| Asix3 | Hi! I'm going to try an get an application together for GSOC. I'm wondering if there's any way to search the shogun mailing list | 01:54 |
| Asix3 | I've subscribed already, but I'm not sure if there's an archive of past messages | 01:54 |
| Asix3 | ...and I just found it. Nevermind! | 01:56 |
| shogun-buildbot | build #325 of nightly_none is complete: Failure [failed compile] Build details are at http://www.shogun-toolbox.org/buildbot/builders/nightly_none/builds/325 | 03:03 |
| alibezz | lisitsyn: hey, when you specified on step 7 "Add a class CSammonMapping that calls the tapkee library code for sammon mapping (check PR #1015 for example).Add a class CSammonMapping that calls the tapkee library code for sammon mapping (check PR #1015 for example)." | 03:35 |
| alibezz | lisitsyn: you mean a class in src/shogun/converter, right? i'm assuming so as of now | 03:36 |
| alibezz | =) | 03:36 |

| Asix3 | ok, I've forked shogun from git and cloned it to my system. I've ran ./configure, but 'make' isn't doing anything | 04:17 |
| Asix3 | well, it's giving me: make: *** No rule to make target '.config'. Stop. | 04:20 |
| Asix3 | ...and it looks like I figured that problem out, too -- sorry! | 04:34 |

| hushell | Hello guys I am Shell | 11:03 |
| hushell | Hi Sergey I see your reply I come here before going to bed | 11:04 |
| @lisitsyn | hushell: hey | 11:04 |
| @lisitsyn | HeikoS: nice to see you here | 11:04 |
| @lisitsyn | oops | 11:04 |
| @lisitsyn | :D | 11:05 |
| @lisitsyn | ok nice to see you both here | 11:05 |
| @lisitsyn | hah | 11:05 |
| hushell | nice to meet you guys | 11:05 |
| @lisitsyn | hushell: alright just hang there when you are available | 11:06 |
| hushell | I have a short question regarding the Binarylabels::score_to_probabilities() | 11:06 |
| @lisitsyn | although you are in a totally different timezone | 11:06 |
| @lisitsyn | hushell: what is the question? | 11:06 |
| hushell | yeah I am in UtC-8 | 11:07 |
| @lisitsyn | haha 12 hours between us | 11:07 |
| hushell | why this function doesn't output anything expect changing the confidences | 11:08 |
| @HeikoS | lisitsyn: Hi! | 11:08 |
| @lisitsyn | HeikoS: ^ could you please answer? | 11:08 |
| @HeikoS | hushell: why should it? | 11:09 |
| @HeikoS | the labels have a vector for the scores and one for the confidences | 11:09 |
| @HeikoS | this translates scores to confidences | 11:09 |
| @HeikoS | why should it do something else? | 11:09 |
| @lisitsyn | have to go now | 11:10 |
| hushell | Could you take a look at Eq.(7) in this paper: http://hal.archives-ouvertes.fr/docs/00/10/39/55/PDF/cr102875872670.pdf | 11:11 |
| hushell | it needs the learned parameters | 11:11 |
| hushell | I don't know much about Platt's rescoring, it seems like a calibration | 11:12 |
| hushell | using a sigmoid function | 11:13 |
| @HeikoS | looking ... | 11:13 |
| @HeikoS | hushell: I see | 11:14 |
| @HeikoS | you need the A and B | 11:14 |
| @HeikoS | let me quickly check the code | 11:14 |
| hushell | exactly | 11:15 |
| @HeikoS | ok, my suggestion then is: | 11:15 |
| @HeikoS | to put the sigmoid fitting method into CStatistics | 11:15 |
| @HeikoS | as fit_sigmoid(SGVector<float64_t>) | 11:16 |
| @HeikoS | this method returns A and B | 11:16 |
| @HeikoS | and is called from the binary labels | 11:16 |
| @HeikoS | hushell: what do you think of this? | 11:16 |
| hushell | Where is the CStatistics? | 11:17 |
| hushell | So you mean do it in another way | 11:17 |
| @HeikoS | hushell: no just make it modular | 11:18 |
| @HeikoS | or wait | 11:18 |
| hushell | Ok I found it | 11:18 |
| hushell | documentation is great! | 11:18 |
| @HeikoS | since you need the scores *and* the parameters | 11:18 |
| @HeikoS | and sigmoid fitting is not likely to happen somewhere else | 11:18 |
| @HeikoS | maybe put it into the scores_to_probabilities method | 11:19 |
| @HeikoS | dont really know whats best | 11:19 |
| @HeikoS | what do you think? | 11:19 |
| hushell | could you explain a bit how the scores_to_probabilities being implemented? | 11:21 |
| hushell | what's the target to fit? | 11:21 |
| hushell | sorry I haven't read this piece of code | 11:22 |
| @HeikoS | no worries | 11:22 |
| @HeikoS | it does two things: 1) fit a sigmoid via newton search, result is parameters a and b. 2) uses this sigmoid to compute all the probabilities given the scores | 11:22 |
| @HeikoS | code is taken from a paper btw | 11:22 |
| @HeikoS | have a look at the last lines of the method | 11:23 |
| @HeikoS | there are the important parts | 11:23 |
| @HeikoS | and also a and b | 11:23 |
| hushell | the algorithm is very clear | 11:26 |
| hushell | so why not just store the a and b | 11:26 |
| @HeikoS | not sure about this | 11:26 |
| @HeikoS | scores might change | 11:26 |
| @HeikoS | and without calling the method again they outdate | 11:26 |
| @HeikoS | maybe make a and b optional parameters | 11:27 |
| @HeikoS | if they are provided, they are not coimputed | 11:27 |
| @HeikoS | via method in CStatistics | 11:27 |
| @HeikoS | but you can also precompute yourself and then pass them | 11:27 |
| hushell | that's true it's being call during testing | 11:27 |
| @HeikoS | I think thats good | 11:27 |
| @HeikoS | do you want to move the code or should I do it? | 11:28 |
| -!- poojits [75d35d4a@gateway/web/freenode/ip.117.211.93.74] has joined #shogun | 11:28 | |
| hushell | I am not very clear how to do it | 11:29 |
| @HeikoS | hushell: dont worry | 11:29 |
| hushell | Seems a good chance to learn | 11:29 |
| @HeikoS | I will do it now, give me 10 mins | 11:29 |
| hushell | which function should I call from CStatistics | 11:30 |
| @HeikoS | you already have lots of stuff in your PR, lets not make it even more complex :) | 11:30 |
| @HeikoS | I will tell you in a bit | 11:30 |
| hushell | Okay let's see how you make it :) | 11:30 |
| hushell | Thanks so much. That's true, many files are involved | 11:31 |
| hushell | It | 11:31 |
| hushell | It | 11:31 |
| hushell | It's my first time to code in such a regular way | 11:31 |
| hushell | I just went through the code, it looks like the targets come from the counting of positives and negatives | 11:37 |

| @HeikoS | hushell: ok good night! | 12:10 |

| @HeikoS | there you will see how you can use CStatistics to get the sigmoid parameters | 12:11 |

| alibezz | iglesiasg: i started the implementation of the Sammon mapping. things are going a little slow because of my other tasks, but they're indeed evolving!... hehe i'm sort of basing my implementation on the IsoMap one | 14:31 |
| alibezz | like, seeing how the methods generally work in the lib etc | 14:31 |

| alibezz | iglesiasg: an for step 7 of my issue https://github.com/shogun-toolbox/shogun/issues/1025 | 14:33 |
| @iglesiasg | alibezz: are you using sammong mapping's code from the matlab toolbox for DR? | 14:33 |
| alibezz | i'm writing the class under converter. is it the right thing to do? | 14:33 |
| alibezz | yes i am. i still have some doubts on how to test my implementation | 14:34 |
| alibezz | should i write a little program or does shogun have some prototypes for isomap for example, and so i can easily modify it? | 14:34 |

| @iglesiasg | alibezz: so it can be done with a class in converter | 15:41 |
| @iglesiasg | alibezz: however, the DR in shogun is provided via tapkee | 15:41 |
| @iglesiasg | so implementing sammon mapping in tapkee directly would be a better choice | 15:41 |

| alibezz | iglesiasg: but it's gonna take me a while to have it all done. I have to prepare some lectures... hahahahha | 16:04 |
| @iglesiasg | hehe I see. No worries | 16:05 |
| alibezz | iglesiasg: the idea of sammon mapping is interesting though | 16:05 |
| @iglesiasg | alibezz: aham! I don't really know about it | 16:05 |
| @iglesiasg | alibezz: so it tries to minimize the error in the distance between input and projected space I read | 16:07 |
| alibezz | iglesiasg: yup. I'm going to implement using gradient descent, just like in the matlab code. | 16:08 |
| alibezz | iglesiasg: but maybe sgd would perform better. it's something to test in the future | 16:08 |
| alibezz | iglesiasg: how can i test my code? should i write a little program or do they have something for isomap that i can reuse? | 16:08 |
| @iglesiasg | alibezz: maybe one of the examples under examples/undocumented? | 16:09 |
| @iglesiasg | alibezz: or even any of tapkee examples | 16:09 |
| alibezz | iglesiasg: chill! didn't check these folders yet. ha | 16:09 |
| @lisitsyn | kind of re | 16:10 |
| @lisitsyn | alibezz: oh the idea of sammon mapping is as old as my parents probably :D | 16:11 |
| @iglesiasg | lisitsyn: around 1969 according to wikipedia | 16:11 |
| @iglesiasg | good number btw | 16:11 |
| @lisitsyn | a little younger then | 16:11 |
| @lisitsyn | the sammon mapping is I mean | 16:12 |
| alibezz | lisitsyn: iglesiasg: well my parents are def older. i'm 25. hehe they're from the 50s | 16:16 |
| @lisitsyn | alibezz: 22 and 1961 here | 16:16 |
| alibezz | lisitsyn: you guys are rather young! when did you start coding? | 16:17 |
| @lisitsyn | alibezz: as professionals or? | 16:18 |
| @iglesiasg | alibezz: I am 23 and started at university 5 years ago | 16:18 |
| @iglesiasg | haha but I am no professional :) | 16:18 |
| @iglesiasg | 5 years ago with pascal omg | 16:18 |
| @lisitsyn | I've been paid for programming for ehmm somewhere 1.5 to 2 years so far | 16:19 |
| alibezz | lisitsyn: weren't you coding before that? | 16:20 |
| @lisitsyn | alibezz: of course, for some more years | 16:20 |
| @lisitsyn | from school may be | 16:20 |
| alibezz | got it | 16:20 |
| alibezz | cool | 16:20 |
| alibezz | i started coding when i was 17 | 16:21 |
| @lisitsyn | >5 probably | 16:21 |
| @iglesiasg | ooh you are old hardcore programmers :P | 16:21 |
| alibezz | but mostly in research projects | 16:21 |
| @lisitsyn | I remember I was coding some puzzles when I was 11 | 16:21 |
| @lisitsyn | with pascal | 16:21 |
| alibezz | hahaha i don't have that much of experience in c++ tho | 16:21 |
| @iglesiasg | lisitsyn: oh that's super cool | 16:21 |
| @iglesiasg | lisitsyn: I regret none taught me anything about programming when I was younger | 16:22 |
| alibezz | yea same here | 16:22 |
| @iglesiasg | I didn't even know it existed before I started uni lol | 16:22 |
| alibezz | i wish i've learnt it earlier | 16:22 |
| alibezz | i spent most of my life studying french and english. ha | 16:22 |
| @iglesiasg | oh la al | 16:23 |
| @iglesiasg | oh la la hehe | 16:23 |
| alibezz | yea my life was kinda crazy. I like programming but I wish I knew C++ better. hhehhe well, it's all good | 16:24 |
| alibezz | living is learning lolz | 16:24 |
| votjakovr | living is machine learning :) | 16:26 |
| alibezz | votjakovr: i see what you did there! hahahaha def sounds like a slogan | 16:27 |

| cameron__ | hi | 17:47 |
| @iglesiasg | hi cameron__ | 17:50 |
| cameron__ | I'm trying to understand all the python tests work | 17:51 |
| cameron__ | I have found the directory where you keep all your test data in the tests/integration/tests | 17:51 |
| cameron__ | I'm wondering how are those files produced | 17:52 |
| @iglesiasg | cameron__: they are in the data submodule | 17:55 |
| @iglesiasg | another repository | 17:55 |
| cameron__ | i am reading the generate_testdata.py file in /tests/integration | 17:56 |
| cameron__ | if I run this, it will regenrate all the test data files | 17:56 |
| alibezz | iglesiasg: could you please tell me where the tapkee examples are? | 18:00 |
| alibezz | iglesiasg: the undocumented ones don't really have much to do with isomap (or any other of the implemented mappings) | 18:01 |
| @iglesiasg | alibezz: really? | 18:01 |
| @iglesiasg | let me check | 18:01 |
| alibezz | iglesiasg: seems so | 18:01 |
| @iglesiasg | alibezz: what about | 18:02 |
| @iglesiasg | https://github.com/shogun-toolbox/shogun/blob/master/examples/undocumented/libshogun/converter_isomap.cpp | 18:02 |
| alibezz | oh in libshogun? duh | 18:02 |
| alibezz | iglesiasg: i was looking for something in the python directories dunno why | 18:02 |
| @iglesiasg | alibezz: aham ok | 18:03 |
| alibezz | iglesiasg: sorry for that. and thanks ;) | 18:03 |
| @iglesiasg | alibezz: no problem ;) | 18:03 |
| @iglesiasg | there should be another example for isomap in python_modular or so in any case | 18:03 |
| alibezz | not really to be honest. or i'm crazy. | 18:03 |
| alibezz | because this is one of the dirs i checked out :O | 18:03 |
| @iglesiasg | https://github.com/shogun-toolbox/shogun/blob/master/examples/undocumented/python_modular/converter_isomap_modular.py | 18:04 |
| @iglesiasg | ? | 18:04 |
| @iglesiasg | alibezz: maybe you checked static interfaces | 18:04 |
| alibezz | iglesiasg: yeah maybe. or maybe i' m really crazy. there's always a possibility lolz | 18:09 |
| @iglesiasg | heh | 18:10 |

| cameron__ | iglesiasg: just by ./generator_testdata.py | 18:28 |
| @iglesiasg | cameron__: so did you modify anyting to add a new classifier or sth? | 18:29 |
| @iglesiasg | cameron__: dummy question -- have you compiled and installed for python_modular? | 18:31 |
| cameron__ | iglesiasg: yes, i've been playing around with shogun in python | 18:32 |
| cameron__ | iglesiasg: nvm, i'll try and figure it out myself. should just be sth minor | 18:32 |
| @iglesiasg | cameron__: ok | 18:33 |
| @iglesiasg | cameron__: I cannot test right now in my machine if it works, but I'd bet it should | 18:33 |

| alibezz | lisitsyn: ping | 19:30 |
| @lisitsyn | alibezz: pong | 19:31 |
| alibezz | lisitsyn: I'm trying to run the converter_isomap_modular.py example | 19:31 |
| alibezz | and it gives me this error: IOError: [Errno 2] No such file or directory: '../data/fm_train_real.dat' | 19:31 |
| alibezz | although i downloaded the data | 19:31 |
| @lisitsyn | how? | 19:31 |
| alibezz | and made the symbolic link point to it | 19:31 |
| @lisitsyn | bahh why did you do that | 19:31 |
| alibezz | well the data wasnt here hehe i just pointed it | 19:32 |
| @lisitsyn | all you needed was 'git submodule init --update' | 19:32 |
| alibezz | oh nice | 19:32 |
| alibezz | let me see if it works then | 19:32 |
| @lisitsyn | just restore your symlinks | 19:32 |
| @lisitsyn | they were here | 19:32 |
| alibezz | ok no worries | 19:33 |
| @sonney2k | lisitsyn, ok so 17 proposals by now | 19:36 |
| @lisitsyn | sonney2k: + votjakovr + gsomix | 19:36 |
| @sonney2k | lisitsyn, please mark the ones you intend to mentor | 19:36 |
| @lisitsyn | sonney2k: with wish to mentor? | 19:36 |
| @sonney2k | lisitsyn, http://shogun-toolbox.org/page/Events/gsoc2012 | 19:37 |
| @sonney2k | looking at this image | 19:37 |
| @sonney2k | we got 25 applications in the last 3 days | 19:37 |
| @lisitsyn | sonney2k: see # increased just before | 19:37 |
| @lisitsyn | sonney2k: lets calm down - everybody gets less it seems | 19:37 |
| @sonney2k | maybe it is the same - lets see | 19:38 |
| @sonney2k | well we have maybe -10 compared to 2012 | 19:38 |
| @lisitsyn | sonney2k: so we decided about 4? | 19:39 |
| @sonney2k | lisitsyn, and please accept the one you would want to mentor most | 19:39 |
| @sonney2k | lisitsyn, no why? | 19:39 |
| @lisitsyn | sonney2k: well more or less | 19:39 |
| @sonney2k | nothing is set in stone | 19:39 |
| @lisitsyn | okay 5 | 19:39 |
| @sonney2k | yes more or less | 19:39 |
| @lisitsyn | no I don't mean in stone | 19:39 |
| @lisitsyn | HeikoS: where is your supertask guy (tm)? | 19:40 |
| @HeikoS | lisitsyn: having exams :) but wrote me an email, I told him to apply asap | 19:41 |
| alibezz | lisitsyn: until which day can I send the patch? | 19:44 |
| alibezz | lisitsyn: like, I'm gonna send it anyway, of course | 19:45 |
| @lisitsyn | alibezz: good question | 19:45 |
| alibezz | lisitsyn: but to be able to participate of the GSoC selection | 19:45 |
| @lisitsyn | let me check the date | 19:46 |
| @lisitsyn | alibezz: okay it is very unlikely to be that long but assignment due is May 24 | 19:46 |
| alibezz | lisitsyn: okay. fortunately I'll send the sammon mapping until Friday ;) let's see how things work | 19:47 |
| alibezz | hopefully... | 19:47 |
| @sonney2k | alibezz, we decide before may 20 | 19:48 |
| @sonney2k | so anything until then my make us reconsider | 19:48 |
| @lisitsyn | alibezz: ^ so I will have some time to change my mind | 19:49 |
| @lisitsyn | we have to decide ideas ASAP | 19:49 |
| @sonney2k | lisitsyn, ? | 19:49 |
| alibezz | lisitsyn: sure, makes sense | 19:49 |
| @lisitsyn | sonney2k: I mean to ask for slots | 19:49 |
| @lisitsyn | but not real assignment | 19:49 |
| @sonney2k | yes we make our slot request based on the number of excellent proposals we get | 19:50 |
| @sonney2k | so we already *now* put names to tasks to get an idea of #slots | 19:50 |
| alibezz | yeah the things is that week is full of deadlines for me. haha i wish i had known of the applications earlier =( | 19:50 |
| alibezz | but i totally understand it all. if it doesn't work, it's ok! i like helping anyways =) | 19:51 |
| @sonney2k | alibezz, well may 20 is the hard deadline | 19:51 |
| @sonney2k | on may 22 there will be a dedup meeting | 19:51 |
| @sonney2k | err may 24 is the dedup meeting | 19:52 |
| @sonney2k | but in any case google has the last word and does the official announcement on may27 | 19:52 |
| -!- Netsplit *.net <-> *.split quits: syst3mw0rm | 19:53 | |
| @lisitsyn | yeah so one more month of suffering | 19:53 |
| -!- Netsplit over, joins: syst3mw0rm | 19:53 | |
| gsomix | lisitsyn, everyday I'm suffering, life is pain, haha... :( | 19:54 |
| alibezz | lisitsyn: git submodule init --update didn't work actually | 19:54 |
| @sonney2k | submodule update --init | 19:55 |
| @lisitsyn | oops :D | 19:55 |
| @sonney2k | alibezz, other way round! | 19:55 |
| @lisitsyn | my mistake sorry | 19:55 |
| alibezz | huaauahua makes more sense | 19:55 |
| alibezz | it's because both init and update are commands | 19:55 |
| alibezz | who knows... maybe --update was a path. duh | 19:55 |
| -!- ozan [~ozan@ee-167-250.eee.metu.edu.tr] has quit [Quit: Leaving] | 19:56 | |
| alibezz | lisitsyn: i'll need some style tips today, later. sammon mapping has a lot of parameters and i'd like to discuss what's the most elegant way of dealing with them in the shogun architecture. but I'll write/make a bunch of tests here before. and finish this crazy lecture i'm preparing. hahaah | 19:57 |
| @lisitsyn | alright | 19:57 |
| alibezz | lisitsyn: well, the git update worked, but the error remains | 20:01 |
| alibezz | lisitsyn: IOError: [Errno 2] No such file or directory: '../data/fm_train_real.dat' | 20:01 |
| alibezz | any idea? | 20:01 |
| @lisitsyn | alibezz: you said you changed symlinks | 20:02 |
| @lisitsyn | are they listed in 'git status' output? | 20:02 |
| alibezz | actually i'm working in a brand new branch at this very moment | 20:02 |
| alibezz | so no symlinks were changed here | 20:02 |
| @lisitsyn | is there a file ../data/fm_train_real.dat then? | 20:02 |
| alibezz | yup | 20:03 |
| @lisitsyn | what is the dir you run example in | 20:03 |
| @lisitsyn | ? | 20:03 |
| alibezz | if you could execute ~/shogun/examples/undocumented$ python python_modular/converter_isomap_modular.py | 20:03 |
| alibezz | i'd be glad ;) | 20:03 |
| @lisitsyn | run in python_modular folder | 20:04 |
| @lisitsyn | the path is not absolute that's why you get troubles | 20:04 |
| alibezz | yeah it's not absolute but i thought the execution would take the file where the python code is as a reference, not from where i'm running | 20:05 |
| alibezz | but it worked. ;) | 20:05 |

| @lisitsyn | KMcQuisten: hey | 21:20 |
| KMcQuisten | Hope all is going well on your side of the world | 21:21 |
| @lisitsyn | hah yeah | 21:21 |
| @lisitsyn | what about you? | 21:21 |
| KMcQuisten | Not too bad. I put a question up on the mailing list a bit earlier today, and I partially answered my own question, but i'm still having some trouble. | 21:22 |
| @lisitsyn | KMcQuisten: oh sorry hadn't enough time to check your question | 21:23 |
| @lisitsyn | will take a look a bit later | 21:23 |
| KMcQuisten | Righto. | 21:23 |
| KMcQuisten | I didn't know if it was something that i was just missing or if it was a deeper issue | 21:23 |
| KMcQuisten | Sometimes, I must admit, I am an idiot who doesn't see what's in front of his own face *grin* | 21:24 |

| cameron__ | hi, | 22:56 |
| cameron__ | just wondering why when you fetch from github from shogun | 22:56 |
| cameron__ | the data folder is empty | 22:56 |
| @iglesiasg | cameron__: it is in another repo, a submodule | 22:57 |
| @iglesiasg | git submodule update or so should work | 22:57 |
| cameron__ | thanks | 23:02 |
| cameron__ | Trying to update the submodule , but failed the travis build. | 23:50 |
| @iglesiasg | cameron__: mmm I don't understand | 23:53 |
| @iglesiasg | you cannot get the data repository because the travis build failed? | 23:53 |
| cameron__ | i got it | 23:53 |
| cameron__ | made a change | 23:53 |
| cameron__ | tried to do commit and push | 23:53 |
| cameron__ | i did it inside in the submoduel folder, then in the shogun folder | 23:54 |
| cameron__ | changes appeared on github. but didn't seem right | 23:54 |
