@HeikoSwiki12:41
@wikingmilestone12:41
@HeikoSyes we have a list there12:41
@wikingwhere?12:41
@HeikoShigh level in wiki, and milestone for details12:41
@wikinglemme see12:41
@HeikoShttps://github.com/shogun-toolbox/shogun/wiki/Releases_TODO12:41
@HeikoSthis is high level12:41
@wikingtehre's no 4.2 milestone12:41
@wikingi'll create one12:41
@wikinglet's throw there issues12:41
@wikingwe wanna fix12:42
@HeikoS"what is the point of this release" " what needs to be done qualitatively"12:42
@HeikoSyep and then the issues are good12:42
@wikingbtw12:42
@wikingwhat is the next samurai on the list?12:42
@HeikoShehe12:42
@HeikoSI dont know12:42
@HeikoSI want another "powered by vodka mate and beer" :)12:42
@wikingTakechi Hanpeita12:42
@HeikoSthat was funny12:42
@HeikoSok that one is good as well :D12:43
@wiking:DDD12:43
@HeikoSdoorbell, back in 5 mins12:43
@wikingdeadline: may 2212:44
CaBaget_global_parallel().get_num_threads() already has a proper default based on the number of available CPUs. So I should assume that everything in shogun that can run in parallel also does?12:45
@HeikoSwiking: ok!12:45
@HeikoSwiking: Ill edit the wiki, you do the issues?12:46
@wikingi'm putting the issues into the milestone12:46
@wikingCaBa: yep12:46
@wikingfuck we have a lot of issues :)12:54
@HeikoSwiking: I wrote the release text12:54
@HeikoShttps://github.com/shogun-toolbox/shogun/wiki/Releases_TODO12:54
CaBadoes shogun provide anything to include subsampling during model selection? i have ~50k observations from which i would like to use only a random subset for model selection. i could of course do the subsampling myself prior to the model selection, but maybe there is a smart solution for that already in shogun12:54
CaBa?12:54
@HeikoSCaBa: The best is to just sub-sample the data yourself before you do the model selection12:55
@HeikoSthat is trivial12:55
@HeikoSMight be interesting to implement such a scheme12:55
@HeikoSYou could do that :)12:55
@HeikoSJust adding a "subset" to the features should do it btw12:55
@HeikoSi.e. 1 line of code12:55
@HeikoSwiking: the list is quite ambitious12:56
@HeikoSlike "use external library for reading files"12:56
@HeikoSbut ok12:57
@HeikoSI think top priority should go to fixing the builds and the BSD conversion12:57
CaBasure. i was thinking maybe there is some fancyness available such that model selection uses a different subset at every iteration or so. but maybe that doesn't even make sense...12:57
@HeikoSif we have those two, we already have a minimal release, the rest would be good though12:57
@HeikoSCaBa: I see what you mean12:57
@HeikoSyeah would be good to have12:57
@HeikoSone can also often stop early12:57
@wikingHeikoS: i'm adding issues that i wanna somehow sort out in this12:58
@wikingrelease12:58
@HeikoSin the sense that you did some very corse -xvalidation, and it is already clear the the parameter was shit, so one can stop12:58
@wikingsometimes the issue is irrelevant anymore12:58
@HeikoSI always wanted to do that, but currently no time12:58
@wikingjust to slim down the issues list12:58
@HeikoSCaBa: If you want to get involved, very welcome12:58
@HeikoSwiking: yeah good point12:58
@HeikoSwiking: any news back from your law collegues about the git history?12:58
@wikingah yeah i'll ping again12:59
@wikingas since then no news12:59
@HeikoSok12:59
@HeikoSwiking: the two options were: history GPL is ok, and we  have to put the GPL code into GPL repo and done13:00
@HeikoSor history matters, so we have to start a "new" BSD repo13:00
@HeikoSright?13:00
@HeikoSwiking: any news on website?13:00
lstsnwebsite on my side13:01
CaBahm. sounds like a relatively common problem, isn't there anything out there about relicensing and version control systems?13:01
lstsnmy side is sloow13:01
@wikingHeikoS: dont ask me :)))) lstsn ping13:02
lstsnyeaz13:02
@wikingok HeikoS there are now 17 open issues13:02
@wikingsome of them just needs a simple confirmation whether it is still true or not13:03
@wiking:)13:03
@wikingif anybody has some urgent wishes for 4.2 then add it13:03
@wikingotherwise let's try to close + release13:03
@HeikoSok will go over some13:05
@HeikoSlstsn: is this why you are missing letters?13:06
@HeikoSCaBa: tricky to cold turkery the GPL13:06
lstsnHeikoS: mn rsns13:06
@HeikoSlstsn: what?13:06
lstsnmany reasons!13:06
@HeikoSlstsn: whats the state on the site then?13:20
lstsnHeikoS: its quite near but I am short on time13:23
@HeikoSlstsn: whats missing?13:27
CaBawhat parallelization strategy does shogun follow during model selection? are e.g. LibSVM lauches within each job still parallelized but with a lower number of threads?13:36
lstsnHeikoS: I just need to set it up13:44
@HeikoSCaBa: it is not parallelised at the moment14:00
@HeikoSCaBa: I suggest the following:14:00
@HeikoSyou do the parameter sweeps yourself, and use shogun to do the x-validation14:00
@HeikoSthen each script/job is completely independent14:01
CaBax-validation is also not parallelized?14:01
@HeikoSCaBa: nope14:01
@HeikoSCaBa: this would require to spawn multiple objects in memory, which is why we shyed away from it a while ago14:01
@HeikoSbut it should be there you are right14:01
@HeikoSmanpower14:02
CaBahm i see14:02
@HeikoSCaBa: but as I said, just create a script that x-validates one parameter configuarion14:03
@HeikoSand then start that script multiple times14:03
@HeikoSeasy to do14:03
@HeikoS(as a workaround)14:03
@HeikoSCaBa: again, we would welcome a patch on that a lot!14:04
CaBa:)14:05
