10:58 < zoq> thepro: Hello, not sure what you mean with ANN programs; mlpack implements building blocks, to create various network structures.

10:59 < thepro> ones which have their basis on neural nets.
11:02 < thepro> I got what you want to say.
11:02 < thepro> thanks

11:13 < zoq> Okay, I guess if the questions is, does mlpack implement conv nets, forward networks, recurrent networks, the answer is yes.

13:44 < Atharva> Even when I use const int in place of int, Jenkins style check still tells me that I am using variable length arrays.
13:44 < Atharva> Can someone help me here - it says - Do not use variable-length arrays. Use an appropriately named ('k' followed by CamelCase) compile-time constant for the size.
13:48 < zoq> Can you pont me to the PR?

13:54 < zoq> You can probably use .set_size(...).
13:56 < Atharva> #1263, okay I will try that
13:57 < zoq> I see, yeah using arma::mat[size] isn't common.
14:00 < Atharva> Should I use constexpr for compile time constant?
14:02 < zoq> No need to use constexpr inside a test method.
14:03 < Atharva> Then what do you suggest?
14:04 < zoq> const constantName = value; is just fine
14:04 < zoq> but if you like to use constexpr feel free.
14:06 < Atharva> but using const still fails the style check, I will try constexpr then. Can I ask why you were reluctant to suggest constexpr?
14:06 < Atharva> Is it something specific about it?
14:08 < zoq> There is no specific reason.
14:08 < Atharva> Okay :)
14:14 < Atharva> So even using constexpr fails the style check, same error.
14:15 < Atharva> I think it's because I am using sizeof while defining it, so it never runs at compile time.
14:16 < Atharva> Should I just manually enter the number instead of using sizeof?
14:17 < zoq> We are talking about http://masterblaster.mlpack.org/job/pull-requests%20mlpack%20style%20checks/1756/cppcheckResult/source.all/?before=5&after=5 right?
14:17 < zoq> Can't see any constexpr issues.
14:17 < Atharva> Yes, that is the one
14:18 < zoq> As I said either use set size or use the arma::mat constructor to set the size.
14:19 < zoq> Also, it looks like you like to store matrices, so either use arma::cube or std::vector
14:21 < zoq> std::vector might be the easiest solution
14:22 < zoq> so something like: std::vector distances; distances.push_back(...);
14:22 < Atharva> Okay, thanks
14:22 < Atharva> I will use std::vector
14:25 < Atharva> I think another approach in that particular case will be not store matrices at all, I can just check if they are equal two at a time and just overwrite the previous ones I don't need
14:26 < zoq> good idea

19:08 < haritha1313> sumedhghaisas: Hi, I had a doubt regarding the SVDWrapper implemented in cf. I don't see that any SVD method being used by CF is using the wrapper.
19:11 < haritha1313> I am trying to enable using quic_svd as a MF method in CF and have a PR open for it. I am not sure whether I should use the wrapper or rather stick to writing function for the same in cf_impl.cpp since no other SVD method seems to be using it.
