sanujwiking, i have updated this https://github.com/shogun-toolbox/shogun/pull/335707:40
@wikingcan you please explain more detail about07:41
@wikingwhat's TagRealVector and RealVector are like? and why not the same? :)07:41
sanujTagX contains a name and type information for the object X07:41
sanujso TagRealVector is an identifier for RealVector object07:42
@wikingstill dont understand07:43
@wikingcould you maybe explain it a bit differently?07:43
sanujwiking, https://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/lib/tag.h#L4207:43
sanujokay07:43
sanujlet me try07:44
sanujyou have an object of RealVector called r_vec07:44
sanujand you have another object called "obj"07:44
sanujobj has a member_variable named "numbers" which is of type RealVector07:45
sanujnow there are two ways to set the value of member_variable named "numbers" in "obj"07:45
sanujobj.setsRealVector("numbers", r_vec)07:46
@wikingwhy not: obj.sets("numbers", r_vec)07:46
@wiking?07:46
sanujbecause sets<T> is a template function07:47
sanujso in swig you need to instantiate it with different types07:47
@wikingsets is not a sets(string, Any) ?07:47
sanujwiking,07:48
sanujtemplate <typename T, typename U=void>07:48
sanujvoid sets(const std::string& name, const T& value)07:48
@wikingy07:48
@wiking?07:48
sanujwiking, well, how else can it be?07:49
@wikingsets could accept any type07:49
@wikinganyhow yes listeing07:49
@wikingso you have07:49
@wikingso you07:49
@wikingbasically07:49
@wikinggenereaate07:49
sanujyou have name of parameter that you want to set, value of parameter and type of parameter as T07:50
@wikingsets[WHATEVER THE FUCK YOU WANNA SET](string, obj)07:50
@wikingfor the swig interface?07:50
@wikingso if i want to set for an object07:50
@wikingmy new KurvaMachine07:50
@wikingthen i'll have07:50
@wikinga setsKurvaMachine("name of kurva machine instance", machine)07:50
@wiking?07:50
@wikingthis is the swig interface/07:51
@wiking?07:51
sanujwiking, no, only those params can be set which are registered in the object by using register_param()07:51
sanujin the constructor07:51
@wikingyeye07:51
@wikingbut say07:51
@wikingi have a07:51
@wikingin my object07:51
@wikingregistere07:51
@wikingso say my new class is liek07:52
@wikingclass X{ .... CKurvaMachine m_kurva_machine;};07:52
@wikingright?07:52
@wikingi mean this is the old way07:52
@wikingbut just to give you an example07:52
@wikingso in this case07:52
@wikingk = X()07:52
@wikingk.setsKurvaMachine("name", kurva_obj)07:52
@wiking?07:52
sanujyeah07:53
@wikingok07:53
@wikingi dont know if i wanna laugh or cry07:53
@wikingthis is fucking madness07:53
@wiking...07:53
@wikingbut ok07:53
sanujwiking, you can use sets() also07:53
sanujbut you need to make TagKurvaMachine("name")07:53
sanujthen07:53
sanujk.sets(tag_kurva_machine, kurva_obj)07:54
@wikingso then07:54
@wikingi'll have to have a new Tagged instance07:54
@wikingthat's nothing else07:54
@wikingjust a wrapper07:54
@wiking*ish thingy07:54
@wikinghttp://gifrific.com/wp-content/uploads/2012/08/no-words-homer-into-brush.gif07:54
sanujhaha07:54
sanujyes07:54
sanujwiking, i had discussed this with lisitsyn and HeikoS both07:55
@wikingsanuj, ok08:11
@wikingall green08:11

sanujwiking, ok so i tried k.sets("name", kurva_obj) on my local08:18
sanujand it works fine08:18
sanujbut the problems is then there won't be symmetry in sets(), gets() and has()08:19
sanujproblem*08:19
sanuji.e.08:19
sanujk.sets("name", kurva_obj) will work08:19
sanujbut k.gets("name") will not work08:20
sanujk.getsKurvaMachine("name") and k.gets(tag_kurva_machine) will work08:20

@wikingc4goldsw, how's your refactor going?13:19
c4goldswwiking: Slowly, taking my time.  I did LDA a few days ago but, when doing a unit test, the outputs are completely different for one test and the same for another.13:20
c4goldswIt's odd, but I've yet to put it through a debugger.13:20
@wikinghehehe13:21
@wikingyeah gdb/lldb is usually something that helps a lot13:21
@wikinga good friday read btw: http://arxiv.org/pdf/1602.04938v2.pdf13:21

@wikingbtw you know we have a track record of having people getting accepted to MIT :)13:23
@wikingso people contributing (gsoc or otherwise)13:24
c4goldswHahaha, I think the top tier schools are a little out of my reach.  I have a 3.65 right now, hoping to bump it up.13:24
c4goldswI'm aiming for Oxford, Cambridge, Imperial, Edinburgh, etc.13:25

lisitsyn6921 in the world rating13:45
@wiking\o/13:45
@wikingthose ratings are actually bullshit13:45
lisitsynthe best people13:45
sanujlisitsyn, why did you do masters?13:46
@wikingSaurabh7, ping?13:46
lisitsynwhy not13:46
lisitsyn:D13:46
sanujlisitsyn, i actually had a question13:46
@wikinglisitsyn, did you have an option?13:46
@wikinglisitsyn, to do it or not?13:46
lisitsyngo to army13:46
lisitsynmaybe13:46
lisitsyn:D13:46
@wikinglisitsyn, i had no option....13:47
sanujlisitsyn, oh that happens in russia13:47
sanujis it like israel?13:47
Saurabh7wiking: yo13:47
sanujlike you have to serve in the army13:47
@wikingSaurabh7, so what with knn13:47
lisitsynyou have to but you can avoid that13:47
@wiking?13:47
@wikingi took much longer than expected :)13:47
@wikingSaurabh7, but anyhow if this is green13:47
@wikingand i can dig through the code13:48
@wikingcan u look at the next task we discussed?13:48
sanujlisitsyn, i'm considering masters in US, but it's damn costly13:48
@wikingsanuj, i would *never* pay for education13:48
@wiking:)13:48
@wikingget a scholarship13:48
sanujnot good grades13:48
Saurabh7wiking: yes, I removed most external code, should be ok now13:48
sanujis there another way to get scholarship?13:48
sanujhaha13:48
Saurabh7i will send that on top of this13:49
@wikingok13:49
sanujPhD can be funded :D13:49
lisitsynoh introducing other policy to any13:49
lisitsynbroke too much13:49
sanujlisitsyn, ohkay13:49
lisitsynI am still struggling with SG_ADD13:49
lisitsynbut its close13:50
sanujlisitsyn, we have this in swig13:50
sanuj%template(TagKernel) Tag<CKernel*>;13:50
lisitsynyeah?13:50
lisitsynand?13:50
sanujlisitsyn, i have forgotten why we decided on CKernel* :D13:50
sanuji mean why the pointer13:50
lisitsynbecause we have to stick with pointers13:50
lisitsynall the typemaps are working with pointers13:50
sanujokay13:51
sanuji remember something like, i tried CKernel but it was not working13:51
sanujso moved to pointers13:51
sanujbut i don't remember exactly what13:51
lisitsynit can't be CKernel13:51
lisitsynit should be either Some<CKernel> or CKernel*13:52
lisitsynotherwise nothing is shared13:52
sanujokay13:52
sanujlisitsyn, sets("gaussian", kernel) also works instead of setsKernel("gaussian", kernel)13:53
sanuji checked it on local13:53
sanujbut this would break the symmetry in sets(), gets(), has()13:53
lisitsynyou mean type is changed?13:54
sanujwiking went crazy after i told him that our api is like setsX("name", X_obj)13:54
sanuj:D13:54
lisitsynwell that's the only way13:55
sanujso i tried sets("name", X_obj) and it also works13:55
lisitsynahhh13:55
lisitsynI get what you mean by symmetry13:55
lisitsynset/getKernel13:55
sanujlisitsyn, but gets("name") won't work unless you find a better implementation13:55
sanujyeah13:55
sanujlisitsyn, i mean, type info is saved in the Any object13:56
sanujcan't we recast it without passing the type info via getsX()?13:56
lisitsynno13:56
sanujhmmm13:56
lisitsynit could be possibly done in python13:57
lisitsynmaybe wiking's favourite js13:57
lisitsynbut no java and no c++13:57
@wiking:>13:57
sanujlisitsyn, we will have to save the type info in the map in SGObject::Self13:57
sanujbut i guess that is not desired13:57
lisitsynit is not about saving the type13:58
lisitsynyou just can't have variable return type13:58
lisitsyn<??> gets()13:58
sanujlisitsyn, c++ limits us in this way13:59
sanujhaha13:59
lisitsynwell you can stay in Any type as long as you can13:59
lisitsynit can be done13:59
lisitsynspeaking of symmetry13:59
lisitsynmay be it is ok to get a little bit asymmetrical13:59
lisitsynwe set much more often than we get13:59
sanujyeah13:59
sanuj:D14:00
sanujso shall i change it?14:00
lisitsynI don't mind14:00
lisitsynprobably it is better14:00
sanujbut then usage of TagX in sets() would be totally redundant14:00
lisitsynwhy?14:00
sanujobj.sets(tag_x, obj_x)14:01
sanujobj.sets("name_x", obj_x)14:01
sanujeveryone will use the latter one14:01
lisitsynyes14:01
sanujwho will make a Tag object14:01
lisitsynno reason except performance14:02
sanujlisitsyn, is Tag more efficient?14:02
lisitsynwell you don't compute hash14:03
sanujoh yeah14:03
sanujlisitsyn, cool, i'll keep both14:03
sanujlisitsyn, shall we do the next steps in plugins after GSoC ends?14:04
lisitsynyeah maybe14:04
sanujokay14:04
sanuji'll focus on readmes now14:04
sanujlisitsyn, one more thing14:15
sanujshall i move this:14:15
sanuj#ifdef HAVE_JINJA214:15
sanuj%include "shogun-base.i"14:15
sanuj#endif14:15
sanujfrom SGBase.i to modshogun.i?14:15
lisitsynno idea14:16
sanujbecause then14:16
sanuji can replace statements like this14:16
sanuj%template(TagRealVector) Tag<SGVector<float64_t>*>;14:16
sanujto14:16
sanuj%template(TagRealVector) Tag<RealVector*>;14:16
sanujas RealVector is defined in Library.i14:17
lisitsynok14:17
sanujbut Library.i is not visible in SGBase.i14:17
lisitsynmove it then14:17
sanujcool14:17
sanujlisitsyn, i'm moving it back to SGBase.i14:27
sanujbecause it still gives the same error14:27
