11:42 < namratamukhija> The issue I am facing is this: I wrote some binding test cases for approx KFN. I am trying to compile them with the command: g++ approx_kfn_test.cpp -o object -std=c++11 -lmlpack -larmadillo -lboost_serialization -lboost_program_options -lboost_unit_test_framework.

12:13 < bhuwnesh> I mean that for the decision trees can I implement the above mentioned algorithms along with CART and C 4.5 with few changes.

14:06 -!- manish729429 is now known as manish7294
14:10 < rcurtin> manish7294: I actually glanced at it yesterday because I was interested to see how many proposals had already been submitted; I think it is clear and put together well
14:11 < rcurtin> my only thought was, it's not guaranteed that LMNN+LRSDP will work, so probably ensuring that LMNN can work with the other SDP solvers we have would be a good first test
14:11 < rcurtin> but I am not sure I looked closely enough to see if that detail was already there
14:11 -!- mrcode [~thelaughi@216.162.154.73] has quit [Quit: Leaving.]
14:16 < manish7294> rcurtin: Thanks for reviewing it. Your concern is up to the point as currently there is no work in this regard. Currently, I have put together a standard LRSDP form for the same and hoping that it will work.
14:17 < manish7294> I will try checking it with other SDP solvers in the meantime.

14:18 < rcurtin> keep in mind we do have a primal-dual solver, so I think it would not be too hard to implement the SDP problem itself for LMNN and then use any of the solvers

14:41 < Atharva> rcurtin: Does it matter how early the proposal is submitted before 27th?

14:53 < zoq> Atharva: No, but don't expect feedback on a proposal submitted days before the deadline; the review process comes on top of the things we are trying to manage right now.
14:55 < Atharva> zoq: Okay, so can I get feedback even after I have uploaded the proposal on the portal?
14:56 < rcurtin> Atharva: we can try and give feedback if we have time, but I don't think we can make any guarantees
14:56 < zoq> Right, also we will only review proposals that are accessible via the dashboard, I think you have to mark your proposal as final at the end.
14:56 < rcurtin> typically the most important things for a strong proposal is to make sure that the timeline is clear, to make sure the work you are proposing to do is clear, and to make sure that whatever you are proposing will be a useful and user-accessible part of the library when it is done

14:58 < Atharva> Okay, thank you, I will upload my proposal by this weekend, about 17th March, I hope it isn't very late.
14:59 < Atharva> Also, will only the mentors of that particular project review it?

15:09 < zoq> ShikharJ: I can access the draft.

16:57 < thepro> hello
16:58 < zoq> thepro: Hello there!
16:58 < thepro> the implementation of the decision tree says it is the generic tree classifier. Is generic referring to ID3 algorithm?
17:00 < zoq> thepro: C4.5, https://github.com/mlpack/mlpack/pull/858
17:01 < thepro> thanks
17:02 -!- sourabhvarshney1 [0e8b7937@gateway/web/freenode/ip.14.139.121.55] has quit [Ping timeout: 260 seconds]
17:16 < thepro> do mlpack have an existing implementation for ID3?
17:20 < rcurtin> thepro: ID3 was originally written for only categorical attributes in the paper, so really what I would say is that mlpack's implementation closely resembles the later C4.5 tree building strategy with a few optimizations and minor changes
17:20 < rcurtin> note also that C4.5 is a newer version of ID3, so the two are closely related
