@wikingUSC: mmmm compiling shogun with visual studio will take some significant amount of time to fix some code04:16
USCwiking: Which is the easiest way to use shogun?05:20
@wikingor docker05:23
USCDocker made my computer internet connection unstable, sometimes I lost wireless connection and couldn't connect back, I had to restart my computer, so I uninstalled it,05:27
USCwhich is better VMVARE linux on windows or Docker?05:27
USCI couldn't even copy paste command into Docker05:28
USCI had to write them all again and again05:28
USCis it the same with VMWare Linux?05:29
USCAnd which linux should I use?05:29

USCI'm installing vmware + ubuntu 12.04 to run shogun10:10
USCwill you help me?10:10
USCinstallation finished10:14
USCmy data file is an Excel file10:14
USChow can I run shogun under Ubuntu 12.0410:14
USCanybody alive here?10:22
USCI need help10:22
@wikingwhy 12.04?10:27
@wikingis LTS10:27
@wikingwell excel file we dont support but you could use a csv10:27
USCwiking: glad you're here10:29
USCI couldn't find the lastest image for vmware10:29
USCdo you have a link for that?10:29
@wikingmmm u could install it from scratch10:29
USCwill shogun work with 12.04?10:30
@wikingbut that's a way outdated ubuntu10:31
@wikinghence some of the cutting edge feature of shogun might not work10:31
@wikingso i really see no point why dont u use 14.0410:31
@wikingjust download the iso10:31
@wikingand boot from that and install it10:31
@wikingand since you already have boot2docker10:32
@wikingyou possibly have virtualbox10:32
@wikingso you could use that already10:32
USCbut now I'm using vmware10:32
@wikingdon't need for vmware10:32
@wikingbut yeah you use whatever fits your needs better10:32
USCI don't understand the docker,10:32
@wikingi'm just saying that if i were u i would use 14.0410:32
USCit is just a command line like cmd in windows10:32
USCI tried cgywin also10:33
USCmake -f makefile didn't work on cygwin10:33
USChow will I run shogun under linux ubuntu?10:33
USCI have downloaded the shogun toolbox under Documents10:33
@wikingusc there's a lot of manual/help about this in the documentation10:33
USCcome on, please help me about this10:34
@wikingUSC: ?10:34
USCit has been a week, and I couldn't figure it out how to run shogun10:34
@wikingwell maybe that says something or?10:34
@wikingthis is a very good explanation10:35
@wikingbut i would suggest using the latest version of shogun10:35
@wikingand not 3.1.110:35
@wikingi.e. checkout the git repository10:36
USCI downloaded the latest version10:36
USChow will I open bash command screen on linux10:36
USCwhere is it10:36

@wiking3 more days10:48
@HeikoSfernando was super motivated to do this10:48
@HeikoSwiking: we mostly need task descriptions right?10:49
@lisitsynHeikoS: heya10:49
@HeikoSwanted to do a few these days10:49
@wikingyeah i mean the whole thing is super flexible10:49
@HeikoSlisitsyn: heya10:49
@lisitsynHeikoS: need your advice ;)10:49
@HeikoSlisitsyn, wiking shall we try to do a stammtisch tonight?10:49
@HeikoSlisitsyn: shoot!10:49
@wikinghehehe i have the interview with tonight10:49
@lisitsynHeikoS: anything GP related for a bachelor student10:49
@HeikoSwiking: awesome!10:49
@HeikoSwiking: fingers crossed!10:50
@HeikoSlisitsyn: details please10:50
@lisitsynyeah lets go wiking :D10:50
@lisitsynHeikoS: some research topic10:50
@wikingHeikoS: yeah i've got super sick... fucking a/c kills me in singapore10:50
@wikingalthough it's 35 degree celsius atm10:50
@HeikoSwiking: aaah. hate ac too10:50
@wikingso helooooo bitches :D10:50
@lisitsynHeikoS: need any problem that could be solved with a thesis :D10:50
@HeikoSlisitsyn: is this shogun related?10:50
@wikingit never goes below 25 :D10:51
@lisitsynHeikoS: yes possibly10:51
@HeikoSlisitsyn: I have an idea10:51
@lisitsynI can force student to write shogun code10:51
@HeikoSlisitsyn: there is this work by andrew wilson10:51
@HeikoSon spectral mixture kernels10:51
@HeikoSlisitsyn: that is a nice gsoc project10:51
@HeikoSbut maybe its interesting for your student10:51
@lisitsynHeikoS: well we can force it before10:51
@HeikoSthe idea is to take fourier transoform of kernel, then put a gaussian mixture on the frequency coefficients, and then learn the parameters like this10:52
@lisitsynif someone takes that he would start in december10:52
@HeikoSlisitsyn: this gives a very flexibly family of kernel functions which is easy to learn10:52
@HeikoSlisitsyn:  in some sense similar to a multiple kernel learning regression, but way easier10:52
@lisitsynwhat do you mean by fourier of kernel?10:52
@HeikoSworks with GP framework10:52
@HeikoSlisitsyn: write it in frequency space, see bochners theorem10:52
@wiking(t) -> (omega)10:53
@lisitsynhmm no I mean I am confused with that because we usually transform a vector10:53
@HeikoSlisitsyn: see section 210:54
@lisitsynwiking: want to kill me with math? :D10:54
@HeikoSlisitsyn: you want to look up bochers theorem10:54
@wikinglisitsyn: heheh it's a very simple integral10:54
@HeikoSlisitsyn: no thats easy10:54
@HeikoSlisitsyn: idea is that you represent the kernel in frequency space and learn parameters there10:55
@wikingeven a horse can do that ft10:55
@lisitsynhmm yeah I've got10:55
@HeikoSlisitsyn: which seems a bit easier since one doesnt have to decide on a parametric form10:55
@HeikoSlisitsyn: they apply this to image inpainting10:55
@lisitsynHeikoS: but you've got to choose the kernel still?10:55
@HeikoSlisitsyn: but one can use this spectral mixture kernels to do say regression10:55
@HeikoSlisitsyn: no10:55
@HeikoSlisitsyn: the spectral mixture kernel is the kernel10:55
@HeikoSjust need to learn gaussian mixture components10:56
@lisitsynahh so the trick is that we learn the kernel10:56
@HeikoSlisitsyn: which can be done via marginal likelihood optimisation10:56
@lisitsynGMM of fourier coefficients?10:56
@HeikoSi.e. bfgs or gradient decent10:56
@HeikoSlisitsyn: yes10:56
@wikinghehe that's a funny idea10:56
@lisitsynthat's pretty vague for me but sounds cool10:56
@lisitsynHeikoS: the main question is10:56
@lisitsynhow can one do something about that that is 'defendable' :D10:57
@lisitsynI mean they already have this method - what can I suggest to do about it?10:57
-!- PirosB3 [~pirosb3@] has joined #shogun10:57
@wikinglisitsyn: it's a BSc10:59
@wikinghe just have to do a review of it10:59
@wikingi reckon10:59
@lisitsynhmm well10:59
@wikingand maybe apply to a dataset10:59
@lisitsynyeah but I am like responsible10:59
@wikingthat hasn't been evaluated yet10:59
@wikinghe doesn't have to come up with something novel10:59
@wikingit's not going to be published in a journal or? :D10:59
@lisitsynwiking: well I can also have masters student :D11:00
@wikingsame applies11:01
@wikingnever heard of some project11:01
@wikingi mean msc project has to be something totally novel11:01
@lisitsynnot totally novel11:01
@wikingi mean it wouldn't even be feasible11:01
@wikingi really reckon11:01
@wikingsomething like11:01
@lisitsynI just don't know what are points of extension here11:01
@wikingimplementing it within a framework11:01
@wikingusing some interesting datasets11:02
@wikingthat sort of things are fine enough for a BSc/MSc thingy11:02
@lisitsynyeah I will give him interesting datasets :D11:02
@HeikoSlisitsyn, wiking this is quite nice for extrapolation11:02
@lisitsynterabytes of interesting datasets11:02
@HeikoSso maybe a dataset where one needs to extrapolate11:02
@HeikoSimage inpainting11:02
@lisitsynI have a few11:02
@HeikoSregression for prediction of future11:02
@lisitsynokay I'll suggest that11:03
@HeikoSlisitsyn: check out the GP book11:03
@HeikoSthere is this co2 example in there11:03
@HeikoSin the book, they manually come up with a combination of 5 kernels11:03
@HeikoSthen learn the parameters of the combination11:03
@HeikoSwith the spectral mixture, its only learning parameters of one kernel11:03
@lisitsynthat's cool11:03
@HeikoSlisitsyn: for shogun, all to do is to implement 1 more kernel, then plug into existing framework11:03
@lisitsynHeikoS: is it possible to make it scale?11:03
@HeikoSand then notebook11:03
@HeikoSlisitsyn: if your input space lies on a grid, then one can speed this up quite a bit11:04
@HeikoSlike images11:04
@HeikoSsee paper11:04
@lisitsynHeikoS: what's grid but not image?11:05
@lisitsyncan I treat some user behaviour wrt time as grid11:05
@HeikoSlisitsyn: it always depends on whether the arguments to the kernel are on a grid11:06
@HeikoSso depends on your feature space11:06
@HeikoSbut I guess not11:06
@lisitsynHeikoS: well time is like per second11:07
@lisitsynisn't it grid?11:07

USCwhy is this that complicated11:29
@wikingapt-get install it11:29
@wikingUSC: i reckon this is rather easy11:29
@HeikoSwiking: what about removing the precise build?11:30
@HeikoSwiking: oh and could we add opencv to the nightly build or something?11:30
@wikingHeikoS: it's there11:30
@wikingjust the version is not good11:30
@wikingbut not much i can do about that atm11:30
@HeikoSwiking: really, ah sorry then, which build?11:30
@wikingdon't want to install something from src11:30
@HeikoSwiking: yeah agreed11:30
@wikingand i couldn't find a newer deb package11:30
@HeikoSwiking: just wanted to have kislays tutorial be part of the continuous testing11:30
@wikingHeikoS: mmm i reckon maybe we could use the trusty bot for that11:31
@wikingi'll check the version of opencv in ubuntu trusty11:31
@HeikoSI mean we dont need that on travis, as its unlikely to break, but still would be good11:31
USCwiking: how will I download a compiler and the g++11:31
@HeikoSif you do it, could you send me an email?11:31
@HeikoSUSC: google the question11:31
@HeikoSUSC: thats very standard11:31
@HeikoSUSC: depends on your operating system, etc, but it is VERY easy11:32

@wikingUSC: i mean can i ask you why would you like to use shogun, for what purpose?11:33
@wikingHeikoS: mmm yeah it's 2.4 so i reckn that a good version for the opencv integration11:33
USCgreat write me the command for compiler too please wiking11:33
@wikingUSC: ?11:33
@wikingUSC: this is not a wishlist channel11:34
@wikingthat's like on amazon.com11:34

@wikingregarding who's doing some shit wrong11:40
@wikingbut i can give a quickfix11:40
@wikingand this is only python related11:40
@wikinglisitsyn: basically if u remove those to swig parameters11:41
@wikingthe whole python modular will just work fine11:41
@HeikoSwiking: cool11:42
@HeikoSwiking: so thats all from you11:42
@HeikoSwiking: what about osx?11:42
@HeikoSwiking: me and fernando need to write blogpost, but that can be done while releasing11:43
@wikingHeikoS: that's the last remaining error i need to fix11:43
@wikingand then i'm good to go11:43
@HeikoSwiking: cool11:43
@wikingi'll try to get an answer from swig ppl11:43

@HeikoSshould try hamburg for that11:55
@HeikoSits so fun its almost scary11:55

@wikingHeikoS: no build11:55
@wikingi need to merge in still the /debian thingy11:55
@HeikoSwiking: should I already put link in NEWS?11:56
@wikingmm yeah definitely11:56
@HeikoSwiking: any other things to put that you did? currently updating11:56
@HeikoSswig3 support? :D11:57
@wikingmmm yeah that could be it11:57
@wikingwill be in soon11:57
@wikingupdating c# interface for mono 3.x11:57
@HeikoSis that us?11:59
@HeikoSkind of had in mind yours is different11:59
@wikingah yeah it is11:59
@wikingbut it's owned by soeren :D11:59
@HeikoSwhere is yours again?11:59
@HeikoSwiking: btw this colpack dependency .....12:08
@HeikoSwiking: kind of annoying for the binary, do you think maybe we should exclude the log-det stuff12:08
@wikingwell i mean if you add 1 ppa12:08
@wikingyou can add 212:08
@HeikoSwiking: and how will this nightly thing work? will some build upload a package? or does launchpad have their own distribution12:09
@HeikoSwiking: you are right :)12:09
@wikingwell that's the thing12:09
@wikingi was working on generating the package itself12:09
@wikingbut then it came out that ppa just needs the rule files + src targz-ed12:09
@wikingand ubuntu's build system will create the packages itself12:09
@HeikoSi see12:10
@HeikoSthats nice right?12:10
@HeikoS- Fixes for SWIG3 [Viktor Gal]12:11
@HeikoS- Fixes for C# and Mono312:11

@HeikoSanything else?12:11
@HeikoSok cool, Ill put it in now ...or shall I wait? whats the ETA?12:13
@wikingthis week12:13

@HeikoSshogun-buildbot, force build "nightly_default"12:49
shogun-buildbotThe build has been queued, I'll give a shout when it starts12:49

USClisitsyn: I'm not stupid, but the team behind shogun..12:50
@lisitsynUSC: prove it ;)12:50
USCknowing how to use linux doesn't mean smart, if it is not smart, it is stupid12:51
@lisitsynyeah sure we are just monkeys that learnt how to use linux12:51
@lisitsynbut your proof has some flaws yet12:52
@HeikoSUSC: sorry for redirecting you, the thing is that we have way too much work than time, so if we can we tell people to read the docs as it saves us time to help with shogun questions12:52
@wikingUSC: i seriously reckon you should reiterate your thoughts before writing them down...12:53
@wikingif u came here to insult people then please leave12:53
USCif you were smart enough, you would be able to create a software not a bunch of files12:53
USClisitsyn: start it, read the chat above12:53
@wikingall of us works hard on this project for years... in our spare time12:53
@lisitsynso you imply that any cmake based software is just a bunch of files :D12:54
USCwiking: lisitsyn started this converstation, he has to apologize12:54
@wikingand you coming it here and start insulting people is not the most decent things to say12:54
@lisitsynI have to what? :D12:54
@wikingUSC: are you like 8?12:54
USCno I'm just 4, will be 5 in 4 months12:54
@wikingi mean dont get wme wrong it would be awesome12:54
@wikingif you'd be 8 and want to use shogun12:55
@wikingbut i seriously doubt that12:55
@lisitsynyeah absolutely12:55
@lisitsynyou would be younger than shogun itself12:55
USChow old are you wiking ?12:55
@wikingabout to be12:55
USCwhen I become 8, you will be still trying to develop shogun,12:55
@wikingok so let's make something clear12:56
@wikinghave u came here to troll?12:56
@wikingthen please stop12:56
-!- shaochuan [] has joined #shogun12:56
USCI just want to say that you need be respectful to the people who're trying to use shogun, you can't call them stupid12:57
USCI have never seen ubuntu or cgywin or others before12:58
@HeikoSUSC: actio re-actio, lets drop the subject and talk about constructive things12:58
@lisitsynhah so you want to turn it like we just insult you for nothing12:58
@HeikoSUSC: that is fine, as I said, we are happy to help you, but we cannot help you with basic linux questions, there are other places for this12:59
USCdo you see lisitsyn? he is not happy12:59
@wikingusc fyi there are other fine machine learning libraries you could use on your machine13:00
@wikingnobody is forcing you to use shogun13:00
@lisitsynstop playing victim you started this thing on kill shogun :D13:00

@lisitsynI had enough vodka today to answer this :D13:01
@wikingi reckon we had the most action here ever since august :D13:02
USCit was just a joke, vodka is killing your brain if you have it already13:02
@wikingUSC: pleaase try to avoid going into personal things and just stick to the questions of shogun.. thnx heaps13:03
@HeikoSgotta go, cu guys13:04
@HeikoSwiking, lisitsyn13:04
@HeikoScan you make this?13:04
USCcan I ask a question about shogun project?13:04
@lisitsyndoesn't work for me it seems13:04
@lisitsynUSC: absolutely :D13:04
@HeikoSlisitsyn: ok, wiking?13:04
@wikingHeikoS: not me... its way to late13:04
@wikingi'm GMT+813:05
@HeikoSwiking: ok, whats the last time you can justify13:05
@HeikoSwe should get those meetings going again13:05
@wikingwell 1am here.. which is 6pm there13:05
@wiking6pm CET13:05
@wikingi.e. 5pm GMT13:05
@HeikoSI will be back at 6 then13:05
@lisitsynit would work for me but not today it seems13:05
@wikingHeikoS: yeah it's way to early13:05
@wikingbut tooday i told you13:06
@wikingthat i'm having13:06
@wikingthe dataincubator thing13:06
@wikingso i'm like nogo13:06
@HeikoSwiking, lisitsyn ok I will just do the meeting on my own, and then pretend it was full so people will com enext time ;)13:06
@HeikoSwiking: ah I see,13:06
@HeikoSgood luck with that13:06
@HeikoSwell ok, see you later13:06

USCcan I ask a question about shogun project?13:08
USCwho is behind it? who is the boss? is he paying you?13:09
@wikingit's an open source project that is being developed by volunteers13:11
@lisitsynyeah so wiking wasn't not paid to answer your questions - that's why he was surprised by your demand13:15
USCwhat about a referral system? like libsvm does?13:17
USCciting in academic articles13:18
USCare you all academicians?13:18
USCcan you please check this13:23
USCwiking: is it okay?13:24
@wikingseems like13:25
USClastly, can you please tell me what do I do now :)13:25
@lisitsynyou can now do make install13:26
@lisitsynand use shogun13:26
USCI did "make install"13:27
USCbut how will I run it :)13:27
@wikingUSC: could you please elaborate why you want to use shogun and for what13:28
@wikingplease not that this is really not a machine learning toolbox for rookies13:29
@lisitsynyou've got to write a program that uses shogun13:30
USCI want to use shogun's MKLRegression model for prediction13:30
@lisitsynin any of languages we support13:30
USCI have 23 dependent 1 independent variable,13:31
@lisitsynwhy mkl?13:31
USCbecause I tried libsvm with gaussian kernel, the result is not bad but not perfect13:32
USCso I want to try multiple kernels to see hopefully better results13:32
@lisitsynplease note that shogun is not like libsvm (command line tool) but a library13:33
@lisitsynyou'd have to read your data create objects etc13:33
@wikingso you would need to implement the whole thing using one of the supported languages13:34
@wiking(c++, python, ruby, java etc)13:34
@wikingthere's no ./mkl-train <data>13:34
@wikingUSC: check out the examples13:35
USCthank you very much13:35

@wiking"From an algorithmic point of view, the computational cost associated with the calcula- tion of any entry of a nxn covariance matrix using a path-sum is known to be O(n) on trees,"16:55
@wiking"The O(n) complexity is achieved for the most general situation; if J or G has symmetries, the complexity would be lower. Evaluating the complexity of the path-sum approach on a graph with an arbitrary topology remains an open problem. Since the method of path-sums arises from exact resummations on walk-sums, every problem that has a walk-sum interpretation is susceptible to these resummations and therefore admits a path-sum expression. Consequently, ev16:56

@wiking"We show that the path-sum formulation formulation is valid for arbitrary partitions of the inverse covariance matrix"17:21

mrbelthey there, this noob has a question for you18:09
mrbelthow would you use backwards elimination or forward selection inside cross-validation? i really can't find any examples out there18:10
mrbelti'm using the python modular interface, BTW18:10
@iglesiasgmrbelt: randomising the mechanism that chooses the order in which predicted variables are selected?18:28
@iglesiasgmrbelt: I have no experience on doing it though. Just a random idea :)18:29
