| @sonney2k | lambday_, it says possibly lost - so relax | 00:39 |
|---|---|---|
| * sonney2k yay easter holdays | 00:40 | |
| lambday_ | sonney2k: yeah... its kind of annoying though | 00:40 |
| lambday_ | sonney2k: long time no see! :D | 00:40 |
| @sonney2k | yeah busy... | 00:40 |
| @lisitsyn | sonney2k: oh who's there | 00:41 |
| @sonney2k | lambday_, well I mean it is harmless if libraries at startup allocate some buffers that they never free | 00:41 |
| @sonney2k | I mean it can only be freed once done using the lib which usually is only on program exit | 00:42 |
| @sonney2k | lisitsyn, heh | 00:42 |
| lambday_ | sonney2k: yeah I was stuck at it for a while until lisitsyn explained it to me.. | 00:42 |
| @lisitsyn | sonney2k: have you seen my fancy blog?! | 00:42 |
| @lisitsyn | :D | 00:42 |
| @sonney2k | lisitsyn, YOU HAVE A BLOG? | 00:43 |
| @sonney2k | lisitsyn, kidding? | 00:43 |
| lambday_ | sonney2k: it does mean a thing :D | 00:43 |
| @lisitsyn | sonney2k: now yes | 00:43 |
| @sonney2k | lisitsyn, are you on shogun planet just yet? | 00:43 |
| @lisitsyn | sonney2k: no I don't think so | 00:43 |
| @sonney2k | lisitsyn, well then give me the url and I put you live :D | 00:43 |
| @lisitsyn | I forgot about this thing | 00:43 |
| @lisitsyn | sonney2k: http://sergey.lisitsyn.me | 00:44 |
| @sonney2k | lisitsyn, I need the rss | 00:44 |
| @lisitsyn | sonney2k: I am not sure I set it up | 00:44 |
| @lisitsyn | sonney2k: is atom.xml the right thing? | 00:44 |
| @lisitsyn | if it doesn't work I can set up rss as well I guess | 00:45 |
| @sonney2k | http://sergey.lisitsyn.me/atom.xml right? | 00:45 |
| @lisitsyn | sonney2k: correct | 00:45 |
| @sonney2k | man I am brainwashed | 00:45 |
| @sonney2k | all shogun related knowledges swapped out | 00:46 |
| @lisitsyn | hmm I have no idea what's with rss in octopress | 00:46 |
| * sonney2k is trying to find some backup tapes | 00:46 | |
| @lisitsyn | sonney2k: knowledges like? | 00:46 |
| @sonney2k | lisitsyn, anything | 00:46 |
| @lisitsyn | sonney2k: hmm is std::vector contiguous? | 00:46 |
| lambday_ | lol | 00:46 |
| @sonney2k | lisitsyn, accoring to latest standards it is hurray! | 00:47 |
| @lisitsyn | sonney2k: starting from C98 | 00:47 |
| @lisitsyn | :D | 00:47 |
| @lisitsyn | it was latest when you were young ;) | 00:47 |
| @lisitsyn | btw in C++14 | 00:47 |
| @lisitsyn | you can finally do | 00:47 |
| @lisitsyn | [] (auto x) { ... } | 00:47 |
| @lisitsyn | generic lambdas! | 00:47 |
| lambday_ | I heard lambda | 00:48 |
| @lisitsyn | lambday_: what does [&] in lambda mean? ;) | 00:48 |
| @lisitsyn | <interview mode> | 00:48 |
| lambday_ | lisitsyn: take by ref | 00:49 |
| lambday_ | ? | 00:49 |
| @lisitsyn | take what by ref? | 00:49 |
| lambday_ | whatever you pass :-/ | 00:49 |
| lambday_ | from env | 00:49 |
| @sonney2k | lisitsyn, there we go http://shogun-toolbox.org/page/planet/shogun | 00:49 |
| @lisitsyn | lambday_: env? ;) what is env? | 00:50 |
| @lisitsyn | sonney2k: ha cool thanks | 00:50 |
| lambday_ | any var that | 00:50 |
| lambday_ | s's defined in that scope? | 00:50 |
| lambday_ | :P | 00:50 |
| @lisitsyn | lambday_: yeah scope is correct ;) | 00:50 |
| @lisitsyn | lambday_: what is [=]? | 00:50 |
| lambday_ | forgot :D | 00:50 |
| * lambday_ quick googles | 00:51 | |
| @sonney2k | lisitsyn, will you attend the dedup meeting? | 00:51 |
| @lisitsyn | sonney2k: yeah | 00:51 |
| @sonney2k | excellent | 00:51 |
| lambday_ | lisitsyn: found :D | 00:51 |
| @lisitsyn | lambday_: by value, right? ;) | 00:53 |
| lambday_ | lisitsyn: yo! | 00:53 |
| @lisitsyn | sonney2k: if I get hit by bus | 00:53 |
| @lisitsyn | heiko will take care | 00:53 |

| @sonney2k | lisitsyn, or you don't find the way around the fance ;) | 00:57 |
| @lisitsyn | sonney2k: hah you have enjoyed this video it seems | 00:57 |
| @lisitsyn | lambday_: http://www.youtube.com/watch?v=1IAXrxlDK6c | 00:58 |
| @sonney2k | lisitsyn, pretty obvious isn't it? | 00:59 |
| @lisitsyn | sonney2k: that's funny cause I don't really get it :D | 00:59 |
| @lisitsyn | it seems if you live here that's ok | 00:59 |
| @lisitsyn | sonney2k: have you heard mahout is moving to spark? | 01:00 |
| @sonney2k | lisitsyn, yes seen that | 01:01 |
| @sonney2k | map reduce is close to useless for ML | 01:01 |
| @sonney2k | it has always been | 01:01 |
| @sonney2k | it is googles way of computing very simple statistics | 01:01 |
| @sonney2k | which is sufficient if you have massive data in *many* cases | 01:01 |
| @lisitsyn | sonney2k: I still think we should find a way into distributed things | 01:02 |

| @sonney2k | lisitsyn2, well do it :) I don't have big enough data for that :D | 01:08 |
| @sonney2k | so for me personally what we have is sufficient | 01:08 |
| lisitsyn2 | sonney2k: yeah that is apparently the main thing | 01:09 |
| @sonney2k | so it somebody who has too much data should take care of that | 01:09 |
| lisitsyn2 | if we want to be distributed | 01:09 |
| lisitsyn2 | we need to have a few machines | 01:09 |
| lisitsyn2 | I don't really have a cluster :D | 01:09 |
| @sonney2k | well none of us used the google grant right | 01:10 |
| @sonney2k | no idea really how we could get this to work other than bying a couple of el-cheapo machines | 01:10 |
| lisitsyn2 | sonney2k: is this grant lost? | 01:11 |
| @sonney2k | lisitsyn2, it times out after 6 months | 01:11 |
| lisitsyn2 | sucks | 01:11 |
| @sonney2k | lisitsyn2, you know I have a cellar | 01:11 |
| @sonney2k | so maybe 5 cheap nodes should be doable | 01:11 |
| lisitsyn2 | want to pay electricity bills? ;) | 01:12 |
| lisitsyn2 | sonney2k: isn't it not el cheapo? | 01:12 |
| @sonney2k | no shogun foundation has to as well as for the machines if we want that. maybe each 32G or so | 01:12 |
| @sonney2k | but electricity is not the main thing if the machines idle | 01:12 |
| @sonney2k | lisitsyn2, alternative is we rent a couple of machines | 01:13 |

| lisitsyn | battery effectively died :D | 01:17 |

| lambday_ | lisitsyn1: return type of a public method of CKernel | 11:52 |
| lambday_ | SWIG supports std::pair | 11:52 |
| lambday_ | but may be gotta att template() std_pair<SGVector<float64_t>,SGVector<float64_t> > in modshogun.i for that to work? | 11:53 |

| lisitsyn1 | lambday_: oh well I'd avoid it :D | 11:54 |
| lisitsyn1 | think how it would look like in python, java and say octave | 11:54 |
| lambday_ | lisitsyn1: well, in python a tuple of numpy vectors :D | 11:55 |
| lambday_ | lisitsyn1: so what do you suggest? | 11:56 |
| lisitsyn1 | lambday_: no clue yet, let me think | 11:56 |
| lambday_ | SGMatrix is waste of memory since their size differs | 11:56 |
| lambday_ | CList is overkill | 11:56 |
| lambday_ | may be just concatenated vectors | 11:57 |
| lisitsyn1 | lambday_: what are these vectors? | 11:57 |
| lambday_ | first n entries belong to vector a and m entries belong to vector b | 11:57 |
| lambday_ | lisitsyn1: vec1 = row-wise sum of kernel values | 11:57 |
| lambday_ | vec2 = col-wise -do- | 11:58 |
| lambday_ | (when its not symmetric) | 11:58 |
| lisitsyn1 | ahh | 11:58 |
| lambday_ | I don't want to call CKernel::kernel(i, j) more than once per (i,j) so I need to return both of these in one method | 11:59 |
| lisitsyn1 | lambday_: what about some precomputing on call | 11:59 |
| lisitsyn1 | and two methods? | 11:59 |
| lambday_ | lisitsyn1: if I can precompute the whole kernel matrix then we won't be needing these methods | 11:59 |
| lisitsyn1 | no I mean | 11:59 |
| lisitsyn1 | if you want col sums | 11:59 |
| lisitsyn1 | you precompute col/row sums | 11:59 |
| lisitsyn1 | and return col sums | 12:00 |
| lambday_ | storing things between calls? | 12:00 |
| lisitsyn1 | ??? | 12:00 |
| lisitsyn1 | yes | 12:00 |
| lisitsyn1 | :D sorry | 12:00 |
| lambday_ | ?? ??? ????? | 12:00 |
| lambday_ | :? | 12:00 |
| lisitsyn1 | hahaha | 12:00 |
| lambday_ | umm... lisitsyn1 I don't like storing :( | 12:01 |
| lisitsyn1 | lambday_: possible bugs | 12:01 |
| lambday_ | concatenation can do - the callee always know the num-rows and num-cols... so a vec of num-rows+num_cols element can do I guess .... first vec[0:num_rows] are row-wise sums and rest are col-wise sums | 12:03 |
| lisitsyn1 | lambday_: why clist is overkill? | 12:03 |
| lisitsyn1 | lambday_: concatenation looks like a workaround for me | 12:04 |
| lambday_ | lisitsyn1: because its just 2 elements... we can do better than a linked list | 12:04 |
| lisitsyn1 | lambday_: is it expected to be used often? | 12:04 |
| lambday_ | lisitsyn1: fairly | 12:04 |
| lisitsyn1 | lambday_: hmm.. | 12:05 |

| lambday_ | HeikoS: please have a look when you're free :) | 19:19 |
| @HeikoS | nice | 19:19 |
| @HeikoS | will have a look pretty much now | 19:19 |
| lambday_ | :D | 19:19 |
| lambday_ | made openmp-ed as well | 19:20 |
| lambday_ | will add overridden sum methods for CustomKernel in the next patch | 19:21 |
| lisitsyn | HeikoS: yeah here | 19:36 |
| lisitsyn | HeikoS: well meeting is in a hour | 19:37 |
| lisitsyn | :) | 19:37 |
| @HeikoS | lambday_: very nice work! | 19:42 |
| @HeikoS | lambday_: this also will make the MMD stuff on custom kernels a lot faster | 19:42 |
| @HeikoS | as we dont loop over these virtual method calls anymore | 19:42 |
| lambday_ | HeikoS: I hope so.. | 19:43 |
| lambday_ | HeikoS: will add CustomKernel stuffs soon.. | 19:44 |
| lambday_ | HeikoS: I think I need to reduce the accuracy a bit.. will update the PR in a sec | 19:44 |

| lambday_ | when ran with ctest it all went through but with valgrind one test is complaining to be 1E-14 | 19:44 |
| @HeikoS | ok | 19:45 |
| @HeikoS | yeah e-14 is ok :) | 19:45 |
| @HeikoS | lambday_: I would actually be interested in a performance coparison | 19:46 |
| @HeikoS | lambday_: are you interested in coding one up and put into benchmarks? | 19:46 |
| @HeikoS | lambday_: google doesnt really answer this | 19:47 |
| @HeikoS | lambday_: all probably depends on compiler optimisations | 19:47 |
| lambday_ | HeikoS: with previous implementation and with replaced by these calls? | 19:47 |
| @HeikoS | lambday_: not for MMD but kernel in general | 19:47 |
| @HeikoS | one that loops over the ::kernel calls | 19:47 |
| @HeikoS | and one that calls your method | 19:47 |
| @HeikoS | for Custom kernel | 19:47 |
| @HeikoS | for GaussianKernel or others it should be the same since the kernel call has to be done | 19:48 |
| @HeikoS | ::kenrel call I mean | 19:48 |
| @HeikoS | ah wait | 19:48 |
| lambday_ | HeikoS: I am interested in setting up these benchmarks.. | 19:57 |
| lambday_ | HeikoS: will try to do it by tonight | 19:57 |
| lambday_ | HeikoS: I will just be back after dinner :) | 19:57 |
