| @iglesiasg | wiking, sonney2k, hey guys, a question about the notebooks and the webpage | 00:39 |
| @iglesiasg | so if I update one of the notebooks shown in http://shogun-toolbox.org/page/documentation/notebook | 00:39 |
| @iglesiasg | as I have done with the abstract of one of the ICA notebooks | 00:39 |
| -!- pickle271 [~kevin@24-212-221-132.cable.teksavvy.com] has joined #shogun | 00:39 | |
| @iglesiasg | what needs to be done so that it gets updated in the website? | 00:40 |
| @iglesiasg | pickle271, hey there! How are you doing? | 00:40 |
| pickle271 | good man! | 00:40 |
| pickle271 | just finished moving to Ottawa Canada | 00:40 |
| pickle271 | got internet setup in my new apt this morning | 00:40 |
| pickle271 | starting work tomorrow! | 00:40 |
| @iglesiasg | pickle271, started the new job already? | 00:40 |
| @iglesiasg | nice then! | 00:40 |
| @iglesiasg | pickle271, btw, I did a tiny mod in one of your notebooks | 00:41 |
| @iglesiasg | pickle271, see here http://shogun-toolbox.org/page/documentation/notebook | 00:41 |
| @iglesiasg | the BSS audio one had a little bit long abstract to be shown in the website | 00:41 |
| @iglesiasg | so I have basically divided that markdown cell into two cells | 00:41 |
| @iglesiasg | pickle271, hope there is no problem for you with that! | 00:41 |
| pickle271 | ahh cool | 00:41 |
| pickle271 | looks good! | 00:42 |
| @iglesiasg | all right | 00:42 |
| @iglesiasg | no idea when it will get updated in the website though | 00:42 |
| @iglesiasg | with any luck it will happen after the nightly build | 00:42 |
| pickle271 | yeah the release looks good! | 00:42 |
| pickle271 | I hope to have time to do some shogun stuff in a 2 weeks or so | 00:43 |
| pickle271 | I have a fun example project in mind! | 00:43 |
| @iglesiasg | cool | 00:43 |
| @iglesiasg | what is it about? | 00:43 |
| pickle271 | still a wip | 00:43 |
| pickle271 | basically making a basic AI for mario kart using some vision and ml | 00:44 |
| @iglesiasg | oh, it sounds challenging! | 00:44 |
| @iglesiasg | so nice :) | 00:44 |
| pickle271 | yeah i dunno if it will go anywhere I've just been playing around | 00:45 |
| pickle271 | I have the framework setup | 00:45 |
| pickle271 | now I need to do the actual machine learning part | 00:45 |
| @iglesiasg | how is the ml part? | 00:46 |
| @iglesiasg | I mean, what data to use and what is the objective of the ml module | 00:46 |
| pickle271 | not totally sure yet, I was actually going to see what people thought was best | 00:46 |
| pickle271 | I basically have a data set that is the frames of the game and what a user (aka me) was doing on the gamepad at that time | 00:47 |
| pickle271 | and thats all I have done | 00:47 |
| shogun-buildbot | build #273 of osx1 - libshogun is complete: Failure [failed compile] Build details are at http://buildbot.shogun-toolbox.org/builders/osx1%20-%20libshogun/builds/273 blamelist: Fernando Iglesias <fernando.iglesiasg@gmail.com> | 00:47 |
| @iglesiasg | I see | 00:47 |
| shogun-buildbot | build #274 of osx1 - libshogun is complete: Failure [failed compile] Build details are at http://buildbot.shogun-toolbox.org/builders/osx1%20-%20libshogun/builds/274 blamelist: Fernando Iglesias <fernando.iglesiasg@gmail.com> | 00:48 |
| lisitsyn | oh guys never go to computer vision | 00:48 |
| lisitsyn | :D | 00:48 |
| pickle271 | I saw a really old video / paper on NNs that did something similar with a real car | 00:48 |
| lisitsyn | stupid amount of time tuning parameters and stuff argh | 00:48 |
| pickle271 | it only drove like 15 Km per hour though | 00:48 |
| pickle271 | lisitsyn: haha I know, I kept trying to drift my MASc over to ML | 00:49 |
| lisitsyn | pickle271: I am still working on that shit remember? | 00:49 |
| pickle271 | lisitsyn: yeah I do, man that sucks | 00:49 |
| lisitsyn | everything is overdued arght | 00:49 |
| lisitsyn | however I resolved most of the issues | 00:49 |
| pickle271 | lisitsyn: also in CV there is this nagging notion of - should I make this whole alg better or should I add a special case to deal with this particular problem | 00:50 |
| @iglesiasg | pickle271, yeah, it also reminds me about sth Ng did with an helicopter that could fly upside down | 00:50 |
| lisitsyn | pickle271: apparently that shitloader is moving with up to 20 degree angle | 00:50 |
| pickle271 | iglesiasg: yeah, its deffs been done before | 00:50 |
| lisitsyn | so I had to ouhhuh | 00:50 |
| pickle271 | iglesiasg: but no one has opened up their framework | 00:50 |
| lisitsyn | pickle271: for now I am using sobel response to maintain background model :D | 00:51 |
| lisitsyn | apparently it is better | 00:51 |
| pickle271 | iglesiasg: so exposing the problem in terms of input and output is my main goal, not performance | 00:51 |
| @iglesiasg | pickle271, I see. In any case, it would be something interesting to work on, and really cool results very likely! | 00:51 |
| pickle271 | lisitsyn: cool, I'm not familiar with that technique in that context | 00:51 |
| lisitsyn | pickle271: well just MOG2 from opencv on top of sobel | 00:52 |
| lisitsyn | pickle271: somehow it works :D | 00:52 |
| pickle271 | lisitsyn: that makes some sense actually | 00:52 |
| lisitsyn | pickle271: the problem is that it outputs a bunch of points | 00:52 |
| lisitsyn | I mean no strong areas | 00:52 |
| lisitsyn | so camshift will come mad | 00:52 |
| lisitsyn | I just fit a rectangle | 00:52 |
| lisitsyn | I am afraid it is not robust enough but trainset works.. | 00:53 |

| pickle271 | lisitsyn: thats all you can do | 00:54 |
| pickle271 | lisitsyn: the trainset I mean | 00:54 |
| lisitsyn | pickle271: yeah but trying to keep in mind other cases | 00:54 |
| lisitsyn | when e.g. a man walks here | 00:54 |
| lisitsyn | no idea how would it work | 00:54 |
| pickle271 | lisitsyn: I was working on an industry project and they never gave us data, so we had to keep trying to make our own that fit their use case | 00:54 |
| pickle271 | project crashed and burned | 00:54 |
| lisitsyn | haha | 00:55 |
| lisitsyn | pickle271: no these guys gave me a lot of data | 00:55 |
| lisitsyn | 2.8 gb of videos | 00:55 |
| lisitsyn | pickle271: I feel pretty guilty because they consult me when I ask and etc | 00:55 |
| lisitsyn | but I still overdue that shit :D | 00:55 |
| @iglesiasg | all right guys, time to sleep for me | 00:55 |
| @iglesiasg | see you tomorrow! | 00:55 |
| lisitsyn | iglesiasg: good night! | 00:55 |
| pickle271 | iglesiasg: night | 00:56 |
| @iglesiasg | pickle271, good luck with the new job! | 00:56 |

| lisitsyn | :) | 09:29 |
| @iglesiasg | oui then :D | 09:29 |
| lisitsyn | iglesiasg: NEIN :D | 09:35 |
| lisitsyn | iglesiasg: have you seen 'predator' tracker? | 09:36 |
| @iglesiasg | lisitsyn, nope | 09:36 |
| lisitsyn | iglesiasg: http://www.youtube.com/watch?v=1GhNXHCQGsM | 09:36 |
| lisitsyn | iglesiasg: it learns the appearance of object to support further tracking | 09:37 |
| @iglesiasg | lisitsyn, cool stuff | 09:39 |
| lisitsyn | iglesiasg: don't know whether it is state of the art still though | 09:39 |
| lisitsyn | iglesiasg: but the idea is here now | 09:39 |
| @iglesiasg | I think the fact that it can change from tracking one thing to another so quickly is advanced stuff | 09:40 |
| @iglesiasg | like he gave the bounding box and started tracking another thing | 09:40 |
| lisitsyn | iglesiasg: yeah it is pretty much advanced | 09:40 |
| lisitsyn | iglesiasg: but I like the idea actually | 09:41 |
| lisitsyn | when you maintain a model | 09:41 |
| @iglesiasg | it is open source | 09:45 |
| lisitsyn | iglesiasg: yeah with crazy amount of matlab code :) | 09:51 |

| besser82 | lisitsyn: shouldn't it be easy to run MatLab-code with Octave?!? | 10:28 |
| lisitsyn | besser82: yes why not | 10:28 |
| lisitsyn | besser82: I meant matlab = unreadable :D | 10:28 |
| besser82 | lisitsyn: Ahh ;) | 10:28 |
| lisitsyn | and like matlab software ~ bad designed software | 10:28 |
| besser82 | lisitsyn: I have a personal matlab to python compiler :-P | 10:29 |
| besser82 | lisitsyn: btw. Marburg University starts dropping Matlab ;) | 10:30 |
| besser82 | lisitsyn: replacement: Pyton + Scipy | 10:30 |
| lisitsyn | besser82: that's the human way to do science | 10:30 |
| besser82 | lisitsyn: :D | 10:31 |
| besser82 | lisitsyn: They actually dropped it because of increasing license-fees :-P | 10:31 |
| lisitsyn | besser82: that's ok too, no matter how they come from the dark side :D | 10:32 |
| besser82 | lisitsyn: XD | 10:33 |
| besser82 | lisitsyn: Or or like Uncle Wong says: Da FOSSSSSSSS iz da so mut beeeeedaahhh ;) | 10:34 |
| lisitsyn | besser82: foss be good | 10:35 |
| lisitsyn | :D | 10:35 |
| besser82 | lisitsyn: btw. I just engaged an "Applied Physics BSc." for optimizing the SVM^bright algos ;) | 10:36 |
| lisitsyn | besser82: how? | 10:37 |
| besser82 | lisitsyn: He's a friend of mine from the Fedora community and I asked him to do the sucking work :-P | 10:37 |
| lisitsyn | ahh | 10:37 |
| lisitsyn | besser82: do you want to release it standalone too? | 10:38 |
| besser82 | lisitsyn: Like "Hey Budyy! Ya know about SVM^sh*t? I wanna make a FOSS alternative which is much better, but need someone to look if there's room for optimazation in algos" | 10:38 |
| besser82 | lisitsyn: Yes | 10:39 |
| lisitsyn | besser82: as shared lib? | 10:39 |
| besser82 | lisitsyn: I actually planned it to be a C++ shlib && cli-tools | 10:39 |
| besser82 | lisitsyn: with the possibility to dlopen custom-kernels through a factory ;) | 10:39 |
| lisitsyn | besser82: I see | 10:40 |
| besser82 | lisitsyn: and possibly some Cython-style Python-module | 10:40 |
| lisitsyn | besser82: I actually would like to see shogun using some libs | 10:41 |
| lisitsyn | instead of being thaat gigantic | 10:41 |
| besser82 | lisitsyn: me too ;) | 10:41 |
| lisitsyn | may be liblinear should be 'fixed' that way too | 10:41 |
| besser82 | lisitsyn: What's the beef with liblinear? | 10:41 |
| besser82 | lisitsyn: I'm maintaining that for FC | 10:42 |
| besser82 | lisitsyn: and have good connection to upstream ;) | 10:42 |
| lisitsyn | besser82: well usual liblinear doesn't support that 'coffin' thing | 10:42 |
| lisitsyn | i.e. callback dot and add operations | 10:42 |
| lisitsyn | they act like it is dense | 10:42 |
| besser82 | lisitsyn: I see; so it was customized by S?ren, rye? | 10:43 |
| lisitsyn | yeah | 10:43 |
| lisitsyn | besser82: multiclass was customized by me | 10:43 |
| lisitsyn | iirc | 10:43 |
| besser82 | lisitsyn: Lemme see, if can get a patch set upstream ;) | 10:43 |
| lisitsyn | besser82: do you know its developers? | 10:43 |
| besser82 | lisitsyn: Yeah, not in person. but yes | 10:44 |
| lisitsyn | besser82: we can prepare a patch and propose | 10:44 |
| lisitsyn | I have no idea whether sonne|work proposed it before | 10:44 |
| lisitsyn | probably they know about that way | 10:44 |
| besser82 | lisitsyn: And it shouldn't be much diffcult for me to get it in, with me wearing my "RedHat" :-P | 10:44 |
| lisitsyn | besser82: if it was shared library I wouldn't mind if we used linking | 10:45 |
| lisitsyn | no idea what others think | 10:45 |
| lisitsyn | but I believe it is better | 10:45 |
| besser82 | lisitsyn: liblinear Makefile builds a shlib by default ;) | 10:45 |
| lisitsyn | besser82: well yeah I mean 'proper' shlib ;) | 10:46 |
| sonne|work | besser82: it is not easy to do that with liblinear but possible - in the end you need to boil down all liblinear operations into dot, dense_dot, add_to_dense_vec such stuff | 10:46 |
| lisitsyn | which can be used easier | 10:46 |
| sonne|work | rather similar to what ocas does | 10:46 |
| besser82 | lisitsyn: I see. So heavy API / ABI changes? | 10:46 |
| lisitsyn | sonne|work: do you think it is better to have multiple shlibs around? | 10:46 |
| lisitsyn | besser82: well yeah some changes | 10:46 |
| sonne|work | in addition one would need to register print and error functions, malloc/free/calloc functions etc | 10:47 |
| lisitsyn | ah yeah | 10:47 |
| sonne|work | not easy but surely possible | 10:47 |
| besser82 | sonne|work, lisitsyn: Who will dooooo it? | 10:47 |
| lisitsyn | besser82: actually that's their drawback | 10:47 |
| lisitsyn | I mean when you develop a library | 10:47 |
| lisitsyn | you should think of providing that callbacks :D | 10:48 |
| lisitsyn | besser82: I am still unavailable but I want to do that some day | 10:48 |
| sonne|work | besser82: what is their incentive to provide a framework like this or even to accept patches like this? | 10:48 |
| sonne|work | I don't see it happening | 10:48 |
| lisitsyn | yeah I am afraid of that too | 10:48 |
| lisitsyn | I see it is much easier to just maintain a fork of liblinear | 10:49 |
| besser82 | sonne|work, lisitsyn: I can possibly get that stuff into SVM^bright as well ;) | 10:49 |
| lisitsyn | with such changes | 10:49 |
| besser82 | sonne|work, lisitsyn: If that would make sense? | 10:49 |
| lisitsyn | besser82: no idea! | 10:49 |
| sonne|work | besser82: it is work no idea who will do it | 10:49 |
| lisitsyn | besser82: as for svm bright - please keep everything callbacked' :) | 10:50 |
| besser82 | lisitsyn: Sure ;) | 10:50 |
| lisitsyn | malloc/print/data access | 10:50 |
| lisitsyn | errors too may be | 10:50 |
| besser82 | lisitsyn: I actually planned to setup a nice class-based API/ABI ;) | 10:51 |
| sonne|work | there is some update_linear component stuff in svm light which we have heavily changed | 10:51 |
| sonne|work | all far from easy to migrate even w/ a clean API | 10:51 |
| besser82 | lisitsyn: So full controll for your code ;) | 10:51 |
| besser82 | lisitsyn: and some nice exception handling in case of problems ;) | 10:53 |
| lisitsyn | besser82: yeah | 10:53 |
| besser82 | lisitsyn: Everything in fully transparent ;) | 10:55 |
| besser82 | lisitsyn: providing easy-all-in-one-calls && advanced its-all-up-to-you-headers ;) | 10:56 |
| lisitsyn | besser82: haha too much marketing already ;) | 10:57 |

| besser82 | wiking: c-a has been fixed in meaning of storage :) | 20:34 |
| @wiking | ok so now it's already there? | 20:35 |
| besser82 | wiking: /dev/vdb is up and just needs formatting && fstab :D | 20:35 |
| @wiking | besser82: shall i do it? | 20:35 |
| besser82 | wiking: if you want :) | 20:35 |
| @wiking | ok | 20:36 |
| @wiking | let's see | 20:36 |
| @wiking | fdisk :) | 20:36 |
| besser82 | wiking: or sfdisk or parted :-P | 20:36 |
| @wiking | hehehe done with fdisk :P | 20:36 |
| @wiking | /dev/vdb1 63 52428799 26214368+ 83 Linux | 20:36 |
| @wiking | should be good | 20:37 |
| besser82 | sonney2k, sonne|osx, sonne|work: Yo! :D Do you have a minute? | 20:37 |
| besser82 | wiking: +1 :D | 20:37 |
| @wiking | besser82: where should i mount it? | 20:37 |
| besser82 | wiking: I'd use /srv | 20:37 |
| besser82 | wiking: because of selinux ;) | 20:37 |
| @wiking | besser82: in /etc/fstab is it ok if i refer to it by /dev/vdb1 | 20:38 |
| @wiking | or should it be UUID? | 20:38 |
| besser82 | wiking: Like you want ;) | 20:38 |
| besser82 | wiking: shouldn't change | 20:38 |
| besser82 | wiking: but with autocheck enabled ;) like ... 1 1$ | 20:38 |
| @wiking | /dev/vdb1 25G 44M 24G 1% /srv | 20:39 |
| besser82 | wiking: and don't forget to `touch /.autorelabel && reboot` | 20:39 |
| besser82 | wiking: to make selinux happy | 20:39 |
| @wiking | eh? | 20:40 |
| besser82 | wiking: this will make selinux restore all default context on new mounted fs ;) | 20:41 |
| besser82 | wiking: and reboot | 20:41 |
| besser82 | wiking: or shall I do just quick? | 20:42 |
| @wiking | besser82: yeps | 20:43 |
| besser82 | wiking: allrighty :D You will be logged out in a second ;) | 20:44 |
| -!- sonne|osx [~sonne@f053047066.adsl.alicedsl.de] has quit [Quit: sonne|osx] | 20:44 | |
| @wiking | i think i've logged out before | 20:49 |
| @wiking | besser82: let me know when it's back | 20:49 |
| @wiking | ah ok it's back | 20:51 |
| @wiking | cool | 20:51 |
| besser82 | wiking: Everything is fine? | 20:52 |
| @wiking | seems like | 20:53 |
| besser82 | wiking: for me too ;) | 20:53 |
| @wiking | ok now we have to figure out how to share container instances between nodes :P | 20:58 |
| @wiking | but since docker uses aufs | 20:58 |
| @wiking | we can just use the diff of the container image | 20:58 |
| @wiking | i.e. the changes since it got fired up | 20:59 |
| @wiking | and that cannot be toooo much | 20:59 |
| @wiking | i.e. couple of megabytes | 20:59 |
| besser82 | wiking: I'm afraid AUFS and selinux don't play nice with oneanother :( | 20:59 |
| @wiking | mmm well i guess we'll have to try :P | 21:00 |

| taylan | Hi everyone..I got a couple of small questions about training a classifier with shogun.. | 21:21 |
| taylan | - 1. Do I need to scale the features I provide? | 21:22 |
| @wiking | taylan: 1) depends on the classifier you are trying to use. but as a general rule of thumb it's worth to try scaling | 21:23 |
| taylan | 2. Is there a module which optimizes kernel parameters, or should I write a wrapper around the crossvalidation evaluator to optimize the choice of kernel parameters? | 21:23 |
| @wiking | 2) modelselection should do this for you | 21:23 |
| taylan | Thanks wiking! | 21:23 |
| @wiking | nw | 21:23 |
| taylan | I will check the model selection.. | 21:23 |
