02:25 -!- Irssi: #mlpack: Total of 96 nicks [0 ops, 0 halfops, 0 voices, 96 normal]
02:25 < rcurtin> birm[m]1: for now we added an azure workaround in #2306, so if branches merge from master then they should trigger azure for a rebuild
02:26 < jeffin143[m]> Rcurtin : how do we create variable length columns in armadillo ???
02:26 < rcurtin> jeffin143[m]: that's not possible with arma::mat, to do that would require the use of arma::field
02:27 < rcurtin> (alternately, consider 'std::vector<arma::vec>' or something?)
02:27 < rcurtin> if this is about the column-major string encoding, I do think that whatever you're doing now can just be transposed with no issue
02:27 < jeffin143[m]> Because in string encoding we give output as without padding , that means variable length rows , but how do we that in vectors
02:27 < jeffin143[m]> Ok I will just take a look
02:27 < jeffin143[m]> Then
02:27 < rcurtin> hmm, I think we would need padding in this case
02:28 < jeffin143[m]> Can we follow this approach ,. Merge string encoding as this and then refactor ? If you don't mind
02:28 < rcurtin> in this case I think I'd rather wait, since the current string encoding is "backwards" and wouldn't give results that are ready to use with other mlpack code
02:29 < rcurtin> really there's no hurry---we can easily release another one as soon as those are in
02:29 < rcurtin> (I say this a lot, so I hope it still means something, but I really would like to have significantly more frequent releases for mlpack)
02:29 < rcurtin> (perhaps not quite every PR, which is basically the ensmallen release cycle, but certainly every couple weeks. the 3.3.0 release has been slow since it was held up on Julia)
02:29 < jeffin143[m]> Ok , then I will take time and see into this issue
02:30 < rcurtin> yeah, there is no hurry, don't worry :)
02:30 < rcurtin> anyway, it's late here---I'm going to head to bed. 'night!
02:30 < jeffin143[m]> Good night

10:48 < favre49> Well I think it's fixed... I've probably jinxed it now though

12:02 < hemal[m]> I've shared my proposal draft for review through GSoC portal. @zoq @rcurtin please provide your reviews whenever you get time.
12:02 < hemal[m]> Proposal Topic: Graph Convolutional Network (GCN)
12:02 < hemal[m]> Thanks.
12:04 < hemal[m]> jeffin143: thanks for sharing the article!

12:13 < rcurtin> hemal[m]: thanks for letting us know, but I'll just be honest and say that I'm not going to have any time to provide a review
12:13 < rcurtin> there's no way, given the huge amount of open PRs and other requests

12:15 < pickle-rick[m]> rcurtin: Should I send an email to the mailing list with a summary of my proposal? Or should we just submit the proposal through the GSoC portal, and hope for the best, since everyone will be busy with reviewing PRs and stuff?
12:15 < hemal[m]> rcurtin: thanks for letting me know
12:15 < hemal[m]> I'll Review some PRs to reduce some of the workload. 🙂

12:18 < zoq> pickle-rick[m]: You can directly send it to the GSoC portal, we we have time we can provide feedback over there.
12:19 < zoq> hemal[m]: Please feel free, any help is very much appreciated.
12:21 < pickle-rick[m]> <zoq "pickle-rick: You can directly se"> zoq: Thanks! Good to know.

12:22 < zoq> PrinceGuptaGitte: Maybe t he kernel size is wrong, did you build with DEBUG=ON, also might be good to step through the code with gdb.
12:23 < PrinceGuptaGitte> I didn't build with DEBUG=ON, should I do that while building mlpack?
12:24 < zoq> PrinceGuptaGitte: Yes, that enables bounds checks.
12:24 < PrinceGuptaGitte> Thanks, i'll try that
12:26 < kartikdutt18Gitt> Hi @prince776, it might be related to this [comment](https://github.com/mlpack/models/issues/63#issuecomment-599199730). Not really sure though. Hope it helps.

14:51 < zoq> So with #2278 merged the macOS build should be fixed, great work Yashwant!
14:53 < rcurtin> agreed, thank you!

19:06 -!- LayMann [676aeae3@103.106.234.227] has joined #mlpack
19:09 < LayMann> hey are there qualification rounds or should i debug and PR something
19:12 < zoq> LayMann: Hello, what do you mean with qualification rounds?
19:13 < LayMann> i meant sometimes there are tasks given by an organization to filter the students
19:13 < zoq> We don't require a contribution to be considered for GSoC.
19:13 < zoq> There are some open issues, if you find something intersting, please feel free to work on it.
19:14 < LayMann> so i should just write a proposal then
19:14 < LayMann> ?
19:14 < zoq> Also there are open PR's that are waiting for a review, so if you like to help with a review, that's another great way to get familiar with mlpack.
19:16 < zoq> You can, submit your proposal right away yes, it's certainly a great idea to get familiar with the codebase as well.
19:17 < zoq> One question we often ask is how does this integrate into the codebase, that's difficult to answer if you haven't looked into the project.
19:22 < LayMann> reinforcement learning is still an active project right?
20:13 < zoq> LayMann: yes

20:47 < M_slack_mlpack13> I'm interested in working on reinforcement learning project and would like to contribute for ACKTER and Persistent Advantage Learning DQN algorithm. In the proposal should I need to mention all the technicalities after going through the required code base or should I need to mention brief workflow about how I'm going to implement in 12 weeks time?
