@sonney2kI never think hard00:00
shogun-buildbotbuild #1125 of deb3 - modular_interfaces is complete: Failure [failed test libshogun]  Build details are at http://www.shogun-toolbox.org/buildbot/builders/deb3%20-%20modular_interfaces/builds/1125  blamelist: Sergey Lisitsyn <lisitsyn.s.o@gmail.com>00:00
@lisitsynI hardly think hard00:00
@sonney2kI am just too soft00:00
@lisitsynthen I fall asleep00:00
@lisitsynsonney2k: okay one solution00:01
@lisitsyna) add a base class like DenseFeaturesDataKeeper00:02
@lisitsynb) inherit a template class from it00:02
@lisitsync) add constructors for densefeatures for all supported types00:02
@lisitsynwhere we create appropriate data keeper00:02
@sonney2kyeah void* would be a solution00:02
van51sonney2k: I think the problem is when you call DynArray::insert_element and the array is empty00:02
@sonney2kvan51, very well possible00:03
@lisitsynsonney2k: not really voide00:03
@lisitsynvoid*00:03
van51after it has at least one element it's ok00:03
@sonney2kvan51, plesae write a unit test and fix it00:03
@lisitsynsonney2k: let me try that this weekend and we will see00:04
@sonney2kvan51, I think it is also troublesome to call insert_* with an index >= number_of_elements00:04
van51sonney2k: ok, but can it wait until tomorrow?00:04
@lisitsynsonney2k: do you expect really significant speedup with that?00:04
@sonney2klisitsyn, with what?00:05
@lisitsynsonney2k: with no templates exposed00:05
@sonney2ktemplate removal?00:05
@sonney2klisitsyn, just try it00:05
@sonney2kremove all %template from .i00:05
van51sonney2k: I was thinking about that, but I didn't see any index checks on the array classes00:06
van51so I thought it was up to the user to do it correctly00:06
@sonney2kvan51, yeah it was intended like this00:06
van51sonney2k: I'll try and fix it tomorrow00:08
van51and will provide some unit tests00:08
@lisitsynsonney2k: what do we lost this way is compile time typechecking00:09
@lisitsynwhich is relevant for C++00:09
@lisitsynI mean if I add that thing we get runtime typechecking00:12
@lisitsynbut if you do sth like set_feature_vector(some sgvector of wrong type)00:12
@lisitsynyou get no error in C++00:12
@iglesiasggood night guys, I am falling asleep on the keyboard :D00:13
@lisitsyniglesiasg: same here actually00:13
@lisitsyngood night00:13

@wikingsonne|work: ping? shall we have a c4.5 and c5.0 implementation in shogun... as i'm now starting from scratch the random forest implementation so i realised that it's good to have decision trees implemented10:58
@wikingsonne|work: moreover: do anybody is planning to do this in gsoc? so just that i dont take somebody's project...10:58
sonne|workwiking: well there is no OSS implementation of C4.5 and C5.0 code is only slightly better den cat /dev/unrandom10:59
sonne|workwiking: but yes feel free10:59
sonne|workwiking: you could port weka's j45 over to shogun11:00
sonne|workmight be the most readable...11:00
@wikingsonne|work: yeah i want first random forest ASAP11:00
@wikingbut then i'll do some other tree implementation as well11:00
sonne|workwell random forest == some tree impl but just bagged on top11:01
@wikingyeps11:01
sonne|workI think the correct approach would be11:01
sonne|workto do a BaggedClassifier11:01
sonne|workthat just trains the same classifier a couple of times11:01
sonne|workusing some sampling scheme11:02
sonne|workof the training data points11:02
sonne|workthen you can fit in *any* other classifier11:02
sonne|worklike svm / tree / knn11:02
sonne|workand you have your random forest as subset11:02
@lisitsynheyya11:02

lambdaylisitsyn: hi13:09
@lisitsynlambday: hey13:09
lambdayI did a rebase... and after that doing make-unittests gives an error.... apparently CMath:init_random has been changed..13:10
lambdaywait let me paste13:10
@lisitsynyeah that would be better13:10
lambdayIn function `shogun::CMath::init_random(unsigned int)':13:10
lambdayIn function `shogun::CMath::init_random(unsigned int)':13:10
lambdayshit... wait!13:10
lambdayMath.h:458: undefined reference to `shogun::CMath::rand_state13:11
lambdaybut now its been replaced with something else, I just checked13:11
foulwallsonne|work: sonney2k, could I start a django app for each demo, or make a classification such as supervised, unsupervised etc and start apps for each of it , or just start a 'demo' app and include all the demos in it?13:11
@lisitsynlambday: did you try to clean up that thing? sounds like something related to recent changes in random13:12
lambdaywhy it would give this error then? I freshly did a make and my src shows new CMath13:12
lambdaylisitsyn: I did git pull --rebase upstream develop, and the make clean and make13:13
lambdaylisitsyn: yes... seems so13:13
@lisitsynI think not all things are properly updated in tests13:13
lambdaylisitsyn: I think the unit-tests just makes a init_random() call... whose definition in CMath has been changed... should be fine, right?13:14
@lisitsynlambday: so did clean help13:15
@lisitsyn?13:15
lambdaylisitsyn: nope! :(13:15
@lisitsynehmm13:15
lambdayclueless :-/13:15
lambdayshall I try cloning somewhere else and then rebase and test again?13:16
@wikinglambday: actually init_random did not change13:16
@lisitsynlambday: no makes no sense for me13:17
@wikingit's just PRNG behind it is changed13:17
@wikingbut the API is the same13:17
lambdaywiking: hmm... the error shows undefined reference to CMath::rand_state, I checked and it was there previously, now changed13:18
@wikingyes13:18
@wikingbut then you have a problem13:18
@wikingthat you dont have the latest CMath.h/cpp13:18
lambdaywiking: I do :( I checked and it shows the new init_random()13:20
lambdaytotally weird :-/13:20
lambdaymay be I'm doing something wrong - let me check again13:20
sonne|workfoulwall: I single demo app is totally sufficient13:22
sonne|workfoulwall: you just need to 'mirror' the urls we have currently in your stuff13:22
foulwallsonne|work: ok...13:22
sonne|worklambday: maybe better do a git clean -dfx (will erase anything not in git)13:23
sonne|workrecompile / install / run tests13:23
lambdaysonney2k: okay.. thanks... trying13:24

hao_Good morning everyone.14:07
sonne|workhey there14:07
hao_well I am an applicant of google SoC.14:08
hao_And I contacted with my mentor, some days ago. He told me to make some contribution on the issues on git14:09
hao_But only from the name of the issues, I am not sure which one will fit me and I can really make some help.14:10
hao_And I choosed one, but found there is already some one working on it.14:11
hao_So I find it may be better choose one issue after asking around.14:12
hao_Would anyone here please recommend me some issues or works to work with?14:12
@iglesiasghao_: Is there any of them which interests you?14:13
hao_Import eliptic curve functions, but lambday is working on it.14:15
hao_http://www.google-melange.com/gsoc/proposal/review/google/gsoc2013/ylyhlh/400114:15

vgorbatilisitsyn: I see you have merged a PR so fast:) Should I take now a task from HeikoS as we discussed?14:31
@lisitsynvgorbati: yeah please ask them for some task14:31
foulwallsonne|work: https://github.com/foulwall/shogun_demo, I've finished and created a repo.14:32
@lisitsynvgorbati: https://github.com/shogun-toolbox/shogun/issues/110214:32
@lisitsynwhat about it?14:32
vgorbatilisitsyn: I guess I need a bit more info about what needs to be done:)14:33
sonne|workfoulwall: ok nice I will move that then to the official shogun toolbox repository. now I only need a patch that removes the demos from shogun-web14:33
@lisitsynvgorbati: ask sonne|work but in general it should be something like just remove the method and resolve all errors14:33
sonne|workexaclty14:34
foulwallsonne|work:  ok I'll send a pr on shogun-web14:34
sonne|workexaaaactly14:34
sonne|workfoulwall: thanks14:34
vgorbatisonne|work: so I will need to find all places where this method may be used and replace it by appropriate method calls?14:35
sonne|workfoulwall: I think we should start to use some of shogun's data sets for illustration14:35
sonne|workvgorbati: drop die this method14:35
sonne|workno one should use it14:35
foulwallsonne|work: ok14:35
sonne|workvgorbati: shoot, remove!14:35
vgorbatisonne|work: :)ok, understood:)14:35
vgorbatiI guess it won't be that hard:)14:36
sonne|workfoulwall: you could add support to load the data sets under toy/ from there14:37
sonne|workthen just plot the first 2dims of that data set14:37
sonne|workand then any method could use them14:37
sonne|workfoulwall: like you have now 'artificial' genatore14:37
sonne|workgenerator14:37
sonne|workmanually clicked14:38
sonne|worknow in addition data loaded14:38
sonne|workfoulwall: so you need some kind of re-usable component that you can display on any website for this14:38
foulwallsonne|work: you mean data in https://github.com/shogun-toolbox/shogun-data?14:38
sonne|workfoulwall: I like your -1, +1 plot the most so all could just use this14:38
sonne|workfoulwall: yes14:38
foulwallsonne|work: Ok! I'll do have a look at this repo tonight and do it tomorrow14:39
sonne|workformat of that is not yet standardized but will happen this gsoc :)14:39
sonne|workfoulwall: thanks a lot14:39
sonne|workfoulwall: but you got the idea yes? some say drop down list - to let the user choose to manually do input / select a data file / randomly generate data14:40
foulwallsonne|work: I'll send some little patchs on the existing demo tonight. like when user move the mouse on the curve and show the coordinate14:41
foulwallsonne|work: I see.14:41
hao_Well. Is that possible to change the gsoc project? Because I guess the project I choosed has been filled.14:43
@lisitsynhao_: there is no project with no student at all :)14:44
hao_the result has almost been decided or not?14:45
@lisitsynhao_: well we definitely have some list of top candidates14:47
@lisitsynwe have to come up with the final decision on 22th I think14:48
hao_I see. kind of late to begin.14:48

@lisitsynhao_: https://github.com/shogun-toolbox/shogun/issues?state=open14:51
@lisitsynis there any issue you'd like to resolve?14:51

@lisitsynsonney2k: I mean we could go for breaking the things to stuff like shogun-liblinear etc21:20
@lisitsynI have no opinion on that21:22
@sonney2klisitsyn, there are a couple of issues21:22
@sonney2klots of stuff in shogun is very much connected21:22

van511so what were you saying? :)21:23
@sonney2kvan511, we are waiting for van511121:23
@sonney2kvan511, just hi21:23
van511i'll pass the info to him, don't worry21:23
@sonney2klisitsyn, so I don't really know how to split this stuff out21:23
@lisitsynsonney2k: me neither21:23
@sonney2kvan511, heh21:23
@lisitsynjust generating ideas as usual :D21:24
@sonney2kso lets say we woudl want to extract kernels into a separate lib21:24
@sonney2kwhat would we do?21:24
@lisitsynno no21:24
@lisitsynmakes no sesne21:24
@sonney2kwhy not?21:24
@sonney2kkernels are a submodule of shogun21:25
@lisitsynsonney2k: what we can extract are real algorithms21:25
@lisitsynthat's core21:25
@lisitsynkernel,distances,features21:25
@lisitsynthe mighty trio21:25
@sonney2kwe can only extract these algorithms if they are designed to be extracted21:25
@sonney2kconsider liblinear / libsvm21:25
@sonney2kwe cannot extract them21:25
@sonney2kwe have things in there like ctrl+c -> stop or continue21:26
@sonney2ktrainign time limit21:26
@lisitsynyeah true21:26
@sonney2kown kernels21:26
@sonney2kor even dot features21:26

@sonney2klisitsyn, e.g. ocas was designed with that in mind21:26
@lisitsynyeah same with tapkee21:26
@sonney2klisitsyn, because vojtech and me were working on it together21:26
-!- vgorbati [d4029f22@gateway/web/freenode/ip.212.2.159.34] has quit [Ping timeout: 250 seconds]21:27
@sonney2kand vojtech wanted ocas to be around also stand-a-lone21:27
@sonney2klisitsyn, about extracting kernels21:28
@sonney2kone could move the SG* datatypes into a separate lib that everyone then would use21:28
@sonney2kthen a kernel could just interface with these21:28
@lisitsynsonney2k: I seenothing special in SG* types21:29
@sonney2klisitsyn, we don't want features in kernels21:29
@lisitsynsonney2k: why?21:29
@sonney2kand kernels currently work with features21:29
@sonney2klisitsyn, if we split out kernels21:29
@lisitsynI don't really get that point21:29
@lisitsynwhy?21:29
@lisitsynwhy to separate them?21:30
@sonney2kkernels should be just kernels not kernels & features21:30
@lisitsynsounds pretty painful21:32
@sonney2kit is all painful21:33
@sonney2kthink about some library like say libsvm using other shogun classifiers as dynamically generated input21:34
@sonney2kthen we cannot extract21:34
@sonney2kthis whole module separation thing only works when you limit functionality21:34
@lisitsynsonney2k: yes we can't extract that21:34
@lisitsynyes sure21:34
@sonney2kmaybe not bad but one has to keep that in mind21:35
@lisitsynsonney2k: what is most important thing I see21:35
@sonney2kif we would really do it I would say each directoy in shogun should be a module21:35
@lisitsynvojtech maintains ocas21:36
@lisitsynI maintain tapkee21:36
@sonney2kyeah but if there is 0 interaction between the two it doesn't help us21:36
@sonney2ke.g. libsvm/liblinear21:36
@lisitsynyes sure21:36
@sonney2kwe take their code21:36
@sonney2kmodify it21:36
@sonney2kheavily21:36
@lisitsynwe have to modify their code yes21:36
@sonney2kbut that's it21:37
@sonney2kwe don't update and are not pushed to update21:37
@sonney2kand they don't care about our extensions21:37
@sonney2kit works fine with tapkee because you keep it up-to-date also wrt shogun interface21:37
@lisitsynyes I understand21:38
@sonney2kbut in the end it gives shogun not more - you work for tapkee and not directly on shogun21:38
@sonney2kif you were a non-core shogun author21:38
@sonney2kshogun would benefit21:38
@sonney2kbut yes that would be the way to go21:38
@lisitsynsonney2k: there are a lot of drawbacks in that for sure21:39
@sonney2ksomeone like you taking care of his own lib but who also wants to get exposure with shogun21:39
@sonney2kin addition ML people are like grass hoppers21:40
@sonney2kthey move from topic to topic in no time21:40
@lisitsynyeah21:40
@sonney2kand rarely want to maintain any code21:40
@sonney2kI recall the ML-OSS discussions we had in the workshops21:41
@sonney2kpeople said I give out my code sure but I don't want to support it21:41
@sonney2kand it is also different somehow - once an algorithm works it is finished21:42
@sonney2kfinal nothing more needed21:42
@sonney2kthere are only new algorithms improving that algorithm21:42
@lisitsynyou make me feel depressed :D21:42
@lisitsynusually i think there is no sense in all that stuff21:43
@sonney2kvotjakovr, please cheer lisitsyn up hand him a vodka or something21:43

@lisitsynsonney2k: what do you mean?21:44
@sonney2kit had the same effect on you :D21:44
@sonney2kno I think we have lots of cool algorithms already now but we really just need to expose them better21:45
@sonney2kand sure there always is algoirthm X doing somethign better for whatever use case21:45
@sonney2kor framework Y for some other usecase21:45
@sonney2kwe just have to find (and be satisfied with) our niche21:46

dvalcarcei will check user management23:13
-!- hushell [~hushell@8-92.ptpg.oregonstate.edu] has quit [Quit: leaving]23:14
@sonney2kdvalcarce, once you have sth I should create shogun-bakufu and we shoudl start merge things over23:15
dvalcarcesonney2k, right now (https://github.com/dvalcarce/shogun-bakufu) you can upload and delete documents23:16
van51sonney2k: so, the insert_element(obj, 0) when the array is empty is idd causing a seg fault23:16
van51but what I can't understand is how did the octave example run smoothly then23:16
van51because I used the same logic in CombinedKernel as well23:17
@sonney2kvan51, no idea - write a unit test and fix this insert_element to work in all reasonable cases23:20
van51okie23:21
@sonney2kdvalcarce, I will move it over then23:29
van51sonney2k: actually, valgind reports it as an invalid memory read23:29
van51but there is no seg fault23:29
@sonney2kvan51, lucky then23:29
@sonney2kdvalcarce, but not  now (too tired)23:29
van51so maybe octave is more tolerant in those situations than python?23:29
@sonney2kvan51, no we were just lucky23:30
van51how?23:30
@sonney2kwe should always check if valgrind23:30
@sonney2kwell some corruption in not too important memory23:30
@sonney2kbut no idea really23:30
@sonney2kjust relax and fix it23:31
van51hehe23:31
van51i just find it weird!23:31
dvalcarcesonney2k, ok, there is no hurry :)23:31
@sonney2kI gave up trying to understand all bugs23:31
@sonney2kalright that's it for me for today cya!23:39
