mikelingHi, in order to feee the memory in v_array, do you think it's a good idea to add a function named "Deallocate()" in v_array class?09:28
mikelingso we can free it's content and memory if we don't need it anymore09:29
mikelingwiking: ^09:31

@wiking?09:35
@wikingv_array is from c++ lib09:36
@wikingafaik09:36
mikelingwiking: I mean the v_array  in https://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/lib/JLCoverTreePoint.h#L2409:40
@wikingstd::array09:42
mikelingwiking: I haven't get the point...09:47
mikelingsorry ;(09:49
@wikingok so09:53
@wikingi dont really geat09:54
@wikingget09:54
@wikingwhy do we need to use that v_array09:54
@wikingwhat i'm saying is it'd be cool09:54
@wikingif we could throw it out09:54
@wikingand use something more standard09:54
mikelingwiking: hmm, so you mean we need to get rid of v_array and use std::array  for JLCoverTreePoint?09:58
@wikingwell if it's possible09:59
@wikingthat'd be great09:59
@wikingif it's too much of a work then leave it09:59
@wikingjust make sure that you clear the v_array09:59
mikelingok, I got it :)09:59
mikelingThank you09:59
lisitsynI wouldn't try it10:19
lisitsynI have approached JL's code a few times in my life10:19
lisitsynI never succeeded10:19
lisitsynit's a mine field10:20

@HeikoSwiking: thoughts about the cmake and gpl commit?12:03
@HeikoSlisitsyn:  ^12:03
lisitsynHeikoS: es bien12:03
lisitsynHeikoS: do we have to have shogun_gpl12:04
lisitsynbut not shogun/gpl?12:04
@HeikoSlisitsyn: could12:04
@HeikoSmy thinking was12:04
@HeikoSsrc/shogun has a certain structure12:04
@HeikoSand that is replicated in src/shogun_gpl12:04
@HeikoSi would find it weird to replicate dir structure in a subfolder12:04
@HeikoSlisitsyn: but could do as well?12:05
lisitsynmakes sense12:05
lisitsynHeikoS: although12:05
lisitsynwe could drop the structure in gpl12:05

lisitsynHeikoS: can we merge bahsic?12:06
lisitsynwhat is bashic anyway?12:06
@HeikoSlisitsyn: I wouldnt do that I think, makes things bessy12:06
@HeikoSlisitsyn: merge it12:07
lisitsynah12:07
lisitsynits merged12:07
@HeikoSlisitsyn: it is a kernel based feature selection algo, based on lamday's 2nd gsoc project12:07
@HeikoSlisitsyn: and in the latest refactoring, HSIC was removed12:07
lisitsynHeikoS: I broke something at https://github.com/shogun-toolbox/shogun/pull/367412:07
@HeikoSas BAHSIC is unavailable as well12:07
lisitsynbut12:07
lisitsyndo you get the idea?12:07
@HeikoScan re-introduce it12:07
lisitsynthe thing is12:07
@HeikoSlisitsyn: I get it, all variables are accessed via getter/setter12:07
@HeikoSI would do the PR class wise12:07
@HeikoSnot for all at once12:08
@HeikoSso we can check a bit more12:08
@HeikoSwhether e.g. get/set is a bottleneck etc12:08
lisitsynHeikoS: well it is the doable step12:08
lisitsynthat leads to tags12:08
lisitsynjust make something private and fix stuff12:08
lisitsynonce we do that we are blessed12:08
lisitsynHeikoS: I am just saying that because it is super easy task for applicants12:10
@HeikoSlisitsyn: yeah good point12:10
@HeikoSmake it entrance task12:10
@HeikoSwrite instructions12:10
lisitsynHeikoS: like the kernel thing12:10
lisitsyn:D12:10
lisitsynremember that?12:10
@HeikoSyeah, well that is more messy12:10
lisitsynthe kernel madness gsoc 201112:10
@HeikoSah yeah12:10
@HeikoSlisitsyn: so the entrance tags thing should concentrate on parameters that are not part of modelselection12:11
@HeikoSand make sure the seiralization still works12:11
lisitsynHeikoS: why?12:11
lisitsynno12:11
lisitsynwe just set them to private12:11
lisitsynthat's it12:11
@HeikoSmmh12:11
@HeikoSok12:11
lisitsynno other changes12:11
@HeikoSlisitsyn: dont we eventually want to remove them ?12:11
lisitsynHeikoS: it enforces the parameter to be accessible ONLY by set/get12:11
@HeikoSI thought class parameters will disappear completely12:12
lisitsynHeikoS: yeah but it can be drilled down to three steps12:12
lisitsyn1) private to force use *available* set/get12:12
lisitsyn2) tags under the hood of *available* set/get12:13
lisitsyn3) tags *instead* of set/get12:13
@HeikoSlisitsyn: yeah ok I see, so I agree. Make it a detailed entrance task and link a *minimal* example patch (think the one you did is maybe a bit too big?)12:13
lisitsynHeikoS: yes the w is too big12:13
@HeikoSlisitsyn: make the task, it is a great idea12:14
@HeikoSand reference it in the detox2 in the wiki12:14
@HeikoSthis way we increase chances of attracting someone who is good12:14
@HeikoSlisitsyn: send me link, I will polish after12:15
@HeikoSlisitsyn: good?12:20
lisitsynHeikoS: yeah once get some time12:21
@HeikoSlisitsyn: do it now man, otherwise it wont happen :D12:21
@HeikoSJust draft I will fill in gaps12:21
lisitsynHeikoS: yeah sure but not now :D12:22

@HeikoSlambday: make sure you check all calls of the changed method, should not be too many17:36
@lambdayHeikoS: yep.. did that.. only being used in statistical testing..17:37
@lambdayplus the unit-tests all work, valgrind says green as well17:38
@HeikoSgood thing17:40
@lambdayadded one extra unit-test for testing this feature as well.. whether the method is respecting the subsets or not..17:42
