@wikinglisitsyn, ping11:34
lisitsynwiking: hey11:34
@wikinglisitsyn, ok so yesterday i was talking with HeikoS and was wondering whether the reference counting magic should happen in any or not (sgobject)11:34
@wikingwe concluded that it should be take care of any, or? :)11:35
lisitsynwiking: by shared_ptr/some/...11:35
lisitsynno?11:35
@wikingwell currently SG_REF + SG_UNREF11:35
@wikingi mean you kow that we are passing around11:35
@wikingCSGObject* in swig interfaces11:35
@wiking:)11:35
lisitsynwiking: we can switch to shared_ptr/some once we get rid of ctors11:35
@wikingi mean we can wrap it internally that's fine11:35
lisitsynwiking: remember that branch by toni?11:36
@wikinglisitsyn, put("asd", swigObject)11:36
@wikingshared_ptr doesn't work in many langs11:36
lisitsynwiking: it works but the only showstopper was ctor11:36
lisitsynwiking: it should work everywhere SG_REF works11:36
lisitsyncan't see any difference11:36
@wikingjust checking the typemaps11:37
@wikingfor sgref11:37
@wiking*shared_ptr11:37
@wikingin swig11:37
lisitsynwiking: you just call something else in SG_REF, that's it11:38
lisitsynshould suffice11:38

@wikingwuwei, hey hey :)11:50
wuweihello wiking11:50
@wikinglemme see what's happening with your lmnn patch11:51
wuweirebased just now11:51
@wikingkk11:52
wuweibtw, I'm considering the GSOC project continuous detox, there are ongoing previous PRs, how should I pick them up11:56
@wikingwuwei, which ones do you have in mind11:59
@wikingcould you paste the pr links11:59
@wikingplz11:59
wuweiI'm now thinking about the immutable CFeatures, I'd like to pick up this https://github.com/shogun-toolbox/shogun/pull/397012:05

@wikingwuwei, oh cool that sounds good13:05
@wikingalthough we should have a bit of talk before you jump into it13:05

@wikingwuwei, lemme know when is a good time for you13:14
@wikingto chat about the ideas there13:14
@wiking:)13:14
wuweiI've read that PR and the design proposed in the gist, shall we chat now?13:18
@wikingyes13:19
@wikingwe can13:19
@wiking:)13:19
@wikingbtw what timezone u r at?13:19
@wikingbeijing?13:19
wuweiutc+8, evening now13:19
@wikingkk13:20
wuweigreat13:21
@wikingso yeha the idea there is that we somehow be able to have views13:21
@wikingon features13:21
@wikingwithout actually copying the data13:22
wuweiYep, I see13:22
@wikingand of course we wanna be able to start using13:23
@wikingDotIterator13:23
@wikingas that has been merged already13:23
wuweiYes, but a question13:24
@wikinglistening :)13:24
wuweisome algorithms call get_feature_matrix on CDenseFeatures, so that they can perform WX, processing all feature vectors at a time13:25
wuweihow should we use the iterator in that case13:25
@wikingyeah unfortunately13:26
@wikingthat case we cannot do an iterator approach13:26
@wikingsame if for example you wanna do a SVD of the dense featuers13:26
@wikingetc13:26
wuweiso, do we still need to expose the underlying data13:28
@wikingwell in these cases unfortunately there's no way around13:28
@wiking:S13:28
@wikingor of course we could go with a visitor pattern... but that might be an overkill <- lisitsyn13:28
@wikingmeaning13:29
wuweiaha, might complicate the code13:29
@wikingDenseFeatures.operator(operation you wanna do over it)13:30
@sukey[https://github.com/shogun-toolbox/shogun] karlnapf pushed 2 commits:13:31
@sukeyhttps://github.com/shogun-toolbox/shogun/commit/00cdc0332b1364ac5e4bfd88bc10aa9cf78db27f13:31
@sukeyhttps://github.com/shogun-toolbox/shogun/commit/59187a7c0e022bd5dbf244bac2562c926797ee6213:31
wuweiwe would need to cover many different operations then ?13:32
@wikingwuwei, mmm the operator can follow an interface13:32
@wikingbut yeah that is currently not really a goal13:32
wuweiyeah13:32
@wikingfirst we should be able to do copy-less views13:33
@wiking:)13:33
wuweiright :)13:34
wuweilet's get back13:34

wuweiwiking, how do u see the subset stack, shall we replace it as the first step13:43
@wikingyes that's the idea13:43
@wikingthat once we have views implemented13:43
@wikingwe can drop substack13:44
@wikingi mean subset stack13:44
wuweiyeah sure13:44
wuweiso we should implement view first, could you suggest some initial tasks?13:47

wuwei great, let me have a try14:01
