| @sonney2k | heh | 00:00 |
|---|---|---|
| @sonney2k | I never think hard | 00:00 |
| shogun-buildbot | build #1125 of deb3 - modular_interfaces is complete: Failure [failed test libshogun] Build details are at http://www.shogun-toolbox.org/buildbot/builders/deb3%20-%20modular_interfaces/builds/1125 blamelist: Sergey Lisitsyn <lisitsyn.s.o@gmail.com> | 00:00 |
| @lisitsyn | I hardly think hard | 00:00 |
| @sonney2k | I am just too soft | 00:00 |
| @lisitsyn | then I fall asleep | 00:00 |
| @lisitsyn | sonney2k: okay one solution | 00:01 |
| @lisitsyn | a) add a base class like DenseFeaturesDataKeeper | 00:02 |
| @lisitsyn | b) inherit a template class from it | 00:02 |
| @lisitsyn | c) add constructors for densefeatures for all supported types | 00:02 |
| @lisitsyn | where we create appropriate data keeper | 00:02 |
| @sonney2k | yeah void* would be a solution | 00:02 |
| van51 | sonney2k: I think the problem is when you call DynArray::insert_element and the array is empty | 00:02 |
| @sonney2k | van51, very well possible | 00:03 |
| @lisitsyn | sonney2k: not really voide | 00:03 |
| @lisitsyn | void* | 00:03 |
| van51 | after it has at least one element it's ok | 00:03 |
| @sonney2k | van51, plesae write a unit test and fix it | 00:03 |
| @lisitsyn | sonney2k: let me try that this weekend and we will see | 00:04 |
| @sonney2k | van51, I think it is also troublesome to call insert_* with an index >= number_of_elements | 00:04 |
| van51 | sonney2k: ok, but can it wait until tomorrow? | 00:04 |
| @lisitsyn | sonney2k: do you expect really significant speedup with that? | 00:04 |
| @sonney2k | lisitsyn, with what? | 00:05 |
| @lisitsyn | sonney2k: with no templates exposed | 00:05 |
| @sonney2k | template removal? | 00:05 |
| @sonney2k | lisitsyn, just try it | 00:05 |
| @sonney2k | remove all %template from .i | 00:05 |
| van51 | sonney2k: I was thinking about that, but I didn't see any index checks on the array classes | 00:06 |
| van51 | so I thought it was up to the user to do it correctly | 00:06 |
| @sonney2k | van51, yeah it was intended like this | 00:06 |
| van51 | sonney2k: I'll try and fix it tomorrow | 00:08 |
| van51 | and will provide some unit tests | 00:08 |
| @lisitsyn | sonney2k: what do we lost this way is compile time typechecking | 00:09 |
| @lisitsyn | which is relevant for C++ | 00:09 |
| @lisitsyn | I mean if I add that thing we get runtime typechecking | 00:12 |
| @lisitsyn | but if you do sth like set_feature_vector(some sgvector of wrong type) | 00:12 |
| @lisitsyn | you get no error in C++ | 00:12 |
| @iglesiasg | good night guys, I am falling asleep on the keyboard :D | 00:13 |
| @lisitsyn | iglesiasg: same here actually | 00:13 |
| @lisitsyn | good night | 00:13 |

| @wiking | sonne|work: ping? shall we have a c4.5 and c5.0 implementation in shogun... as i'm now starting from scratch the random forest implementation so i realised that it's good to have decision trees implemented | 10:58 |
| @wiking | sonne|work: moreover: do anybody is planning to do this in gsoc? so just that i dont take somebody's project... | 10:58 |
| sonne|work | wiking: well there is no OSS implementation of C4.5 and C5.0 code is only slightly better den cat /dev/unrandom | 10:59 |
| sonne|work | wiking: but yes feel free | 10:59 |
| sonne|work | wiking: you could port weka's j45 over to shogun | 11:00 |
| sonne|work | might be the most readable... | 11:00 |
| @wiking | sonne|work: yeah i want first random forest ASAP | 11:00 |
| @wiking | but then i'll do some other tree implementation as well | 11:00 |
| sonne|work | well random forest == some tree impl but just bagged on top | 11:01 |
| @wiking | yeps | 11:01 |
| sonne|work | I think the correct approach would be | 11:01 |
| sonne|work | to do a BaggedClassifier | 11:01 |
| sonne|work | that just trains the same classifier a couple of times | 11:01 |
| sonne|work | using some sampling scheme | 11:02 |
| sonne|work | of the training data points | 11:02 |
| sonne|work | then you can fit in *any* other classifier | 11:02 |
| sonne|work | like svm / tree / knn | 11:02 |
| sonne|work | and you have your random forest as subset | 11:02 |
| @lisitsyn | heyya | 11:02 |
| @wiking | yep | 11:02 |
| @wiking | sounds reasonable | 11:02 |
| @wiking | mmm my battery is running low | 11:03 |

| lambday | lisitsyn: hi | 13:09 |
| @lisitsyn | lambday: hey | 13:09 |
| lambday | I did a rebase... and after that doing make-unittests gives an error.... apparently CMath:init_random has been changed.. | 13:10 |
| lambday | wait let me paste | 13:10 |
| @lisitsyn | yeah that would be better | 13:10 |
| lambday | In function `shogun::CMath::init_random(unsigned int)': | 13:10 |
| lambday | In function `shogun::CMath::init_random(unsigned int)': | 13:10 |
| lambday | shit... wait! | 13:10 |
| lambday | Math.h:458: undefined reference to `shogun::CMath::rand_state | 13:11 |
| lambday | but now its been replaced with something else, I just checked | 13:11 |
| foulwall | sonne|work: sonney2k, could I start a django app for each demo, or make a classification such as supervised, unsupervised etc and start apps for each of it , or just start a 'demo' app and include all the demos in it? | 13:11 |
| @lisitsyn | lambday: did you try to clean up that thing? sounds like something related to recent changes in random | 13:12 |
| lambday | why it would give this error then? I freshly did a make and my src shows new CMath | 13:12 |
| lambday | lisitsyn: I did git pull --rebase upstream develop, and the make clean and make | 13:13 |
| lambday | lisitsyn: yes... seems so | 13:13 |
| @lisitsyn | I think not all things are properly updated in tests | 13:13 |
| lambday | lisitsyn: I think the unit-tests just makes a init_random() call... whose definition in CMath has been changed... should be fine, right? | 13:14 |
| @lisitsyn | lambday: so did clean help | 13:15 |
| @lisitsyn | ? | 13:15 |
| lambday | lisitsyn: nope! :( | 13:15 |
| @lisitsyn | ehmm | 13:15 |
| lambday | clueless :-/ | 13:15 |
| lambday | shall I try cloning somewhere else and then rebase and test again? | 13:16 |
| @wiking | lambday: actually init_random did not change | 13:16 |
| @lisitsyn | lambday: no makes no sense for me | 13:17 |
| @wiking | it's just PRNG behind it is changed | 13:17 |
| @wiking | but the API is the same | 13:17 |
| lambday | wiking: hmm... the error shows undefined reference to CMath::rand_state, I checked and it was there previously, now changed | 13:18 |
| @wiking | yes | 13:18 |
| @wiking | but then you have a problem | 13:18 |
| @wiking | that you dont have the latest CMath.h/cpp | 13:18 |
| lambday | wiking: I do :( I checked and it shows the new init_random() | 13:20 |
| lambday | totally weird :-/ | 13:20 |
| lambday | may be I'm doing something wrong - let me check again | 13:20 |
| sonne|work | foulwall: I single demo app is totally sufficient | 13:22 |
| sonne|work | foulwall: you just need to 'mirror' the urls we have currently in your stuff | 13:22 |
| foulwall | sonne|work: ok... | 13:22 |
| sonne|work | lambday: maybe better do a git clean -dfx (will erase anything not in git) | 13:23 |
| sonne|work | recompile / install / run tests | 13:23 |
| lambday | sonney2k: okay.. thanks... trying | 13:24 |

| sonne|work | hey there | 14:07 |
| hao_ | well I am an applicant of google SoC. | 14:08 |
| hao_ | And I contacted with my mentor, some days ago. He told me to make some contribution on the issues on git | 14:09 |
| hao_ | But only from the name of the issues, I am not sure which one will fit me and I can really make some help. | 14:10 |
| hao_ | And I choosed one, but found there is already some one working on it. | 14:11 |
| hao_ | So I find it may be better choose one issue after asking around. | 14:12 |
| hao_ | Would anyone here please recommend me some issues or works to work with? | 14:12 |
| @iglesiasg | hao_: Is there any of them which interests you? | 14:13 |
| hao_ | Import eliptic curve functions, but lambday is working on it. | 14:15 |

| @lisitsyn | vgorbati: yeah please ask them for some task | 14:31 |
| foulwall | sonne|work: https://github.com/foulwall/shogun_demo, I've finished and created a repo. | 14:32 |
| @lisitsyn | vgorbati: https://github.com/shogun-toolbox/shogun/issues/1102 | 14:32 |
| @lisitsyn | what about it? | 14:32 |
| vgorbati | lisitsyn: I guess I need a bit more info about what needs to be done:) | 14:33 |
| sonne|work | foulwall: ok nice I will move that then to the official shogun toolbox repository. now I only need a patch that removes the demos from shogun-web | 14:33 |
| @lisitsyn | vgorbati: ask sonne|work but in general it should be something like just remove the method and resolve all errors | 14:33 |
| sonne|work | exaclty | 14:34 |
| foulwall | sonne|work: ok I'll send a pr on shogun-web | 14:34 |
| sonne|work | exaaaactly | 14:34 |
| sonne|work | foulwall: thanks | 14:34 |
| vgorbati | sonne|work: so I will need to find all places where this method may be used and replace it by appropriate method calls? | 14:35 |
| sonne|work | foulwall: I think we should start to use some of shogun's data sets for illustration | 14:35 |
| sonne|work | vgorbati: drop die this method | 14:35 |
| sonne|work | no one should use it | 14:35 |
| foulwall | sonne|work: ok | 14:35 |
| sonne|work | vgorbati: shoot, remove! | 14:35 |
| vgorbati | sonne|work: :)ok, understood:) | 14:35 |
| vgorbati | I guess it won't be that hard:) | 14:36 |
| sonne|work | foulwall: you could add support to load the data sets under toy/ from there | 14:37 |
| sonne|work | then just plot the first 2dims of that data set | 14:37 |
| sonne|work | and then any method could use them | 14:37 |
| sonne|work | foulwall: like you have now 'artificial' genatore | 14:37 |
| sonne|work | generator | 14:37 |
| sonne|work | manually clicked | 14:38 |
| sonne|work | now in addition data loaded | 14:38 |
| sonne|work | foulwall: so you need some kind of re-usable component that you can display on any website for this | 14:38 |
| foulwall | sonne|work: you mean data in https://github.com/shogun-toolbox/shogun-data? | 14:38 |
| sonne|work | foulwall: I like your -1, +1 plot the most so all could just use this | 14:38 |
| sonne|work | foulwall: yes | 14:38 |
| foulwall | sonne|work: Ok! I'll do have a look at this repo tonight and do it tomorrow | 14:39 |
| sonne|work | format of that is not yet standardized but will happen this gsoc :) | 14:39 |
| sonne|work | foulwall: thanks a lot | 14:39 |
| sonne|work | foulwall: but you got the idea yes? some say drop down list - to let the user choose to manually do input / select a data file / randomly generate data | 14:40 |
| foulwall | sonne|work: I'll send some little patchs on the existing demo tonight. like when user move the mouse on the curve and show the coordinate | 14:41 |
| foulwall | sonne|work: I see. | 14:41 |
| hao_ | Well. Is that possible to change the gsoc project? Because I guess the project I choosed has been filled. | 14:43 |
| @lisitsyn | hao_: there is no project with no student at all :) | 14:44 |
| hao_ | the result has almost been decided or not? | 14:45 |
| @lisitsyn | hao_: well we definitely have some list of top candidates | 14:47 |
| @lisitsyn | we have to come up with the final decision on 22th I think | 14:48 |
| hao_ | I see. kind of late to begin. | 14:48 |

| @lisitsyn | hao_: https://github.com/shogun-toolbox/shogun/issues?state=open | 14:51 |
| @lisitsyn | is there any issue you'd like to resolve? | 14:51 |
| sonne|work | foulwall: cool! | 14:52 |
| sonne|work | foulwall: regarding the components stuff - what I have in mind is some minimal set of 'widgets' that we can use for almost any example - we simple want DRY'ness to high | 14:53 |
| foulwall | sonne|work: Ok, let me think how to do it tonight. | 14:53 |
| sonne|work | hao_: or any algorithm you want to do or so | 14:54 |
| sonne|work | foulwall: we can always discuss about this - you should not be alone on that | 14:54 |
| foulwall | sonne|work: Ok, always online, never disappear again:) | 14:55 |
| foulwall | sonne|work: demo wiper PR are sent, have a look | 14:58 |
| hao_ | Well I am reading the issues lists, but not sure which one to go. Actually I'd like to implement an algorithm. | 14:58 |

| foulwall | what? | 15:30 |
| gsomix | sonne|work: oh, ok. at this evening, as planned. | 15:30 |
| sonne|work | foulwall: gsomix intends to do data readers for shogun | 15:30 |

| foulwall | gsomix: :) | 15:31 |
| sonne|work | gsomix: real world ray tracing or CG stuff? | 15:31 |
| gsomix | sonne|work: not CG, for optical problems | 15:32 |

| @sonney2k | lisitsyn, lake mueggelsee :D | 21:03 |
| @lisitsyn | sonney2k: ahh the mueggelsee | 21:03 |
| @sonney2k | lisitsyn, the famous one | 21:03 |
| @lisitsyn | sonney2k: never heard about it | 21:03 |
| @sonney2k | lisitsyn, there is a german movie now about it 'shark hunt in lake mueggelsee' | 21:03 |
| @lisitsyn | :D | 21:03 |
| @lisitsyn | haha | 21:03 |
| @lisitsyn | shark | 21:03 |
| @lisitsyn | nice | 21:03 |
| @sonney2k | cool trash | 21:03 |
| @sonney2k | snake mueller the shark hunter | 21:04 |
| @lisitsyn | sonney2k: I mean we could go for breaking the things to stuff like shogun-liblinear etc | 21:20 |
| @lisitsyn | I have no opinion on that | 21:22 |
| @sonney2k | lisitsyn, there are a couple of issues | 21:22 |
| @sonney2k | lots of stuff in shogun is very much connected | 21:22 |
| @sonney2k | van51, good evening! | 21:22 |
| @sonney2k | for example features & preprocessors | 21:22 |
| @sonney2k | kernels <-> features | 21:22 |
| -!- van511 [~van51@athedsl-320452.home.otenet.gr] has joined #shogun | 21:22 | |
| @sonney2k | kernels <-> distances | 21:22 |
| van511 | sonney2k:hey | 21:22 |
| @sonney2k | van511, good evening you too :D | 21:22 |
| van511 | haha | 21:23 |
| van511 | so what were you saying? :) | 21:23 |
| @sonney2k | van511, we are waiting for van5111 | 21:23 |
| @sonney2k | van511, just hi | 21:23 |
| van511 | i'll pass the info to him, don't worry | 21:23 |
| @sonney2k | lisitsyn, so I don't really know how to split this stuff out | 21:23 |
| @lisitsyn | sonney2k: me neither | 21:23 |
| @sonney2k | van511, heh | 21:23 |
| @lisitsyn | just generating ideas as usual :D | 21:24 |
| @sonney2k | so lets say we woudl want to extract kernels into a separate lib | 21:24 |
| @sonney2k | what would we do? | 21:24 |
| @lisitsyn | no no | 21:24 |
| @lisitsyn | makes no sesne | 21:24 |
| @sonney2k | why not? | 21:24 |
| @sonney2k | kernels are a submodule of shogun | 21:25 |
| @lisitsyn | sonney2k: what we can extract are real algorithms | 21:25 |
| @lisitsyn | that's core | 21:25 |
| @lisitsyn | kernel,distances,features | 21:25 |
| @lisitsyn | the mighty trio | 21:25 |
| @sonney2k | we can only extract these algorithms if they are designed to be extracted | 21:25 |
| @sonney2k | consider liblinear / libsvm | 21:25 |
| @sonney2k | we cannot extract them | 21:25 |
| @sonney2k | we have things in there like ctrl+c -> stop or continue | 21:26 |
| @sonney2k | trainign time limit | 21:26 |
| @lisitsyn | yeah true | 21:26 |
| @sonney2k | own kernels | 21:26 |
| @sonney2k | or even dot features | 21:26 |

| -!- van511 is now known as van51 | 21:26 | |
| @sonney2k | lisitsyn, e.g. ocas was designed with that in mind | 21:26 |
| @lisitsyn | yeah same with tapkee | 21:26 |
| @sonney2k | lisitsyn, because vojtech and me were working on it together | 21:26 |
| -!- vgorbati [d4029f22@gateway/web/freenode/ip.212.2.159.34] has quit [Ping timeout: 250 seconds] | 21:27 | |
| @sonney2k | and vojtech wanted ocas to be around also stand-a-lone | 21:27 |
| @sonney2k | lisitsyn, about extracting kernels | 21:28 |
| @sonney2k | one could move the SG* datatypes into a separate lib that everyone then would use | 21:28 |
| @sonney2k | then a kernel could just interface with these | 21:28 |
| @lisitsyn | sonney2k: I seenothing special in SG* types | 21:29 |
| @sonney2k | lisitsyn, we don't want features in kernels | 21:29 |
| @lisitsyn | sonney2k: why? | 21:29 |
| @sonney2k | and kernels currently work with features | 21:29 |
| @sonney2k | lisitsyn, if we split out kernels | 21:29 |
| @lisitsyn | I don't really get that point | 21:29 |
| @lisitsyn | why? | 21:29 |
| @lisitsyn | why to separate them? | 21:30 |
| @sonney2k | kernels should be just kernels not kernels & features | 21:30 |
| @lisitsyn | sounds pretty painful | 21:32 |
| @sonney2k | it is all painful | 21:33 |
| @sonney2k | think about some library like say libsvm using other shogun classifiers as dynamically generated input | 21:34 |
| @sonney2k | then we cannot extract | 21:34 |
| @sonney2k | this whole module separation thing only works when you limit functionality | 21:34 |
| @lisitsyn | sonney2k: yes we can't extract that | 21:34 |
| @lisitsyn | yes sure | 21:34 |
| @sonney2k | maybe not bad but one has to keep that in mind | 21:35 |
| @lisitsyn | sonney2k: what is most important thing I see | 21:35 |
| @sonney2k | if we would really do it I would say each directoy in shogun should be a module | 21:35 |
| @lisitsyn | vojtech maintains ocas | 21:36 |
| @lisitsyn | I maintain tapkee | 21:36 |
| @sonney2k | yeah but if there is 0 interaction between the two it doesn't help us | 21:36 |
| @sonney2k | e.g. libsvm/liblinear | 21:36 |
| @lisitsyn | yes sure | 21:36 |
| @sonney2k | we take their code | 21:36 |
| @sonney2k | modify it | 21:36 |
| @sonney2k | heavily | 21:36 |
| @lisitsyn | we have to modify their code yes | 21:36 |
| @sonney2k | but that's it | 21:37 |
| @sonney2k | we don't update and are not pushed to update | 21:37 |
| @sonney2k | and they don't care about our extensions | 21:37 |
| @sonney2k | it works fine with tapkee because you keep it up-to-date also wrt shogun interface | 21:37 |
| @lisitsyn | yes I understand | 21:38 |
| @sonney2k | but in the end it gives shogun not more - you work for tapkee and not directly on shogun | 21:38 |
| @sonney2k | if you were a non-core shogun author | 21:38 |
| @sonney2k | shogun would benefit | 21:38 |
| @sonney2k | but yes that would be the way to go | 21:38 |
| @lisitsyn | sonney2k: there are a lot of drawbacks in that for sure | 21:39 |
| @sonney2k | someone like you taking care of his own lib but who also wants to get exposure with shogun | 21:39 |
| @sonney2k | in addition ML people are like grass hoppers | 21:40 |
| @sonney2k | they move from topic to topic in no time | 21:40 |
| @lisitsyn | yeah | 21:40 |
| @sonney2k | and rarely want to maintain any code | 21:40 |
| @sonney2k | I recall the ML-OSS discussions we had in the workshops | 21:41 |
| @sonney2k | people said I give out my code sure but I don't want to support it | 21:41 |
| @sonney2k | and it is also different somehow - once an algorithm works it is finished | 21:42 |
| @sonney2k | final nothing more needed | 21:42 |
| @sonney2k | there are only new algorithms improving that algorithm | 21:42 |
| @lisitsyn | you make me feel depressed :D | 21:42 |
| @lisitsyn | usually i think there is no sense in all that stuff | 21:43 |
| @sonney2k | votjakovr, please cheer lisitsyn up hand him a vodka or something | 21:43 |
| @sonney2k | van51, wiking you too | 21:43 |

| @sonney2k | lisitsyn, I recall your last years phase when we did the SG* transition and stuff was like boom kaboom for weeks | 21:44 |
| @lisitsyn | sonney2k: what do you mean? | 21:44 |
| @sonney2k | it had the same effect on you :D | 21:44 |
| @sonney2k | no I think we have lots of cool algorithms already now but we really just need to expose them better | 21:45 |
| @sonney2k | and sure there always is algoirthm X doing somethign better for whatever use case | 21:45 |
| @sonney2k | or framework Y for some other usecase | 21:45 |
| @sonney2k | we just have to find (and be satisfied with) our niche | 21:46 |
| @lisitsyn | motivation is very hard to find | 21:46 |
| @sonney2k | and to me it is currently the hardware I have access to: single machine but multicore | 21:47 |
| @lisitsyn | I feel bad with doing something that is not going to be used | 21:47 |
| @sonney2k | you always want to change the world in a day | 21:47 |
| @sonney2k | shogun is being used | 21:47 |
| @lisitsyn | hah | 21:47 |
| @lisitsyn | yes of course | 21:47 |
| @lisitsyn | I am not satisfied with regular day-to-day things | 21:48 |
| @lisitsyn | we need a breakthrough | 21:48 |
| @sonney2k | the mailinglist even has >300 subscribers | 21:48 |
| @lisitsyn | sonney2k: that's soviet-style I want a breakthrough :D | 21:51 |
| @lisitsyn | sonney2k: but actually it is the way software evolves | 21:52 |

| @lisitsyn | votjakovr: I am half of siberian, my mother is from kemerovo | 22:09 |
| @sonney2k | heh | 22:09 |
| @sonney2k | I would need to practice | 22:09 |
| @sonney2k | lisitsyn, look https://github.com/shogun-toolbox | 22:09 |
| @sonney2k | we have a new repository | 22:09 |
| @lisitsyn | shogun-demo? | 22:10 |
| @lisitsyn | alrighht | 22:10 |
| @sonney2k | lisitsyn, yes has some nice gp demo now in there | 22:11 |

| votjakovr | lisitsyn: Awesome :) I was there once, there's a lot of mines | 22:12 |
| @sonney2k | it totally is kernel build time today :) | 22:15 |
| @sonney2k | my uptime is just to high | 22:15 |
| @sonney2k | that is something that needs to be dealt with | 22:15 |

| votjakovr | Btw I'd like to ask: Is there a good way to get log of each element of eigen3 vector? I mean something like vector.cwiseSqrt(). | 22:21 |

| @sonney2k | it is good to have a eigen3 expert around | 22:31 |

| @sonney2k | dvalcarce, we have moved everything to shogun-demo now | 22:31 |
| @sonney2k | van51, bringing good news? | 22:31 |
| dvalcarce | sonney2k, I have just realize | 22:31 |
| dvalcarce | sonney2k, should I move the PR to the new repo? | 22:32 |
| @sonney2k | dvalcarce, yes totally! | 22:32 |
| @sonney2k | the new contour stuff looks soooooo much better | 22:32 |
| dvalcarce | sonney2k, ok! btw, what do you mean by using more values at the colorbar? | 22:32 |
| dvalcarce | thx :) | 22:33 |
| dvalcarce | sonney2k, I think I have a basic upload system at bakufu, too | 22:33 |
| van51 | my router is really struggling with the wifi these days :S | 22:34 |
| van51 | it's in the next room and I keep getting dc'd | 22:34 |
| van51 | anyway | 22:34 |
| van51 | sonney2k: I haven't started them yet | 22:34 |
| van51 | I started looking at the issue with some debug messages to see what it was about but I didn't get anywhere | 22:35 |
| van51 | so I am going to begin them now | 22:35 |
| @sonney2k | van51, yeah I had these issues with linux kernel >=3.3 | 22:35 |
| @sonney2k | so I am now stuck in 3.2.45 or whatever it is now | 22:35 |

| van511 | were any of my messages delivered? :) | 22:37 |
| @sonney2k | yes 6 | 22:37 |
| @sonney2k | van511, please do a test - we have them in tests/unit/* | 22:38 |
| van511 | ok, I'm on it :) | 22:38 |
| @sonney2k | dvalcarce, cool! | 22:38 |

| @sonney2k | dvalcarce, once you have a bit more I should create shogun-bakufu also in shogun-toolbox/ and move it over | 22:42 |
| @sonney2k | lisitsyn, do you know whether one can give access rights to only one of the repositories on github? | 22:43 |
| @sonney2k | not all at once? | 22:43 |
| @lisitsyn | sonney2k: I think so | 22:43 |
| @sonney2k | it would make sense for both foulwall and dvalcarce | 22:43 |

| @sonney2k | alright | 22:48 |
| @sonney2k | I have to reboot to the new kernel | 22:49 |
| @sonney2k | brb (hopefully) | 22:49 |
| @sonney2k | Re! | 22:56 |
| @sonney2k | lisitsyn, did you see cat's mail? | 22:56 |
| @lisitsyn | sonney2k: yes | 22:56 |
| @sonney2k | so it is pretty obvious | 22:56 |
| @sonney2k | no chance for us to get even more slots | 22:57 |
| @lisitsyn | yeah looks like | 22:57 |
| @sonney2k | man I am hungry again | 22:58 |
| @sonney2k | is it normal to have dinner twice? | 22:58 |
| @lisitsyn | sonney2k: depends | 22:58 |
| @lisitsyn | :D | 22:58 |
| @sonney2k | yeah I manage to gain some weight :D | 23:00 |
| @sonney2k | you know whales & water -> no problems | 23:00 |
| @lisitsyn | sonney2k: if you are not having beer belly yet it must be ok to have a dinner twice :) | 23:01 |
| -!- votjakovr [~votjakovr@host-46-241-3-209.bbcustomer.zsttk.net] has quit [Quit: Leaving] | 23:01 | |
| @lisitsyn | I mean you are the first world war veteran you must have a good metabolistic stuff | 23:02 |
| @lisitsyn | to be in shape still | 23:02 |
| dvalcarce | sonney2k, I like to focus on bakufu, what should I do next? | 23:07 |
| dvalcarce | (I don't have much time, my finals begin next week, but I'll try to do something) | 23:07 |
| @sonney2k | dvalcarce, anything you can do for bakufu like file upload some minimal user management | 23:09 |
| @sonney2k | as in each user should have his own space / directory to store stuff in - the standard django-registration struff | 23:09 |
| @sonney2k | dvalcarce, I know you don't have much time but in case you still have more you could train e.g. visualize 2 dims of the data or train some simple linear model on it (if we focus on classification for now) etc etc | 23:11 |
| @sonney2k | but certainly your finals are more important | 23:12 |
| @sonney2k | ..than whole gsoc probably | 23:12 |
| dvalcarce | sonney2k, yeah, finals are important... but gsoc is cooler :P | 23:13 |
| dvalcarce | i will check user management | 23:13 |
| -!- hushell [~hushell@8-92.ptpg.oregonstate.edu] has quit [Quit: leaving] | 23:14 | |
| @sonney2k | dvalcarce, once you have sth I should create shogun-bakufu and we shoudl start merge things over | 23:15 |
| dvalcarce | sonney2k, right now (https://github.com/dvalcarce/shogun-bakufu) you can upload and delete documents | 23:16 |
| van51 | sonney2k: so, the insert_element(obj, 0) when the array is empty is idd causing a seg fault | 23:16 |
| van51 | but what I can't understand is how did the octave example run smoothly then | 23:16 |
| van51 | because I used the same logic in CombinedKernel as well | 23:17 |
| @sonney2k | van51, no idea - write a unit test and fix this insert_element to work in all reasonable cases | 23:20 |
| van51 | okie | 23:21 |
| @sonney2k | dvalcarce, I will move it over then | 23:29 |
| van51 | sonney2k: actually, valgind reports it as an invalid memory read | 23:29 |
| van51 | but there is no seg fault | 23:29 |
| @sonney2k | van51, lucky then | 23:29 |
| @sonney2k | dvalcarce, but not now (too tired) | 23:29 |
| van51 | so maybe octave is more tolerant in those situations than python? | 23:29 |
| @sonney2k | van51, no we were just lucky | 23:30 |
| van51 | how? | 23:30 |
| @sonney2k | we should always check if valgrind | 23:30 |
| @sonney2k | well some corruption in not too important memory | 23:30 |
| @sonney2k | but no idea really | 23:30 |
| @sonney2k | just relax and fix it | 23:31 |
| van51 | hehe | 23:31 |
| van51 | i just find it weird! | 23:31 |
| dvalcarce | sonney2k, ok, there is no hurry :) | 23:31 |
| @sonney2k | I gave up trying to understand all bugs | 23:31 |
| @sonney2k | alright that's it for me for today cya! | 23:39 |
| van51 | cya! | 23:40 |
| dvalcarce | bye! | 23:43 |
