@sonney2kwiking, must have been important :D15:31
@wikingsonney2k: oh yeah i remember15:55
@wikingsonney2k: should we use DynArray<> as part of the public api or rather CDynamicArray?15:56
@wikingand what's the best way to have a DynArray< DynArray<> >15:56

@wikinganybody around18:21
@wiking?18:21
lisitsynwiking: yes18:26
@wikinglisitsyn: ok so here's the problem18:27
@wikingi have a set of sparse-like vector (that's now basically a DynArray)18:27
@wikingit's for storing indices18:27
@wikingi have like N of them18:27
@wikingi'd like to store them in an array or list18:27
@wikingand then i have to convert it to SGVector<> for being able to do add_subset()18:28
lisitsyncrazy :)18:28
@wikinghow should i store the array of DynArrays/18:28
@wiking?18:28
lisitsynand you need to serialize it, right?18:28
@wikingi've tried CDynamicArray<DynArray<index_t> >18:29
@wikingbut that doesn't work18:29
@wikingyeah it'd be great to serialize18:29
-!- van51 [~van51@ppp-94-66-12-14.home.otenet.gr] has joined #shogun18:29
lisitsynwhy doesn't it work?18:29
@wikingbtw dunno, parameters->add_vector() is complaining18:30
@wikingin CDynamicArray...18:30
lisitsynahhh18:30
@wikinganyhow18:30
lisitsynyes I guess add_vector  works only with simple types18:30
@wikingyeps18:30
@wikingmmm18:31
@wikingso yeah i have no clue18:31
@wikingof course std::vector<std:vector<index_t> > would work...18:31
@wiking:P18:31
@wikingah and the problem is that i dont know the sizeof of DynArray...18:33
lisitsynthat's basically what ya need :)18:33
-!- pickle27 [~kevin@d67-193-243-174.home3.cgocable.net] has joined #shogun18:33
@wikingi mean prior creating it18:33
@wikinghence i cannot use SGVector18:33
@wiking:P18:33
lisitsynI see no workaround for this right now18:34
@wikingbasically i'm trying to implement this: http://www.stat.berkeley.edu/~breiman/RandomForests/cc_home.htm#ooberr18:35
@wikingfor that i have to get the indicies for the elements that are out of bag for each bag...18:35
@wikinglisitsyn: btw bool* array1; bool* array2; bool* array2 |= array1; would work? :)18:52
@wikingnoup it seems not :)18:54
-!- lambday [67157f36@gateway/web/freenode/ip.103.21.127.54] has joined #shogun19:05
lisitsynwiking: what's it?19:19
@wikingnada19:25
@wikingi'll have to use some STL it seems19:26
lisitsynwiking: yeah we've got to find a way to employ stl w/o pain20:04

@sonney2kwiking, never use DynArray but rather DynamicArray/DynamicObjectArray when you want to serialize21:46
@wikingsonney2k: yeah i've figured because of sgobject...21:58
@wikingnews on the new server? :)21:59
@wikingbtw: any of u who has linux plz update integration data21:59

@sonney2kwiking, yeah it is ordered22:08
@wiking\o/22:10
-!- gsomix_ [~gsomix@109.169.254.249] has quit [Quit: Leaving]22:11
@wikingsonney2k: and how can i store an SGVector in an array?22:16
@wikingany kind of array22:16
@wikingor list22:16
@wikingas currently i dont see that happening in shogun22:16
@sonney2kwiking, well store it in a DynamicArray and good22:28
@sonney2kwiking, any clues why I am getting this?22:39
@sonney2k git push github master22:39
@sonney2kTo git@github.com:shogun-toolbox/shogun-data.git22:39
@sonney2k ! [rejected]        master -> master (non-fast-forward)22:39
@sonney2kerror: failed to push some refs to 'git@github.com:shogun-toolbox/shogun-data.git'22:39
@sonney2kohh I got got got it22:40
@sonney2kI wasn't on a branch22:40
lisitsyntypical for shogun-data22:40
lisitsyn;)22:40
@sonney2klisitsyn, :P22:41
lisitsynsonney2k: it happened to me like 10 times or so22:41
lisitsynno idea why22:41
lisitsynI don't remember what's the case it tracks off the branch22:41
-!- shogun-notifier- [~irker@7nn.de] has joined #shogun22:42
shogun-notifier-shogun-data: Soeren Sonnenburg :master * b1dee0e / testsuite/tests/ (2 files): https://github.com/shogun-toolbox/shogun-data/commit/b1dee0e05df512b4d9011414d1b14374521afdbf22:42
shogun-notifier-shogun-data: update prunevarsubmean data22:42
shogun-notifier-shogun: Soeren Sonnenburg :develop * df6c6c6 / data: https://github.com/shogun-toolbox/shogun/commit/df6c6c62bd86ba10e9a2e968881e5d5c59beb6ba22:42
shogun-notifier-shogun: require new data version22:42
@sonney2klisitsyn, maybe it looses track of the branch when one does git submodule udpate or even git pull in shogun/ ?22:43
lisitsyngit submodule update I think yes22:43
@sonney2klisitsyn, well checkout master22:44
@sonney2klisitsyn, and tehn git pull in the shogun dir22:44
@sonney2klets see if it changes things22:44
lisitsynsonney2k: do you have any insight whether something based on SO svm is applicable to frame-rate object detection?22:49
@sonney2klisitsyn, well I guess you would have to prefilter quite a bit and you could only use rather simple models22:53
lisitsynsonney2k: it seems it is time for me to apply shogun for something commercial22:54
lisitsynessentially it is just object detection so lets see how it goes22:55
@sonney2kjust do it :)22:57
lisitsynsonney2k: I have to find a solution in next 15 days :D22:58
@sonney2klisitsyn, errm tough opencv?23:22
lisitsynsonney2k: what?23:23
lisitsynthat's a task for opencv true23:23
lisitsynbut may be I can learn some svm or so23:23
