blackburnheiko: any news?00:58
heikoblackburn, I am doing some more advanced two sample tests currently01:16
heikobased on the information about the optimal kernel for that I could get 65% with a gaussian SVM :)01:16
heikobut these things will have to run over night.01:16
heikonext thing I will try is a more sophisticated kernel01:16
heikosince that also works for two sample testing01:16
heikoso I have a benchmark01:17
heikobut going to bed now01:17
heikoso see you :)01:17
blackburnI see01:27
blackburnokay I'm off too01:27
blackburnsee you01:27

wikingmmm do we have api for doing a dot product of a dense and a sparse vector?10:31
sonne|workwiking: you mean SGSparseVector * SGVector?10:34
wikingyes10:34
wikingor for that matter SGSparseVector * SGSparseVector10:34
sonne|workunfortunately not...10:34
wikingmmm10:35
sonne|workwe have that code in CSparseFeatures10:35
wikingyes10:35
wikingi saw that10:35
sonne|work...it needs to be extracted to SGSparseVector10:35
wikingyeah10:35
wikingi'll do that10:35
wikingwill send a PR about it10:35
wikingdense_dot will be a good name for the feature there as well... right?10:36
wikinglol10:44
wikinghttp://math.nist.gov/spblas/10:44
sonne|workhmmhh last update 2006??10:46
wikingi wonder if there's other lib out there for efficient sparse calculations10:47
wikingapparently10:48
wikingMTL410:48
wikingThe Matrix Template Library version 4 is a generic C++ template library providing sparse and dense BLAS functionality. MTL4 establishes an intuitive interface (similar to MATLAB) and broad applicability thanks to Generic programming.10:48
wikingeigen seems to have something for sparse matrices10:48
sonne|workthen better use eigen10:48
sonne|worknothing hurts more than depending on some lib that gets no longer maintained10:49
wikingmmm10:50
wikinghttp://eigen.tuxfamily.org/dox/classEigen_1_1SparseMatrixBase.html#af64e012789113d938655fbb7c5f4538e10:50
wikingso it seems there is10:50
wikingthe only thing is now that we store sparse matrices differently than in eigen :)10:52
wikingbut yeah i dont care about this now10:52
wikingi'll optimize later10:52
wikingi just want to see results :)10:53
sonne|workwiking: however this needs to work even if eigen is not available so I guess extracting the function from sparse features is simplest10:53
sonne|workwiking: and if you look at dense_dot10:53
sonne|workthe function is trivial10:53
sonne|work5 lines or so10:53
wikingyeah i've did that10:56
wikingdoing tests now10:56
ptizoomhi, I had a break through, or more like a punny leap, with my perl-swig-sg activity and unslaught your git with a "pull-request", there are lots of things to tie up, help needed!12:04

sonne|workptizoom: to get you right - it is OK for you if we just start cherry picking patches right?15:22
sonne|workptizoom: you don't get credit in git logs, only some AUTHORS file later  - that is why I am asking15:23
ptizoomhi15:24
ptizoomhaaa, credits!15:24
ptizoomI am not there yet.15:24
ptizoomI was saying that my pull-request is not really appropriate to a master.15:26
sonne|workptizoom: yes I read that and it is true15:26
ptizoombut, yet I would like to be endorsed by this community!15:27
sonne|workhowever it does not hurt to add perl configure / make automagic and typemaps for perl15:27
sonne|workthe interface will be marked pre alpha or so anyways15:28
sonne|workonce some more examples work and we have no leaks we can go to beta :D15:28
ptizoomhold the horses15:29
ptizoomthere is a chain of picks to climbs, and lots of crevasses on the way.15:29
ptizoomthe stuff I started is very rough, and I let lots of noise in the files, but the whole structure is there , I guess.15:32
ptizoomand it needs more than one soul to complete...15:33
ptizoomhence trying to advert it on a branch of your shogun-toolbox/perl...15:35
ptizoomalternatively I made enough noise so you might direct other benevolence to the ptizoom/shogun/perl_swig_120924?15:36

ptizoomnote:I think it is not converging because I coked up the transfer of vector into a sv_pv memory... (sigh)15:44
sonne|workptizoom: good enough to me. I will have a look15:48
ptizoomcheck out swig_typemap.i, pdl.i15:49
ptizoomanyway,15:52
wikingeh this was a big spam :)15:53
ptizoomsorry15:53
sonne|workI will15:55
wikingsonne|work: SGVector<T>::add(SGSParseVector<T> v) ?16:03
wikingor at least we should have an SGVector(const SGSparseVector<T>& orig) copy constructor in SGVector16:04
sonne|workboth make sense!16:05
wikingor of course SGVector<T> SGSParseVector::construct_dense_vector () const; function16:05
wikinghehe yeah16:06
wikingok will extend them16:06
sonne|workjust do it :D16:06
wikingdoh16:24
wikingnote: candidate function not viable: no known conversion from 'SGSparseVector<float64_t> *' to16:24
wiking      'const SGSparseVector<double>' for 1st argument; dereference the argument with *16:24
wiking                void add(const SGSparseVector<T> x);16:24
wikingah ok my bad16:25
wikingah ok my bad16:25
