sonne|workhey thoralf11:02
thoralfsonne|work: Seems my first patch works fine.  Now talking about the next one?11:04
sonne|workthoralf: yes sure11:04
thoralfhttps://github.com/shogun-toolbox/shogun/pull/177211:04
sonne|workI think we need DynamicRefObjectArray ...11:05
sonne|workotherwise you have the same issues again with you not knowing when to ref / unref11:05
* wiking is writing a new qp library11:12
sonne|workwiking: hurray another one :D11:13
@wikingdelibrately not making part of shogun so that ppl can use it externally11:13
@wikingbut the thing is that it'll be lgpl311:13
sonne|workwiking: libqp11:13
@wikingand will do a completely subtitute in sense of qp11:13
@wikingof mosek11:13
@wikingso finally we can do mosek like qp for structural learners11:14
@wikingsonne|work: libqp is almost good11:14
@wikingbut it's too strickt with the s.t. of the minimization11:14
@wiking*strict11:15
@wikingand another thing11:15
@wikingit's gonna have a general KKT solver using various factorization methods11:15
@wikingso if we manage to get this into shogun11:15
@wikingwe might consider to exchange the kkt solving in other qps11:16
@wikingusing these ones11:16
@wikingas they'll be superoptimized11:16
@wikingusing eigen11:16
@wikingand openmp11:16
@wikingbasically what i'm trying to implement is a quadrating cone program11:17
@wikingso it'll solve a pair of primal and dual quadratic cone programs11:18
thoralfwiking: Ehr.  Many people from my institute are developing for LP/QP/fooP-solver.  Sure you wanna start from scratch?11:18
@wikingthe idea came from CVXOPT11:18
sonne|workwiking: that is a massive effort... not sure you have the time...11:18
@wikingthoralf: ^11:18
@wikingsonne|work: well about kkt interfacing i'm sure that i dont have time for that11:19
thoralfwiking: fyi: http://www.zib.de/en/optimization/software.html11:19
@wikingi just want to give an eigen like (hpp only implementation) for KKT solving11:19
@wikingthoralf: license?11:19
@wikingor all gpl3 valid11:19
-!- shogun-notifier- [~irker@7nn.de] has quit [Quit: transmission timeout]11:19
thoralfhttp://scip.zib.de/licence.shtml11:20
thoralfOne of them (ZIBopt)11:20
@wikingthoralf: yeah it's almost like svmlight license :S11:20
thoralfwiking: If you have concerns about the license, let me talk to my boss. ;)11:21
@wikingthoralf: yeah we already have issues with svmlight :S11:21
@wikingand basicaly it's almost like mosek in one way11:21
@wikingsonne|work: hehehe remember when u told me this "sonne|work> wiking: that is a massive effort..." about cmake? :)11:21
sonne|workwiking: yes and we are still not at the stage where cmake is working without a hassle11:22
thoralflol11:22
@wikingsonne|work: sorry :S11:22
thoralfThe Gallileo gambit.11:22
@wikingfor trying my best11:22
@wiking:P11:22
@wikingthoralf: http://pystruct.github.io/index.html11:22
@wikingu know this one... ?11:22
sonne|workwiking: so just dont' underestimate the work11:23
@wikingpretty cool about ssvm11:23
@wikingsonne|work: yeah sure note11:23
@wiking*not11:23
@wikingsonne|work: but we are getting there with cmake i think11:23
@wikingthoralf: btW: big up for the separation for structuralData from sgobjc11:23
thoralfwiking: Yeah, heard of, but Python is painful when you're having huge data... :(11:24
thoralfwiking: Even thought of using it.11:24
@wikingsonne|work: if i manage to get that KKT shit working and when we get gsoc slots it could be a good idea to dedicate a student to do that kkt interfacing for other qp solvers11:24
@wikingthoralf: sure, this is why i started this whole shit ... wanna do it in c++11:24
@wikingeigen style11:24
@wikingor tapkee style11:24
lisitsyn1hah11:25
lisitsyn1tapkee style come on yo11:25
@wikinglisitsyn1: heheh yeah if u r around i have questions11:25
lisitsyn1wiking: sure11:25
-!- lisitsyn [~lisitsyn@80.252.20.67] has quit [Disconnected by services]11:25
-!- lisitsyn1 is now known as lisitsyn11:25
@wikinglisitsyn1: do u know if for example in eigen the llt solver (cholesky factorization)11:25
@wikingif i give it a sparsematrix11:26
@wikingwill it use the sparse cholesky11:26
@wikingor it will use the dense one?11:26
lisitsynwiking: don't remember by heart actually11:26
lisitsynbut I tend to think it is dense11:26
@wikingas i've tested that it works11:26
thoralfsonne|work: Well, about the DynamicRefObjectArray thing: I already spend too much time on this issue.  I did got a working patch - and did even a refactoring of CSGObject.11:26
@wikingEigen::LLT<MatrixType> lltOfK11:26
@wikingwhere MatrixType = Sparse11:26
@wikingworks as well11:26
@wikingbut dunno if it's actually calling the sparse one11:27
-!- lisitsyn1 [~lisitsyn@80.252.20.67] has joined #shogun11:27
thoralfsonne|work: To make it short: I won't do this DynamicRefObjectArray class... but I could adapt my patch if you could provide it.11:27
@wikingor just does the dense on sparse matrix11:27
-!- mode/#shogun [+o lisitsyn] by ChanServ11:27
@wikingif so11:27
-!- lisitsyn1 was kicked from #shogun by lisitsyn [lisitsyn1]11:27
@wikinghow would u do this then11:27
@wikingsay template<typename MatrixType> class KKTCholeskySolver11:27
@lisitsynwiking: there is SimplicialLLT or so11:27
@wikinglisitsyn: yeah i know11:27
@wikingbut it would depend on the MatrixType which one to use11:27
@lisitsynthat works with sparse quite ok11:27
@lisitsyndo you want it generic?11:28
@wikingyes11:28
@wikingi want it to be able to do it both on sparse and dense11:28
sonne|workwiking: you were working on cmake since june this year ... and your estimate was 2 weeks max11:28
@lisitsynwiking: well template specialization ;)11:28
@wikingsonne|work: well i've got cmake working in 2 weeks no? :))11:28
@wikinglisitsyn: ok so that's the only way right?11:28
sonne|workwiking: lol11:28
@wikingi thought so....11:28
@wikingsonne|work: well we are really now better off with this than the ./configure i'd say11:29
@lisitsynwiking: you can actually support not only eigen but any other stuff11:29
@wikingbut we can always switch back to ./configure ;PP11:29
@wikinglisitsyn: yeah i dont want :D11:29
@wikinglisitsyn: just fucking have eigen11:29
@wikingit's really easy to have installed on a toaster even :PP11:29
@lisitsynwiking: with sfinae you could check if method supports some operator() :D11:29
@lisitsynplug n play haha11:29
@wikinghahaha p'n'p11:30
@wikingwhat was that shit about in the 90s11:30
@wiking:DD11:30
@lisitsynwiking: yeah I still remember even though I was like 5 in the middle of 90s haha11:30
@wikinglisitsyn: woah http://www.boost.org/doc/libs/1_55_0/libs/utility/enable_if.html11:31
@lisitsynwiking: yeah that's easy11:31
@wikinglisitsyn: do we have something similar in stdc?11:31
@lisitsynwiking: no, I don't think yet11:31
@lisitsynwiking: I usually rewrite sfinae haha11:32
@wikinghahahah11:32
@lisitsynbecause boost slows down compilation way too much11:32
@lisitsynand my autocompletion goes slower :D11:32
@wikingyeps11:32
@wiking:D11:32
@wikingso true11:32
@wiking:>11:32
@wikingoh woah11:33
@wikinghttp://nonchalantlytyped.net/blog/2012/06/27/yet-another-sfinae/11:33
@lisitsynwiking: yes canonical sfinae11:33
@lisitsynah11:33
@wikingok so actually it's doable11:33
@lisitsynone more sfinae11:33
@lisitsyn:D11:33
@wikingyes11:34
@lisitsynwiking: well yeah if you want to check if it is sparse it is easy11:34
@wikingcool i'll do it then laater11:35
@wikingfirst i want to have it ready for initial commit that it actually works11:35
@wikingand then i'll do writing11:35
@lisitsynwiking: if you want to choose solver you'd have to have two parts11:35
@lisitsyncompile time part which selects sparse/dense11:35
@lisitsynand runtime part which selects proper solver11:35
@wikingmmmhmmm11:35
@wikingwell we'll see how far i can get with it11:35
@wikingand then if u have time for comments i'll give u a link11:36
@wikingto check on the shit11:36
@lisitsynwiking: sure11:36
@wikingoooh maaan11:37
@wikinglisitsyn: this is really daily wtf11:37
@wiking11:34 < lmatteis> i have an Microsoft Access file database11:38
@wiking11:34 < lmatteis> what's the easiest way to query it using SPARQL11:38
@wikingthe first line11:38
@wikingMicrosoft Access file database11:38
@lisitsynwiking: haha11:38
@lisitsynwiking: I actually tried another approach11:39
@lisitsynlike11:39
@lisitsyntemplate <typename MatrixType, typename SolverType>11:39
@wikingyeah i thought o fthat11:39
@wikingbut what if the idiot user (see academic 99%)11:40
@wikinggives u11:40
@wikingDenseMatrix, SparseSolver11:40
@wiking:)))11:40
@wikingof course i can do template specialization11:40
@wikingbut i dont want11:40
@lisitsynwiking: you fail compile time then11:41
@wikinglisitsyn: heheh11:42
@lisitsynwiking: it is ideal to see no <> so you could use that builder like syntax11:43
@lisitsynto approach with inference11:43
@lisitsynso you do solve(matrix).using(LLT)11:44
@lisitsynagain compile-time failure when doing something dumb11:44
@lisitsynwiking: if you want to have fun of users I have one thing I didn't implement yet11:45
