foulwallhushell: huh, I found you're chinese08:23
hushellfoulwall: :) nice to meet you08:23
foulwallhushell: nice to meet you :)08:23
hushellfoulwall: I am a bit busy on writing :( we could talk later08:24
foulwallhushell: ok08:24
hushellfoulwall: have fun08:24
@sonney2kgood morning foulwall08:28
@sonney2kfoulwall, I've seen you have a blog too? Is it OK if I connect you to shogun toolbox planet?08:28
foulwallsonney2k: ok08:29
@sonney2khushell yes today and good luck with your paper!08:29
@sonney2kfoulwall, did you think about how to structure the code?08:30
hushellsonney2k: thanks! As you predicted, I will have to fight until last min08:31
foulwallI'm now modifying the 'argument' panel ,  I think the panel can be defined in the .py files, only have to provide the label and the type of input.08:32
@sonney2kfoulwall, you are live http://shogun-toolbox.org/page/planet/shogun!08:32
foulwallsonney2k: thanks08:33
foulwallI have seperated the messy template into a general framework and little modules, and sent a pr already. I'm doing the next step seperation08:35
foulwallsonney2k: There's two slashes here in the plannet page. You are here: planet  /   /  shogun08:42
@sonney2kfoulwall, hmmhh if you have time check shogun-web and fix this bug08:44
@sonney2kfoulwall, nice08:44
foulwallsonney2k: ok08:45
@sonney2kfoulwall, I have to go now but will have a look asap08:45
foulwallsonney2k: cu08:45
sonne|workfoulwall: yes looks fine08:58
sonne|workfoulwall: maybe you can generalize further - I mean each demo could be in one .py file08:58
sonne|workso you could have some global variables describing the demo or so08:59
sonne|workand some super class that could set these common properties08:59
foulwallsonne|work: I'll have a try of that, but first I'll organize the argument input section.09:00

sonne|workfoulwall: there might be a couple of methods to solve the same thing09:01
sonne|worke.g. binary classification09:01
sonne|workyou will have binary svm (via libsvm)09:01
sonne|workbinary svm (via svmlight)09:02
sonne|worketc etc09:02
sonne|workto it might make sense to build a hierarchy to re-use common blocks09:02

@lisitsynvotjakovr: I am just curious if you have some plan for next weeks09:11
votjakovrlisitsyn: Hi, yep :) The main goal is to finish polishing existing GPR and discuss architecture of GPC before the 17th of June. I'll post my future plans in more details in my blog, which i'm setting up currently. And I'll send a link on my blog in mailing list in introduction theme.09:25

My first goal of the project is finish a simple CRF framework, so I also need to reference other CRF lib, otherwise my code definitely creepy :)09:48

oshoiam trying to seek an answer for the query? i tried mailing list but either it bounced or no reply12:01
@wikingsonne|work: where?12:01
@iglesiasgosho: what problem is it?12:01
@iglesiasgwiking: the gmock PR I think12:02
oshoi am trying to use WeightedDegreePositionKernel with Shift12:02
@iglesiasgwiking: https://github.com/shogun-toolbox/shogun/pull/113312:02
@wikingubuntu gmock package is fucked12:02
sonne|workosho: did you subscribe to the mailinglist?12:02
oshoand even though i think i am setting it right...it fails in numpy-swig to c++12:03
oshoyeah...12:03
@wikingwho's  Open12:03
@wikingtklein2312:03
@wiking?12:03
sonne|workosho: when did you send the email?12:03
@iglesiasgosho: how does it fail?12:03
osho2 days back12:03
sonne|workwiking: thoralf12:03
oshohere is the mail chopped...12:03
sonne|workosho: sure you subscribed?12:03
@wikingthoralf: you are wrong :D12:04
oshoyeah will try again ..12:04
osholet me see if i can paste my mail here in parts12:04
oshoI would really appreciate a feedback or help. I have regulatory region in DNA sequences, and was trying to use WeightedDegreePositionStringKernel. I looked at the constructor documentation and wanted a degree=8 and shift=3. I created kernel like12:04
oshofrom numpy import zeros,ones,float64,int32 shift_vector = ones(len(fm_train_dna[0]),dtype=int32) weight_vector = ones(len(fm_train_dna[0]), dtype=float64) degree=8 cachesize=500 kernel=WeightedDegreePositionStringKernel(cachesize,weight_vector,degree,0,shift_vector,3,1) kernel.init(feats_train,feats_train)12:04
oshoit fails12:04
oshoThe script throws error at constructor saying     kernel=WeightedDegreePositionStringKernel(cachesize,weight_vector,degree,0,shift_vector,3,1) NotImplementedError: Wrong number or type of arguments for overloaded function 'new_WeightedDegreePositionStringKernel'.12:05
oshoI think it should match exactly with  CWeightedDegreePositionStringKernel(int32_t size, float64_t * weights, int32_t degree, int32_t max_mismatch, int32_t * shift, int32_t shift_len, int32_t mkl_stepsize = 1 )12:05
oshoany help appreciated ..12:06
@lisitsynargh12:06
@lisitsynosho: I recognize the error12:06
@lisitsyniglesiasg: votjakovr: anyone has some time?12:07
@lisitsyniglesiasg: ahh you do your thesis stuff :)12:07
@iglesiasglisitsyn: to look at osho's error?12:07
@iglesiasglisitsyn: yep12:07
@lisitsynint32_t * shift, int32_t shift_len12:08
@lisitsynthat's the cause12:08
@iglesiasglisitsyn: aah it shouldn't be int32_t* I understand12:09
@iglesiasgSGVector instead12:09
@lisitsynyes12:09
@lisitsynsame with weights12:09
oshoanything i have to do?12:10
@iglesiasgosho: that needs to be patched in the C++ code I believe12:10
@lisitsynosho: I don't think you'd like to mess with that :)12:10
osho:-)12:10
@iglesiasglisitsyn: it shouldn't be hard to patch though, right12:11
@lisitsynosho: I am running out of time now but I can fix it tonight12:11
@wikingthoralf: there's your answer in the PR12:11
@wikingit's not going to be accepted12:11
@wikingthoralf: you'll *need* gmock source12:11
oshook i will try to subscribe again with mail list and send so that it would be useful for others12:12
@lisitsynosho: yes thanks12:12
oshothe weird thig is i get emails from the list12:12
oshobut when i send it doesnt go through12:13
oshoanyways will try again12:13
@wikingbtw do we have a decision on the gsoc students? :)12:15
@wikingand wtf should i do with multiple machines (see baggingmachine)12:15

@wikingsonne|work: soooooooo, what shoudl we do about clone machine ?:)12:20
@wikingsonne|work: elaborate :D12:20
@lisitsynsonne|work: what is it?12:20
sonne|workwiking: don't clone for now just do it serial for the time being. Heiko & lambday are doing a framework that you can use later for parallel stuff12:21

@wikingsonne|work: serial? :)12:22
@wikingsonne|work: no i mean i need n clones for each maof a given machine12:23
@wikingsonne|work: even if i dont do parallel12:23
sonne|workwiking: well assume you get the machine as object12:23
sonne|workthen you don't need to clone12:23
sonne|workwhy?12:23
@wikingsonne|work: because i need ot classify with it after the train12:24

@wikingand classification is a voting scheme12:24
@wikingsonne|work: so the only way to do this atm actually12:24
@wikingis to train a one machine12:24
-!- mode/#shogun [+o iglesiasg] by ChanServ12:24
@wikingsave the model12:24
@wikingreset the machine12:24
@wikingtrain again and save again12:24
@wikingdo this n times12:24
@wikingand when classification is needed (why else would you do bagging :P)12:25
sonne|workwiking: yes...12:25
@wikingthen you need to deserialize each machine12:25
@wikingand classify with them12:25
@wikingright? :)12:25
@wikingthis is doable of course12:25
@wikingbut a lot of waste of resource ;P12:25
@wikingthat's why we would need clone machine to be able to have all those machines in memory12:26
@wikingand not on disk12:26
thoralfwiking: Okay, thanks.12:40
thoralfwiking: So why do you check for /usr/include/gmock anyway?12:41
thoralfwiking: If someone has the source, then the includes can be found in the same directory. ;)12:42
@wikingthoralf: because we are hoping12:44
@wikingthoralf: that distros will fix this the same way as it's fixed with gtest packages12:45
@wikingthoralf: headers are in /usr/include/gtest12:45
@wikingwhile the source is under /usr/src12:45

sonne|workiglesiasg: but what for? all we do is open source13:21
@iglesiasgsonne|work: not for shogun-ing, but maybe someone wants it for his/her private stuff13:22
@iglesiasgthere were already available with bitbucket though13:22

@HeikoSmy uni is paying for this13:41
@HeikoSand its a pain to get those13:41

@iglesiasgthen thank your uni on my behalf please :)13:41
@HeikoSiglesiasg: ah well13:41
@HeikoSthis is not for research13:41
@iglesiasgHeikoS: just students I think13:42
@HeikoSyeah for courses and stuff13:42
@iglesiasgand there is something about organization accounts as well13:42
thoralfI'm having issues with two unit tests: classifier_svmlight_string_features_precomputed_kernel, library_map.  Both of them are complaining about "undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'"13:42
thoralfEven though the configure script detects posix threads properly.13:42
@HeikoSiglesiasg: but actually, I will request this once I am a phd student :)13:42
@HeikoSthoralf: weird, maybe lisitsyn know whats causing this?13:43
thoralfI saw in the archive, that this problem is known, but did not find a solution.13:43
@iglesiasgHeikoS: ;) do you know something about it btw? I mean any position you are applying for or so13:43

@HeikoS :)14:56
@wikingHeikoS: any ideas how to go ahead with machine cloneing? :)14:56
@HeikoSwiking, yes parameter framework14:59
@wikingelaborate :)15:00
@HeikoSwiking: so every instance has parameters ergistered15:04
@HeikoSso one can just iterate over them and copy contents to another instance15:04
@HeikoSfor this, TParameter would need a clone method15:04
@HeikoSfor this, one needs to distinguish all the cases in there15:04
@HeikoSwhich is very similar to the equals method I wrote( which is not yet finished)15:05
@HeikoSso have a look at that15:05
@HeikoSso we only have to write code once15:05
@HeikoSand all classes get a clone15:05

van51hi all21:01
@sonney2kAlright then lets start! Good morning, afternoon, evening and night everyone!21:01
lambdayhi van51 :)21:01
@sonney2kWelcome to our kick off meeting.21:01
foulwall_yep21:01
hushellfoulwall_: you are also late person21:01
@sonney2kCongrats students for being accepted. We are very happy to work with you.21:01
@sonney2kThis year we have a new record 8 students in 8 timezones so apologies to flouwall, votjakovr for having to suffer next time we will arrange sth more suitable.21:01
@sonney2kFirst I would like to thank you all for your hard work even before GSoC started. We are happy to have you in the team and you were selected because we know you will have no problems finishing the tasks with 100% success while even enjoying what you do :-)21:01
@sonney2kBTW if anyone has any question. Please interrupt me and ask it at any time.21:02
@sonney2kNevertheless, some of us {mentors,students} participate for the first time so let me briefly state how things work - lets start with the timeline:21:02
@sonney2k-  Official GSoc starts June 1721:02
@sonney2k- On August 2 Mentors need to send mid-term evaluations to google (*very important* - students won't get money otherwise) and students need to send in evaluations too.21:02
@sonney2k- September 27 end of GSoC - Mentors need to send final evaluations to google (again *important*) - and students too + upload code to code.google.com.21:03
@sonney2kJust check the official timeline https://google-melange.appspot.com/gsoc/events/google/gsoc2013 if you have concerns21:03
@sonney2kAlright now for some general comment21:03
@sonney2kPlease avoid any private communication to the extend possible, i.e., discuss all issues openly on the mailinglist or here in IRC.21:04
@sonney2kIf you ask yourself why this is not the way open source projects work21:04
@sonney2kAll development and even planning is done in the open.21:04
@sonney2kThis is particularly important here because not all mentors/students can be experts in everything.21:04
@sonney2kFor example a mentor might not know about certain data structures that one could use (that are already in shogun).21:04
@sonney2kThe advantage of asking in public is that other students/mentors can help out -21:05
@sonney2k potentially even more timely (8 timezones covered!) than your mentor and we are working *together* in this project so there will be synergies.21:05
@sonney2kWe had that last year for the structured output project, but I guess sth similar will happen this year again.21:05
@sonney2kAnd again we cover enough timezones so you should never be alone - which makes it much more fun too21:05
@sonney2kNow what is expected from mentors:21:06
@sonney2k- Guide your students like any PhD/Master student. Run a tight ship in the first few weeks to get things on track and then things will work w/o a lot of intervention.21:06
-!- chap [c7cca90a@gateway/web/freenode/ip.199.204.169.10] has joined #shogun21:06
@sonney2k- Try to keep students happy (answer quickly, monitor happiness).21:06
@sonney2k- Participate (in relevant) public discussions.21:06
@sonney2k- Review student patches at github (give comments) - technical review / coding style etc will be done by mostly lisitsyn, iglesiasg, HeikoS and me. Once you are satisfied notify any of us to actually do the merge.21:06
@sonney2k- you have to evaluate your students (2 times, midterm, end of GSoC).21:07
@sonney2kthis is rather cheap (just some forms to click and can be done in 5-10 mins)21:07
@sonney2k- now a question21:07
@sonney2kWho wants to go to Mentor summit @Google (October 19 & 20)? Say now or write-  me an email.21:08
lisitsynif there is no one I do21:08
@sonney2k- For further questions there is the mentor manual https://flossmanuals.net/gsocmentoring/21:08
@sonney2klisitsyn, I recall HeikoS would want to go too. And who knows maybe chap wouldn't mind to party too :D21:09
@sonney2kAlright mentors - any questions so far?21:09
lisitsynsonney2k: I will have visa troubles anyway so if HeikoS wants I don't mind21:09
@sonney2kaz_de, patrickp, chap ?21:10
patrickpwell, where would it be? Any of the google offices?21:10
@sonney2klisitsyn, I am sure you and a few more can go.21:10
@sonney2kpatrickp, yes mountain view21:10
patrickpbut only mountain view?21:10
lisitsynsonney2k: ? is that just refund of 2 slots21:10
lisitsynI mean can we send a few mentors there?21:11
@sonney2klisitsyn, 2 mentors but I've met the orange guys (from orangle ml toolbox) and they were 4 or 5 :D21:11
@sonney2kthough they were working on some grand proposal most of the time...21:12
@sonney2kanyways further questions?21:12
lisitsynoh I see okay lets see how many do we want and ask carols21:12
@sonney2kyeah decide for yourself early so we can ask early to ensure everyone could go.21:12
@sonney2kOK then next topic:21:12
@sonney2kWhat is expected from students!21:12
@sonney2k- FIrst of all have fun with what you are doing and learn what you always wanted to learn.21:13
@sonney2k-  Start early and stay in regular contact with your mentors in particular in the beginning. Students tell your mentor or me when you feel unhappy. We can adjust (and have done so in last GSoc's) the task to solve.21:13
@sonney2k(or tell lisitsyn or HeikoS or...)21:13
@sonney2k- If you intend to blog, tell me your blog url to add you to shogun planet. I've already added lambday and foulwalls blog to shogun planet http://shogun-toolbox.org/page/planet/shogun .21:14
pickle27my blog is at kevinhughes.ca21:14
@sonney2kpickle27, ok noted will add you after the meeting21:14
@sonney2k- While GSoC is running, students have to send weekly reports to the mailinglist (due every Monday). What is expected here are *very few* sentences. We want you to code not waste your and our time. If it takes you more than 5 minutes then it is not what we are looking for :)21:15
@sonney2k- During normal working hours students have to idle in IRC channel #shogun.21:16
@sonney2k- If you a planning to go on vacations, or be away for whatever reason (exams, ...) - no problem but please notify us *upfront*.21:16
@sonney2k- To pass mid-term you should write a summary (draft status) of your work that contains an overview, screenshot, main classes written, some nice example application - mentors help students to find some nice illustrative application.21:16
@sonney2k- To pass final this no longer should be drafty.21:16
@sonney2k- Further information can be found in https://flossmanuals.net/GSoCStudentGuide/21:17
@sonney2k- I am sorry to say this, but please note that based on experience from last year we will have to be very strict about weekly reports, that students stay in IRC during their working hours and the work summary and fail students.21:17
@sonney2k- That said, you are pretty free to work on what you like and vacations and almost anything is possible. But please talk to us.21:18
@sonney2k- If you have questions, you can ask wiking, lisitsyn, HeikoS, iglesiasg - they all were (successful) GSoC students in previous years.21:18
@sonney2kDoes anyone have any questions regarding to that?21:18
@sonney2kOr concerns or find this unfair?21:18
lambdayI'm not sure about what you meant by normal working hours... we all are from different timezones21:19
@sonney2kYou can also msg or email me in private21:19
@sonney2klambday, your working hours21:19
lisitsynlambday: well your working hours21:19
lambdayokay21:19
lisitsynit is not going to be tracked for sure21:19
@sonney2klambday, and yes you can choose the time zone you want to work :D21:19
lambdayokay :D21:19
pickle27okay I was going to ask that too but that makes sense21:19
@sonney2klambday, even work, sleep, party, work, sleep party or whatever rotation scheme fits you best21:20
lisitsynbut we just need to know you are doing the work you intended to work21:20
lisitsynyeah I had to virtually change my timezone21:20
lisitsynwhen working with cwidmer21:20
@sonney2kand besides it is much more fun when you are not alone and someone in the channel can talk to you21:20
pickle27I guess I'll mention now that I am travelling to a few conferences and I will be getting back to my home on June 17th right when GSoC starts21:20
pickle27I'll still be working and preparing but my IRC ideling might be a bit spotty21:21
pickle27until I am back21:21
lisitsynpickle27: good you noticed that ;)21:21
@sonney2kpickle27, thanks for letting us know21:21
@sonney2kmore questions?21:21
hushellwhat if the original schedule is delayed?21:22
lisitsynhushell: that's ok21:22
@sonney2khushell, we will work something out.21:22
pickle27for the email updates should we settle a UTC based deadline? Monday is a bit arbitrary21:22
@sonney2khushell, Usually there are unforeseen obstacles that are not your fault.21:22
@sonney2kpickle27, timezone of your choice monday21:23
pickle27sonney2k, okay21:23
@sonney2kbut not already now during official GSoC21:23
pickle27yup21:23
hushellI will work hard and try not to fail anyway :)21:23
@sonney2khushell, I don't expect anyone here to fail. You all already showed that you can do much more than we ever dreamt of21:24
lisitsynhushell: why do you think of it? if you have doubts we should update the schedule21:24
@sonney2kso if no one runs away from us screaming21:24
@sonney2kthere is no problem21:24
hushellI just ask the worst end. I am confident about my current plan21:25
lisitsynalright21:25
lambdaydo our working hours have to be continuous, during official gsoc?21:25
@sonney2khushell, well the only way to fail really is not to do work / no longer be around21:25
@sonney2klambday, of course not21:25
lambdayokay21:26
@sonney2klambday, if you want you can sleep every 30 mins21:26

hushellsonney2k: that's easy :) But I should go far beyond21:27
lambdayshouldn't be a problem then :)21:27
@sonney2kFrom last years experience: It is difficult to come up with some application / example that is fancy.21:28
@sonney2kSo please already now start to think about it. Everyone can then present his idea for an example in the next meeting.21:28
@sonney2kHeikoS, lisitsyn - did I miss anything / does anything else come to your mind?21:29
lisitsynno that sounds complete21:29

@sonney2kanyways any further question?21:32
az_dehow does this work ?21:32
patrickpis there some form of wiki for designing a class or something? Or what do you use for this purpose? IRC seems a bit odd, and directly starting a cpp file maybe a bit premature...21:32
lisitsynsonney2k: may be mention workshop?21:33
@sonney2kiglesiasg, you did that last year ^21:33
@iglesiasgsonney2k: a wiki for lass design?21:33
@sonney2klisitsyn, indeed - anyone up to visit berlin this summer for the shogun ml workshop?21:33
@iglesiasgmm I don't recall doing that21:33
@sonney2kiglesiasg, how did you do it last year?21:33
patrickpjust some google docs or something21:33
@iglesiasgaaah ok, I think you are talking about the diagram21:34
@sonney2kiglesiasg, sure21:34
pickle27is there a deadline to sign up for the workshop?21:34
lisitsynpatrickp: well we don't have any specific way to do that - if you have ideas please suggest/use :)21:34
lisitsynpickle27: no21:34
pickle27I might consider it!21:34
@iglesiasgI did some simple UML diagrams before starting to code21:34
@sonney2kaz_de, well just talk and make a plan / or send what you have in mind...21:34
@iglesiasgit turned out to be pretty useful to discuss with my mentor21:34
lisitsynpickle27: az_de: please do "/join #shogun_bss"21:35
patrickpcool, just wanted to know whether there already exists something. Thanks21:35
lisitsynif we have noise here ;)21:35
@iglesiasgpickle27, hushell : this is the diagram I meant http://iglesiashogun.wordpress.com/2012/05/22/first-weekly-report-gsoc-2012/21:35
lisitsynotherwise lets talk here21:35
@iglesiasgI used lucidchart for doing it21:35
@sonney2kpatrickp, that's what you meant right?21:36
patrickpyes, looks good, thanks.21:36
pickle27yeah thanks!21:36
@sonney2kok then I think the only thing left to decide is when we meet next21:36
hushelliglesiasg: I had read it from your blog :D21:37
@iglesiasgpatrickp: later when the coding time came, I drew inspiration from existing code21:37
@sonney2k(we should do so about once per month)21:37
@sonney2kI would say right after GSoC is officially started and pickle27 is back21:37
@iglesiasghushell, patrickp : I take advantage to say that please feel free to make any re-design to the structured framework21:37
@sonney2kso June 18?21:37
@iglesiasgif anything looks weird, it may be that something is not really well designed21:38
pickle27could we do the 19th?21:38
@iglesiasgnothing is set on stone :)21:38
hushellI also agree to start with a design and discuss in public21:38
patrickpiglesiasg: we'll look into it in the next weeks, i'm sure will contact you a couple of times :)21:38
pickle27sonney2k, can we do the 19th?21:38
hushellsince we have 2 weeks more before official start21:39
@iglesiasgpatrickp: I am glad to discuss :)21:39
@sonney2kok so how is June 19th say 15 UTC?21:39
pickle27should work for me21:39
patrickpiglesiasg: great!21:39
van51sounds good to me21:39

@sonney2kbtw gsomix how is it going with your ringbuffer now!21:50
gsomixsonney2k, what's about work. there is preliminary version of circular buffer, but I need some time for integrate it with LineReader.21:51
@sonney2kgsomix, ok cool just keep me in the loop21:52
gsomixsonney2k, I can send a PR if this is needed.21:53
gsomixsonney2k, btw, did you receive my introduction letter?21:53
@sonney2kpickle27, you are on http://shogun-toolbox.org/page/planet/shogun21:55
@sonney2kgsomix, no need to send a PR21:55
pickle27sonney2k, does that automatically pull from my blog then?21:56
lisitsynsonney2k: I got asked about R static21:58
lisitsynsonney2k: do we need to save features/kernels/classifiers independently?21:58
@sonney2kpickle27, yes21:58
@sonney2klisitsyn, sorry what?21:58
lisitsynhmm it seems no21:59
pickle27sonney2k, okay I just blog about more than just shogun if that is okay21:59
@sonney2kgsomix, no nothing there yet - when did you send it?21:59
lisitsynsonney2k: what happens when we load a classifier?21:59
lisitsyndoes it set ui_kernel?21:59
@sonney2kpickle27, sure. I do too.21:59
@sonney2kpickle27, that's why it is planet21:59
gsomixsonney2k, 6 hours ago.21:59
pickle27sonney2k, okay right on!21:59
@iglesiasgok guys, see you later!21:59
@sonney2klisitsyn, you cannot load/save a classifier in static22:00
@iglesiasgnice to see you all during the meeting :)22:00

hushellGreat meeting! Thanks guys! CU later22:03
lisitsynsonney2k: what's the status of R modular?22:03
lisitsyniirc it was leaking memory22:03
lisitsynbut other to that - are there any issues?22:04
gsomixsonney2k, btw I had problem with mail before.22:04
gsomixsonney2k, when I tried to answer Kyle McQuisten got  "it was rejected by the server for the recipient domain shogun-toolbox.org by mail.nn7.de"22:04
gsomix*I got22:05
@sonney2klisitsyn, well you can get the model parameters (like alpha/b for SVM)22:05
@sonney2kso you have a way of storing things22:05
@sonney2kgsomix, can you forward that mail to me?22:06
gsomixsonney2k, introduction mail you mean?22:06
lisitsynsonney2k: how hard would it be to implement that thing?22:06
@sonney2kgsomix, no the error email22:07
gsomixsonney2k, yep22:07
@sonney2klisitsyn, hmmhh not so hard IMHO22:07
lisitsynsonney2k: if something has kernel we load it and set to ui_kernel22:07
lisitsynlike that?22:07
gsomixsonney2k, done22:08

vgorbatilisitsyn: errr22:32
vgorbatilisitsyn: yes:)22:32
lisitsynvgorbati: I don't know - it seems a bit too heuristic for me22:32
vgorbatilisitsyn: agree22:33
lisitsynvgorbati: it depends on task though22:33
lisitsynvgorbati: if you model random process you may use ARMA models or so22:34

lisitsynvgorbati: what about implementing it here in shogun?22:38
vgorbatilisitsyn: another thing to implement:) There are already ANN's22:41
vgorbatilisitsyn: what sounds the most interesting for you?:)22:41
lisitsynvgorbati: why for me  :)22:42
lisitsynvgorbati: lets focus the most interesting for you22:42
vgorbatilisitsyn: for shogun I mean22:42
@sonney2klisitsyn, no just load the main classifier. it will then load everything inside itself. then you have to extract the stuff and set it to ui_kernel etc yes22:42
lisitsynahh shogun will eat anything22:42
lisitsynvgorbati: the purpose of life is fun :)22:42
lisitsynsonney2k: yes that's what I mean22:44
@sonney2klisitsyn, and swig & R is in bad shape22:50
@sonney2kbut try I mean suffer yourself22:50
lisitsynsonney2k: uh that was easier that I thought22:54
lisitsynsonney2k: 6 lines patch make it load kernel and features22:54
