| RagnarX | Hello, world ! | 00:06 |
|---|---|---|
| n4nd0 | RagnarX: hi there! | 00:12 |
| RagnarX | n4nd0: how are you? :) | 00:13 |
| n4nd0 | RagnarX: I am fine, what about you? | 00:13 |
| RagnarX | I'm fine ! :D | 00:13 |
| RagnarX | I'm a student and I have an idea which is not in the idea page ^^' | 00:14 |
| n4nd0 | cool, I am a student too so I am not exactly the person you should propose it too | 00:14 |
| n4nd0 | but anyway, what is your idea about? maybe I can suggest you something ;) | 00:15 |
| RagnarX | It's about using OpenCL for Machine Learning :p | 00:15 |
| n4nd0 | ok | 00:16 |
| n4nd0 | I have no experience with OpenCL :( | 00:16 |
| RagnarX | yes it's kind of special :p | 00:16 |
| n4nd0 | I've heard of it of course, but nothing more than that | 00:17 |
| RagnarX | :p | 00:17 |
| RagnarX | where are you from? | 00:17 |
| n4nd0 | what do you think it could be used for in ml? | 00:17 |
| n4nd0 | I am from Spain, what about you? | 00:17 |
| RagnarX | France ^^ | 00:18 |
| RagnarX | to speed up machine learning :p | 00:18 |
| RagnarX | I am a developer for a linear algebra library on OpenCL and started a MultiLayer Perceptron project using OpenCL, and from the test i did there was nice speed improvements | 00:18 |
| n4nd0 | we use blas in shogun for linear algebra stuff | 00:19 |
| n4nd0 | do you have any idea aobout comparisons between linear algebra done on OpenCL and blas? | 00:20 |
| RagnarX | It mostly depends on the hardware :p but it is about 10 to 15 folds | 00:20 |
| RagnarX | http://viennacl.sourceforge.net/viennacl-benchmarks.html | 00:21 |
| RagnarX | I think the CPU benchmarks were done using blas | 00:21 |
| n4nd0 | oh it looks like really good performance then | 00:22 |
| RagnarX | yes :p | 00:23 |
| RagnarX | are you a shogun developer? | 00:23 |
| n4nd0 | I have done some contributions | 00:24 |
| RagnarX | I see ^^ | 00:25 |
| RagnarX | it looks like a cool project | 00:25 |
| n4nd0 | :) yes I think it is indeed | 00:25 |
| RagnarX | and gsoc always bring a lot of new developers | 00:27 |
| RagnarX | :p | 00:27 |
| n4nd0 | haha of course | 00:27 |
| n4nd0 | so I think that you could try asking soeren about your idea | 00:32 |
| n4nd0 | he is normally around here so he may answer you at any moment | 00:33 |
| RagnarX | Haha okay :p | 00:33 |
| RagnarX | isn't he sleeping right now? | 00:33 |
| RagnarX | Well maybe he's not an European :p | 00:34 |
| n4nd0 | oh sorry, I meant maybe not precisely now but if you come around tomorrow or sth like that | 00:35 |
| RagnarX | Yes I probably will :) | 00:35 |
| n4nd0 | in any case, you might want to use email | 00:35 |
| RagnarX | Yes, I've just registered to the mailing list :p | 00:37 |
| n4nd0 | good | 00:38 |
| RagnarX | i've also cloned the repository, but it is kinda big :p | 00:40 |
| n4nd0 | lot of work into there! | 00:41 |
| n4nd0 | :) | 00:41 |
| RagnarX | yep | 00:42 |
| RagnarX | :p | 00:42 |
| RagnarX | I think i'll send a mail on the list to describe my idea ^^ | 00:49 |
| n4nd0 | that's probably a good idea | 00:53 |

| n4nd0 | RagnarX: I have just made a quick search in the chat logs and found that at least they have commented the OpenCL topic a couple of times | 01:31 |
| n4nd0 | RagnarX: maybe you want to check about it | 01:31 |
| RagnarX | haha okay | 01:40 |
| RagnarX | I think i'll firstly go to bed :p | 01:40 |
| RagnarX | I have sent the mail today, and will probably read the logs tomorrow :p | 01:40 |
| RagnarX | when was it? | 01:40 |
| n4nd0 | google it | 01:51 |
| n4nd0 | opencl site:shogun-toolbox.org/irclogs will tell you about it ;) | 01:52 |

| aang | Is there any qualification task? | 11:15 |
| n4nd0 | great, do you have any idea in mind? | 11:15 |
| aang | I am familiar with the machine learning algorithms | 11:16 |
| aang | and i wish to contribute in your idea of Integrating Existing and Implementing New Machine Learning Algorithms in shogun | 11:16 |
| n4nd0 | aang: with qualification you mean something like a contribution to do before applying to GSoC? | 11:17 |
| aang | Yes. | 11:17 |
| n4nd0 | aang: I think that the page will be updated soon with info about that | 11:17 |
| aang | Ok. | 11:18 |

| varagrawal | Hey! | 13:08 |
| varagrawal | I am a student of Computer Science and Engineering from National Institute of Tech, Surat, INdia | 13:09 |
| -!- vikram360 [~vikram360@117.192.179.129] has joined #shogun | 13:09 | |
| varagrawal | I wanted to join in the Shogun toolkit Open source project | 13:09 |
| varagrawal | I have read your list of ideas page for GSoC 2012 | 13:10 |
| n4nd0 | hi | 13:10 |
| varagrawal | and being an undergrad with some basic knowledge of Machine Learning | 13:10 |
| n4nd0 | varagrawal: good, what idea did you find appealing? | 13:11 |
| varagrawal | I was thinking I could help with either Olivier Chapelles fast newton based SVM solver | 13:11 |
| n4nd0 | ok | 13:13 |
| n4nd0 | do you have experience with shogun? I mean if you have used it before | 13:13 |
| wiking | n4nd0: :> you should be a mentor ;) | 13:14 |
| n4nd0 | wiking: haha I don't think so :) | 13:15 |
| wiking | well u are all the time guiding possible gsocers here, so why not ;P | 13:15 |

| varagrawal | Hey | 13:16 |
| wiking | hihi | 13:16 |
| varagrawal | sorry | 13:16 |
| n4nd0 | but it is good to help people | 13:16 |
| n4nd0 | varagrawal: np | 13:16 |
| varagrawal | net got disconnected | 13:16 |
| varagrawal | the other idea was the implementation of Gaussian processes and regression techniques | 13:17 |
| n4nd0 | varagrawal: cool, those ideas look nice | 13:17 |
| n4nd0 | varagrawal: so have you used shogun before for sth? | 13:17 |
| varagrawal | I haven't used shogun, but I have used octave | 13:18 |
| wiking | varagrawal: it'd be nice that u start something with shogun before trying to apply for a gsoc project ... | 13:18 |
| varagrawal | I am starting to port those octave codes to shogun and try and achieve similar functionality | 13:18 |
| wiking | so at least check out the latest code | 13:18 |
| n4nd0 | exactly | 13:18 |
| wiking | and try to implement something in it | 13:18 |
| n4nd0 | varagrawal: have you already forked the repo? | 13:19 |
| wiking | since you'll have do most of the work in c/c++ | 13:19 |
| varagrawal | Yeah, I have a DBMS project, where I try to guess a good branch of study for a person | 13:19 |
| varagrawal | depending on their rank in the entrance exam | 13:19 |
| varagrawal | I was thinking of using Shogun for that with the KNN algo most probably | 13:19 |
| n4nd0 | ok | 13:20 |
| varagrawal | I will check out the code now | 13:20 |
| n4nd0 | but you might want you check out shogun code from the repo | 13:20 |
| varagrawal | Yes | 13:21 |
| varagrawal | Am cloning it now.. | 13:21 |
| n4nd0 | cool | 13:21 |
| n4nd0 | so maybe it is a good idea to try out some of the examples and get used to the structure of the project | 13:22 |
| varagrawal | aww net went again.... | 13:22 |
| varagrawal | I'll do that | 13:22 |
| n4nd0 | :) | 13:22 |
| varagrawal | Ok, thanks a lot for the suggestions :D | 13:22 |
| n4nd0 | varagrawal: you're welcome | 13:23 |
| varagrawal | I'll sit now and get back to you guys tomorrow morning fine? | 13:23 |
| n4nd0 | sure | 13:23 |

| wiking | blackburn: yoyo man | 16:06 |
| wiking | blackburn: your fucking email made a mess here in the channel :))) | 16:06 |
| n4nd0 | haha :) | 16:07 |
| blackburn | wiking: which one? | 16:07 |
| wiking | blackburn: gsoc...now there's heaps of people coming to talk about various gsoc projects ;) | 16:08 |
| blackburn | oh well we can't keep it in secret | 16:08 |
| wiking | :P | 16:08 |
| n4nd0 | so what do you think guys about the number of slots? | 16:11 |
| n4nd0 | is it likely to get those 9 you talked about yesterday? | 16:11 |
| wiking | it's amazing that VLC did not get a spot in gsoc this year :( | 16:12 |
| n4nd0 | I didn't know about that | 16:12 |
| n4nd0 | is there also a list of rejected orgs? | 16:13 |
| wiking | i don't think so | 16:13 |
| wiking | i've just seen it in twitter | 16:13 |
| n4nd0 | ok | 16:13 |
| n4nd0 | think of it this way ... we are contributing to sth more important than VLC :P | 16:14 |
| wiking | comeoooon | 16:15 |
| wiking | vlc is essential we can all agree | 16:15 |
| n4nd0 | haha just kidding | 16:15 |
| n4nd0 | different projects indeed | 16:16 |
| n4nd0 | wiking: about this deep learning, is it very good? | 16:19 |
| wiking | yep | 16:20 |
| n4nd0 | what is the main idea with it? | 16:20 |
| wiking | since it's unsupervised | 16:20 |
| wiking | and get's very good results | 16:20 |
| wiking | well it's a neural net | 16:20 |
| n4nd0 | ok | 16:20 |
| n4nd0 | I've used neural nets in supervised learning but nothing further than that | 16:21 |
| n4nd0 | it is always cool to hear from new stuff | 16:21 |
| wiking | well the mentioned theano toolbox is good enough | 16:21 |
| wiking | it even has cuda backend... | 16:21 |
| blackburn | I think we can get 7-8 at least | 16:24 |
| blackburn | cause we have reached success with 5 slots | 16:25 |
| blackburn | but 9 would be wonderful | 16:25 |
| n4nd0 | let's keep fingers crossed | 16:27 |
| n4nd0 | is that also announced as well? | 16:27 |
| n4nd0 | or just when applications are submitted and the students are notified? | 16:28 |
| blackburn | we will be notified how many slots we have got a little bit later | 16:54 |

| gsomix | puffin444, hi | 18:03 |
| puffin444 | Hey, I'm a student interested in the Gaussian regression project for the GSoC. | 18:04 |
| puffin444 | Do you know if the mentor (Stegle) hangs out on IRC, or should I try contacting him via email? | 18:05 |

| n4nd0 | puffin444: I may be wrong but I think that I have not seen him around here | 18:10 |
| gsomix | puffin444, i think, in this case, email is better than chat. | 18:12 |
| blackburn | puffin444: these guys are right, please contact him by email | 18:18 |
| puffin444 | Okay. I'll try to contact him via email. Would it help my case if I tried to fix a minor bug in Shogun? | 18:19 |
| blackburn | puffin444: any contributions are encouraged and would be an advantage | 18:22 |

| PhilTillet | Hello hello | 22:59 |
| blackburn | hi | 23:03 |
| PhilTillet | I have seen that it was necessary to submit a little pull request for Shogun ... :p How "small" does it have to be? | 23:12 |
| blackburn | PhilTillet: well.. | 23:17 |
| blackburn | it is not about size I think | 23:17 |
| PhilTillet | The other problem is that I don't really understand the "Issues" section on the github, to be honest | 23:18 |
| blackburn | it is not highly relevant, it is ok | 23:18 |
| blackburn | I've got not much time to keep it updated | 23:18 |
| PhilTillet | oh ok :p | 23:19 |
| PhilTillet | So i should rather browse code and see "what i can do" ? :p | 23:19 |
| blackburn | yeah rather do that | 23:19 |
| blackburn | or ask me/soeren | 23:19 |
| PhilTillet | okay :p | 23:19 |
| PhilTillet | Yes, the source code is rather big. I think i wouldn't be against having some pointers | 23:20 |
| blackburn | do you know any kernel that is not implemented in shogun? | 23:21 |
| PhilTillet | Well, my field is more Neural Networks / Optimization than SVM | 23:22 |
| PhilTillet | According to the website, conjugate gradient is not implemented, if I remember well | 23:22 |
| PhilTillet | And BFGS either | 23:23 |
| blackburn | well it could turn as a lot of work? | 23:25 |
| PhilTillet | Hmmm, well. It is something I have already done in C++ (even though I think my L-BFGS was buggy :p) ; it mostly depends on, well, how to interface it | 23:26 |
| PhilTillet | concretely, what should be minimized | 23:27 |
| PhilTillet | if it is just a functor which can return the value of a function and a gradient, it shouldn't be long | 23:28 |
| blackburn | can't you adapt it for some svm? | 23:28 |
| PhilTillet | Hmmm | 23:30 |
| PhilTillet | I think i would need to put myself up to date with SVM, but I could try | 23:31 |
| blackburn | I still do not know even my opinion on implementing something NN here | 23:31 |
| PhilTillet | well, it's true that SVM are very efficient, and most of the time better than NN | 23:32 |
| PhilTillet | well at least MLP | 23:32 |
| blackburn | it is not about efficiency - we've got a pretty long list of ideas | 23:34 |
| PhilTillet | And i think it would be indeed hard to implement CG ... I mean i'd have to first review all the architecture of SVMs in Shogun ... hmm ... | 23:34 |
| blackburn | then no need to do that | 23:34 |
| blackburn | our req about small patch is just a kind of a 'filter' | 23:35 |
| blackburn | cause we are probably going to receive >50 (~70 last year) proposals | 23:35 |
| PhilTillet | Got it :) | 23:36 |
| blackburn | at least it makes things more fair | 23:36 |
| PhilTillet | Well as far as I know Shogun implements linear, gaussian, sigmoid kernel | 23:36 |
| blackburn | i.e. chances we pick some student who just wrote good proposal and too lame with any development are pretty low then | 23:37 |
| blackburn | uh | 23:37 |
| PhilTillet | (and others) | 23:37 |
| blackburn | we have pretty many kernels here | 23:37 |
| PhilTillet | I know :p | 23:37 |
| PhilTillet | Wanted to tell that these 3 are the only kernels I know | 23:37 |
| blackburn | ah | 23:37 |
| blackburn | btw why do you want to work only on OpenCL? | 23:38 |
| PhilTillet | well, I don't want to work only on OpenCL | 23:38 |
| blackburn | did you found any other ideas interesting? | 23:39 |
| blackburn | as I said before we don't mind anything related to such things but we are pretty tight with slots | 23:39 |
| PhilTillet | the point is that I have "a lot" of experience using OpenCL because I have already done some projects on it and quite a bit of Linear Algebra on it too, and as of now no machine learning library use OpenCL so ... :) but the "Built generic multiclass learning framework" idea seems cool too | 23:41 |
| blackburn | aha I see | 23:41 |
| blackburn | ok I just got how can we solve it | 23:42 |
| blackburn | while you have a lot of experience with OpenCL you may help us with some basic operations here | 23:42 |
| blackburn | like dot product etc | 23:42 |
| PhilTillet | yep | 23:42 |
| blackburn | but mainly you may work on something different | 23:42 |
| PhilTillet | I see :p | 23:42 |
| blackburn | this is the case if we won't receive much slots | 23:43 |
| PhilTillet | Well, the point is that i'm also a contributor to an OpenCL linear algebra library | 23:43 |
| PhilTillet | which already implements dot product ... | 23:43 |
| blackburn | then probably it won't take much time for you | 23:43 |
| PhilTillet | yes, hope so :) | 23:44 |
| PhilTillet | but why not using already existing code? | 23:44 |
| blackburn | I did not say you can't use that code ;) | 23:44 |
| PhilTillet | haha :p | 23:44 |
| blackburn | depends on license though | 23:44 |
| PhilTillet | is MIT license okay? | 23:45 |
| blackburn | probably | 23:46 |
| blackburn | iirc we can integrate mit code in gpl project | 23:46 |
| PhilTillet | yes I think too, just have to be careful about how to integrate the license | 23:48 |
| PhilTillet | I'll ask to the project leader of that library :) | 23:50 |
| blackburn | sure | 23:50 |
| PhilTillet | well, to get back to that generic multiclass learning framework | 23:51 |
| PhilTillet | would it be about making some generic code that would map any binary classifier to multiclass ? | 23:52 |
| blackburn | there is such code already done by me recently | 23:52 |
| blackburn | probably main thing here would be to implement ECOC and some tree learning stuff | 23:53 |
| PhilTillet | I see | 23:55 |
| PhilTillet | there seems to be already a paper and some matlab code | 23:55 |
| blackburn | yes | 23:56 |
| PhilTillet | This will involve some generic programming right? | 23:56 |
