| josip | what would be the best way to attach my transcripts/cv to the application? | 00:59 |
|---|---|---|
| josip | I can provide dropbox links or e-mail them to .. someone | 00:59 |
| alesis-novik | your what? | 01:08 |
| alesis-novik | I guess there is the field for additional info | 01:08 |
| josip | but I don't feel very comfortable putting my transcripts online | 01:30 |

| alesis-novik | Why do you want to put a transcript? | 01:58 |
| alesis-novik | In cases like these I generally state what I did/have, and ask to be contacted if proof is required (but don't take my work for this being a good or bad idea, I'm just an applicant like you) | 02:00 |
| alesis-novik | So what idea are you applying for? | 02:02 |
| josip | the boosting-like algorithm for variable-dimensinaol features | 02:20 |
| josip | the last one on the list if that rings a bell | 02:20 |

| serialhex | not really :P | 06:29 |
| serialhex | bettyboo: whats up cutie? | 06:29 |
| @bettyboo | serialhex: btw, you said there is about ten proposals? | 06:29 |
| serialhex | bettyboo: no, many more than that | 06:29 |
| @bettyboo | serialhex: I mean, there are only so many good ML researchers with that kinda background who could do all of those problems, and then the number of students would be like, maybe 20 times that? I can't imagine there being more than 400 of us | 06:30 |
| serialhex | bettyboo: how many people propose to you? | 06:30 |
| @bettyboo | serialhex: what algorithms do you propose to implement? | 06:30 |
| @bettyboo | yes | 06:30 |
| serialhex | bettyboo: fie on you! fie fie fie! | 06:30 |
| @bettyboo | serialhex: nasty you!@ | 06:30 |
| serialhex | :P | 06:30 |
| @bettyboo | ;> | 06:30 |
| serialhex | bettyboo: you're my kind of girl!! | 06:31 |
| @bettyboo | serialhex: what was the train/test split, did you use 10cfv? how long did the training last, which kernel, what kind of feature data, binary, float, decimal, how long did the testing last ? | 06:31 |
| serialhex | bettyboo: the training lasted a long time! | 06:31 |
| @bettyboo | serialhex: are there any c# wrappers for it? the other, they report 10mil training samples,do you know how big was each sample (without going into those papers)? | 06:31 |

| siddharth | hi sonney2k | 17:33 |
| @bettyboo | moin. siddharth | 17:33 |
| siddharth | i have send the patch to the mailing list | 17:33 |
| Ziyuan | Is src/libshogun the same as src/shogun ? | 17:34 |
| siddharth | hi betty | 17:34 |
| @bettyboo | siddharth: ask to put a C -> F conversion module into betty | 17:34 |
| @bettyboo | ho siddharth | 17:34 |
| siddharth | haha...those were sonney2k words :D | 17:34 |
| @bettyboo | :> | 17:34 |
| @sonney2k | Ziyuan, it is a symlink yes | 17:34 |
| @sonney2k | siddharth, I am looking at your patch right now | 17:35 |
| @sonney2k | looks pretty good! | 17:35 |
| siddharth | ok :) | 17:35 |
| @sonney2k | minor whitespace issues | 17:35 |
| siddharth | yeah | 17:35 |
| @sonney2k | you mixed tabs with spaces | 17:35 |
| siddharth | i forgot to correct | 17:35 |
| @sonney2k | and missing newlines between functions but that is really all | 17:35 |
| @sonney2k | let me merge it | 17:35 |
| Ziyuan | Ah, symlink, thanks | 17:36 |
| siddharth | well I have done for matlab interface only | 17:36 |
| @sonney2k | siddharth, actually it says siddharth <siddharth@siddharth-laptop.(none)> | 17:36 |
| siddharth | will do for other too | 17:36 |
| @sonney2k | do you want to give reasonable email addr's? | 17:36 |
| siddharth | yes...new with git | 17:36 |
| siddharth | yes | 17:37 |
| siddharth | siddharthkherada27@gmail.com | 17:37 |
| * sonney2k just set up http://shogun-toolbox.org/trac | 17:37 | |
| @sonney2k | siddart you can use git config to set your username | 17:38 |
| @sonney2k | e.g. I have | 17:38 |
| @sonney2k | git config -l | 17:38 |
| @sonney2k | user.name=Soeren Sonnenburg | 17:38 |
| @sonney2k | user.email=sonne@debian.org | 17:38 |
| siddharth | ok I will do that | 17:38 |
| siddharth | thanks :) | 17:38 |
| @bettyboo | ;D | 17:39 |
| @sonney2k | siddharth: http://help.github.com/git-email-settings/ | 17:39 |
| @sonney2k | siddharth, would you mind to send the patch again when you have done this | 17:39 |
| @sonney2k | it is better that you type your name and email addr correctly | 17:40 |
| @sonney2k | I cannot change it afterwards | 17:40 |
| siddharth | sonney2k, can I send after the deadline? | 17:40 |
| @sonney2k | siddharth, ahh you are still writing on your proposal? | 17:40 |
| siddharth | yeah | 17:40 |
| @sonney2k | siddharth, just send it quickly to me personally - it really is just issuing | 17:41 |
| @sonney2k | $ git config --global user.name "Firstname Lastname"Sets the name of the user for all git instances on the system | 17:41 |
| @sonney2k | $ git config --global user.email "your_email@youremail.com" | 17:41 |
| @sonney2k | and git reformat-patch again | 17:41 |
| @sonney2k | that's it | 17:41 |
| siddharth | ok doing now | 17:41 |
| serialhex | wow, yeah, just from the people who are saying they've set up shogun theres a bunch!! | 17:47 |
| siddharth | sonney2k, should i send to you or the mailing list? | 17:51 |
| @sonney2k | serialhex, I was seriously only expecting 10-15 people... | 17:52 |
| @sonney2k | siddharth, to me is sufficient / but up to you | 17:52 |
| @sonney2k | now I am already scared of having to wade through all of them | 17:52 |
| serialhex | sonney2k: you have what? like 2 weeks to go through them?? you could turn around and ask Q's of the applicants can't you?? | 17:53 |
| serialhex | ...kind of like a job interview? (i mean, this kind of is) | 17:53 |
| siddharth | sonney2k, done :) | 17:54 |
| @bettyboo | :> | 17:54 |
| @sonney2k | serialhex, we have to reduce the number of potential candidates very quickly - it is totally impossible to interview >60 people | 17:54 |
| serialhex | very true, very true | 17:54 |
| @sonney2k | siddharth, thanks - very good. applying now | 17:54 |
| siddharth | sonney2k, there are 60 proposals or 60 students? :O | 17:55 |
| @sonney2k | siddharth, that also means I have to convince 10-15 potential mentors to go through all of them... | 17:55 |
| serialhex | ...is there anything i can do to help my application? | 17:55 |
| @sonney2k | serialhex, patches like siddharth sent... | 17:56 |
| siddharth | sonney2k, should I mention patch in proposal? | 17:56 |
| @sonney2k | siddharth, of course!!! | 17:56 |
| brocolli | heh | 17:56 |
| serialhex | sonney2k: ok, i'll see what i can find to do... | 17:56 |
| siddharth | ok :) | 17:56 |
| brocolli | I am going to be laughing if I get rejected because my name on irc isn't proper :/ | 17:56 |
| brocolli | or somethign like tha | 17:56 |
| Ziyuan | In center_matrix of Mathematics.h, matrix[int64_t(i)*m+j]+=s-colsums[i]-rowsums[j]; should be matrix[int64_t(i)*m+j]+=s-colsums[j]-rowsums[i]; | 17:56 |
| * serialhex looks for something a n00b can code :P | 17:57 | |
| Ziyuan | Right? | 17:57 |
| @sonney2k | serialhex, it is really >60 students and even more proposals... - it is crazy | 18:05 |
| @sonney2k | makes you proud and ashamed at the same time :( | 18:05 |
| brocolli | what | 18:06 |
| brocolli | how the hell | 18:06 |
| Ziyuan | Let me make a patch | 18:06 |
| brocolli | I don't believe there are that many machine learners out there sonney2k | 18:06 |
| brocolli | :/ | 18:06 |
| @sonney2k | brocolli, me neither - so lets hope half of them are not and stand corrected !? | 18:07 |
| brocolli | lol | 18:07 |
| brocolli | I mean, the only reaon I applied was to see if I got it + needed a job. Otherwise if I'm getting funded over the summer I'd rather work on other stuff ;p | 18:07 |
| @sonney2k | Ziyuan, could be - the matrix is supposedly square so I never checked | 18:08 |
| brocolli | But I don't know if I will be funded yet, hence my application ;) | 18:08 |
| brocolli | It's admirable people want to do ML, but it's more than just programming. GSoC == Funding but simultaneously encourages people to apply even if it's not their area of interst ;P | 18:09 |

| brocolli | Well I should know in a day or two | 18:13 |

| brocolli | I'll let you know the same day | 18:14 |

| eppz | they don't get paid for GSoC either | 18:32 |
| eppz | I think the organization receives just $500 | 18:32 |
| brocolli | But hte software is representing the institution | 18:33 |

| brocolli | You're missing the point man, that's all. | 18:36 |

| josip | deadline -0140 | 19:20 |
| josip | hehe | 19:20 |
| @bettyboo | hihi!! | 19:20 |
| josip | the melange editor is awful btw | 19:22 |
| Ziyuan | Can I update my proposal after the deadline? | 19:24 |
| josip | no | 19:30 |
| @sonney2k | brocolli, we are surely not doing this for money (actually we don't get any) | 19:38 |
| @sonney2k | for that | 19:38 |
| brocolli | not you | 19:39 |
| @sonney2k | I do it to get new contributors and be assured that I have to do all the real work while I am trying to mentor | 19:39 |
| @sonney2k | well none of the people in the shogun project | 19:39 |
| brocolli | Your institution is doing it because of the cutting edge nature of the project | 19:39 |
| brocolli | it's implementing really good algorithms into an open source piece of software, all on behalf of MPI | 19:39 |
| brocolli | It's good for the brand of the institution, I'm sure you cannot dispute that. | 19:39 |
| josip | it's a win-win situation, that's why they're doing it | 19:39 |
| @sonney2k | brocolli, the institution does not care - to the contrary they would rather want to see me do some real work (aka research) | 19:40 |
| josip | you're working at MPI Tuebingen? | 19:40 |
| brocolli | sonney2k: so what is the purpose of such a large undertaking? For fun | 19:40 |
| brocolli | I say this with the utmost respect | 19:41 |
| brocolli | I am just saying there are always hidden variables with large weight :P | 19:41 |
| @bettyboo | yeah | 19:41 |
| @sonney2k | brocolli, no idea.... look I am one of the initiators and still leading figure behind mloss.org / mldata.org | 19:42 |
| * brocolli doesn't know much about open source but has heard of mloss.org for sure | 19:42 | |
| @sonney2k | brocolli, well I wrote most of the website | 19:43 |
| josip | thanks for mloss! It has proven very helpful to me | 19:43 |
| @sonney2k | have a look at mldata.org too | 19:45 |
| josip | yu; | 19:45 |
| josip | p | 19:45 |
| @sonney2k | mldata.org is like 100 times more work :D | 19:45 |
| @bettyboo | yep | 19:45 |
| @sonney2k | anyway got to go | 19:45 |
| @sonney2k | cu | 19:45 |

| @sonney2k | ok, so we have exactly 70 proposals now | 21:59 |
| @sonney2k | by over 60 students | 22:00 |
| epps | congrats | 22:00 |
| @sonney2k | in #gsoc they say 417 mentoring orgs applied and 175 were accepted this year; 5474 proposals were submitted by 3731 students. | 22:00 |
| @sonney2k | which means on average an organization gets 20 students / or 31 applications | 22:01 |
| blackburn | really wonder how you will choose 5-10 from that 70 | 22:01 |
| * sonney2k does not know either :-( | 22:01 | |
| josip | sonney2k: I don't think the distribution is inoform :D | 22:01 |
| @bettyboo | ;D | 22:01 |
| @sonney2k | surely not | 22:01 |
| josip | e.g. there are a lot of people applying for wordpress and stuff liek that | 22:01 |
| blackburn | machine learning is in trending now | 22:01 |
| @sonney2k | looks like | 22:01 |
| blackburn | by some reason | 22:02 |
| josip | well, it started being widely applied? | 22:02 |
| josip | to almost everything? :) | 22:02 |
| @sonney2k | the problem is we are a new organization - it is not clear how much google will trust us to mentor more than 5 students | 22:02 |
| @bettyboo | yep :> | 22:02 |
| @sonney2k | (the gsoc orga faq says 5 students for new orgas at the max) | 22:03 |
| @sonney2k | anyways, we will do our best to get more... | 22:03 |
| josip | hehe, good luck with that :) | 22:03 |
| blackburn | sonney2k: 5 from 70? oh, I don't envy you | 22:03 |
| @sonney2k | lets hope for the best | 22:05 |
| -!- Mengyun [~Mengyun@S0106001a803d4363.vc.shawcable.net] has joined #shogun | 22:06 | |
| blackburn | sonney2k: when creating new kernel, where should I describe it (excluding its .cpp and .h and kernel type in Kernel.h)? | 22:07 |
| @sonney2k | well only in the doxygen doc in the .h and make an example | 22:08 |
| blackburn | I mean I created it and it doesn't importing | 22:08 |
| blackburn | okay, so think I did something wrong :) | 22:09 |
| siddharth | did you do make install? | 22:09 |
| blackburn | of course | 22:09 |
| siddharth | no error in that? | 22:09 |
| blackburn | nope | 22:09 |
| blackburn | oh | 22:09 |
| blackburn | I forget configure! | 22:09 |
| @sonney2k | blackburn, you mean for the modular interfaces or what? | 22:09 |
| siddharth | not needed | 22:09 |
| blackburn | sonney2k: yeap, python_modular | 22:10 |
| blackburn | sonney2k: siddharth's kernel is importing but my - not | 22:10 |
| siddharth | did u change in GUIkernel file? | 22:10 |
| @sonney2k | blackburn, open up modular/Kernel.i | 22:10 |
| blackburn | sonney2k: ah! that's it | 22:10 |
| blackburn | thank you | 22:10 |
| @sonney2k | then search for GaussianKernel and add the same 3 lines :) | 22:11 |
| blackburn | sonney2k: btw, my _proper_ patch is in ML | 22:11 |
| blackburn | I was terrified when looked what I sent to ML | 22:12 |
| blackburn | some trash generated by my eclipse, sorry :) | 22:12 |
| @bettyboo | ;D blackburn | 22:12 |
| @sonney2k | blackburn, don't worry. Always remember the ML'ers can't code so whatever we send looks great to 'them' | 22:12 |
| @sonney2k | ;-) | 22:12 |
| @bettyboo | funny | 22:12 |
| -!- akhil_ [75d35896@gateway/web/freenode/ip.117.211.88.150] has quit [Quit: Page closed] | 22:13 | |
| blackburn | I thought that Kernel.i is filled automatically.. | 22:14 |
| blackburn | Was I wrong? | 22:14 |
| @sonney2k | blackburn, that is not done automatically | 22:14 |
| blackburn | I see now | 22:14 |
| siddharth | for static interfaces you have to change in SGInterface and GUIKErnel file | 22:15 |
| @sonney2k | exactly. siddharth knows what he is talking about | 22:15 |
| blackburn | sonney2k: I should do this too, right? | 22:16 |
| * sonney2k hates the static interfaces though | 22:16 | |
| @sonney2k | but we started with them... | 22:16 |
| * siddharth loves matlab :D | 22:16 | |
| blackburn | >>> from shogun.Kernel import WaveKernel | 22:16 |
| blackburn | >>> wk = WaveKernel() | 22:16 |
| blackburn | thank you! | 22:16 |
| blackburn | works now | 22:16 |
| siddharth | nice | 22:16 |
| blackburn | will now write this stuff in SGInterface and etc | 22:17 |

| @sonney2k | blackburn, I think it would be a good idea that you send your kernel overview html page to the mailinglist - in case others would like to contribute a patch | 22:18 |
| blackburn | sorry, don't understand you properly, should I describe this kernel in html? | 22:19 |
| @sonney2k | I think it is the only way to reduce the number of applicants requiring some contribution ... | 22:19 |
| siddharth | sonney2k, me too? | 22:20 |
| @sonney2k | well you both already contributed | 22:20 |
| blackburn | i'm looking forward for further contributions :) | 22:20 |
| @bettyboo | lol! | 22:20 |
| siddharth | same here :) | 22:20 |
| @bettyboo | ;D | 22:21 |
| blackburn | so, when introducing new kernel I should send it with examples and description, right? | 22:21 |
| @sonney2k | blackburn, that would be perfect | 22:21 |
| blackburn | is it necessary to do it in html? | 22:21 |
| blackburn | I mean there is only one equation and nothing to describe detailly | 22:21 |
| * siddharth off to sleep...gn | 22:22 | |
| blackburn | sonney2k: anyway, I have no problem with doing this, may I ask you later about some details of it by email or in irc? | 22:23 |
| @sonney2k | blackburn, not html doxygen! | 22:23 |
| @sonney2k | look at gaussiankernel | 22:23 |
| blackburn | ah | 22:23 |
| blackburn | that's what you mean | 22:24 |
| blackburn | okay, I understand now | 22:24 |
| blackburn | do you want to reduce applicants-contributors? | 22:24 |
| blackburn | number of* I mean | 22:25 |
| @sonney2k | blackburn, please send the url of that paper to the mailinglist ... I will send an email around saying that we have so many submission and some of you asked how they could improve scores... by contributing a patch is my answer | 22:25 |
| blackburn | sorry, don't understand you again. what is the paper I should url? | 22:26 |
| blackburn | may be I'm tired a bit, sorry :) | 22:27 |
| @sonney2k | blackburn, the url with the kernels | 22:30 |
| @sonney2k | that is really an easy start learning to extend shogun | 22:30 |
| blackburn | http://crsouza.blogspot.com/2010/03/kernel-functions-for-machine-learning.html#wave | 22:30 |
| blackburn | this? | 22:30 |
| blackburn | with no '#wave' | 22:30 |
| @sonney2k | yes | 22:31 |
| blackburn | sonney2k: you will have a terrible count of commits :) | 22:31 |
| @sonney2k | blackburn, or maybe only from the 10 students we can then later on accept | 22:31 |
| @sonney2k | :) | 22:31 |
| @bettyboo | ;D | 22:31 |
| blackburn | what should you do if ~10 will commit you all the time.. :) | 22:32 |
| blackburn | sonney2k: will you go to sleep in nearest a half of hour? | 22:32 |
| blackburn | sonney2k: I could send a patch with WaveKernel with this link | 22:32 |
| @sonney2k | blackburn, just sent the patch in one email and then later on reply to my email with this link | 22:33 |
| @sonney2k | I am jsut writing it | 22:33 |
| @sonney2k | :) | 22:33 |
| blackburn | but why you want to me send this url? :) | 22:34 |
| blackburn | me to send* (oh, I have bad teachers of english) | 22:34 |
| blackburn | sonney2k: and again, what's with generalized HIK patch? did I done all the things right? | 22:35 |
| @sonney2k | blackburn, looked good but I need to have a closer look. | 22:35 |
| @sonney2k | will apply it probably today still. | 22:35 |
| blackburn | I have tested it this time :) | 22:36 |
| @bettyboo | rahaha | 22:36 |
| blackburn | that non-proper patch is pretty ugly diff of something I don't understand | 22:36 |
| blackburn | understand why you get angry with it :) | 22:36 |
| @bettyboo | blackburn, rahaha | 22:36 |
| @sonney2k | blackburn, you should really use github infrastructure | 22:37 |
| @sonney2k | I mean fork off shogun from git | 22:37 |
| @bettyboo | nite | 22:37 |
| @sonney2k | then modify your tree | 22:37 |
| @sonney2k | then submit a pull request | 22:37 |
| @sonney2k | that is coolest - but of course patches to the mailinglist are as welcome! | 22:37 |
| blackburn | okay, I will grasp with it | 22:38 |
| blackburn | it's because I'm novice in git | 22:38 |
| blackburn | that static interfaces in libshogunui.. I don't like it much :) | 22:40 |
| @sonney2k | blackburn, I hate them too | 22:40 |
| @sonney2k | they need a cleanup | 22:40 |
| @sonney2k | swig is soo much more elegant | 22:40 |
| blackburn | every kernel need it, right? | 22:40 |
| @sonney2k | in particular you touch the modular/*.i file once and you get interfaces to alll the languages. | 22:41 |
| blackburn | I mean should I do this? | 22:41 |
| blackburn | now* | 22:41 |
| blackburn | seems so :) | 22:41 |
| @sonney2k | you don't have to do static :) | 22:42 |
| blackburn | I don't?? | 22:42 |
| * sonney2k only uses the modular interfaces... | 22:42 | |
| @sonney2k | anyways | 22:42 |
| blackburn | may I sent a patch with only modular available? | 22:42 |
| @sonney2k | blackburn, sure | 22:42 |
| blackburn | okay | 22:42 |
| @sonney2k | ok, I've sent the email to the mailinglist | 22:42 |
| @sonney2k | I suggest you reply with this url - it is a good thing for students to pick one kernel and to implement it.... | 22:43 |
| blackburn | should I answer you with that link? | 22:43 |
| @sonney2k | yes | 22:43 |
| blackburn | okay | 22:43 |
| @sonney2k | the patch as a separate email please | 22:43 |
| blackburn | np | 22:43 |
| @sonney2k | thanks | 22:43 |
| blackburn | hope will not sink myself with that suggestion :) | 22:43 |
| @sonney2k | I have to leave now... | 22:44 |
| @sonney2k | will be back later | 22:44 |
| blackburn | okay | 22:44 |

| Mengyun | Hi sonney2k, is there any bug list for shogun available ? | 22:54 |
| @sonney2k | Mengyun, not really an up-to-date one - I've just set up http://shogun-toolbox.org/trac - and tried to free it from some spam | 23:16 |
| blackburn | sonney2k: I have introduced a new kernel, set up to modular, etc | 23:19 |
| blackburn | should patch include doxygen docs for it? | 23:19 |
| @sonney2k | blackburn, yes please | 23:19 |
| blackburn | I mean doxygen generates it by source | 23:19 |
| @sonney2k | it is not so difficult | 23:19 |
| @sonney2k | just look at the comments in gaussiankernel.h for example | 23:19 |
| @sonney2k | (only the .h file needs to be documented) | 23:20 |
| blackburn | i done all this way | 23:20 |
| blackburn | have done | 23:20 |
| blackburn | okay, will create docs for it | 23:20 |
| @sonney2k | blackburn, the doc will be autogenerated | 23:22 |
| blackburn | I mean it | 23:22 |
| @sonney2k | you can try to import your kernel form python and then do help(yourkernel) | 23:22 |
| @sonney2k | it should show the docs | 23:22 |
| @sonney2k | and the html site | 23:22 |
| blackburn | just need to reconfig, disabled docs with slow generation :) | 23:22 |
| @bettyboo | ;> | 23:23 |
| blackburn | that kernel is a bit strange.. will cause many NaN when K(x,y) and x==y | 23:24 |
| @sonney2k | doesn't sound right - maybe only for certain parameter settings? | 23:26 |
| blackburn | there is theta/||x-y|| | 23:27 |
| blackburn | x==y will cause theta/0 | 23:27 |
| @sonney2k | you have to check if that is the right thing | 23:27 |
| blackburn | I could better implement Cauchy kernel with no similar problems :D | 23:28 |
| blackburn | http://latex.codecogs.com/png.latex?k(x,%20y)%20=%20\frac{\theta}{\lVert%20x-y%20\rVert%20\right}%20\sin%20\frac{\lVert%20x-y%20\rVert%20}{\theta} | 23:29 |
| blackburn | that is wave kernel from link, I posted to ML | 23:29 |
| @sonney2k | blackburn, I suspect that when ||x-y|| == 0 that the kernel == 0 | 23:29 |
| @sonney2k | or 1 | 23:29 |
| @sonney2k | you have to check | 23:29 |
| blackburn | there is a link on that page to some dissertation.. and there is only mention of it | 23:31 |
| blackburn | with no Mercer prove or something else | 23:31 |
| blackburn | seems to be a very strange kernel | 23:31 |
| Mengyun | thanks sonney2k | 23:31 |
| blackburn | Limit[(h/x)*Sin[x/h], x -> 0] | 23:32 |
| blackburn | 1 | 23:32 |
| @sonney2k | blackburn, I think you could just replace sin(x) by its taylor expansion and then you will hopefully see what happens when ||x-y|| -> 0 | 23:32 |
| blackburn | I shouldn't could use that limit ^^ | 23:32 |
| blackburn | seems that 1 | 23:33 |
| @sonney2k | blackburn, I would expect that the value is 1.0 when x==y | 23:33 |
| blackburn | sonney2k: yeap, and with no respect to theta it is 1.0 | 23:33 |
| blackburn | if (dist==0.0) return 1.0; | 23:34 |
| blackburn | dirty :) | 23:34 |
| @sonney2k | blackburn, so just add a if statement and all good | 23:34 |
| blackburn | thank you | 23:35 |
| @sonney2k | Mengyun, what for? | 23:35 |
| blackburn | sonney2k: trac | 23:35 |
| @sonney2k | ahh yes | 23:36 |
| Mengyun | yep | 23:36 |
| * sonney2k looses trac(k) of everything | 23:36 | |
| Mengyun | :] | 23:36 |
| @sonney2k | Mengyun, the GSoC ideas in trac are from 2010 - we got rejected back then... | 23:37 |
| @bettyboo | hiho!! | 23:37 |
| * sonney2k what is going on with betty | 23:38 | |
| blackburn | sonney2k: | 23:39 |
| blackburn | Help on class WaveKernel in module shogun.Kernel: | 23:39 |
| blackburn | class WaveKernel(BaseKernel) | 23:39 |
| blackburn | | Wave kernel, formally described as \[ K(x,x') = | 23:39 |
| blackburn | | \frac{\theta}{\| x-y \|} \sin \frac{\| x-y | 23:39 |
| blackburn | | \|}{\theta} \]. | 23:39 |
| blackburn | | | 23:39 |
| blackburn | right? | 23:39 |
| blackburn | it is in python I mean :) | 23:40 |
| @sonney2k | yes | 23:40 |
| @sonney2k | the generated html code will look better | 23:40 |
| blackburn | I saw it | 23:40 |
| @sonney2k | I mean it is latex compiled | 23:40 |
| blackburn | should I send xml? | 23:40 |
| blackburn | oops | 23:41 |
| blackburn | not xml | 23:41 |
| @sonney2k | blackburn, ehh no, just the source code - the doxygen doc can be automatically generated | 23:41 |
| blackburn | should it be in doc? | 23:41 |
| @sonney2k | IIRC doc/html | 23:42 |
| blackburn | I see now | 23:43 |
| blackburn | seems that I should make it too | 23:43 |
