wikingsonney2k: eeeey!!!01:38
wikingsonney2k: just realised why submodule will be really bad for unit testing01:38
wikingsonney2k: it's gonna be way too complicated to keep the unit testing in synch with shogun itself01:39
wikingsonney2k: say you want change some classes in shogun, you push it01:39
wikingthen you have to push separately in the submodule01:39
wikingsince if you not, and most of the developers won't as they will not be able to put in 1 PR the new code + the unit tests for it01:40
wikingthe unit testing will keep on failing...01:40
wikingthis my 2 cents ;P01:45

wikingn4nd0 yes12:42
wikingblackburn: ping?12:55
blackburnpong12:55
wikingblackburn: would u consider using this lib: http://code.entropywave.com/orc/12:56
blackburnwhat for?12:56
wikingblackburn: well behind SGVector12:57
wikingand SGMatrix12:57
blackburnwell we have eigen3 for that I think12:57
wikingblackburn: mmm that's not replacement :)12:57
blackburnwiking: I don't understand what is it then :)12:58
wikingblackburn: fuckshit i'm wrong12:58
blackburnso if we optimize inner loops with SIMD12:58
wikingi mean half12:59
wikingwrong12:59
blackburneigen3 does the same via any available SSE12:59
wikingso orc is runtime optimizer12:59
blackburnrun-time? oh12:59
wikingblackburn: does eigen do it runtime? afaik it's compile time no?12:59
blackburnwell12:59
blackburnfor variable size arrays it does splitting to 128 bits long parts13:00
wikingmmm that makes me wonder13:07
wikingwhere's the -DHAVE_EIGEN3 flag13:07
wikingwhen i compile :S13:07
blackburnwiking: was it detected on configure?13:08
-!- uricamic1 [~uricamic@2001:718:2:1634:b07b:e85b:8940:fa6f] has joined #shogun13:08
wikingblackburn: fuck it's not detected13:08
wikingblackburn: i'll fix the configure script :P13:08
blackburnwiking: config script is ok I think13:08
wikingblackburn: one flag is missing :S13:09
blackburnwhich one?13:09
wiking-I13:09
wikinginclude flag ismissing there13:09
blackburnhmm13:09
blackburnokay13:09
wikingblackburn: btw why dont u detect it via13:09
wikingpkg-config ?13:09
-!- uricamic [~uricamic@2001:718:2:1634:4c95:e117:3805:c6f] has quit [Ping timeout: 245 seconds]13:10
wikingblackburn: as eigen3 supplies pkg-config files13:10
blackburnwell it is something common to do that this way in our configure13:10
blackburnI don't know13:10
wikingblackburn: configure script checks for pkg-config13:10
wikingindeed13:11
wiking 522     die "pkg-config not detected (required)"13:11
wikingblackburn: mmm13:17
wikingblackburn: where do u include eigen3 apart from Math.h?13:19
blackburnwiking: only in math13:19
blackburnit should be included only once to support preprocessor directives13:19
wikingok13:19
wikingblackburn: eigen headers should be included only by Eigen/...13:20
wikingblackburn: i've just checked the docs13:20
wikingof eigne13:20
blackburnyeah I think so too13:20
blackburn:)13:20
wikingok13:20
wikingdone13:20
wikingit works now13:20
blackburnwell probably there is a need to add proper include13:21

n4nd0wiking: I wanted to comment something about the PR for the testing unit15:28
n4nd0wiking: but let me first to read the last comments in the PR15:28
wikingn4nd0: just a sec i'm on skype15:29
wikingi'll be back in 1015:29
n4nd0ok15:29
n4nd0ok, heiko and you have already been talking about my concern15:31
n4nd0I think the best option is to use another branch, as you suggested in the PR15:32
wikingn4nd0: ok sorry i was awway15:43
wikingbut now back15:44
wikingyeah just put there your opinion as well about submodule vs having it in the main repo15:44
wikingn4nd0: i have a question related to PrimalMosekSVM15:45
wikingi'll dig it out now just a sec15:45
n4nd0wiking: ok15:45
n4nd0wiking: I am updating that class right now by the way15:45
wikingn4nd0: ok let me know how15:45
wikingmy concern is about argmax in StruturalModel15:46
n4nd0there was something that is required for the HMSVM but was not regarded at the beginning15:46
n4nd0ok, tell me about it first15:46
wikingis that the function for you that finds \hat{y} for you?15:46
wikingif i'm not clear what i'm talking about here. just a sec to dig out the equation15:47
n4nd0yes, it is15:47
n4nd0you can think of it too as the function you use to make predictions (the common apply we have in other machines)15:48
n4nd0CLinearStructuredOutputMachine::apply_structured is simply calling this argmax15:49
wikingn4nd0: but when you do the learning15:50
wikingi mean training15:50
wikingit's called as well afaik15:50
n4nd0yes15:50
n4nd0since it is a cutting plane algorithm15:51
wikingyep15:51
wikingcool15:51
wikingthen we'll only need to do a new EnumType for strutural learners :P15:51
n4nd0yeah why not15:52
wikingi'll need it in LatentSOSVM15:53
wikingso that user can choose between solvers15:53
n4nd0aham15:53
n4nd0the LatentSOSVM inherits from?15:54
wikingi thought first about relying on user to supply the so solver15:54
wikingbut then i thought that it's going to be too complicated.. and just go with simply setting the solver type15:54
wikingand i'll do internally everything for the 2 different solvers15:54
wikingit's inherited from LinearLatentMachine15:54
wikingso has nothing to do in a way with StructuredOutputMachine15:55
n4nd0ok15:55
wikingit'll just contain a CLinearStructuredOutputMachine15:55
wikingbut that's going to created runtime15:55
n4nd0aham, no instantiation of it in the constructor you mean?15:56
wikingyes15:56
wikingindeed15:56
wikingit'll be created in the train_machine function15:56
n4nd0ok15:56

blackburnwell  actually I don't think it is so brute23:32
* wiking runs away in shame :S23:34
wikingi mean it's just that it was said that 'no lapack and such in .h'23:34

wikingstraight into .cpp23:35
wikingno?23:35
blackburnto each cpp?23:36
wikingwell yep23:37
wikingif we strictly speaking about this 'no lapack and such ifdefs'23:37
wikingthen yeah23:37
wikingeach time u use it somewhere23:37
wikinginclude it23:37
blackburnproblem is that in case of some cross-dependency or so23:38

yoogood evening all23:54
blackburnhey23:54
yoocould someone give me plz a small example for iterate over CFeatures or print CFeatures.23:55
yooI have seen get_next_feature and get_feature_iterator but ..23:56
yoo(c++)23:56
yooI try something like :23:57
yoovoid *iterator; float64_t val; int32_t j;             wdfeats->get_feature_iterator(j);             while (wdfeats->get_next_feature(j, val, iterator)){                std::cout << val << std::endl;             }             wdfeats->free_feature_iterator(iterator);23:58
yooouch sorry for that23:58
yoomore like that : http://pastebin.com/uYMQr8TW23:58
blackburnyoo: well iterators are pretty crappy way here23:59
blackburnthey are here just for some compatibility23:59
blackburnwhat exactly do you need?23:59
yooyes thats why I ask :p23:59
yoojust iterate and print features23:59
