heikoblackburn, around?17:43
heikowhat you think is the best way to append features from the CFeatures interface side?17:43
heikowe talked about that a while ago, but I lsot the overview17:43
blackburnappend two or more features?17:44
heikotwo is sufficent17:44
heikoand copying is allowed (last time it wasnt)17:44
blackburnI do not really recall what was our summary17:44
heikohow would you do it then?17:44
blackburnwhat do I recall is that we didn't like creating AppendedDotFeatures and so on17:45
heikoThe problem last time was that I wanted to do it in-place17:45
heikobut not anymore17:45
heikoperhaps just add a method to CFeatures17:45
heikolike create_appended_features17:46
blackburnhmm and override it17:46
-!- sks_ [~sks@] has quit [Ping timeout: 240 seconds]17:46
blackburnmakes sense to me17:46
heikowhich takes another feature object, and copies own data and given one to a new instance17:46
heikohow many feature classes would have to implement that?17:46
heikoif I add an abstract method to CFetaures?17:46
blackburnwell all17:47
heikohow many are that?17:47
blackburndense, sparse, string17:48
heikowell Ill do that17:48
heikoIll add17:48
blackburnI love wrong layout17:48
heikoCFeatures* create_merged_copy(CFeatures* other)=0;17:48
heikohehe :)17:48
blackburnhmm no need to do it pure I think17:48
blackburnrather do it SG_NOTIMPLEMENTED17:49
heikoI know that Ill be lazy then :)17:49
blackburnI expect you add impl only to dense17:49
heikohehe :D17:50
shogun-buildbotbuild #974 of python_static is complete: Success [build successful]  Build details are at
CIA-18shogun: Sergey Lisitsyn master * rb283832 / (2 files in 2 dirs): Fixed compilation warnings -

blackburnpuffin444: hey18:20
puffin444hi blackburn18:20
blackburncould you please fix warnings in ExactInferenceMethod?
blackburnI didn't do that to not cause you any troubles with rebasing18:21
puffin444Will do18:21
CIA-18shogun: Heiko Strathmann master * rd1ee078 / (14 files in 4 dirs): Merge pull request #608 from karlnapf/master (+10 more commits...) -
heikoblackburn, sonney2k, I might have asked that before, but why do we use this unintuitive gaussian kernel parametrisation?19:13
heikoI always forget about that and assume its exp(-0.5||x-y||^2 /sigma^2)19:13
heikowhich is the standard in most literature i know19:13
@sonney2kheiko, because it saves the -0.5 * and sigma**219:16
heikoI see, makes sense, does this make such a speed difference?19:16
heikopepole should be warned about it :)19:17
@sonney2kno, but anyways too late to change19:17
@sonney2k||x-y|| is the costly part19:17
@sonney2kif dim(x) > a handful19:17
@sonney2kheiko, btw what did you want to ask about your feature merging/appending?19:18
heikoI was trying to remember what we agreed upon when we talked about that19:18
heikosonney2k, I added virtual CFeatures* create_merged_copy(CFeatures* other)19:18
heikowhich is overloaded in subclasses of CFeatures19:18
heikoand I use that for "merging" (which is not really merging but rather copying, but thats ok)19:19
@sonney2kI forgot what exactly you wanted to do19:20
@sonney2kdidn't you need some pairs of features or so?19:20
heikosonney2k, originally I wanted to append features in-place19:21
@sonney2kI forgot why CombinedFeatures won't work for you19:21
@sonney2kheiko, what for?19:21
@sonney2kfor what :D19:21
heikoThere was something why that didnt work :)19:21
heikooh, for the two-sample tests19:21
heikoWanted to make it possible to give two objects to the class19:21
heikoBut operations are much easier if there is only on internally19:21
heikoSo we agreed upon adding a convienience method19:22
heikowhich copies two objects together to one19:22
heikoand I was wonderung what the best way was19:22
heikoI think agreed with the way I did now, but wasnt sure19:22
heikoanyway - already implemented and working19:22
heikosonney2k, I have to leave now, will be back later this evening19:23
@sonney2kheiko, so combinedfeatures would work - but only when you do some extra effort19:23
heikothis new method is easiest I think19:23
@sonney2k..doing computations for each of them or so19:23
@sonney2kso now you append with copy19:24
@sonney2kbtw we have some method for that at least for dense or sparse or string feuatres19:24
heikoI need a CFeatures interface thats why combined did not work, it doesnt see them as one object19:24
heikowhats the name of it?19:24
@sonney2kin StringFeatures.h19:24
@sonney2kbtw for sparse / string this operation is cheap19:25
heikoI know19:25
@sonney2kfor Dense with matrix it is not19:25
heikowell there is copy_subset19:25
heikobut it copies vector wise19:26
@sonney2kblackburn, btw what happened to your openmp attempts and eigen?19:26
@sonney2keigen3 that is19:26
heikosonney2k, blackburn, see you later!19:26
@sonney2kheiko, cu19:28

blackburnsonney2k: openmp is postponed19:36
blackburneigen3 is to go in next few days19:36
blackburnI'd like to get GMM back19:47
@sonney2kblackburn, yes please do it :D19:47
blackburnI feel unfair to alesis dropping whole project of him19:48
blackburnit looks I would have to use these pheew dynarray etc stuff19:53
@sonney2kwell in principle dynamic object array is the way to go19:54

puffin444@sonney2k, the buildbot can dance?!20:30
@sonney2kpuffin444, only if germany beats italy tonight :D20:31
puffin444Okay lol.20:31
@sonney2kpuffin444, btw are these yours'
puffin444Yes I am fixing them. I hope to submit a pull request with scaling that will include the fix.20:32
puffin444I almost ready to submit the request.20:34
@sonney2kI am just reconfiguring the buildbot so I noticed...20:34

@sonney2kvery good21:07
@sonney2ka goal in the beginning21:07
@sonney2kno 0:0 crap21:07
blackburnhaha very good for you21:08
@sonney2kif not I have to disable the buildbot's dance command21:08
@sonney2kmaybe replace it with cry mode :P21:08
@sonney2kblackburn, this game really is much better than the one from yesterday21:22
blackburnheh probably21:22
blackburnsonney2k: I am sorry :D21:23
@sonney2kthis guy is a weapon21:23
@sonney2klook at him21:23

blackburngreat attempt22:05
blackburnbuffon is buffon22:06
@sonney2kand he was lucky too22:06
@sonney2kthe bar rescued him22:07
blackburnno, he saved it with hands22:08
-!- alexlovesdata [55b21f1e@gateway/web/freenode/ip.] has quit [Ping timeout: 245 seconds]22:15
@sonney2kblackburn, yeah but the shot was so strong that he could only lift it only a bit and it hit the bar22:17
@sonney2kthe weapon is gone22:17
blackburnyeah no more goals from italy22:19
@sonney2kthough I don't expect any from germany22:19
@sonney2ka |x-y| > 1 goal difference makes the game boring again...22:20
blackburnsonney2k: I'd say football is usually boring - ice hockey is not :)22:21
@sonney2klet me guess22:22
@sonney2krussia is usually winning?22:22
@sonney2kicehockey I mean22:22
blackburnno, I mean rather NHL22:22
blackburnmy fav club is not of winner kind (colorado avalanche)22:22
blackburnthey just do not want to play already22:26
@sonney2k2d soccer is much more exciting than 3d22:30
@sonney2koften it seems as if this shot will hit the goal22:31
@sonney2keven though it is miles away22:31

@sonney2kblackburn, isn't your TV 2d?22:32
blackburnwhat is 3d?22:32
@sonney2kmine is22:32
blackburnlike when you play it?22:33
@sonney2kreal life?22:33
@sonney2kso this dim reduction is not lossless22:33
blackburnno 2d is less exciting than 3d for me :)22:33
blackburna lot of fun kicking ball22:34
@sonney2kso its spain : italy22:35
@sonney2kas expected22:35
blackburna little more interesting now22:35
@sonney2kwell 2:1 is deserved22:35
blackburnmay be two goals in two minutes?22:35
@sonney2kbut who cares22:36
blackburnI'd like to see22:36
blackburnhaha running to center22:36
@sonney2kwhy is it not over yet?22:36
blackburn+4 mins22:36
blackburnthey have one chancemore22:37
blackburnmay be one more22:37
blackburnargh no way22:38
blackburnit is over22:38
blackburnnot that bad to see something interested in the very end :D22:39
blackburnhowever I consider this strange to play only in additional time :D22:39
@sonney2kno more pizza ;-)22:46
blackburnfiat is not a car and spaghetti is not a food :D22:46
@sonney2kI have to switch to flammkuchen22:48

blackburnI got three words here22:49
blackburnist, eine and und22:49
