| @iglesiasg | hushell, hey there | 00:02 |
|---|---|---|
| -!- travis-ci [~travis-ci@ec2-107-20-114-62.compute-1.amazonaws.com] has joined #shogun | 00:03 | |
| travis-ci | [travis-ci] it's Heiko Strathmann's turn to pay the next round of drinks for the massacre he caused in shogun-toolbox/shogun: http://travis-ci.org/shogun-toolbox/shogun/builds/10907804 | 00:03 |
| -!- travis-ci [~travis-ci@ec2-107-20-114-62.compute-1.amazonaws.com] has left #shogun [] | 00:03 | |
| @iglesiasg | what happened with travis, we have lost it :( | 00:06 |
| hushell | iglesiasg: :) | 00:20 |
| hushell | iglesiasg: have you tried Mosek in the new build system? | 00:21 |
| @iglesiasg | hushell, so to set up Mosek with CMake | 00:21 |
| @iglesiasg | hushell, no, I haven't | 00:21 |
| hushell | I can't find an option to set it up | 00:21 |
| @iglesiasg | hushell, because there is not such an option | 00:22 |
| @iglesiasg | the right way to do it would be adding a FindMosek.cmake file similar to the ones in the cmake/ directory | 00:22 |
| hushell | in CMake, we should have a FIND_PACKAGE(Mosek), right? | 00:23 |
| hushell | yes | 00:23 |
| @iglesiasg | hushell, if you want to just use it for yourself | 00:23 |
| @iglesiasg | you can probably set up something faster that works just locally | 00:24 |
| hushell | or I write a FindMosek.cmake? | 00:24 |
| hushell | okay, so I have to modify the CMakeList.txt? | 00:24 |
| @iglesiasg | hushell, well, if you think you can do that easily, go ahead | 00:24 |
| @iglesiasg | otherwise, I would say you rather focus on the stuff for the SO project :) | 00:25 |
| hushell | I found the Makefile generated by CMake is hard to read | 00:25 |
| @iglesiasg | no idea how hard is to write a .cmake file | 00:25 |
| @iglesiasg | yeah sure, that Makefile is not to be read or edited hehe | 00:25 |
| @iglesiasg | that's why of using CMake | 00:25 |
| hushell | :D | 00:25 |
| @iglesiasg | using a couple of set(CMAKE_INCLUDE_PATH ...) | 00:26 |
| hushell | okay, I'll find a way to add -lmosek | 00:26 |
| @iglesiasg | pointing to your local dirs were your Mosek is placed should be enough to get it working locally | 00:26 |
| @iglesiasg | hushell, however there is another thing that is more important | 00:26 |
| @iglesiasg | so as you are experiencing yourself, our parameter learning methods for SO suck | 00:27 |
| @iglesiasg | BMRM works fine for the stuff that Michal tested but it seems non-trivial to get it working with new stuff | 00:27 |
| @iglesiasg | and my PrimalMosekSOSVM relies on Mosek, which is a pain too | 00:27 |
| hushell | iglesiasg: I see | 00:27 |
| @iglesiasg | one important part of your project is focused on improving this | 00:27 |
| @iglesiasg | with subgradient descent and the Frank-Wolfe | 00:28 |
| @iglesiasg | subgradient descent should be easy, I think | 00:28 |
| hushell | iglesiasg: I thought about implementing the SGD in one day to check my FactorGraphModel code | 00:28 |
| @iglesiasg | hushell, I think it would be a good idea to include a good SGD implementation | 00:28 |
| @iglesiasg | that works with all the models | 00:29 |
| hushell | yeah, anything involves 3rd party code is painful | 00:29 |
| @iglesiasg | so I don't know | 00:29 |
| hushell | iglesiasg: my idea is try your Mosek solver first and then go to SGD | 00:30 |
| @iglesiasg | I'd prefer if you could implement that and get it stable in Shogun rather than fighting to get Mosek to work with it | 00:30 |
| @iglesiasg | but as you wish | 00:30 |
| hushell | since I understand your code more or less | 00:30 |
| @iglesiasg | feel free to comment and modify as you find suitable so it gets more understandable than less :) | 00:31 |
| hushell | iglesiasg: I think your cutting plane implementation is good | 00:31 |
| hushell | yeah, the learning is more complex than inference, so if any part goes wrong, the whole story crashes | 00:32 |
| @iglesiasg | do you think so about learning and inference? | 00:34 |
| hushell | iglesiasg: Thanks for the suggestions, maybe few hours everything be fine :) | 00:34 |
| @iglesiasg | I think that inference is the hard part | 00:34 |
| hushell | iglesiasg: yes, but learning calls inference all the time | 00:34 |
| hushell | this is very risky | 00:34 |
| @iglesiasg | hushell, why is it risky? | 00:35 |
| hushell | iglesiasg: I mean if anything is wrong in inference | 00:35 |
| hushell | just a feeling :) | 00:35 |
| @iglesiasg | hehe ok | 00:36 |
| hushell | okay, I go ahead to fix my problem. | 00:37 |
| hushell | iglesiasg: Good nite! | 00:37 |
| @iglesiasg | hushell, good luck, bye! | 00:37 |

| gsomix | good morning | 08:52 |
| besser82 | mornin' | 09:02 |
| gsomix | wiking, hey. I have a little problem related to cmake. | 09:14 |
| gsomix | wiking, look | 09:14 |
| gsomix | CMake Error: Attempt to add a custom rule to output | 09:14 |
| gsomix | "/Workspace/shogun/build/src/interfaces/python_modular/Multiclass_includes.i.rule" which already has a custom rule. | 09:14 |
| gsomix | after any changes in config with cmake/ccmake | 09:14 |
| thoralf | Heyhey. | 09:20 |
| * gsomix away in uni | 09:24 | |
| thoralf | How bad. | 09:29 |
| * thoralf just burnt 180 CPU-hours just to make evaluation counts overflow. :( | 09:30 | |
| sonne|work | thoralf: how that? | 09:31 |
| thoralf | sonne|work: I used int64_t for counting tp/fp/tn/fn | 09:31 |
| sonne|work | so no way that this overflows... | 09:34 |
| thoralf | You're right. | 09:34 |
| thoralf | But it did. Already looking for some implicit conversion... | 09:35 |
| thoralf | sonne|work: tn = num_classes*num_labels - (tp+fp+tn); <-- only num_classes and num_labels are 32 bit. | 09:36 |
| thoralf | sonne|work: Is it possible that some implicit cast happened? | 09:37 |
| thoralf | tn = int64_t(num_classes)*int64_t(num_labels) - (tp+fp+tn); <-- I dont want to write this. | 09:37 |
| thoralf | sonne|work: The result of (int32_t*int32_t) is int32_t, even if assigned to something bigger. | 09:49 |
| sonne|work | thoralf: sure | 09:50 |
| sonne|work | that is why we should do int64_t(int32_t) before | 09:50 |
| thoralf | sonne|work: I could have seen this, but I was dump. ;) | 09:52 |
| thoralf | sonne|work: Lesson learned. | 09:52 |
| thoralf | Big data is not only about big machines. ;) | 09:53 |
| thoralf | sonne|work: Would you argue against (1l*int32_t*int32_t)? | 09:57 |
| thoralf | Too hacky? ;) | 09:57 |
| thoralf | Hmm. 1l could depend on the platform. | 09:59 |

| sonne|work | iglesiasg: that is weird! tit hsould! | 11:20 |
| sonne|work | it should | 11:20 |
| sonne|work | iglesiasg: I couldn't reproduce the octave crasher either nor could pickle27 | 11:21 |
| sonne|work | so I guess it is some local issue | 11:21 |
| @iglesiasg | oh, ok | 11:21 |
| @iglesiasg | it does not prevent me from working with octave so I can live with it | 11:21 |
| sonne|work | iglesiasg: you should try if a recent swig version would fix it and also that you don't have some clashes w/ other versions of libshogun | 11:22 |
| sonne|work | and that you did compile on *this* machine you run octave on | 11:22 |
| @iglesiasg | sonne|work, I compiled in the machine I am running octave, sure | 11:24 |
| lisitsyn | sonne|work: iglesiasg: what would you use with boolean features? | 11:29 |
| lisitsyn | supervised classification | 11:29 |
| @iglesiasg | mmm let's see | 11:29 |
| lisitsyn | say 128 bits | 11:30 |
| @iglesiasg | why not an SVM? | 11:30 |
| lisitsyn | iglesiasg: I didn't say anything about it so far ;) | 11:30 |
| lisitsyn | linear SVM? | 11:31 |

| iglesiasg_ | I pulled out the cable accidentally, sorry | 11:31 |

| lisitsyn | iglesiasg_: what if semi-supervised? | 11:32 |

| iglesiasg | lisitsyn, semi-supervised like there will be some examples in the training data that are not labelled, right? | 11:32 |
| lisitsyn | iglesiasg: yeah | 11:33 |
| lisitsyn | iglesiasg: well I have keypoints | 11:33 |
| lisitsyn | SIFT/SURF whatever | 11:33 |
| iglesiasg | lisitsyn, Nico mentioned in Berlin that he was working in a solver for that | 11:33 |
| iglesiasg | I am not sure but I think it was SVM too | 11:33 |

| sonne|work | lisitsyn: binary classification -> SVM | 11:44 |
| lisitsyn | sonne|work: haha | 11:50 |
| lisitsyn | sounds like the only method? | 11:50 |
| lisitsyn | well that's what I was going to use indeed | 11:51 |
| iglesiasg | lisitsyn, what do you think about some distance based method like KNN? | 11:51 |
| lisitsyn | iglesiasg: need real-time | 11:51 |
| iglesiasg | using trees it should be possible | 11:51 |
| lisitsyn | so either linear explicit feature map or linear | 11:51 |
| lisitsyn | I'd like to save some time there | 11:51 |

| @iglesiasg | HeikoS, it seems that the messages here are missing a slash ir orgbuilders | 14:20 |
| shogun-buildbot | build #1971 of deb1 - libshogun is complete: Failure [failed compile] Build details are at http://buildbot.shogun-toolbox.orgbuilders/deb1%20-%20libshogun/builds/1971 blamelist: Heiko Strathmann <heiko.strathmann@gmail.com> | 14:20 |
| @iglesiasg | and we should update the README | 14:20 |
| @HeikoS | iglesiasg: any idea about those failing builds ^ | 14:20 |
| @HeikoS | I have no idea what causes this | 14:20 |
| @iglesiasg | HeikoS, me neither, ensemble unit tests | 14:21 |
| @HeikoS | iglesiasg: and whats with the python integration tests failing all of a sudden? | 14:21 |
| @HeikoS | iglesiasg: thats since here | 14:21 |
| @HeikoS | https://travis-ci.org/shogun-toolbox/shogun/builds/10890165 | 14:21 |
| @iglesiasg | yeah I noticed that we lost travis yesterday | 14:22 |
| @HeikoS | string file modular | 14:22 |
| @HeikoS | argh these integration tests cause nothing but annoyance | 14:22 |
| @HeikoS | any idea why it fails? | 14:22 |
| @iglesiasg | no idea at all | 14:23 |
| @iglesiasg | it makes no sense for me | 14:23 |
| @HeikoS | Traceback (most recent call last): File "tester.py", line 182, in <module> got=get_split_string(f[1]) File "tester.py", line 106, in get_split_string strs.extend(e.replace('\\n','\n').splitlines())AttributeError: 'list' object has no attribute 'replace' | 14:23 |
| @HeikoS | no attribute replace? | 14:23 |
| @iglesiasg | including an octave modular example breaks python modular integration test | 14:24 |
| @iglesiasg | it is crazy | 14:24 |
| @HeikoS | probably some python things changed in travis or so | 14:24 |
| @iglesiasg | so is it broken in all the builds from that one_ | 14:24 |
| @iglesiasg | ? | 14:24 |
| @HeikoS | File "tester.py", line 106, in get_split_string | 14:24 |
| @HeikoS | strs.extend(e.replace('\\n','\n').splitlines()) | 14:25 |
| @iglesiasg | you are right, it seems to be about Python | 14:25 |
| @iglesiasg | let me ask in travis IRC channel | 14:26 |
| @HeikoS | https://github.com/shogun-toolbox/shogun/commit/42ca7de15c98c26cf75ad10e5b56109292058d69 | 14:26 |
| @HeikoS | this is the commit responsible | 14:26 |
| @HeikoS | sonne|work: any idea? | 14:27 |
| @iglesiasg | aaah I see | 14:27 |
| @HeikoS | also, rather than using '\n', one should use os.linesep | 14:27 |
| @HeikoS | for platform safety | 14:27 |
| @iglesiasg | HeikoS, mm but I don't think it is just that commit | 14:28 |
| @iglesiasg | that was made 4 months ago | 14:28 |
| @iglesiasg | and travis have been green since that | 14:29 |
| @HeikoS | iglesiasg: I know, but that is the line | 14:29 |
| @iglesiasg | got it | 14:29 |
| @HeikoS | so something probably has changed in travis | 14:29 |
| @HeikoS | and now this idea doesnt work anymore | 14:29 |
| @iglesiasg | that is it | 14:29 |
| @iglesiasg | I think your idea using os.linesep should be the right way | 14:30 |
| votjakovr | HeikoS: do you have any ideas, why we are using MMA (Method of Moving Asymptotes) instead of BFGS? NLopt provides both of them | 14:32 |
| @HeikoS | votjakovr: for ML2? | 14:32 |
| votjakovr | HeikoS: yep | 14:32 |
| @HeikoS | votjakovr: I have no idea why this decision was made ;) | 14:32 |
| @HeikoS | what is used in GPML and GPStuff? | 14:32 |
| votjakovr | HeikoS: BFGS in GPML | 14:33 |
| @HeikoS | votjakovr: do you know about this mma method? | 14:33 |
| votjakovr | HeikoS: not yet :) | 14:33 |
| @HeikoS | do you know how they compare to each other? | 14:33 |
| @HeikoS | votjakovr: http://en.wikipedia.org/wiki/Method_of_moving_asymptotes | 14:34 |
| @HeikoS | haha | 14:34 |
| @HeikoS | http://onlinelibrary.wiley.com/doi/10.1002/nme.1620240207/abstract;jsessionid=A02B054610BF4FAA529A002CFC023A35.d03t04 | 14:34 |
| votjakovr | HeikoS: thanks, i'll check | 14:35 |
| @HeikoS | votjakovr: I have no idea | 14:35 |
| @HeikoS | votjakovr: is there any documentaion about the decision? | 14:35 |
| votjakovr | HeikoS: nope | 14:35 |
| @HeikoS | votjakovr: is it easy to switch between the methods? | 14:35 |
| @HeikoS | votjakovr: maybe we can add an enum that selects the method | 14:35 |
| votjakovr | HeikoS: yeah, just change enum | 14:35 |
| @HeikoS | votjakovr: then we can offer both and set a default value | 14:36 |
| @HeikoS | votjakovr: we can compare both methods on some easy and hard problems and then see | 14:36 |
| votjakovr | HeikoS: yeah sure | 14:36 |
| @HeikoS | votjakovr: ok cool | 14:37 |
| votjakovr | HeikoS: http://ab-initio.mit.edu/wiki/index.php/NLopt_Algorithms | 14:37 |
| votjakovr | HeikoS: we also could use other algorithms | 14:37 |
| votjakovr | HeikoS: check local gradient-based optimization section | 14:38 |
| @HeikoS | votjakovr: I dont know too much about these unconstrained optimization problems | 14:38 |
| @HeikoS | votjakovr: so I would rather stick with the decision made in GPML | 14:38 |
| votjakovr | HeikoS: yeah, me too, i'd like to try to get the same result with GPML and then try some other methods and see the differences | 14:39 |
| @HeikoS | votjakovr: sounds like a good plan? | 14:40 |
| votjakovr | HeikoS: yep, then i'll change default method to BFGS | 14:40 |
| @HeikoS | votjakovr: ok, go ahead! btw are things already starting to work? | 14:42 |
| votjakovr | HeikoS: sorry, not yet, working on it | 14:42 |
| @HeikoS | votjakovr: ok, let me know how things develop :) | 14:43 |
| votjakovr | HeikoS: btw i also changed constructor in gradient model selection, which allows not to pass the tree | 14:45 |
| votjakovr | HeikoS: and use all the parameters | 14:45 |
| @HeikoS | votjakovr: nice! | 14:45 |
| @HeikoS | votjakovr: does this "using all parameters" already work? | 14:45 |
| votjakovr | HeikoS: not yet :) | 14:46 |

| @HeikoS | votjakovr: but thats a very useful feature :) | 14:49 |
| votjakovr | HeikoS: yeah, working on it... btw do you think that, we need to do this: http://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/modelselection/GradientModelSelection.cpp#L187 | 14:50 |
| @HeikoS | what does it do? compare gradients against finite difference approximation? | 14:50 |
| @HeikoS | votjakovr: I think this should be moved to unit tests, they did not exist last year | 14:51 |
| votjakovr | HeikoS: yeah, great, i think so | 14:52 |
| @HeikoS | votjakovr: but we should do it in a gernal way | 14:52 |
| @HeikoS | votjakovr: imagine people implement the gradients in a wrong way | 14:52 |
| @HeikoS | votjakovr: we should check for this | 14:53 |
| @HeikoS | votjakovr: so woul dbe good to have a class that does this for all classes that implement gradients | 14:53 |
| votjakovr | HeikoS: DifferentiableFunction ? | 14:53 |
| @HeikoS | votjakovr: yes | 14:53 |
| @HeikoS | votjakovr: what do you think? | 14:53 |
| votjakovr | HeikoS: yeah i think that is good, to move these functionality there | 14:54 |
| votjakovr | HeikoS: i mean there: http://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/evaluation/DifferentiableFunction.h | 14:59 |

| @iglesiasg | pickle27, all right, cool! | 19:24 |

| pickle27 | ahh indeed | 19:26 |
| pickle27 | okay I will fix and make a PR soon, I asked Andreas to have a look so I'll wait for his feedback | 19:26 |
| @iglesiasg | good | 19:26 |
| @iglesiasg | pickle27, and the data file, is on purpose called foetal? I mean it because of the o | 19:27 |

| pickle27 | iglesiasg: hmm I think there actually was graphics in the ecg notebook | 19:57 |
| pickle27 | iglesiasg: I'll fix that when I resubmit it | 19:57 |

| pickle27 | sonney2k: wiking iglesiasg did you guys see my PR for the ruby modular interface? Just wondering what people think | 20:04 |
| @iglesiasg | pickle27, I didn't check that one at all | 20:04 |
| pickle27 | okay cool, any thoughts on updating to nmatrix from narray> | 20:05 |
| @iglesiasg | I have no idea about that, sorry :S | 20:08 |
| @iglesiasg | what did this guy in the mailing list that seemed to know about Ruby say? | 20:08 |
| pickle27 | iglesiasg: not much, he was advocating a different but no longer maintained numerical lib | 20:09 |
| @iglesiasg | mm I see | 20:09 |
| pickle27 | for me the whole point is that nmatrix is active | 20:09 |
| pickle27 | in general python is much preferred to ruby for science so there isn't a great numerical lib | 20:10 |
| @iglesiasg | aham | 20:10 |
| @iglesiasg | I have no real preference about this | 20:10 |
| pickle27 | but nmatrix and sciruby are active and trying to change that | 20:10 |
| @iglesiasg | and honestly are you saying, I don't think that will be used a lot since Python is preferred | 20:11 |
| @iglesiasg | it can be good then to move to nmatrix and sciruby | 20:11 |
| pickle27 | iglesiasg: main reason I care is because my job next year will be in ruby | 20:11 |
| pickle27 | so just playing around really | 20:11 |
| @iglesiasg | pickle27, will you be doing machine learning in Ruby you think? | 20:11 |
| pickle27 | I do think it will be the right move eventually to go with nmatrix | 20:12 |
| pickle27 | ummm yeah I expect to be doing some machine learning | 20:12 |
| pickle27 | my job is web dev backend | 20:12 |
