| wiking | sonne|osx: serialize all the possible objects into a file | 08:26 |
| wiking | reads it | 08:26 |
| sonne|osx | wiking: we really need a gdb trace | 08:26 |

| wiking | sonne|osx: couldn't find such option for ctest yet | 08:27 |
| sonne|osx | I have no clue how to debug this | 08:27 |
| sonne|osx | wiking: no we can do it when running our test | 08:27 |
| sonne|osx | wiking: like this | 08:27 |
| wiking | sonne|osx: how... do u know the ctest command for it? | 08:27 |
| sonne|osx | test | 08:27 |
| wiking | btw: do you know how to create a tmpfs? | 08:27 |
| sonne|osx | test || gdb test | 08:27 |
| sonne|osx | wiking: isn't ctest just calling some commands | 08:28 |
| sonne|osx | ? | 08:28 |
| wiking | afaik yes | 08:28 |
| sonne|osx | so then it is easy | 08:28 |
| sonne|osx | a test returns 0 if it worked fine | 08:29 |
| sonne|osx | if not we can re-run the test with gdb | 08:29 |
| sonne|osx | and voila! | 08:29 |
| sonne|osx | this is how I did this when we had configure running | 08:30 |

| wiking | lambday: plz comment what you've find out about the mapping (works/does work) at: https://github.com/shogun-toolbox/shogun/issues/1493 | 11:32 |
| lambday | wiking: seems like I needed to add the sparse features thing after all, although it says features it actually works on sparse matrix | 11:32 |
| lambday | earlier I couldn't make it work | 11:32 |
| lambday | I added it | 11:32 |
| lambday | and now it works | 11:32 |
| lambday | SGVector<complex64_t> works perfectly by the way :) :) | 11:33 |
| lambday | thanks a lot man :) | 11:33 |
| wiking | ok | 11:33 |
| wiking | so u need sparsefeatures as well? | 11:33 |
| lambday | wiking: I will send a PR, with a few of my wrappers | 11:33 |
| lambday | wiking: actually, no.. I only needed SGSparseMatrix<complex64_t> to work | 11:34 |
| lambday | wiking: just a sec | 11:34 |
| wiking | lambday: that should work | 11:34 |
| wiking | although i have not tested it | 11:34 |
| wiking | ComplexSparseMatrix | 11:34 |
| lambday | wiking: https://github.com/shogun-toolbox/shogun/blob/develop/src/interfaces/python_modular/swig_typemaps.i#L1216 | 11:34 |
| wiking | ? | 11:35 |
| lambday | when I added TYPEMAP_SPARSEFEATURES_OUT(complex64_t, NPY_CDOUBLE), then it worked | 11:35 |
| wiking | before that? | 11:35 |
| lambday | didn't :( | 11:35 |
| lambday | the macro is for SGSparseMatrix | 11:36 |
| lambday | not CSparseFeatures | 11:36 |
| lambday | :( | 11:36 |
| wiking | In [1]: from modshogun import ComplexSparseMatrix | 11:36 |
| wiking | In [2]: x = ComplexSparseMatrix() | 11:36 |
| wiking | this works for me | 11:36 |
| wiking | w/o that line | 11:36 |
| wiking | make up your mind | 11:36 |
| wiking | do u need SparseMatrix | 11:36 |
| wiking | or SparseFeatures | 11:36 |
| lambday | wiking: but I tried to pass a csc_matrix(complex) as an argument to a class which takes SGSparseMatrix<complex64_t> it didn't work | 11:37 |
| lambday | I need sparse matrix | 11:37 |
| wiking | csc_matrix(complex)? | 11:37 |
| wiking | what's this? | 11:37 |
| lambday | that's scipy.sparse matrix... | 11:38 |
| lambday | for real types, I can seamlessly pass a csc_matrix to a shogun method that takes SGSparseMatrix<float64_t> | 11:38 |
| lambday | for complex, I needed the same | 11:38 |
| wiking | ok tell me the code that i can generate this scipy.sparse | 11:39 |
| wiking | csc_matrix(complex | 11:39 |
| lambday | wiking: wait.. | 11:39 |
| wiking | as you are talking way out of context | 11:39 |

| lambday | what I need is that, I need to pass that csc_matrix to my class | 11:43 |
| lambday | in the constructor | 11:43 |
| lambday | locally it works now | 11:44 |
| wiking | yeah | 11:44 |
| wiking | CSparseMatrixOperator needs a mapping as well | 11:44 |
| wiking | :) | 11:44 |
| lambday | wiking: yeah I added that locally | 11:44 |
| lambday | sending PR :) | 11:44 |
| wiking | but i dont know how you can set the values of ComplexSparseMatrix | 11:44 |
| wiking | :< | 11:44 |
| wiking | in fact i dont know how u do that with ComplexMatrix either | 11:44 |
| lambday | no idea! | 11:44 |
| wiking | :P | 11:44 |
| wiking | or RealMatrix | 11:45 |
| wiking | how do you convert a numpy.matrix -> RealMatrix | 11:45 |
| lambday | but if I pass a csc_matrix to a method that takes SGSparseMatrix as an arg, it works :D | 11:45 |
| wiking | or RealSparseMatrix | 11:45 |
| wiking | iglesiasg: btw i think it would be a good thing to enable director classes on that shogun install in the notebook server | 11:46 |
| @iglesiasg | wiking: using the image I guess, right? | 11:46 |
| lambday | wiking: I am using wrappers for these, so in the constructor I pass csc_matrix, works fine | 11:46 |
| wiking | iglesiasg: image? | 11:46 |
| wiking | iglesiasg: what image do you mean? | 11:46 |
| @iglesiasg | wiking: to test the notebooks | 11:46 |
| wiking | no comprende | 11:46 |
| @iglesiasg | haha | 11:47 |
| wiking | elaborate plz | 11:47 |
| wiking | :) | 11:47 |
| @iglesiasg | wiking: 11:41 < wiking> iglesiasg: well test it | 11:47 |
| wiking | iglesiasg: ah no | 11:47 |
| wiking | iglesiasg: haven't u received my email to shogun-team@ ? | 11:47 |
| @iglesiasg | nope | 11:47 |
| wiking | weeeeird | 11:47 |
| @iglesiasg | that was the part of | 11:47 |
| @iglesiasg | developers have been sent blah blah I did not get | 11:48 |
| @iglesiasg | but it might have missed it | 11:48 |
| @iglesiasg | let me double check... | 11:48 |
| wiking | ok let me know | 11:48 |
| wiking | maybe it's still in greylist | 11:48 |
| wiking | oooor i've sent from an address from which i'm not allowed to that list | 11:48 |
| wiking | oh ok | 11:49 |
| wiking | that's what happend | 11:49 |
| wiking | let me resend it | 11:49 |
| wiking | iglesiasg: sent again... let me know if u received now | 11:49 |
| @iglesiasg | wiking: received | 11:49 |
| wiking | cool | 11:49 |
| wiking | sorry about the fuckup | 11:49 |
| @iglesiasg | wiking: aah np | 11:51 |
| @iglesiasg | I love struggling with these little things :D | 11:51 |
| wiking | ah shiiit | 11:53 |
| wiking | we would need this | 11:53 |
| wiking | Magics for temporary workspace | 11:53 |
| wiking | https://github.com/tkf/ipython-tempmagic | 11:53 |
| @iglesiasg | testing the notebooks atm... | 11:53 |
| @iglesiasg | cool stuff | 11:53 |
| @iglesiasg | wiking: to ensure, so every time I run a cell | 11:53 |
| @iglesiasg | wiking: it is being executed in 7nn, right? | 11:54 |
| wiking | yesp | 11:54 |
| wiking | *yeps | 11:54 |
| @iglesiasg | sweet! | 11:54 |
| wiking | the problem is that currently | 11:54 |
| wiking | or not the problem | 11:54 |
| wiking | but the fact is | 11:54 |
| @iglesiasg | it is saved | 11:54 |
| wiking | that the directory where you enter (where the notebooks are) | 11:54 |
| wiking | is readonly | 11:54 |
| @iglesiasg | why problem? | 11:55 |
| @iglesiasg | drawback? | 11:55 |
| wiking | well | 11:55 |
| wiking | can u add a new notebook now? | 11:55 |
| wiking | 2013-09-20 09:50:58.338 [tornado.general] WARNING | 400 GET /new (91.64.72.127): Unexpected error while autosaving notebook: [Errno 30] Read-only file system: u'/home/notebook/notebooks/Untitled0.ipynb' | 11:55 |

| wiking | from the logs | 11:55 |
| wiking | so i suspect that u cannot add a new notebook | 11:55 |
| @iglesiasg | no.. I cant | 11:55 |
| wiking | see | 11:56 |
| wiking | that's the thing | 11:56 |
| @iglesiasg | 400: Bad Request | 11:56 |
| wiking | you can run the ones that are there | 11:56 |
| @iglesiasg | but hold on | 11:56 |
| wiking | but you cannot add a new one | 11:56 |
| @iglesiasg | how do we want to handle that? | 11:56 |
| @iglesiasg | I mean | 11:56 |
| wiking | well this magic shit | 11:56 |
| wiking | should be able to do that | 11:56 |
| wiking | creates a temp location | 11:56 |
| wiking | and there you can write whatever | 11:56 |
| @iglesiasg | do we want people coming in creating notebooks and keeping them in our server? | 11:56 |
| wiking | but then as soon as u log out | 11:56 |
| @iglesiasg | or just keeping them while they are logged in? | 11:56 |
| wiking | it's cleaned up | 11:57 |
| wiking | well | 11:57 |
| @iglesiasg | all right | 11:57 |
| wiking | it'd be interesting to keep some | 11:57 |
| wiking | i would say | 11:57 |
| @iglesiasg | that makes sense then | 11:57 |
| @iglesiasg | do you think so? | 11:57 |
| wiking | maybe somebody does some interesting stuff | 11:57 |
| wiking | but then again | 11:57 |
| wiking | that person can send it to us | 11:57 |
| @iglesiasg | mmm yeah it could be | 11:57 |
| wiking | since one can download the notebooks | 11:57 |
| @iglesiasg | we could train a classifier to keep the interesting ones :) | 11:57 |
| wiking | hehehe | 11:57 |
| wiking | but anyhow i think 2013-09-20 09:50:58.338 [tornado.general] WARNING | 400 GET /new (91.64.72.127): Unexpected error while autosaving notebook: [Errno 30] Read-only file system: u'/home/notebook/notebooks/Untitled0.ipynb' | 11:57 |
| wiking | so | 11:58 |
| wiking | i think that we should try to use this magic shit | 11:58 |
| wiking | but yeah test it and then send some feedbacks (this is not for you but *all*) and then i'll do the changes stilll | 11:58 |
| @iglesiasg | well I just realized that I need to update my notebook... | 11:59 |
| @iglesiasg | we deffs need to get custom data to the notebook somehow | 11:59 |
| @iglesiasg | wiking: btw, the first mail ipython notebook test mail you sent just arrived here xD | 12:00 |

| iglesiasg | sonne|work: hi! | 14:02 |
| sonne|work | hi | 14:02 |
| iglesiasg | have you checked the notebooks? | 14:02 |
| sonne|work | a bit | 14:02 |
| iglesiasg | wiking did some stuff and we can already execute them | 14:02 |
| iglesiasg | cool | 14:02 |
| iglesiasg | sonne|work: any thought regarding getting data into the notebook? | 14:03 |
| iglesiasg | I think we really need to provide that | 14:03 |
| iglesiasg | the API could look like | 14:04 |
| iglesiasg | features = RealFeatures(LocalFile('path/to/file/in/client/machine')) | 14:04 |
| iglesiasg | and the same for the labels | 14:05 |
| sonne|work | iglesiasg: we have that already | 14:05 |
| iglesiasg | oh really? | 14:05 |
| sonne|work | iglesiasg: see examples RealFeatures(CSVFile('/path/to/file')) | 14:05 |
| sonne|work | same with .h5 | 14:05 |
| sonne|work | and libsvm files | 14:05 |
| iglesiasg | sonne|work: yeah yeah | 14:05 |
| sonne|work | etc | 14:05 |
| iglesiasg | but the ipython runs in 7nn! | 14:05 |
| iglesiasg | so CSVFile('path/blahblah') | 14:06 |
| iglesiasg | would look in 7nn's FS | 14:06 |
| sonne|work | sure | 14:06 |
| iglesiasg | what I am thinking about is that someone using the notebook | 14:06 |
| iglesiasg | can choose what data to use from her machine | 14:06 |
| sonne|work | and then? | 14:07 |
| iglesiasg | ? | 14:08 |
| iglesiasg | well then she can do stuff in the notebook with that data | 14:08 |
| sonne|work | what does he do if he has chosen some data | 14:08 |
| sonne|work | that doesn't explain how to get the data | 14:08 |
| sonne|work | to fatbot | 14:08 |
| iglesiasg | yeah that's why I said API :) | 14:09 |
| sonne|work | no idea what you say :/ | 14:09 |
| sonne|work | what does features = RealFeatures(LocalFile('path/to/file/in/client/machine')) do | 14:10 |
| sonne|work | where is this run? | 14:10 |
| iglesiasg | LocalFile does stuff under the hood | 14:11 |
| iglesiasg | sends the file | 14:11 |
| iglesiasg | makes security checks | 14:11 |
| iglesiasg | cheks for format | 14:11 |
| iglesiasg | and finally load it in numpy array if everthing went fine | 14:12 |
| sonne|work | iglesiasg: well this is maybe 2 lines python then | 14:13 |
| iglesiasg | sonne|work: even better then | 14:14 |
| sonne|work | import urllib2 | 14:14 |

| sonne|work | http://somewhere.where/the/file/is | 14:15 |
| iglesiasg | I guess that file:/// ... won't work | 14:16 |

| @HeikoS | wiking: nice! just tried the could shogun :) aweseom! | 15:24 |
| @iglesiasg | HeikoS: so in the example evaluation_cross_validation_classification.py | 15:30 |
| @iglesiasg | HeikoS: it says that StratifiedCrossValidation is better | 15:31 |
| @HeikoS | yes | 15:31 |
| @iglesiasg | but standard StratifiedCrossValidatoinSplitting is also available | 15:31 |
| @iglesiasg | I don't quite a get it | 15:31 |
| @HeikoS | you mean CrossValidationSplitting | 15:31 |
| @iglesiasg | ok | 15:31 |
| @HeikoS | sometimes one cannot do stratified | 15:31 |
| @iglesiasg | then you meant that :P | 15:31 |
| @HeikoS | for example in regression | 15:31 |
| @iglesiasg | I will update the example | 15:31 |
| @HeikoS | stratified should always be used with classification | 15:31 |
| @HeikoS | actually, we could think about doing something similar to stratified for regression, (grouping y values) but that would be later | 15:32 |
| @HeikoS | iglesiasg: cool thanks! | 15:32 |
| @iglesiasg | oh I see | 15:32 |
| @iglesiasg | I guess this regression thing is related (though not limited) to GPs, right? | 15:32 |

| @HeikoS | so that one only has to add it if modelselection is available | 18:17 |
| @HeikoS | but no need to change that now | 18:17 |
| @HeikoS | votjakovr: pls dont do all these whitespace changes, makes it hard to look through PRs | 18:17 |
| votjakovr | HeikoS: yep, i know, sorry | 18:17 |
| @iglesiasg | HeikoS: will take a look at LMNN again | 18:18 |
| @iglesiasg | can it be that it was for a commit where develop was not rebased? | 18:19 |
| @iglesiasg | gtg now | 18:19 |
| @iglesiasg | but will check later | 18:19 |
| @HeikoS | iglesiasg: I dont know, but then this is on travis since its not possible to merge otherwise | 18:20 |

| @HeikoS | votjakovr: what is missing now? | 18:44 |
| @HeikoS | votjakovr: I will be away on the weekend, can maybe help a bit with the notebook on late Sat or Sun, but I need your initial draft for that | 18:45 |
| @HeikoS | votjakovr: its impossible for me to read through all of these changes, especially since there so many unreleated changes, so what are you working on currently? | 18:45 |
| votjakovr | HeikoS: i'm still working on CParameterCombination | 18:48 |
| @HeikoS | votjakovr: whats after that? | 18:48 |
| votjakovr | HeikoS: gradient model selection will be working | 18:48 |
| votjakovr | HeikoS: then notebook | 18:49 |
| @HeikoS | votjakovr: okay nice, I just skipped though the PR, seems al ok | 18:49 |
| @HeikoS | votjakovr: but the problem is I cannot read this properly since my browser can't handle such a large page ;) | 18:49 |

| @HeikoS | votjakovr: so let me know when the thing is final and all tests pass ( I will have alook into the tests then) and then OK for merge | 18:50 |
| @HeikoS | I will be around for another 2hrs | 18:50 |
| @HeikoS | votjakovr: what the time schedule you have? | 18:50 |
| @HeikoS | votjakovr: actually travis passed | 18:50 |
| votjakovr | HeikoS: cool, i'd like to work until model selection is done | 18:51 |
| @HeikoS | okay | 18:52 |
| @HeikoS | votjakovr: so I will update your notebook a bit on Sun then | 18:52 |
| @HeikoS | votjakovr: let me know how the state is in 1-2 hrs ok? | 18:52 |
| votjakovr | HeikoS: ok, about examples: i drop them, because they are using old gradient model selection | 18:53 |
| votjakovr | HeikoS: it's not a problem to back them | 18:53 |
| @HeikoS | votjakovr: I see, then pls rather deactivate them for now | 18:53 |
| @HeikoS | since all these method need to be illustrated atsome point | 18:54 |
| @HeikoS | just do something like #ifdef 0 | 18:54 |
| @HeikoS | and add a comment that they are currently disabled due to api changes but soon coming again | 18:54 |
| votjakovr | HeikoS: ok, i'll do | 18:54 |

| @HeikoS | lambday: ok let me know | 19:09 |
| @HeikoS | nothing there yet | 19:09 |
| lambday | HeikoS: just a few things.. incorporating the rest of the things | 19:13 |
| @HeikoS | lambday: okay, keep in mind that these are just suggestions :) | 19:13 |
| lambday | HeikoS: yeah but this will make it look cool :) | 19:13 |
| lambday | HeikoS: how do I display the cholesky factors? using cholmod? | 19:14 |
| lambday | using shogun I cannot do that | 19:14 |
| @HeikoS | lambday: turn the matrix into dense and compute dense cholesky | 19:15 |
| @HeikoS | for the small one, that should work | 19:15 |
| lambday | HeikoS: so, for west0479 I can do that | 19:16 |
| lambday | and you want the putting it all together part pulled above | 19:16 |
| @HeikoS | lambday: yeah exactly | 19:16 |
| @HeikoS | lambday: yeah I think so | 19:16 |
| @HeikoS | all these solvers are not crucial for using the method | 19:16 |
| lambday | nah | 19:16 |
| @HeikoS | more like an illustration how to use the tools you created | 19:17 |
| lambday | yes | 19:17 |
| lambday | alright.. | 19:17 |
| @HeikoS | you can introduce that as "All the methods needed to estimate the log-determinants in the above way can also be used on their own | 19:17 |
| lambday | ah that sounds great' | 19:17 |
| lambday | HeikoS: oh one thing.. I didn't get that part when you said that the matrix I used for CG may not be psd | 19:18 |
| lambday | I already did m^Tm+I | 19:18 |
| lambday | and applied cg on that one | 19:18 |
| @HeikoS | ah | 19:18 |
| @HeikoS | maybe I missed that | 19:18 |
| @HeikoS | sorry then | 19:18 |
| lambday | where m is randomly generated | 19:18 |
| lambday | HeikoS: np.. oh and where would these notebooks go? (so that I can put a relative path to the data, gotta add apache2 and ozone though) | 19:19 |
| @HeikoS | there is a directory for them ... | 19:19 |
| @HeikoS | in doc | 19:20 |
| lambday | HeikoS: doc/ipython-notebooks | 19:20 |
| lambday | found it | 19:20 |
| lambday | LD | 19:20 |
| lambday | :D | 19:20 |
| @HeikoS | lambday: just respect the directory structure for yours | 19:20 |
| lambday | alright | 19:21 |
| lambday | HeikoS: I wanted to add something for the ozone mcmc | 19:21 |
| lambday | HeikoS: oh and one more thing... combining the normal and probing samplers is exactly what I did earlier | 19:21 |
| lambday | HeikoS: but probing samplers have so less variance,that when I put it with Normal, it almost looks aligned with the actual logdet | 19:22 |
| @HeikoS | lambday: I see | 19:22 |
| lambday | that's why kept these two separate | 19:22 |
| lambday | :-/ | 19:22 |
| @HeikoS | then do subplot(121) #plot normal subplot(122) #plot probing | 19:22 |
| @HeikoS | just do have them next to each other | 19:22 |
| @HeikoS | and plot histograms on top of each other | 19:23 |
| @HeikoS | would be cool to have a histogram like on the poster | 19:23 |
| @HeikoS | with both samples and the true value | 19:23 |
| lambday | HeikoS: alright | 19:23 |
| lambday | still new to this matplotlib, fighting a bit :-/ | 19:23 |
| lambday | HeikoS: can I add external images (that are not generated plots from the code) in the notebook? | 19:24 |
| @HeikoS | lambday: yes, but why do you want to do that? | 19:24 |
| @HeikoS | lambday: ask me if you have problems with plotting | 19:24 |
| lambday | HeikoS: I wanted to put a CG-M convergence plot based on the residuals | 19:24 |
| @HeikoS | lambday: can you actually access the residuals? | 19:25 |
| @HeikoS | lambday: thats a nice idea in fact | 19:25 |
| @HeikoS | Cant you do that for a small matrix, extract the residuals and then just plot? | 19:25 |
| lambday | HeikoS: externally, run the c++ in debug more, collect the residuals (thanks to you) | 19:25 |
| lambday | HeikoS: how can I externally insert an image to a notebook.. it works locally, but while uploading it in the gist to the nbviewer, I don't find an option to upload any image | 19:26 |
| @HeikoS | lambday: I dont like this so much with the external picture | 19:27 |
| @HeikoS | lambday: though I like the idea about plotting convergence | 19:27 |
| lambday | HeikoS: then I have to add something in the solvers itself to store the residuals :-/ | 19:27 |
| @HeikoS | lambday: yeah, in fact that is useful | 19:28 |
| @HeikoS | lambday: but it should be off by default | 19:28 |
| lambday | HeikoS: is it :-/ | 19:28 |
| lambday | alright | 19:28 |
| @HeikoS | lambday: yes, in cases one is interested in acessing residuals | 19:28 |
| besser82 | HeikoS, wiking, sonne|work: Anyone of you interested in adding ViennaCL-support to SHOGUN? | 19:28 |
| @HeikoS | lambday: can this be done once? and then used form all solvers? | 19:28 |
| lambday | HeikoS: alright then | 19:28 |
| @HeikoS | lambday: but maybe do other things first | 19:28 |
| @HeikoS | lambday: its not too important | 19:28 |
| @HeikoS | lambday: but the external picture is not really useful if there is not code how to generate it | 19:29 |
| lambday | HeikoS: could you please explain a bit regarding the ozone model | 19:29 |
| @HeikoS | and since convergence diagnostics are always useful, should be in there | 19:29 |
| lambday | HeikoS: yeah I understand | 19:29 |
| @HeikoS | lambday: ok, what to explain? | 19:29 |
| lambday | HeikoS: I didn't get what these matrices represent? | 19:29 |
| lambday | GiCG, C0, G A | 19:29 |
| @HeikoS | besser82: maybe at some point :) | 19:30 |
| @HeikoS | besser82: would be cool to have these kind of backend | 19:30 |
| @HeikoS | besser82: though we are currently heavily using eigen3 | 19:30 |
| @HeikoS | lambday: ah | 19:30 |
| @HeikoS | lambday: thats not too important, it is the model | 19:30 |
| @HeikoS | so A is a piecewise linear triangulation of a sphere (the globe) | 19:30 |
| lambday | (with Q, we are not even using A, right?) | 19:31 |
| @HeikoS | it takes the latent gaussian field of the model (which lives on a sphere) and maps it to a plane | 19:31 |
| @HeikoS | lambday: there are two log-dets in the log likelihood | 19:31 |
| @HeikoS | once involves A^T A | 19:31 |
| besser82 | HeikoS, wiking, sonne|work: GTX285-SLI would slightly outperform recent Xeons, but on affordable $. :) | 19:31 |
| -!- FSCV_ [~FSCV@187.191.50.146] has quit [Quit: Leaving] | 19:31 | |
| besser82 | HeikoS: eigenvector runs really speedy on ViennaCL. Just tried :) | 19:32 |
| @HeikoS | besser82: thats really nice, but the problem is all the interfacing | 19:32 |
| @HeikoS | besser82: we dont want to change everything again, just moved to eigen3 | 19:32 |
| @HeikoS | if eigen3 had a backend like that, that would be coo | 19:32 |
| @HeikoS | cool | 19:32 |
| @HeikoS | and is rather the way to go | 19:33 |
| @HeikoS | ah I just see there is eigen stuff in there | 19:33 |
| besser82 | HeikoS: wouldn't be much for eigen3 --> ViennaCL. ViennaCL has interface for eigen3 :) | 19:33 |
| @HeikoS | besser82: so that might be an idea | 19:33 |
| @HeikoS | yep, that sounds cool | 19:33 |
| -!- van51 [~van51@athedsl-409794.home.otenet.gr] has joined #shogun | 19:33 | |
| @HeikoS | besser82: maybe a gsoc project or so :) | 19:33 |
| lambday | what's ViennaCL? | 19:34 |
| @HeikoS | lambday: dont worry for now :) but here http://viennacl.sourceforge.net/viennacl-about.html | 19:34 |
| besser82 | lambday: ViennaCL is BLAS, LAPACK/ATLAS, eigen3 on OpenCL/CUDA :) | 19:34 |
| lambday | HeikoS: just curious :D | 19:34 |
| @HeikoS | lambday: so you could add a little section before or after the tools section | 19:34 |
| @HeikoS | which states the ozone model | 19:35 |
| lambday | HeikoS: tools? | 19:35 |
| @HeikoS | solvers etc | 19:35 |
| @HeikoS | and kind of motivates why we need the log-determinants | 19:35 |
| @HeikoS | and then runs the thing with very low max iterations | 19:35 |
| @HeikoS | to illustrate that it works on desktop computers | 19:35 |
| lambday | HeikoS: why we need log-determinants --- is coming from the requirement of computing the log-likelihood itself, right? | 19:36 |
| lambday | HeikoS: sorry I am not getting what you mean here :( | 19:36 |
| -!- sonne|osx [~sonne@f053037117.adsl.alicedsl.de] has joined #shogun | 19:36 | |
| @HeikoS | lambday: exactly, every GMRF needs log.determinants | 19:36 |
| @HeikoS | in fact every Gaussian distribution | 19:36 |

| lambday | HeikoS: yes | 19:37 |
| lambday | darn you cyg1 :'( | 19:37 |
| @HeikoS | but the precision matrix is sparse in every GMRF | 19:37 |
| @HeikoS | so thats just an example | 19:37 |
| @HeikoS | you can point to the Aune et al paper | 19:37 |
| @HeikoS | or even to this one | 19:37 |
| lambday | besser82: sounds really interesting | 19:38 |
| lambday | :D | 19:38 |
| lambday | besser82: I have no clue regarding the last two OpenCL/.CUDA :D | 19:38 |
| lambday | HeikoS: :-/ | 19:38 |
| @HeikoS | http://arxiv.org/pdf/1104.3436.pdf | 19:39 |
| @HeikoS | page 22 bottom | 19:39 |
| @HeikoS | you could reference this | 19:39 |
| besser82 | lambday: it surely is. openCL / CUDA is distributed computing using your GPU for performing. | 19:39 |
| lambday | HeikoS: checking | 19:39 |
| besser82 | lambday: CUDA is sth. specific to nvidia-cards | 19:39 |
| @HeikoS | besser82: this stuff is only interesting if existing libraries do this in the back | 19:39 |
| @HeikoS | besser82: otherwise its way too technical to use | 19:40 |
| @HeikoS | besser82: i played with GPUs a bit a few years ago | 19:40 |
| @HeikoS | and without std libs this is pure horror ;= | 19:40 |
| besser82 | HeikoS: ViennaCL should give simple interfaces to use for sci-tech tasks :) | 19:40 |
| @HeikoS | besser82: so if we can keep our eigen3 calls as they are and just do some magic in the background, I am really up for this! | 19:41 |
| besser82 | HeikoS: http://viennacl.sourceforge.net/viennacl-examples-eigen.html | 19:41 |
| besser82 | HeikoS: nothing much to change :) | 19:41 |
| lambday | HeikoS: I need to study :-/ what are these parameters :-/ | 19:41 |
| lambday | HeikoS: I thought giving only your paper as reference for ozone | 19:42 |
| @HeikoS | lambday: so, what I suggest, is just to state the model (as in the poster), mention the log-likelihood, and then show that one can compute the likelihood using shogun | 19:42 |
| @HeikoS | lambday: https://github.com/karlnapf/ozone-roulette/blob/master/ozone/distribution/OzonePosterior.py | 19:43 |
| @HeikoS | just take the log_likelihood method and use log_det_estimate_shogun and solve_sparse_linear_system_shogun | 19:43 |
| lambday | HeikoS: and the outputs/images? | 19:44 |
| lambday | oh okay | 19:44 |
| @HeikoS | and say that for illustration, you only estimate the log-det but solve the linear system with cholesky | 19:44 |
| besser82 | HeikoS: so just copying in/out eigen3-datatypes and performing tasks on them. | 19:44 |
| @HeikoS | lambday: images would be nice | 19:44 |
| @HeikoS | lambday: the plotting code is in matlab though, let me check how we can get the map | 19:44 |
| lambday | HeikoS: no no.. I only want to put that much part that I myself understand :( | 19:46 |
| @HeikoS | lambday: ok then, just state the model, it has an easy form since it is a std model, it just looks technical | 19:47 |
| @HeikoS | so if you tell the distributions of x, y|y, tau, kappa, and then state the log-likelihood that is ok | 19:47 |
| @HeikoS | and then you can plot y if you want | 19:47 |
| @HeikoS | lambday: just if you want of course | 19:47 |
| @HeikoS | lambday: ill send you code to plot the observations of the ozone model | 19:47 |
| lambday | HeikoS: ah thanks.. :) | 19:48 |
| @HeikoS | lambday: the idea here is that you just say: "Here is a sparse Gaussian model for which this stuff is useful" | 19:48 |
| lambday | yes | 19:48 |
| @HeikoS | and the likelihood function in the file I sent you is just directly turning the log-likelihood math into numbers, no tricks there | 19:48 |

| lambday | HeikoS: the log_likelihood method in the OzonePosterior? | 19:50 |
| @HeikoS | yes | 19:50 |
| @HeikoS | lambday: check it, it just computes the log-likelihood on the poster | 19:50 |
| @HeikoS | lambday: I have not plotting code in python and its non-trivial to plot | 19:54 |
| @HeikoS | lambday: thinking on what to do .... | 19:54 |
| lambday | HeikoS: let's chuck it | 19:54 |
| lambday | HeikoS: I'll add these things later on this notebook when I'll work on more on this.. | 19:54 |
| @HeikoS | lambday: okay | 19:55 |
| lambday | HeikoS: I really liked the issues that you posted, parallel computation engine and one other | 19:55 |
| lambday | HeikoS: I would like to work on that | 19:55 |

| @HeikoS | lambday: but I think it still would be nice to say: Here is a std GMRF model and its log likelihood. Here we load some ozone data, see reference paper, and here we can compute the log-likelihood | 19:56 |
| @HeikoS | lambday: its ultra cool even without images | 19:56 |
| @HeikoS | so I would totally suggest to add that | 19:56 |
| lambday | HeikoS: so, computing the likelihood thing, I can use your code? :D | 19:56 |
| @HeikoS | lambday: yeah sure | 19:56 |
| @HeikoS | its GPL :) | 19:57 |
| lambday | hehe | 19:57 |
| lambday | alright | 19:57 |
| lambday | yeah it would be really cool | 19:57 |
| lambday | so, the structure would be ---intro --- log-det on apache2, walking through the components --- ozone --reference | 19:58 |
| lambday | not just apache2, but also west0479 | 19:58 |
| lambday | with fill-in | 19:58 |

| @iglesiasg | sonney2k, lisitsyn ping ping | 21:39 |
| lisitsyn | ja | 21:39 |
| lisitsyn | iglesiasg: hello | 21:39 |
| @iglesiasg | lisitsyn, how are you? | 21:39 |
| lisitsyn | iglesiasg: fine | 21:39 |
| lisitsyn | iglesiasg: what about you? | 21:39 |
| @iglesiasg | LMNN is giving headache :D | 21:39 |
| lisitsyn | iglesiasg: what's with it? | 21:39 |
| @iglesiasg | https://travis-ci.org/shogun-toolbox/shogun/jobs/11599254#L4772 | 21:39 |
| @iglesiasg | integration test | 21:40 |
| @iglesiasg | the 16th decimal or so is different :D | 21:40 |
| lisitsyn | hah | 21:40 |
| @iglesiasg | lisitsyn, can that be Eigen related? | 21:41 |
| lisitsyn | iglesiasg: no clue :) | 21:41 |
| lisitsyn | iglesiasg: is that ok accuracy? | 21:42 |
| lisitsyn | I mean 16th sign is a bit too much | 21:42 |
| lisitsyn | but who knows | 21:43 |
| @iglesiasg | lisitsyn, a bit too much? | 21:43 |
| @iglesiasg | I think the difference is insignificant | 21:43 |
| lisitsyn | iglesiasg: looks too precise | 21:43 |
| @iglesiasg | lisitsyn, I have just run it more than 100 times here in my machine and it is always OK. | 21:49 |
| @iglesiasg | lisitsyn, I guess I could just deactivate de integration test | 21:49 |
| lisitsyn | iglesiasg: I am not sure what to do about it | 21:50 |
| @iglesiasg | some of the parts are already tested in unit tests | 21:50 |
| @iglesiasg | it is fine in the buildbot as well | 21:51 |
| sonne|osx | lisitsyn: please disable integration tests on travis | 21:53 |
| sonne|osx | it is sufficient to have this on the buildbots | 21:54 |
| lisitsyn | sonne|osx: | 21:54 |
| lisitsyn | ok | 21:54 |
| @iglesiasg | I like that initiative! | 21:54 |
| @iglesiasg | thank you guys | 21:54 |
| lisitsyn | I like to disable/delete | 21:54 |
| lisitsyn | :D | 21:54 |
| sonne|osx | lisitsyn: can you do the gdb thing? | 21:58 |
| lisitsyn | sonne|osx: yes | 21:58 |
| sonne|osx | lisitsyn: https://github.com/shogun-toolbox/shogun/issues/1643 | 21:58 |
| lisitsyn | I am on it just after integration tests | 21:58 |
| sonne|osx | this would help *a lot* to fix e.g. cyg1 | 21:58 |

| @iglesiasg | lisitsyn, how is your German going? :) | 22:08 |
| lisitsyn | iglesiasg: schlecht | 22:08 |
| * iglesiasg translates | 22:08 | |
| @iglesiasg | hehe why so? | 22:08 |
| lisitsyn | iglesiasg: well I am having some time management troubles | 22:13 |
| lisitsyn | ;) | 22:13 |

| lisitsyn | oh gosh wiking you have done crazy amount of work with cmake | 22:40 |
| besser82 | lisitsyn: araound? | 22:40 |
| lisitsyn | besser82: yes what's up? | 22:40 |
| besser82 | lisitsyn: I've seen you're adding ViennaCL to tapkee... | 22:41 |
| lisitsyn | besser82: I've made some experiments | 22:41 |
| besser82 | lisitsyn: Any motivation to bring this up to SHOGN? | 22:41 |
| lisitsyn | besser82: well I should update tapkee in shogun yeah | 22:41 |
| lisitsyn | besser82: the problem is that speedup is not really worth the game | 22:42 |
| besser82 | lisitsyn: for tapkee or shogun? | 22:42 |
| lisitsyn | besser82: the only thing I have seen is some 1.5x speedup with diffusion maps | 22:42 |
| lisitsyn | besser82: for shogun it makes sense | 22:42 |
| lisitsyn | but needs proper design | 22:43 |
| besser82 | lisitsyn: eigenvectors do get really fast with it :) | 22:43 |
| lisitsyn | besser82: dense? | 22:43 |
| besser82 | lisitsyn: both sparse and dense | 22:43 |
| lisitsyn | besser82: full eigendecomposition? | 22:43 |
| besser82 | lisitsyn: not tried yet | 22:43 |
| lisitsyn | besser82: I mean is it full or partial? | 22:43 |
| besser82 | lisitsyn: should be full | 22:44 |
| lisitsyn | besser82: that's the critical point because in tapkee full eigendecomposition is never used | 22:44 |
| lisitsyn | say you are computing LLE embedding | 22:44 |
| lisitsyn | you have N x N sparse matrix | 22:44 |
| lisitsyn | but to compute 2d embedding you need *only* 3 smallest eigenvectors | 22:44 |
| shogun-buildbot | build #1510 of cyg1 - libshogun is complete: Failure [failed test] Build details are at http://buildbot.shogun-toolbox.org/builders/cyg1%20-%20libshogun/builds/1510 blamelist: Sergey Lisitsyn <lisitsyn.s.o@gmail.com> | 22:45 |
| besser82 | lisitsyn: so partial... | 22:45 |
| lisitsyn | yeah so I need partial | 22:45 |
| lisitsyn | that's why I am tied to arpack :) | 22:45 |
| besser82 | lisitsyn: but ViennaCL should support both | 22:45 |
| lisitsyn | let me check | 22:45 |
| lisitsyn | I don't mind to put it if it is here | 22:45 |
| lisitsyn | I tried to make it modular | 22:45 |
| lisitsyn | besser82: true, lanczos is here | 22:46 |
| besser82 | lisitsyn: :D | 22:46 |
| lisitsyn | besser82: ah one more problem - I don't have any gpu ;) | 22:47 |
| besser82 | lisitsyn: pocl is your freind :) | 22:47 |
| besser82 | lisitsyn: pocl is openCL on cpu only :) | 22:47 |
| lisitsyn | besser82: well no, my cpu supports opencl natively | 22:47 |
| lisitsyn | that's sandy bridge | 22:47 |
| lisitsyn | but hey that's essentially the same | 22:47 |
| lisitsyn | I mean I can't see the speedup | 22:47 |
| besser82 | lisitsyn: because of no GPU :) | 22:48 |
| besser82 | lisitsyn: GTX285 SLI nearly oupterforms recent XEON !!! | 22:48 |
| besser82 | lisitsyn: and is really affordable $ | 22:48 |
| lisitsyn | besser82: okay thanks for the tip, I'll try to put lanczos to tapkee | 22:48 |
| besser82 | lisitsyn: :D | 22:48 |
| lisitsyn | besser82: well I am kind of mobile so I used to use notebook | 22:49 |
| lisitsyn | I am switching cities sometimes :D | 22:49 |
| lisitsyn | like today | 22:49 |
| besser82 | lisitsyn: me, too. But mine has GTX580 SLI :D | 22:49 |
| besser82 | lisitsyn: in notebook :D | 22:49 |
| lisitsyn | besser82: .. and your notebook weights like 8 kg I guess ;) | 22:50 |
| besser82 | lisitsyn: nope ~5 kg :) | 22:50 |
| lisitsyn | oh damn | 22:50 |
| besser82 | but with 17" screen :D | 22:50 |
| besser82 | and 3 HDD | 22:50 |
| besser82 | if i need ultra-mobility i use my old q45 from samsung ---> ~1.5 kg | 22:51 |
| lisitsyn | well you can save some money on fitness carrying tihs bag of potato | 22:51 |
| lisitsyn | :D | 22:51 |
| besser82 | sure :D | 22:51 |
| lisitsyn | besser82: anyway I just don't need gpu computing | 22:52 |
| lisitsyn | that's the main reason | 22:52 |
| lisitsyn | :) | 22:52 |
| besser82 | if you don't need then all is fine :) | 22:52 |
| lisitsyn | I played with it out of curiousity but it doesn't look I need it | 22:52 |
| besser82 | but in shogun | 22:52 |
| besser82 | it would be a real option :D | 22:52 |
| lisitsyn | I don't mind to spend some time on that if there is real demand | 22:53 |
| besser82 | combined with sth. like openShift I it would be great... | 22:53 |
| -!- zxtx [~zv@149.165.244.2] has quit [Ping timeout: 240 seconds] | 22:53 | |
| lisitsyn | besser82: I see a few problems there | 22:53 |
| besser82 | lisitsyn: which? | 22:54 |
| lisitsyn | 1) I don't know how to design heterogeneous software | 22:54 |
| lisitsyn | 2) I don't know how to deal with limited memory here | 22:54 |
| lisitsyn | I mean say you have kernel svm | 22:54 |
| lisitsyn | you need to have all the features in gpu memory | 22:54 |
| lisitsyn | otherwise you'll spend most of the time copying stuff back and forth | 22:55 |
| besser82 | won't 1.5 Gbytes be enough? | 22:55 |
| lisitsyn | besser82: 1.5gb seem to be enough yeah | 22:55 |
| shogun-buildbot | build #18 of debian wheezy - memcheck is complete: Failure [failed compile] Build details are at http://buildbot.shogun-toolbox.org/builders/debian%20wheezy%20-%20memcheck/builds/18 blamelist: Sergey Lisitsyn <lisitsyn.s.o@gmail.com> | 22:55 |
| besser82 | lisitsyn: any recent gtx285+ has at least 1gig | 22:56 |
| lisitsyn | oh I have no clue about these numbers ;) | 22:56 |
| lisitsyn | well yeah 1gb should be ok | 22:56 |
| besser82 | lisitsyn: gtx285 is from ~ 4years ago ;) | 22:56 |
| besser82 | lisitsyn: today's GTX{5,6,7,8}** are all <= 2Bytes of mem | 22:57 |
| lisitsyn | besser82: I haven't had any non-notebook computer nearly the same time | 22:57 |
| besser82 | lisitsyn: today's GTX{5,6,7,8}** are all >= 2Bytes of mem | 22:57 |
| lisitsyn | like once I started my studies | 22:57 |
| lisitsyn | heh | 22:57 |
| besser82 | desktops have these specs as well | 22:58 |
| lisitsyn | besser82: I have to get back to the fact I don't need it :D | 22:58 |
| besser82 | lisitsyn: ok, ok :D | 22:58 |
| lisitsyn | besser82: but if I get some hardware like that I'll try it for sure | 22:58 |
| lisitsyn | besser82: we should employ gpu to compile shogun to make it fast :D | 23:06 |
| besser82 | lisitsyn: using gpu on compiling or compiling with support for gpu-use? | 23:07 |
| lisitsyn | besser82: jk :) it is so slow | 23:08 |
| besser82 | lisitsyn: jk? | 23:08 |
| lisitsyn | besser82: just kidding | 23:08 |
| besser82 | lisitsyn: kk | 23:08 |
| besser82 | lisitsyn: but compiling isn't that slow takes ~7 minutes | 23:09 |
| besser82 | lisitsyn: try compiling Mahout :D | 23:09 |
| besser82 | lisitsyn: will run ~40 minutes on i7 | 23:09 |
| lisitsyn | besser82: really? | 23:12 |
| besser82 | lisitsyn: yes | 23:12 |
| lisitsyn | besser82: but its java, how can it be that slow? | 23:13 |
| lisitsyn | I am totally surprised | 23:14 |
| besser82 | lisitsyn: because of maven | 23:14 |
| besser82 | lisitsyn: hadoop takes ~1h | 23:14 |
| lisitsyn | besser82: what makes it that slow with maven? | 23:14 |
| besser82 | lisitsyn: not sure... | 23:15 |
| besser82 | lisitsyn: no idea | 23:15 |
| lisitsyn | besser82: sounds so weird! | 23:15 |
| lisitsyn | I am really surprised because I was used to think java = rather fast compilation | 23:15 |
| besser82 | lisitsyn: not even close :D | 23:16 |
| lisitsyn | C++ is terribly slow when it comes to expression templates like in eigen3 | 23:16 |
| besser82 | lisitsyn: that's true, but java is always slow :) | 23:17 |
| lisitsyn | well at my job we have quite good performance with java | 23:18 |
| lisitsyn | we are heavily using message passing with akka and I can't say it is slow | 23:18 |
| lisitsyn | well and I used to compile terribly big modules at my previous job and it was ok too | 23:19 |
| lisitsyn | that's why I am surprised | 23:19 |
| besser82 | lisitsyn: I really don't know what the apache-people did to it, making it that slow :( | 23:20 |
| lisitsyn | besser82: when I hear apache I think of cemetary | 23:20 |
| lisitsyn | like they have zillions of dead projects | 23:21 |
| besser82 | lisitsyn: but Mahout is one of the recent ones :) still in beta | 23:21 |
| besser82 | lisitsyn: or RC now | 23:21 |
| lisitsyn | yeah that's not dead | 23:21 |
| lisitsyn | I have used http://commons.apache.org/proper/commons-scxml/ | 23:22 |
| lisitsyn | but I didn't know what to think with last commit in ~2007 | 23:22 |
| lisitsyn | sonne|osx: did you mean both integration and unit tests? | 23:27 |
