| @sonney2k | gsomix_, I am thinking about using C_ORDER per default | 00:16 |
|---|---|---|
| @sonney2k | gsomix_, with csv data it is most likely that one has one vector per line | 00:17 |
| @sonney2k | (C_ORDER) | 00:17 |
| @sonney2k | IIRC there is the .tcsv format | 00:17 |
| -!- zxtx [~zv@c-98-207-60-193.hsd1.ca.comcast.net] has joined #shogun | 00:17 | |

| lisitsyn | hey HeikoS | 18:13 |
| @HeikoS | lisitsyn: hi! | 18:14 |
| lisitsyn | HeikoS: how is it going? | 18:14 |
| @HeikoS | well :) | 18:14 |
| @HeikoS | and you? | 18:14 |
| lisitsyn | yeah fine too | 18:14 |
| lisitsyn | HeikoS: I am still debugging this thing that fails in python :) | 18:14 |
| @HeikoS | lisitsyn: is that a hard one? | 18:15 |
| @HeikoS | lisitsyn: oh btw do the tests work fine on your machine on current git? | 18:15 |
| lisitsyn | HeikoS: yeah IIRC it worked yesterday | 18:15 |
| lisitsyn | HeikoS: what fails on your machine? | 18:15 |
| @HeikoS | lisitsyn: ok good | 18:15 |
| @HeikoS | lisitsyn: nothing, but travis seems to freeze and fernando also had a problem with my latest commit | 18:15 |
| lisitsyn | HeikoS: I was surprised with the number of tests | 18:16 |
| @HeikoS | lisitsyn: where? | 18:16 |
| lisitsyn | HeikoS: the total number | 18:17 |
| lisitsyn | like 11** | 18:17 |
| @HeikoS | lisitsyn: well half of it is created automagic | 18:17 |
| lisitsyn | yeah | 18:17 |
| @HeikoS | lisitsyn: but still good | 18:17 |
| @HeikoS | we test things on every class | 18:17 |
| @HeikoS | lisitsyn: still I would like to take this a step further in the near future | 18:17 |
| @HeikoS | make serialisation/clone/equals 100% reliable | 18:18 |
| @HeikoS | currently its only tested on empty classes | 18:18 |
| lisitsyn | HeikoS: what about migration and etc? | 18:18 |
| @HeikoS | lisitsyn: I am for dropping that (and the integration tests with it) since we cannot really maintain it. But open for discussions | 18:19 |
| lisitsyn | HeikoS: the only one that can maintain it is you probably | 18:20 |
| @HeikoS | lisitsyn: and I fail miserably ;) | 18:20 |
| @HeikoS | lisitsyn: the code is too complicated, too dirty, not tested etc | 18:20 |
| lisitsyn | no you are doing other things | 18:20 |
| lisitsyn | that are more important | 18:20 |
| @HeikoS | lisitsyn: it is extremely hard to use | 18:20 |
| @HeikoS | lisitsyn: and nobody really uses that parts that work | 18:20 |
| @HeikoS | lisitsyn: rather, we always re-commit the integration tests | 18:20 |
| @HeikoS | lisitsyn: well thats the same result, I dont think an open-source project focussed on ML can offer migration for its fil format | 18:21 |
| lisitsyn | HeikoS: hehe that's true everybody should do their job | 18:22 |
| @HeikoS | lisitsyn: how are things going with you? | 18:22 |
| lisitsyn | HeikoS: I feel we are maintaining a bit more than we should | 18:22 |
| @HeikoS | lisitsyn: yeah maybe | 18:23 |
| @HeikoS | lisitsyn: see my issues on dropping code | 18:23 |
| lisitsyn | HeikoS: what things? | 18:23 |
| @HeikoS | marking stable things, etc | 18:23 |
| @HeikoS | lisitsyn: work, shogun etc | 18:23 |
| @HeikoS | gsoc | 18:23 |
| lisitsyn | ahh | 18:23 |
| lisitsyn | we had some failure at my job and I moved to a new place | 18:23 |
| lisitsyn | :D | 18:23 |
| @HeikoS | exciting? | 18:24 |
| lisitsyn | gsoc wise everything is ok - fernando and kevin are doing pretty well | 18:24 |
| lisitsyn | HeikoS: well I changed my 12 m2 to 58 m2 | 18:24 |
| lisitsyn | ;) | 18:24 |
| @HeikoS | I see | 18:25 |
| @HeikoS | like I change my e2 7dj to e2 7ja recently :)( | 18:25 |
| lisitsyn | HeikoS: ehmhmm | 18:25 |
| lisitsyn | :D | 18:25 |
| lisitsyn | what? | 18:25 |
| lisitsyn | HeikoS: m2 = m^2 | 18:26 |
| @HeikoS | ah | 18:26 |
| lisitsyn | like sq.m. | 18:26 |
| @HeikoS | haha :) | 18:26 |
| lisitsyn | hahah | 18:26 |
| @HeikoS | wow thats nice then | 18:26 |
| lisitsyn | I get your joke haha | 18:26 |
| @HeikoS | I though that was a postcode | 18:26 |
| lisitsyn | ahh | 18:26 |
| lisitsyn | it wasn't | 18:26 |
| lisitsyn | :D | 18:26 |
| lisitsyn | I thought you said some non-sense like I did | 18:26 |
| lisitsyn | HeikoS: yeah that's area | 18:26 |
| lisitsyn | HeikoS: what about you? | 18:28 |
| lisitsyn | ohohoh | 18:28 |
| lisitsyn | what's with doc sprint | 18:28 |
| @HeikoS | ? | 18:28 |
| lisitsyn | I think we're missing it | 18:28 |
| @HeikoS | lisitsyn: we could apply | 18:28 |
| @HeikoS | deadline is 6th | 18:28 |
| lisitsyn | do we have real idea? | 18:28 |
| @HeikoS | I am not really sure though | 18:28 |
| lisitsyn | HeikoS: carol didn't contact me too | 18:29 |
| @HeikoS | we are missing a clear goal with that | 18:29 |
| lisitsyn | about gsoc meeting | 18:29 |
| @HeikoS | contact? | 18:29 |
| lisitsyn | well I am on the waiting list | 18:29 |
| @HeikoS | ah we still need to get the PO number | 18:29 |
| @HeikoS | ah man | 18:29 |
| @HeikoS | so annoying with my bank | 18:29 |
| lisitsyn | what's with your bank? | 18:29 |
| @HeikoS | I dont have an account on my name | 18:29 |
| @HeikoS | or I do have but I dont know the number | 18:29 |
| lisitsyn | hmm | 18:30 |
| @HeikoS | and my parents are in vaccation | 18:30 |
| lisitsyn | what kind of account? | 18:30 |
| @HeikoS | post lying at their place | 18:30 |
| @HeikoS | for GSoC money | 18:30 |
| lisitsyn | but you do have some mastercard or visa or anything? | 18:30 |
| @HeikoS | I will call them tomorow again | 18:30 |
| @HeikoS | not in Germany | 18:30 |
| lisitsyn | ahh | 18:30 |
| @HeikoS | in England I would have to pay taxes | 18:30 |
| lisitsyn | complicated | 18:30 |
| @HeikoS | yeah annoying | 18:31 |
| @HeikoS | lisitsyn: I will get some food now, be back in 15 mins | 18:31 |
| lisitsyn | HeikoS: I think I'll ask carol if I have any chances | 18:31 |
| lisitsyn | ok see you then ;) | 18:31 |
| @HeikoS | lisitsyn: ask sonney, I think we get a fixed amount | 18:31 |
| @HeikoS | so we should book flights asap | 18:31 |
| @HeikoS | so I need to sort out bank stuff asap | 18:32 |
| @HeikoS | ill be back soon, catch up then | 18:32 |
| lisitsyn | HeikoS: hmm but that's the flight | 18:32 |
| lisitsyn | we need a hotel reservation for me etc | 18:32 |

| @HeikoS | re | 18:54 |
| @HeikoS | iglesiasg: any updates on that freeze you had? | 19:12 |
| @iglesiasg | HeikoS, no, not yet sorry. I am doing the unit test sonney2k ask for this issue https://gist.github.com/iglesias/6145782 | 19:12 |
| @iglesiasg | HeikoS, I won't be able to take a further look at it until tomorrow | 19:13 |
| @iglesiasg | HeikoS, Tuesday morning latest | 19:13 |
| @HeikoS | iglesiasg: ah I see, unit test is good :) | 19:13 |
| @iglesiasg | but I won't forget about it! I leave your mail as not read :) | 19:13 |
| @HeikoS | iglesiasg: cool thanks :) | 19:16 |
| @HeikoS | iglesiasg: no rush on this btw | 19:16 |
| @HeikoS | as long as travis and the buildbot dont complain | 19:16 |
| @iglesiasg | HeikoS, sure | 19:16 |
| @iglesiasg | HeikoS, although the travis build for that PR was a bit weird, wasn't it? Lot of grey in there | 19:17 |
| @HeikoS | iglesiasg: yeah it was | 19:17 |
| @HeikoS | I thought it ran out of time (it does sometimes= | 19:17 |
| @HeikoS | so I merged since the previous compile error were gone | 19:17 |
| @iglesiasg | aham I see | 19:18 |
| @iglesiasg | HeikoS, I was thinking for the multi-threaded cross-validation issue | 19:33 |
| @HeikoS | iglesiasg: yes? | 19:34 |
| @iglesiasg | what if the subset is not in shared memory, so you have several process running with its own subset | 19:34 |
| @iglesiasg | then I think it would not be necessary to have multiple subsets | 19:34 |
| @HeikoS | iglesiasg: yeah thats the goal | 19:35 |
| @HeikoS | iglesiasg: but the labels should stay shared | 19:35 |
| @HeikoS | or labels dont matter | 19:35 |
| @HeikoS | features should be shared | 19:35 |
| @iglesiasg | HeikoS, indeed | 19:35 |
| @HeikoS | so they need multiple subsets | 19:35 |
| @HeikoS | since all threads work on the same feature object | 19:35 |
| @iglesiasg | mmm | 19:35 |
| @iglesiasg | I was thinking if there is a way to have the features shared but not the subset | 19:36 |
| @iglesiasg | but that would break with how it is currently done | 19:36 |
| @iglesiasg | since the subset is a member of the features IIRC | 19:36 |
| @HeikoS | iglesiasg: where is the difference? | 19:36 |
| @HeikoS | iglesiasg: when features store multiple subsets and 1 object is shared | 19:37 |
| @HeikoS | or if implementations store their own subset? | 19:37 |
| @HeikoS | I think they also should be kept within the features to avoid problems | 19:37 |
| @iglesiasg | HeikoS, I have the idea that it could be different. If cross-validation is run by different processes, then each process has its own subset in its own memory space | 19:38 |
| @iglesiasg | but in the code there is only one subset, no multiple ones | 19:38 |
| @HeikoS | iglesiasg: yes, but where is the difference or advantage to store the subset on the shared feature object? | 19:38 |
| @iglesiasg | HeikoS, I think it should be easier to program if there is only one subset to take into account | 19:39 |
| @HeikoS | iglesiasg: there is, you just have to pass/remember the id | 19:39 |
| @HeikoS | the only difference is where it is stored | 19:39 |
| @iglesiasg | HeikoS, I didn't understand that, sorry | 19:40 |
| @HeikoS | iglesiasg: only difference is where the subset is stored | 19:41 |
| @iglesiasg | HeikoS, yes | 19:42 |
| @iglesiasg | in any case I think my idea is not correct | 19:43 |
| @HeikoS | why nor? | 19:43 |
| @HeikoS | not? | 19:43 |
| @iglesiasg | I don't think it is possible to have several processes that share part of the memory (the features) and not other part (the subsets) | 19:43 |

| lambday | HeikoS: should we try seeing the performance of cg_m instead of individual cg? I think this would be the bottleneck! | 20:04 |
| lambday | cg solvers are not trustworthy :( | 20:04 |
| lambday | HeikoS: another thing, the only thing that changes in "LogRationalApproximationIndividual::submit_jobs" is the part which creates new operators for dense and sparse matrices... I don't want to write just another class for sparse... so I can check for types dynamically I think! | 20:08 |
