-!- pluskid [~pluskid@li400-235.members.linode.com] has joined #shogun09:37
n4nd0sonne|work: how do you suggest me to enable compilation with mosek in shogun?09:37
n4nd0sonne|work: doing something similar to what is done for cplex?09:37
sonne|workn4nd0: yes09:42
sonne|workwhen mosek is found we enable the code using it09:42
n4nd0ook, I will dive into the configure script then09:43
sonne|workn4nd0: well more important09:44
sonne|workfigure out a way to detect that mosek is installed...09:44
sonne|workand what the compile/linkflags are09:44
n4nd0sonne|work: yes, I already found out that when I compiled some of mosek examples to try it out09:45
n4nd0for the first I do whereis mosek09:46
n4nd0and the flags I have to do -I platform/linux32x86/h/ -L platform/linux32x86/bin/ -lmosek -pthread -lc -ldl -lm09:46
n4nd0where platform/ is a subdirectory inside mosek installation path09:47
sonne|workn4nd0: but how did you find out these flags?09:50
sonne|workthese might be different for other archs09:50
n4nd0sonne|work: those in particular where the ones I used09:51
n4nd0for another archs it looks like $mosek_path/platform/$arch_dependent_dir/h09:51
sonne|workn4nd0: yeah the problem is how to figure out all these10:11
n4nd0sonne|work: I am finding my way so far - for the moment I am interested in make it work in my machine, once I do a PR we can make it more robust for other platforms10:18
sonne|workn4nd0: well you can do the PR w/o touching configure, just make sure you ifdef your class10:19
sonne|workI don't have access to mosek so I cannot test it10:19
sonne|workand not test will be run for this proprietary stuff anyways10:20
n4nd0sonne|work: I am doing it touching the configure in order to prepare the compilation flags10:21
n4nd0sonne|work: how can I do it otherwise?10:21
sonne|workn4nd0: manually add it to .config-local or .config10:22
n4nd0sonne|work: ok, I am checking, thanks!10:24

n4nd0hey blackburn15:12
blackburnhey15:14
n4nd0I've passed my software engineering exam :) awesome15:17
n4nd0blackburn: do you know if there are problems with swig a function pointers?15:17
sonne|workn4nd0: why do you need them?15:18
n4nd0sonne|work: it is the part that I will change, in CStructuredModel15:18
n4nd0the argmax, the combined feature function and the delta loss15:18
n4nd0they are with function pointers right now, but you told me to change them15:19
sonne|workn4nd0: it certainly makes directors impossible15:19
sonne|workyes15:19
n4nd0all right ...15:19
sonne|workclasses are much prefered15:19
n4nd0then I think I'll have to change it to classes now15:19
n4nd0I wanted to do it once CPrimalMosek was ready15:20
blackburnn4nd0: cool!15:21
n4nd0sonne|work: but still, just curious, is it normal that swig breaks with it?15:23
sonne|workn4nd0: I dont' know15:24
sonne|workI thought it can somehow deal with function ptrs15:24
sonne|workin the worst case %ignore them15:24
blackburnI prefer no pointers in interface15:24
sonne|workn4nd0: http://www.swig.org/Doc1.3/SWIG.html#SWIG_nn3015:24
sonne|workit is possible15:24
sonne|workbut I prefer clean interfaces too15:25
n4nd0yeah, I understand15:25
sonne|workalright guys15:34
sonne|workit is time for me to be away for some time...15:34
sonne|workI will be in chat from time to time15:34
sonne|workbut no promises :)15:35
n4nd0sonne|work: enjoy your holidays!15:36

pluskidhuuuuuuuge good news! :D15:38
n4nd0where's wiking? he would support us too15:38
blackburnat pakdd15:38
pluskidbtw: blackburn, the Vowpal Wabbit in shogun is a wrapper of the official VW, right?15:39
blackburnyes but VW was updated pretty much15:39
blackburnafter GSoC 201115:39
pluskidhmm...15:39
blackburnnot a wrapper even15:40
blackburnjust integrated code15:40
pluskidI saw there's even a specific type of features for vw15:40
pluskidStreamingVwFeatures15:41
pluskidis there any other online machine in shogun other than VW?15:41
blackburnwell larank should support that15:42
blackburnbut not integrated for streaming features15:42
pluskidOK, I'll first try to use the current Shogun VW for conditional probability tree15:42
blackburnwhy online?15:42
pluskidbecause CPT is an online algorithm15:42
blackburnhuh15:43
blackburncool15:43
pluskidit's from JL :D15:43
pluskidit seems JL loves online15:43
pluskidbut there are some problems15:43
pluskidI'm not sure15:43
pluskidfor example, in shogun how do you specify Labels for an online algorithm15:44
blackburnin features IIRC15:45
pluskidyou mean embed labels in features?15:45
blackburnyes, check methods of streamingfeatures15:45
pluskidah, OK, cool15:46
blackburndaaaaaamn I broke caps lock16:20
n4nd0:O16:22
n4nd0your fingers are strong16:22
blackburntried to clean it up16:24
blackburnargh16:24
