repo, I made the changes you requested in the same.Thanks.
< zoq>
kartikdutt18: will do
< Nakul[m]>
Here someone doing something for visualization ? Just curious

Thanks zoq I will try this arma::Mat(input.memptr(), 1, input.n_elem()) next time.

Hi, I have a question regarding activation functions.
< PrinceGuptaGitte>
Currently the deriv() function takes input y then calculates f'(x) where f(x) = y
UmarJ has joined #mlpack
< zoq>
PrinceGupta: right
< zoq>
PrinceGupta: f'(f(x) )
< zoq>
PrinceGupta: I see the comment is confusing.
< kartikdutt18Gitt>
Hi @prince776, I think you are right, that's a typo.
< PrinceGuptaGitte>
Hi, I implemented ISRU function for issue #2181 but when I built it, it didn't build the new create file isru_function.hpp, am I missing something?
< kartikdutt18Gitt>
Hi I think you didn't add in cmakeFile.txt
< zoq>
kartikdutt18: Yes, once I have a chance I will look into it and leave a comment.

Error : Unable to locate package libstb-dev

@kartikdutt18
< zoq>
Abhinavverma: Not sure there is a libstb-dev package, isn't it header only? Anyway, if you buld mlpack using cmake, it will download the file for you.
< kartikdutt18Gitt>
I think libstb-dev is only available in (very) recent versions of ubuntu (I referred this https://pkgs.org/download/libstb-dev )
< PrinceGuptaGitte>
@zoq yea it really confused me about how it's working. I had to look into other activation function files and base_layer to confirm.
< AbhinavvermaGitt>
@kartikdutt18 I have already checked this link before there is no version for 32 bit.
