n4nd0heiko: good night, a bit late though :S00:12
blackburnhah! I managed to introduce some group theory in thesis00:13
n4nd0group theory?00:17
blackburnyes :D00:18
blackburncyclic group of gradient operators00:18
n4nd0I think I had never heard about group theory before00:19
blackburnreally?00:19
n4nd0really00:20
blackburnheh funny00:20
n4nd0take a look at this00:33
n4nd0http://snipt.org/vaaO800:33
n4nd0at the messages with SG_PRINT in particular00:33
n4nd0I don't really like the idea of printing these messages everywhere, it makes the code kind of unreadable00:33
n4nd0but they make the checks everywhere in MOSEK examples00:34
n4nd0blackburn: what do you think?00:34
blackburnwho did that?00:34
n4nd0that code is mine00:34
blackburnwell having informative messages is cool00:35
n4nd0I don't really like to have them everywhere in the code00:35
blackburnwhat is alternative?00:37
n4nd0I was looking for some cool idea of yours :D00:38
blackburnmacro?00:38
blackburnREQUIRE(condition, message)00:39
n4nd0pse I don't know, maybe00:39
blackburne.g.00:39
n4nd0looks better than what I do now to tell the truth00:39
blackburnREQUIRE(mosek->get_rescode()==MSK_RES_OK, "Result code is not OK");00:40
n4nd0all right, I had enough for today00:51
n4nd0too tired :S00:51
n4nd0good night!00:51

heiko1yes11:53
heiko1I for some reason did not see that11:53

gsomixsonney2k, hey. how are you?18:59
@sonney2kgsomix, fine :)19:00
@sonney2kgsomix, I hope you made some big progress while I am absent :D19:00
@sonney2k...and passed all your exams of course !19:00

@sonney2kheiko1, you are the owner of shogun/statistics basically19:13
heiko1sonney2k, yes, why?19:14
@sonney2kheiko1, I am cleaning up CMath - where would you want to see entropy() / relative entropy() / fishers exact test for whatever ?19:14
heiko1Yeah these should go to statistics in my eyes19:14
heiko1and keep a wrapper in CMath but put a deprecated or so19:15
@sonney2kheiko1, where in statistics?19:15
@sonney2kI will just remove them19:15
heiko1perhaps one can split up the statistics later19:15
heiko1oh well there is only one file for the CStatistics class19:15
heiko1the stuff in the statistics folder is for the new tests19:15
heiko1But I want to merge later19:15
@sonney2kheiko1, shogun/statistics?19:17
@sonney2kahh19:17
heiko1no in math19:17
@sonney2kshogun/math/Statistics19:17
heiko1there are all the basic functions19:17
@sonney2khmmhh why is it not in shogun/statistics/Statistics.h etc?19:18
heiko1because I added the statistics folder recently (fraft)19:18
heiko1draft19:18
heiko1I want to do that19:18
@sonney2kok19:18
@sonney2kso lgamma/ tgamma etc should also go into CStatistcs right?19:19
heiko1also there is a difference between these advanced stat methods and the basic functions like mean/variance/fisher etc19:19
heiko1yes19:19
@sonney2kheiko, ok thanks - then I will put it in there19:20
heiko1sonney2k, alright!19:21

n4nd0sonney2k, gsomix: about the director classes, I think it could be a good idea to give support for the argmax function used in SO19:54
n4nd0for the other ones (delta loss, joint feature) it could be useful too19:54

n4nd0wiking: about Psi(x,y) and Psi(x,y,h), sonney2k suggested to use a implicit representation for the joint features21:45
n4nd0following the idea of COFFIN21:45
n4nd0something similar to what is done with CDotFeatures I believe21:45
@sonney2kn4nd0, agreed21:50
@sonney2kn4nd0, gsomix - the earlier/more we can use the new director stuff the better21:51
n4nd0sonney2k: I will devote time to the COFFIN issue once I have tested and debugged the current implementation with multiclass classification21:51
@sonney2kn4nd0, sure get the beast to work first :D21:53
@sonney2kwiking, thanks for the update22:08
n4nd0can someone please help me with this error?22:08
wikingsonney2k: no worries22:08
n4nd0../../shogun/mathematics/Mosek.h:66: Error: Syntax error in input(3).22:08

@sonney2kwiking, and for the future - please send us incremental pull requests22:09
wikingother than that i'm good :P22:09
wikingsonney2k: well i won't until i don't have something really useful22:09
@sonney2kno need to do full rebases then22:09
wikingsonney2k: but yeah i'll first have to do the full reforking22:09
@sonney2kwiking, well we expect everyone to succeed anyways22:09
wikingsonney2k: so that i'll be able to do a pull request one day22:10
@sonney2kso there is no reason in not submitting patches (that don't break other stuff) one by one22:10
wikingyeah sure22:10
@sonney2kwiking, I think all you need to do is git format-patch on the old clone and then apply it to the new one22:11
@sonney2kwiking, n4nd0 went through this btw22:11
@sonney2kand all other too :)22:11
wikingsonney2k: yep i was hoping for that22:11
@sonney2kothers22:11
wikingyeah i guessed :)22:11
@sonney2kn4nd0, my suggestion is to ignore the whole mosek class22:12
n4nd0sonney2k: ok, I'll try with that22:12
@sonney2kn4nd0, %ignore CMosek; is the syntax22:13
n4nd0sonney2k: do you plan that we'll include this use of Mosek in the "final" version?22:13
@sonney2kn4nd0, we can keep it but as I said almost no one can use it22:14
@sonney2kcertainly not me, not the buildbot, ...22:14
n4nd0n4nd0: yeah, we really need something to solve this QP22:14
@sonney2kn4nd0, well if there is time we can create some kind of optimizer interface that wraps the common tasks22:15
@sonney2kn4nd0, maybe this is post GSoC though...22:15
@sonney2kwe have cplex as interface too22:15
n4nd0sonney2k: Nico told me you discussed with him about it22:16
n4nd0sonney2k: do you think that will imply lot of work?22:16
n4nd0difficult?22:16
@sonney2kn4nd0, well if it is 'just' one certain variant - say general QP with linear inequality and equality constraints + box constraints - no22:17
@sonney2kbut there is lots of stuff underneath22:17
@sonney2k...hotstarts22:17
@sonney2k...type of optimizer (dual simplex, interior point,...)22:18
@sonney2k...presolver22:18
@sonney2kall that can make a huge difference in speed22:18
@sonney2kwiking, I hope you agree it is better to not have a 100MB crap data file in shogun's src code repo... so this repository recreation was really needed and worth the pain22:19
* sonney2k has ping turn around times of 3600ms - yay22:21
blackburnsonney2k: are you still at hiddensee?22:22
@sonney2kof course22:23
blackburncool22:23
@sonney2ktotally hidden in the dune22:23
