@sonney2kjuly09:54
@sonney2kfoulwall`, you have to adjust the gp example a bit the syntax changed09:55

@sonney2klambday, I hope we can get some equipment for that12:12
@sonney2kvan51, did what I wrote make sense?12:16
van51sonney2k: yeap12:17
van51sonney2k: what I didn't quite get is for the nnz_features, why would the string length be better12:17
van51sonney2k: what I was/am thinking of doing there is to use the converter to transform the document to a SGSparseVector and store it and iterate it12:21
@sonney2kvan51, no the point is to do that on-the-fly12:25
@sonney2kvan51, and the nnz_features was IIRC just an estimation so an upper bound is fine12:25
van51sonney2k: but you can't iterate the features on the fly12:25
van51the nnz* features on the fly12:25
@sonney2kwhy not?12:25
van51you may get the same one again and again12:25
@sonney2kthat is ok12:26
van51and not in the correct order12:26
@sonney2kalso ok12:26
van51ok then :P12:26
van51these were my arguments12:26
@sonney2kjust think of it12:26
@sonney2kadd_to_dense_vec12:26
@sonney2kwill then just add the thing multiple times12:26
van51sonney2k: ah wait12:26
@sonney2kand dense_dot same thing12:26
van51sonney2k: I'm not talking about these methods12:26
@sonney2kignore the feature iterators12:26
van51sonney2k: but for the iterators12:27
@sonney2kjust do SG_NOT_IMPLEMENTED12:27
van51sonney2k: ok12:27
van51sonney2k: although we could iterate just the sparsevector there12:28
van51sonney2k: but I remember that the iterator is seldom used12:28
van51sonney2k: also, how important is the dot() method?12:29
van51sonney2k: should I also remove the converter from there?12:29
@sonney2kvan51, sufficient as is12:30
van51sonney2k: ok then12:30
van51sonney2k: I'll update the PR soon and start working on a unit test after that12:30
@sonney2kvan51, the iterator was intended for L1 methods12:31
@sonney2kvan51, yeah make a toy example give reasonable results and compare to the converter12:31
van51sonney2k: ok! I'll let you know how it goes12:32

van51sonney2k: I realize that reviewing so many PRs and stuff may be a bit too much work for you12:53
van51sonney2k: should I ask Olivier and Benoit to start reviewing my PRs, as well?12:53
van51sonney2k: and Quoc later on12:53

@sonney2kgsomix, hey there!20:19
gsomixsonney2k, hey.20:19
gsomixsonney2k, I'm here now 55.923552,37.52496220:21
@sonney2kgsomix, a village!20:27
@sonney2k... with internet!20:27
@sonney2kvan51, alright what is the status?20:28
gsomixsonney2k, not village, science city with MIPT. http://phystech.edu/20:28

van51sonney2k: it's going pretty good I think20:34
van51sonney2k: if you don't find something wrong with that's pushed already I just have to finish a unit test case20:35
van51sonney2k: and I'll get started on an example20:35
@sonney2kvan51, feedback send20:43
@sonney2kfix it and I can merge20:43
@sonney2kgsomix, alright so now you have time right?20:44
van51sonney2k: cool, thank you20:44
@sonney2kgsomix, if so then please finish of your first PR.. add tests! and use van51's *Tokenizer classes!20:44
gsomixsonney2k, yep. now  getting familiar with gmock and unit-tests.20:46
gsomixsonney2k, Tokenizer for what?20:47
@sonney2kgsomix, string splitting20:48
gsomixsonney2k, for LineReader and CircularBuffer? or for further readers?20:48
@sonney2kgsomix, for the ascii based readers it makes sense. also for .csv splitting etc20:52
gsomixsonney2k, ah, ok. it might be very useful. I will look into the van51's code.20:53
@sonney2kgsomix, alright so do the tests & get your PR ready then lets talk again :)21:00
gsomixsonney2k, ok21:01

pickle27hey guys22:30
pickle27I've got a weird bug that I haven't been able to get for a while22:30
pickle27I have an eigen map that isn't working and is causing a malloc memory corruption22:31
pickle27its wierd because I create an SGMatrix create a map on it, perform some math, all of which is fine22:31
pickle27then I pass the SGMatrix to a function and its the eigen map inside the func which fails22:32
pickle27the SGMatrix is fine though I just printed it22:32
pickle27iglesiasg: lisitsyn ^22:32
pickle27any ideas?22:33
lisitsynpickle27: hey22:33
lisitsyncan't say anything specific22:33
lisitsynlets see code ;)22:33
lisitsynwell actually22:34
lisitsynvalgrind detects such things - may be we can check its output too22:34
pickle27here is the code22:35
pickle27http://pastebin.com/yuzxDfHP22:35
pickle27um22:37
pickle27so when using valgrind it works ..22:37
pickle27something wierd is up because when I save the matrix to file it also worked22:37
lisitsynuhh22:38
lisitsynpickle27: may be remove references here22:38
lisitsynSGMatrix<float64_t> tdsep(SGMatrix<float64_t> &x, SGVector<float64_t> &sel)22:38
lisitsynyou don't get real advantage here but it may be unsafe22:39
lisitsynit shouldn't though22:39
pickle27okay22:39
pickle27I think I only added then to try and fix this22:39
pickle27with valgrind my the map prints but then the program stalls22:42
pickle27yeah this is weird, now that I can run this code (using valrind) I was able to debug the rest of it and now valgrind says no errors22:49
pickle27well nvm it says no leaks but there looks like some errors22:50
lisitsynpickle27: I see no reason to fail we need to force it to fail somehow22:50
lisitsynpickle27: it is not reference thing I am sure22:51
lisitsynpickle27: try to reproduce it under valgrind, its output could tell a lot22:52
pickle27found one thing22:53
pickle27lisitsyn: my SGVector was too small, silly mistake22:53
lisitsynohh yes22:53
lisitsyn4 vs 322:53
pickle27huh22:54
pickle27lisitsyn: that might have been it22:54
pickle27lisitsyn: strange how it manifested22:54
pickle27lisitsyn: cause yeah it runs now22:54
pickle27thanks! I never think to use valgrind but its pretty handy22:57
lisitsynpickle27: always use it when meet segfault  ;)22:58
