stepan_Hi, I'm using shogun::CGMM that needs lapack library, clapack.h. After downloading lapack and clapack.h, compiling my code returns error: error: declaration of C function ‘int dposv_(const char*, const int*, const int*, double*, const int*, double*, const int*, int*)’ conflicts with ../CLAPACK-3.2.1/INCLUDE/clapack.h:3314: error: previous declaration ‘int dposv_(char*, integer*, integer*, doublereal*, integer*, doublereal*, inte09:49
stepan_Please how could I use shogun with lapack?09:49
@iglesiasgstepan_: what OS are you using?09:53
stepan_linux 64bit, Ubuntu09:53
@iglesiasgstepan_: then it is maybe easier to install lapack via apt-get09:55
@iglesiasgapt-get install liblapack-dev I think09:55
stepan_yes, but debian lapack package does not have header files...exactly the package you mentioned09:56
@iglesiasgyou mean the package doesn't install the header?09:57
@iglesiasgare you sure? I think it is enough to use apt-get for lapack with Shogun, no need of manual installing09:57
votjakovrstepan_: which version of ubuntu are you using?09:57

@iglesiasglisitsyn, wiking : same error happends in bsd112:13
@lisitsyniglesiasg: well soeren changed something in json recently12:14
@iglesiasgmaybe SerializableJsonFile is not accesible in python in bsd1 longer?12:14
@iglesiasglisitsyn: aham I see12:14
van51lisitsyn: well we haven't settled down on a specific application yet12:15
van51lisitsyn: what I know for sure atm is that it will be a classification task and it will probably be an interactive application12:15
van51lisitsyn: like the user will upload something, a document, a picture w/e and it will be classified accordingly12:15

van51lisitsyn: the mentors (Olivier and Benoit) suggested a language detection app or a spam filter to show that that the model remains robust12:16
van51even when the feature dimension is reduced12:17

van51also it's not clear to me yet if we will have to do a seperate app for the fast food project12:17
@lisitsynvan51: alright I see12:21
van51lisitsyn: all we have specified for now are the milestones for the project12:22
van51lisitsyn: btw this application has to be ready by the end of GSoC?12:22
@lisitsynvan51: yes12:23
van51lisitsyn: or does it have to be semi-completed by the middle-term evaluation?12:23
@lisitsynvan51: would be nice to have a prototype by midterm indeed12:23
van51lisitsyn: ok thanks12:24
van51well we just have to agree on a domain then12:24
van51because personally I find text classification a bit boring :P12:24
@lisitsynvan51: then we should select something you are not bored with!12:24
van51lisitsyn: yea!12:25
van51lisitsyn: soeren had a nice idea about face detection12:25
van51I will try to subliminally force that :)12:26
@iglesiasgI killed shogun :O12:27
van51iglesiasg: should we stop making plans then?12:28
@lisitsynvan51: well I am not sure you will beat V-J :)12:28
van51lisitsyn: I just looked V-J up :$12:30
van51lisitsyn: I don't have much experience in image mining so that's why I found it most interesting12:30
@lisitsynvan51: viola-jones12:31
@lisitsynadaboost + haar features12:31
@iglesiasgvan51: haha yeah12:32
van51lisitsyn: I see12:33
van51lisitsyn: well I 'll discuss it with them and we'll see12:33
van51lisitsyn: maybe it's ok if we don't beat it :P12:33
@lisitsynvan51: it is ok as what you do is large-scale or so12:34
van51lisitsyn: does V-J scale well?12:35
@iglesiasgvan51: from when I implemented V-J I would say a cascaded detector scales well12:39
@iglesiasgwith the number of training examples I am talking about12:40
van51iglesiasg: ok, thanks :)12:45
@iglesiasgit seems it sort of screwed up when I moved a templated method from CustomDistance.h to CustomDistance.cpp12:45
@iglesiasgalthough I don't get why it compiles fine in my machine12:47

@lisitsynfirst of all I want to remind you that once GSoC started all students have to send weekly reports16:04
@lisitsynI hope you do remember it is crucial and is a hard requirement16:05

@lisitsynit is just a few lines on your work16:05
@lisitsynso that's clear I guess? :)16:05
zellerdo they have to officially submit these weekly reports somewhere?16:06
@lisitsynzeller: thanks16:06
@lisitsynreports are supposed to be sent to the mailing list16:06
@lisitsyneach monday16:06
lambdaysending the link of my blog (on which I will update the reports) to the mailing list is cool, right?16:07
@lisitsynlambday: yes indeed but please put some short text to the mail too16:07
lambdayalright16:07
@lisitsynany other questions with reports?16:08
@lisitsynokay16:08
@lisitsynnext point is applications/demos we have to develop this summer16:09
@lisitsynjust to recall you, we have decided that each student has to develop a small demo which shows the project he was working at16:09

@lisitsynlast time we decided to think about possible demos, so lets talk about them one by one16:10
@lisitsynwho wants to start?16:10
pickle27I can16:10
@lisitsynaz_de: pickle27: lets talk about your project then :)16:10
@lisitsynplease continue pickle2716:11
pickle27I'm going to be working on algorithms for blind source separation16:11
pickle27for an application we're thinking of an website demoing the algorithm on audio and ekg data16:11

@lisitsynso the user would send some audio file may be16:12
@lisitsynor select one from existing datafiles16:12
pickle27I think that answer will depend on how robust the technqiues are16:13
az_dedoes it have to be a webdemo or just some demo in shogun?16:13
pickle27if they are super robust then definitely let users upload16:13

@lisitsynaz_de: well web based demo is indeed better I think16:14
pickle27az_de, the main advantage would be easy access to the demo16:14
az_deok, if you know how to do that :-)16:14
pickle27possibly getting people interested in actually downloading and using the lib16:14
-!- iglesiasg [~fircuser@m37-197-66-125.cust.tele2.se] has joined #shogun16:15
pickle27anyways so thats what we're thinking for now we'll continually evaluate as we learn and code more116:15
@lisitsynaz_de: well I can help there and I hope foulwall will share some experience too :)16:15
foulwallhi pickle2716:15
pickle27hi foulwall16:15
@lisitsynalright so that's the application: separation of audio files (like two songs at the same time)16:16
@lisitsynlets move on to zeller and iglesiasg project :)16:16
@lisitsyniglesiasg: you are on the phone now, right?16:17
foulwall hoping you can put your web based demo in https://github.com/shogun-toolbox/shogun-demo16:17
iglesiasgyeah! in the subway actually :P16:17
@lisitsyniglesiasg: heh alright16:18
@lisitsynso the project of iglesiasg is large-margin nearest neighbor algorithm16:18
@lisitsynyou may know it is a distance learning thing, it learns a transformation of distance (like mahalanobis with custom matrix)16:18
@lisitsynto obtain largest margin in supervised manner16:19
@lisitsynzeller: could you tell us a bit about the applications?16:20
zellerthe applications I have in mind are mostly from computational biology16:20
zellermetagenomics and chemogenomics16:20
zellere.g. to separate samples of microbial DNA depending on the community from which they were sampled16:21
@lisitsynzeller: what makes LMNN special for these fields btw?16:21
zellerthese communities could be of microbes that colonize the human body16:21
zelleroften you deal with multiclass problems here sometimes with really many classes16:22
@lisitsyniglesiasg: anything else you'd like to say? ;)16:23
zellerthat's also the case for the chemogenomics data set: this contains gene expression changes in cell liens treated with ~1000 drugs16:23
zellerso you can easily have dozens of classes16:23
@lisitsynzeller: so the application (I think we could go web again) would be some plotting of the dataset or may be graphs16:23
-!- iglesiasg [~fircuser@m37-197-66-125.cust.tele2.se] has quit [Read error: Connection reset by peer]16:23
@lisitsynthat tells us we have improvement over say SVM16:24
@lisitsynwhich is not that cool for multiclass16:24
zelleryes and hopefully we can convince people that it works better than standard PCA :-)16:24

zellerthat's one point16:24
pickle27amen to that16:25
@lisitsynheh16:25
pickle27PCA is over used lol16:25
zellerthe other is that these PCA-based techniques are really widespread in these research areas and LMNN can be seen as just a better distance transformation16:25
@lisitsynzeller: yeah so we compare and show an improvement16:25
zellerhopefully giving also better results visually16:25
@lisitsynbut still fancy web16:26
zellersure16:26
@lisitsynso I hope to get it attractive too16:26
zelleralthough I wouldn't know much about how to set this up...16:26
@lisitsynzeller: okay, anything else you'd like to say?16:26
@lisitsynzeller: no worries16:26
@lisitsynwe will guide people here16:26
zellerI guess we could leave it here16:26
pickle27I think we're all a little behind on web stuff so we'll figure it out together!16:27
zellersure cool!16:27
@lisitsynalright, thanks zeller16:27
@lisitsynhushell: patrickp: want to continue?16:27
patrickpwe have actually not yet discussed the demo/applications16:27

ChengHi Sergey, I'm totally messed up with timezones at the moment. At ICML in Atlanta.16:29
patrickphi cheng!16:30
ChengHi foulwall!16:30
@lisitsynCheng: I feel your pain :)16:30
@lisitsynaustralia -> usa16:30
@lisitsynpatrickp: alright so anything else?16:30
ChengSorry to interrupt the discussion16:30
@lisitsynCheng: I guess you are here to talk a bit about foulwall project right? ;)16:30
patrickpAnyway: we could also think of other applications, mostly thinking about computer vision, but they are pretty tricky in this short time frame16:30
@lisitsynpatrickp: indeed16:31
patrickphushell: do you have some ideas?16:31
@lisitsynpatrickp: NLP thing would be easier I guess?16:31
iglesiasglisitsyn, zeller, thanks for backing me up16:31
Chenglisitsyn: Yes, well to help if I can.16:31
patrickplisitsyn: ocr should be feasible too. just sequence16:31
@lisitsynpatrickp: allright good16:32
patrickpi'll talk to shell again about this16:33
@lisitsynyes, please think about some concrete app16:33
patrickpwill do16:33
@lisitsynthanks patrickp! hushell is away I guess :)16:33
@lisitsynCheng: foulwall: lets talk about your project then16:33
@lisitsynfirst of all, foulwall is the MVP for demos16:34
foulwalllisitsyn: :)16:34
@lisitsynso we are going to use his small framework16:34
@lisitsynto develop these demos16:34
@lisitsyn(I hope so!)16:34
@lisitsynother demos are to go still though but that's to be dicussed later16:35
@lisitsynas Cheng is here I'd like to check what we have on mldata integration16:35
@lisitsynCheng: foulwall can any of you talk on that a bit?16:36
@lisitsynping ;)16:36
foulwallCheng: Now I've worked out a simple interface on mldata16:37
ChengI have been a bit distracted recently. I sent a list of 6-7 datasets to the shogun list to start of the testing16:37
Chengfoulwall: Perhaps you need to summarize what you have done to date.16:37
foulwallCheng: Ok, I'm sorry for my distracted, for the finals...16:38
@lisitsynwe have foulwall a bit out of time with his exams so we'd have to get back to the schedule16:39
foulwallCheng, I'll check that email again and make a schedule out16:39
@lisitsynCheng: could you please tell us what is we are aiming to?16:39
@lisitsynwhat can we do once foulwall is done with integration16:40
@lisitsynvotjakovr: around?16:41
votjakovrlisitsyn: yep16:41
ChengThe idea is to write a data class in shogun to read (and write) mldata containers.16:41
@lisitsynvotjakovr: please prepare to be next ;)16:42
@lisitsynCheng: so we can just load any mldata dataset in oneliner, right?16:42
ChengOnce this is done, interaction with mldata.org's datasets should be much easier.16:42
votjakovrlisitsyn: Ok, just let me know when i need to start16:43
@lisitsynI am not sure it makes sense to speak about demos as foulwall's project is all about demos16:43
@lisitsyn:)16:43
@lisitsynCheng: do you have anything to note on the project?16:43
@lisitsynfoulwall: and you?16:43
foulwallnop16:43
@lisitsynalright16:45
@lisitsynvotjakovr: as Heiko is not here you have to talk on your own ;)16:45
votjakovrOk16:45
votjakovrAs you might know, my GSoC project is about implementing Gaussian Processes for Classification.16:45
@lisitsynCheng: sorry we have to hurry up a bit ;)16:46
@lisitsynthanks Cheng:16:46
votjakovrI had discussed the possible applications of GPC with HeikoS.16:46
votjakovrAnd we decided to make several classification (binary and multiclass) examples with nice real/toy datasets (2d and higher dimensional), which can show an advantages of using Gaussian Processes.16:46
votjakovrAnd also I planned to implement an interactive point-click demo.16:46
Chengnothing to note.16:46
votjakovrThese examples might be useful for people, who is unfamiliar with GPs.16:46
votjakovrAnd we might get a better results with GPC rather than SVMs in multiclass case :)16:47
@lisitsynvotjakovr: indeed if you have a lot of classes16:47
@lisitsynvotjakovr: alright so the demo is actually an improvement of the thing foulwall created16:48
@lisitsynhttp://shogun-toolbox.org/demos/gp/entrance16:48
votjakovrlisitsyn: yep, the idea was about implement all features of GPs in one demo16:49
@lisitsynyes that would be nice16:49
votjakovrlisitsyn: regression and classification16:49
@lisitsynokay I have not the best understanding of GPs so I am not sure I can comment something ;)16:50
@lisitsynthanks votjakovr16:50
@lisitsynvan51: around?16:50
van51lisitsyn: yeap16:50
van51lisitsyn: should I go next?16:50
@lisitsynvan51: yes please16:51
@lisitsynvan51: I know you didn't come up with anything concrete16:51
van51i will just give a gist of our ideas16:51
@lisitsynyeah sure16:51
van51so, for this GSoC I will implement two different but correlated techniques for learning on large scale data16:52
van51one is based on reducing the feature dimension using hashing16:52
van51the other approximates the feature space ( I think, I haven't looked into that one yet :P )16:52
van51and as for a demo/application16:53
van51we have been thinking of something web based as well, where the user could upload a piece of text or an image and it would classify it appropriately16:53
van51something like language detection or spam filter16:53
@lisitsynalright!16:54
@lisitsynthanks van5116:54
van51we haven't decided on the application domain yet, but that is what its infrastacture is going to be16:54
van51np :)16:54
@lisitsynvan51: yes, lets decide on the domain16:54
@lisitsynas I said lets choose something you like most16:54
@lisitsynokay so next is gsomix16:56
gsomixlisitsyn, ok16:56
@lisitsyngsomix: what can we consider as a demo of your project?16:56
gsomixso, this summer I'm working at readers and writers in various file formats. this is technical project.16:57
gsomixdemos are technical too.16:57
@lisitsynyeah16:57
@lisitsynso my idea would be is to show some graphs16:57
@lisitsynthat prove that readers are fast enough16:58
@lisitsynI agree there is no big room for demo-ing16:58
@lisitsynso lets go with some graphs16:58
@lisitsynalright thanks gsomix16:59
gsomixThis includes: benchmarks; converter from one format to other (like csv->matlab); some real-life demo like load data sets run some machine on it16:59
gsomixlisitsyn, yeah, graphs will be nice16:59
@lisitsynyes16:59
@lisitsynloading-saving seems to be a nice application17:00
@lisitsynlambday: here?17:00
lambdaylisitsyn: yes17:00
@lisitsynlambday: could you please finish then? :)17:00
lambdaysure :)17:00
lambdayalright, so, we have this huge Gaussian markov random field.. and the data is real (gathered from an orbiting satelite).. and we are trying to estimate parameters in this...17:01
lambdaythe likelihood expression contains a log determinant term of the precision matrix, which is massive (~10^6) and sparse.. and therefore becomes the bottleneck of estimating parameters..(because of massive memory requirement).. because the usual techniques fail..17:01
lambdaymy project is about approximating this log determinant of a matrix up to an arbitrary precision which can be computed on a normal computer with, say 4~8 GB ram.. and the approach relies on a number of techniques from numerical linear algebra and complex analysis..17:02
lambdayonce the project is ready, we have planned to work on this ozone example http://www.ucl.ac.uk/roulette/ozoneexample and estimate parameters..17:02
@lisitsynlambday: alright and this is going to be the demo17:03
@lisitsynright?17:03
iglesiasgit sounds very interesting lambday!17:04
lambdaylisitsyn: yep17:04
lambdayiglesiasg: yes :) I'm really excited to see this working17:04
@lisitsynlambday: alright, this is again some graphics so we could go for doing it with d3 too17:04
@lisitsynthanks lambday17:05
@lisitsynalright17:05
lambdaylisitsyn: we haven't decided anything on that yet.. I'll talk to Heiko regarding that :)17:05
@lisitsynthis was long! sorry if I took more time than expected17:05

@lisitsynand please don't forget about weekly reports17:07
@lisitsynplease send them each monday to the mailing list17:07
@lisitsynhas anyone got questions?17:07
lambdaylisitsyn: by monday, you mean as long as its still monday anywhere on earth, we're cool, right? :P17:08
@lisitsynlambday: heh well please send them rather monday morning17:08
@lisitsynor even sunday evening17:08
lambdaylisitsyn: alright :D haha17:09
@lisitsynas for next meeting17:09
@lisitsynlets schedule it a bit later17:09
@lisitsynlet iglesiasg send around a doodle and then we can schedule it17:10
