sonne|workpong pong!10:52
samuelmzsonne|work, Hi :)10:53
samuelmzsonne|work, I'm a Brazilian final year undergraduating CS student and I'm interested in working on shogun for gsoc10:53
@besser82samuelmz, Which project, esp. ?10:54
samuelmzsonne|work, specifically on the project A Meta-Language for Shogun examples10:54
sonne|worksamuelmz: nothing wrong with that :)10:54
samuelmzsonne|work, have you already found a student for that?10:54
@besser82samuelmz, cool  :D  Not yet, afaik....10:55
samuelmzsonne|work, you can find my CV here10:56
samuelmzsonne|work, https://docs.google.com/file/d/0ByjN10__oKejY2dqbXhPTmRPRm8/edit10:56
sonne|worksamuelmz: wait wait this is not how it works :)10:57
samuelmzsonne|work, I also have experience with compilers, I've used JFlex + CUP to write a compiler for the Compiler classes I had :)10:57
sonne|worksamuelmz: you need to a) submit a proposal by end of tomorrow to google melange10:57
@wikingsamuelmz: http://shogun-toolbox.org/page/Events/gsoc2014_how_apply10:57
sonne|workb) show us that you are the right man for this by already submitting a few patches10:58
sonne|worketc10:58
@wikingsamuelmz: plz read the manual ...10:58
samuelmzsonne|work, Ok, I know, I just would like to know if you think a have the correct backgroud10:58
sonne|worksamuelmz: yeah what wiking said10:58
@wikingsamuelmz: read the manual10:58
samuelmzsonne|work, I have participated of GSoC the 2 last years10:58
sonne|worksamuelmz: it might not be that difficult even - it might be that simple jinja2 templates could work out10:58
@wikingsamuelmz: it has the answer for this question10:58
sonne|worksamuelmz: which orgs?10:59
samuelmzsonne|work, successfully at Apache10:59
@wikingsamuelmz: "pplicability - “Am I good enough to do this?”10:59
@wikingIf your answer to this question is “YES!”, then you are the right person ;) "10:59
@wikingsamuelmz: which apache project?10:59
sonne|worksamuelmz: and the other?10:59
samuelmzsonne|work, Apache Xalan C/C++ and Apache Xalan Java10:59
@wikingsamuelmz: but as said earlier there's no 'am i good enough' there's only your proposal + your entrance tasks solutions10:59
@wikingthat's the only thing we consider when we choose students11:00
@wikingand it's more biased by the solutions you've given for the entrance tasks11:00
samuelmzsonne|work, wiking, so I have to prepare a proposal and solve any entrance task, right?11:01
@wikingsamuelmz: so just write your proposal asap that people can still comment on it, so that you can still apply some changes11:01
@wikingand then start working on entrance tasks11:01
@wikingsamuelmz: http://shogun-toolbox.org/page/Events/gsoc2014_how_apply11:02
@wikinghas all the answers11:02
samuelmzwiking, Ok, I'm gonna be back soon with a draft of my proposal11:02
@wikinggood make sure that you send it right away in melange11:02
samuelmzwiking, Ok, cya11:03

@wikingkprah: yeah i've already commented11:44
kprahwiking: okay. Can we discuss it now?11:47
@wikingkprah: which part?11:48
@wikingkprah: i mean i don't really see how i could help.11:48
kprahThe design basically.11:48
@wikingkprah: basically i don't know how much you are familiar with OOP11:48
-!- srichakradhar_ [73f832e6@gateway/web/freenode/ip.115.248.50.230] has joined #shogun11:49
@wikingbecause from this PR11:50
@wikingi have the impression that you are not so much familiar of object oriented design patterns11:50
kprahI know the basic concepts like inheritance and abstraction but not with advanced concepts such as MVC architecture etc.11:50
@wikingmy concerns that i have is actually really basic OO design pattern11:51
@wikinge.g. always try to model entities with with classes not functions11:52
kprahSo the behaviour should be defined separately?11:56
kprahwiking?11:57

@wikingyes12:19
@wikingyou know that the application deadline for GSoC is tomorrow12:19
@wikingso in the meanwhile you should put together a proposal12:19
@wikingwerent you saying that you'd be interested in other ideas as well? http://shogun-toolbox.org/page/Events/gsoc2014_ideas12:20
kprahWell I'm not. That's the point. I need a bit of guidance here.12:21
-!- zxtx [~zv@c-50-174-221-71.hsd1.ca.comcast.net] has joined #shogun12:22
@wikingkprah: how's your proposal doing?12:22
kprahI am working on the draft.12:23
@wikingkprah: when do you think it'll be ready?12:23
kprahThe rough draft? In two hours I think.12:23
@wikingkprah: as you'll have another couple of weeks (till the 6th of april) to work on some entrance tasks to see how you do with coding...12:25
@wikingbut not for the proposal12:25
@wikingso i guess the only thing you can do now is try to concentrate on the proposal12:25
kprahOkay. I agree with you. But you won't consider my proposal without any merged code?12:27
kprahwiking?12:27
@wikingbut the problem is that i have a slight different point of view on how much guidance you would actually need12:27
@wikingkprah: well the decision of the proposals will be made latest on the 6th of april12:28
@wikingso you have some extra time to try to get some entrance tasks solved12:28
@wikingbut yes in that sense you are right that if even till the 6th of april you won't have a code that can be merged, then i'm afraid your proposal will not be considered...12:29
kprahOkay. Guess I will work on it then. by the way, can you please give a few examples here and there in my code, so that I know where I am going wrong?12:30
kprahwiking?12:30
@wikingkprah: well i gave you examples12:32
@wikingdo not model functions with classe12:32

nikolisgalHello guys I am having some trouble in configuring  and seting up shogun I am a newbiew  so anyone willing to help plz message me12:58
sonne|worknikolisgal: just ask here12:58
sonne|workor on the mailinglist12:58
nikolisgalwell i did I will re type my question12:59
nikolisgalso i have succesfully imported shogun in my eclipse ide but I seem to geting this error DescriptionResourcePathLocationType13:01
nikolisgal‘CLanczosEigenSolver’ was not declared in this scopeLogDetEstimator.cpp/shogun/src/shogun/mathematics/linalg/ratapprox/logdetline 55C/C++ Problem13:01
lwalklingHi everybody, particularly @besser82.13:01
lwalklingCan you give any advice on the usage of Fedora (20) for the development of Shogun? Would it be advisable to use a VM with Debian?13:01
nikolisgalalthough i never change anything in the code does this suppose to happen or I am missing something like configuration step or library instalation13:02
@besser82lwalkling, just a few minutes... will answer any question then  ;)13:03
sonne|worknikolisgal: sorry I use vim here...13:08
sonne|worknikolisgal: I know HeikoS uses it with eclipse but I think he doesn't compile with eclipse but just make13:09
nikolisgali did compile it with just make as well seem to geting the same error13:11
@besser82lwalkling, developing shogun on F20 is quite easy, no need for debian VM  ;)13:11
nikolisgalcould it be that i am missing some libarry or something cause i check the includes and the header files and everything seems ok13:11
@besser82lwalkling, you're from Germany?13:12
lwalklingyes, I am from Germany13:13
lwalklingI was using CMake, first I didn't follow the documentation, only when I ran into issues13:13
@wikinglwalkling: should start with the documentation13:16
lwalklingI followed the README_cmake.md, as far as I understood it13:17
@wikinglwalkling: start from README.md13:18
@wikinghave all the references u need13:18

vpericNow if only I didn't need to fiddle manually with cmake to start using python3... :)18:54
kislaysonney2k,  Hi :)18:56
@wikingvperic: you dont need to19:02
@wikingvperic: there's like 2 good examples how you can do it19:03
@wikingsee the corresponding travis build or the buildbot build19:03
kislayhi wiking , few things to ask ! if you could spare some moments...19:04
@wikingkislay: email19:05
kislaysure!!19:05
@wikingi mean mailing list19:05
kislayyup, understood.19:05
vpericwiking: ok, never saw this --find-links argument for pip before19:06
@wikingvperic: that's just for19:06
@wikingbinary packages19:06
@wikingu can run it w/o those19:06
vpericanyway, I managed, my issue is that I have a bunch of installations of python around, including both 2 and 3 in various versions, and cmake was just detecting the wrong one19:06
@wikingwe just need those to speed up the installation process in travis19:06
@wikingvperic: there's like a manual for this19:07
vpericok, but then how do you tell it to use python or python3?19:07
@wikingRTFM19:07
@wikingvperic: https://github.com/shogun-toolbox/shogun/blob/develop/doc/md/README_cmake.md19:07
vpericwiking: thanks,  I did read it and I did just what was written, I was just saying that it was fiddly19:08
@wikingvperic: well dont wonder if you have both python 2 and 3 lying around in the system that you have to fiddle with the configure system...19:11
vpericfair point19:12

vpericFor some reason, when I "git diff", the data submodule shows as "-dirty"... I've never used submodules before, what's the problem here?21:00
thoralfvperic: Happens here - I'm ignoring this. ;)21:02
thoralfvperic: Do a "cd data && git status" - what does it show?21:03
vpericthoralf: there's an untracked .tmp file under toy/21:03
vpericand yeah, removing that makes it go away21:04
thoralfvperic: Probably a unit test (maybe from me ;))21:04
vpericnah, it's an autogenerated file when I opened it in some viewer or other21:04
thoralfvperic: do a "grep -ri light-labels.tmp tests" and then a "git blame" on the found file.21:05
thoralfvperic: If you find my name, I introduced this short time ago...21:05
vpericthoralf: I dunno, I did "cd data", "git clean -f" and now everything is fine21:08
thoralfvperic: if you recursively on tests, you should find the test whcih caused this.21:08
thoralfif you grep21:09
vpericthoralf: seems to be examples/undocumented/libshogun/streaming_onlineliblinear_sparse.cpp21:14

vpericthoralf: erm, sure -- what kind of fix would you like?21:21
thoralfvperic: Well, removing the example is no fix. ;)21:22

vpericSaw his name on the list of older GSoC mentors -- his student is also a PhD student now, I've seen him around.21:28
lisitsyn1vperic: cool21:28
vpericone of them is going to turn out to be you, right?21:28
vperic:P21:28
lisitsyn1vperic: no no21:29
vpericphew :)21:29

vpericSmall world, who knew :)21:34
lisitsyn1hah21:35
lisitsyn1yeah sure21:35
vpericIs there a way to run just a particular test/example ?21:37
lisitsyn1yeah21:37
lisitsyn1you can filter tests21:37
lisitsyn1--gtest-filter=(mask)21:37
vpericok, gotta step back: how do you run tests? so far I did jsut "make test"21:38
lisitsyn1you can go to the build folder and there will be some binary executable file21:38
lisitsyn1shogun/build/tests/unit$ ./shogun-unit-test --gtest-filter21:39
lisitsyn1like that21:39

-!- Achin_ is now known as Guest1892122:13
Guest18921Shout out to any of the shogun devs here?22:13
lisitsyn1shogun veteran here :D Guest1892122:14
thoralfGuest18921: Doing the night watch here.  How can we help? :)22:16
Guest18921Awesome, hi! I wanted to make acquaintance and probe a bit about applying for some of the GSoC 2014 projects22:16
Guest18921Specifically, I'm a graduate student at the University of Michigan, and have been working on Deep Learning for some time, so Im interested in the Deep Learning Modeule proposed22:17
lisitsyn1Guest18921: for sure you are welcome to apply22:18
lisitsyn1what you should do (probably asap)22:18
lisitsyn11) contact the mentor22:18
lisitsyn12) write the proposal before the deadline (less than a day left)22:18
lisitsyn13) try to resolve some 'entrance' task (see github)22:19
Guest18921Ok, thanks, yeah I havent contacted the mentor although im working on the proposal22:20
Guest18921I went through the writeups you guys had, and saw that you guys strongly encouraged submitting a patch. Im quite familiar with github, but was wondering whether getting in a patch over the weekend would be a feasible timeline for my application to be given due consideration?22:20
lisitsyn1Guest18921: mention that you are working on some issue22:21
thoralfGuest18921: Well, the patch doesn't need to solve complicated stuff.  It's used to prove that you can handle c++.22:21
lisitsyn1and then just get your hands dirty after the deadline22:21
lisitsyn1this is ok if you do that after the deadline22:22
-!- mihaip [~mihaip@79.113.225.125] has joined #shogun22:22
lisitsyn1but the sooner the better22:22
Guest18921Ok, I totally get that22:22
lisitsyn1thoralf: mind having a brainstorm on issues?22:23
lisitsyn1we need more small issues22:23
lisitsyn1:D22:23
Guest18921What about the appiication itself. How detailed do you think the implementation specifics should be? While I'm familiar with deep learning, I still need to get familiar with the shogun codebase to see how I could integrate into the existing modules. Should my description of implementation be a plan with respect to what and when, or also how using the shogun library?22:24
lisitsyn1Guest18921: have you seen we have some template?22:25
lisitsyn1for the application22:27
Guest18921Yeah, it asks for a prelim schedule, i was just wondering how detailed that had to be22:28
lisitsyn1ahh22:28
lisitsyn1okay well22:28
lisitsyn1week 1 - week 2: get acknowledge with blabla22:28
lisitsyn1week 3: write a prototype for RBM22:29
lisitsyn1or whatever22:29
Guest18921ok cool, that gives me an idea22:32
-!- zxtx [~zv@c-50-174-221-71.hsd1.ca.comcast.net] has joined #shogun22:33
thoralflisitsyn1: Okay, you want to brainstorm.  Let's do it dirty.22:37
lisitsyn1haha22:37
lisitsyn1thoralf: lets pick a class22:38
lisitsyn1and find its drawbacks22:38
pfm_as a non-gsoc non-developer random user i'd love to see someone making more documentation for shogun22:38
pfm_or possibly i can't find it22:39
lisitsyn1pfm_: good idea22:39
lisitsyn1pfm_: any particular example of lacking doc?22:39
vpericlisitsyn1: btw, thanks a lot for mentioning the application template - I spent a long time thinking about how to structure the document, never occured to me to check on Melange.22:39
lisitsyn1vperic: oh good to hear that22:39
thoralflisitsyn1: lol, great approach.  Let me check.22:39
vpericlisitsyn1: Some doc ideas: the exact dependencies, how to run tests, the fact that python3 is supported (no, it's not obvious)... there's a whole lot that can be improved about that part of the documentation22:40
pfm_lisitsyn1: right now i'm doing cross-validation, and the only thing i can find is the notebook which mentions it, but is far from exhaustive22:40
lisitsyn1pfm_: would a notebook on xval help/22:41
lisitsyn1?22:41
pfm_there is one, which is great22:41
lisitsyn1ah sorry22:41
pfm_but for example, it shows how you can get the mean accuracy from your xval22:41
lisitsyn1okay hmmm22:41
pfm_but in order to find out the other attributes of that object i just had to check them myself in python22:41
pfm_the notebooks are great for worked examples doing specific things, but i'd like to see something more along the lines of 'here is everythign you can do with this object/function'22:42
pfm_more along the lines of normal python documentation, i guess?22:42
pfm_basically shogun seems to have a lot of functionality, but i am currently a bit limited to things which are in the notebooks22:43
lisitsyn1pfm_: sorry I don't get that thing about everything you can do22:45
lisitsyn1http://shogun-toolbox.org/doc/en/latest/classshogun_1_1CCrossValidation.html22:45
lisitsyn1pfm_: ^ isn't that you mean?22:45
pfm_lisitsyn1: yes, except i find that very difficult to read :p22:48
lisitsyn1pfm_: yeah I understand that22:48
pfm_as an example, the xval notebook mentions CrossValidationResult, and i'm not sure what that actually is22:48
pfm_and i couldn't find it by searching in that doc database22:49
vpericpfm_: if you are using IPython it's all there22:50
vperic(as far as I can see)22:50

pfm_vperic: hm, what do you mean?22:51
vpericpfm_: Perhaps I understood you, but if you are using IPython, a simple help(CrossValidationResult) shows you all the documentation for the given class.22:53
vpericmisunderstood*22:53
thoralflisitsyn1: Okay, about brainstorming.  The problem is that we miss proper documentation.22:54
vpericwhich I consider "normal Python documentation"22:54
lisitsyn1thoralf: yeah22:54
thoralflisitsyn1: If a new user wants to quickly evaluate shogun for a problem he has, it's not clear where to start.22:54
lisitsyn1we need to delegate that to students22:54
lisitsyn1:D22:54
pfm_vperic: ah i see, i am kinda new to ipython, didn't know about that22:54
lisitsyn1okay so I have an issue22:54
lisitsyn1Explain and resolve any documentation drawback22:55
lisitsyn1:D22:55
vpericpfm_: tab completion also normally works, I find it very useful22:55
pfm_how nice22:55
pfm_the result from this is similarly dense though :p22:56

pfm_i suppose what i am looking for is something like a notebook which is focused on a specific feature rather than a goal22:58
shogun-buildbot_build #234 of debian wheezy - memcheck is complete: Failure [failed memory check]  Build details are at http://buildbot.shogun-toolbox.org/builders/debian%20wheezy%20-%20memcheck/builds/234  blamelist: tklein23 <tklein23@users.noreply.github.com>, Thoralf Klein <thoralf@fischlustig.de>22:58
pfm_that is, instead of 'digit recognition', it woudl be 'exploring the options for SVMs'22:58
pfm_i am speaking in an entirely selfish wy here - i just want someoen to tell me how to get what i want, but i guess other users would feel similarly22:59
vpericpfm_: This is actually something I would be doing if I get accepted to GSoC.22:59
vpericAnd perhaps even if I don't.23:00
pfm_vperic: ok, you get my vote (i don't think i get a vote)23:00
vpericno, but I'd be happy to hear some concrete ideas/requirements, so I could potentially add them to my application23:00
vperic(sorry, my internet died for a bit there, maybe you did and I just missed it)23:02
pfm_well, i'm not in any position to be setting requirements :p i'm just a user23:03
pfm_example right now: the notebook suggests MulticlassAccuracy as a performance measure, but i'm more interested in other scores (like false negative rate etc.), and i'm not sure what those would be called23:03

lisitsyn1cool23:16
thoralflisitsyn1: I'm not sure if we're simply duplicating the notebooks, but for me the notebooks are usually nice to look at, but not a big help.23:16
thoralflisitsyn1: What do you think?  Can we improve that or are this simple to different things?23:16
thoralfs/simple/simply/23:17
lisitsyn1thoralf: yeah notebooks are great but they don't cover all the needed details23:17
thoralflisitsyn1: And what are your brainstormed entrance tasks?23:19

lisitsyn1what kind of tutorial thne?23:21
kislay_umm.. I made a notebook regarding dimensional reduction using PCA. http://nbviewer.ipython.org/gist/kislayabhi/9431770 :)23:22
thoralfkislay_: Cool!23:23
thoralfkislay_: This one looks great.23:23
kislay_yup, took me sometime :)23:24
thoralfkislay_: Looks like it took a lot time, man.23:24
vperickislay: nice word, I saw it also. Actually, just how long did it take you? :)23:25
kislay_10 days approx...23:25
kislay_had 3 iterations with Heikos :)23:25
thoralfYeah, Heiko knows how to torture people.23:26
kislay_He is a great man. He checked each and evry whitespaces. Pheww..23:26
kislay_Finally merged though :D23:26
thoralfYeah, I know.  I used to merge stuff because of bugfixes, he tried to push me into things that were not related.23:27
thoralfI did half of them, so we both were happy.23:27
thoralf:D23:27
kislay_haha :D :D23:27
vperichm, which profile do we use for ipython notebooks?23:29

kislay_vperic, pylab is imported if we specify it at the command line when initiating the server23:31

vpericthanks23:32
kislay_vperic, np!!23:33
* vperic ponders.23:33
vpericAnd of course, all Notebooks are in Py2 and I'm working on Py3. Yay.23:33
kislay_vperic, why you use Python 3. It feels like python 2 is more accepted at most places23:36
vperickislay: I dunno, I feel like it's time to move on. For our uses, they are basically the same, so it's just inertia holding us at py2.23:37
vpericYes, I agree that the transition should have been handled better, but it's too late for that now.23:37
