iRmantou_i complied code on win10,i did not use the appveyor because it tell me in the queue,and i do that by myself.And there are some warning like error C2143: syntax error: missing“;”(before“}”) [C:\projects\shogun\\build\tests\unit\discover_gtest_tests.vcxproj]14:12

@HeikoSlisitsyn: ++17:38
lisitsynI've recently dropped a shitload of code at my job17:38
lisitsynfeel so good17:38
@HeikoSlisitsyn: after tags is in17:38
@HeikoSwe can drop 1000+ lines17:38
lisitsyntrue17:38
@HeikoSso hackathon17:38
@HeikoSwill cut off things17:38
lisitsynno I mean dropping algorithms we don't test17:38
lisitsynor support17:38
@HeikoSlisitsyn: yes17:38
@HeikoSwell17:39
lisitsynnot only infrastructural stuff17:39
@HeikoSsome of the svm code is fast and state of the art17:39
@HeikoSand not tested, nor supported17:39
lisitsynto be really honest I'd drop neural nets :D17:39

@HeikoSlisitsyn: dont know, I think the basics should be there17:39
lisitsynkeras kills the necessity17:39
@HeikoSlisitsyn: but we can do it17:39
@HeikoSyeah true17:39
@HeikoSlets drop them17:39
@HeikoSrather work on a cool framework17:39
lisitsynno reason to use shogun for neural nets17:39
lisitsynbut17:40
lisitsyn*all* the software is about training17:40
lisitsynwe should focus on applying17:40
@HeikoSyes, I think shogun should become algorithm free at some point17:40
@HeikoSand just have some very fine standard tools as plugins17:40
@HeikoSbut yeah17:40
@HeikoSlets push in that direction at some point17:40
@HeikoSI want to use it as research code framework17:41
@HeikoSfor which currently it is shit17:41
@HeikoSyou want to use it for applying, for which currently it is shit as well17:41
lisitsynHeikoS: good news is that all the software is shit for applying17:42
@HeikoSlisitsyn: yep17:42
@HeikoSlisitsyn: sooo17:42
@HeikoSGSoC project? :D17:42
@HeikoSwe could start with being able to apply our own models17:42
@HeikoSwhich mostly doesnt work17:42
lisitsynlol17:42
@HeikoSlisitsyn: I think this is a good point17:44
@HeikoSand you acutally know what you are talking about there17:44
@HeikoSso lets do that17:45
@HeikoSgood idea17:45
@HeikoSwe can keep models as plugins17:45
lisitsynHeikoS: well managing models, managing what these models stand for17:45
lisitsynis the most painful for me now17:45
lisitsynI wouldn't say there is a good solution around17:46
lisitsynHeikoS: amalgamation is the word17:46
lisitsynI think we can go for project like that17:46
@HeikoSwhat do you mean by that?17:46
lisitsynHeikoS: check amalgamation in mxnet17:46
lisitsynthey transform model into .so file17:46
lisitsynwhich you can load and call apply()17:46
lisitsynit is superoptimized this way17:47
lisitsynthe parameters may even be *on stack*17:47
lisitsynbecause they are like17:47
lisitsynfloat w_1 = 1.0;17:47
lisitsynfloat w_2 = 4.3;17:47
@HeikoSyeah get it17:47
lisitsynand return x_1*w_1 + x_2*w_217:47
@HeikoSwell for simple models17:47
@HeikoSNNs cant be on stack17:47
@HeikoSGPs neither17:47
lisitsynHeikoS: some nns are 4-5 mb17:47
lisitsynwhy no17:47
@HeikoSSVM only the weights17:47
@HeikoSsure but not the deep conv nets17:48
@HeikoSSVM needs the data17:48
lisitsynHeikoS: it is not a matter of stack17:48
@HeikoSall kernel methods do17:48
lisitsynit is about codegen17:48
@HeikoSyeah17:48
@HeikoSI mean, lets discuss this shit17:48
@HeikoSI agree actually17:48
lisitsynwell it may be like a funny project17:48
lisitsynit is just now when I formulated it this way17:49
lisitsynbut the idea of this amalgamation stuff bothers me for a long time17:49
lisitsynHeikoS: we do that at yandex since like dark ages17:49
@HeikoSyeah, lets put it to open source17:49
lisitsynHeikoS: hmm no not sure :)17:50
lisitsynHeikoS: it is just one class of algorithm17:50
lisitsynwhich predates xgboost17:50
@HeikoSI guess we should think about what we want to offer17:51
@HeikoSand to whom17:51
@HeikoSand then decide17:51
@HeikoSwho uses the framework and for what17:51
@HeikoSshould write down use cases17:51
@HeikoSand then go from there17:51

@HeikoSOXPHOS: so another rebase? :)18:14
@HeikoSOXPHOS: what conflicted?18:15
OXPHOSHeikoS: trivial stuff. removed a method in SGVector etc. Basically there's no functional conflict at all18:16
@HeikoSok cool18:17
@HeikoSOXPHOS: btw I added a cmake thing to the TODO18:18
OXPHOSHeikoS: thx18:18
OXPHOSI guess the HAVE_LINALG_LIB can be removed as well.  Not sure whether I should open a new PR for it because I'm gonna change cmake18:18
@HeikoSyeah do a PR in the feature branch18:19
