| @sonney2k | wiking, hey there! | 11:16 |
| @sonney2k | foulwall`, neat! so the whole machinery beneath is already working? | 11:18 |
| @wiking | sonney2k: can we fix buildbot nightly? :) | 11:18 |
| @sonney2k | foulwall`, just the centering / extracting the region is missing and I guess you should also load the model just once for this demo if it takes too long | 11:19 |
| @sonney2k | wiking, what's wrong with it? | 11:19 |
| @wiking | sonney2k: i mean to generate the .tar.gz of the binaries? | 11:19 |
| -!- van51 [~van51@athedsl-399972.home.otenet.gr] has joined #shogun | 11:19 | |
| @sonney2k | wiking, we just need a make target for that and then we can do it | 11:20 |
| @wiking | ok | 11:20 |
| @sonney2k | wiking, did sergey come to the 3nd workshop day btw? | 11:20 |
| @wiking | btw are we doing this for the r_modular: PKG_LIBS="example.cxx" R CMD SHLIB -o example example_wrap.cpp | 11:20 |
| @wiking | " R is also sensitive to the name of the file extension in C and C++ mode. In C++ mode, the file extension must be .cpp rather than .cxx for the R compile command to recognize it. If your C++ code is in a file using something other than a .cpp extension, then it may still work using PKG_LIBS: | 11:20 |
| @wiking | swig" | 11:20 |
| @sonney2k | wiking, no we are doing something totally custom | 11:21 |
| @wiking | sonney2k: oh i see | 11:21 |
| @sonney2k | wiking, I did a bit of R debugging in the last days | 11:22 |
| @sonney2k | wiking, at least my minimal example worked with ref/unref jsut fine | 11:22 |
| @sonney2k | wiking, now I am trying to get a minimal shogun class to work | 11:22 |
| @sonney2k | say BinaryLables | 11:22 |
| @sonney2k | *Labels | 11:23 |
| @sonney2k | if this works then it is just some shogun thing | 11:23 |
| @sonney2k | but it is complex... | 11:23 |
| foulwall` | ok, sonney2k, gotcha, will send a pr soon. | 11:35 |

| @sonney2k | wiking, did you have the chance to check the videos of the workshop? | 11:48 |
| lambday | sonney2k: hi | 11:51 |
| @sonney2k | lambday, hey there! | 11:53 |
| lambday | sonney2k: I need to add a different dense_dot in SGSparseVector, something that takes another template argument... say, when I need to compute sparse-matrix-vector product when matrix is complex64 and vector is float64 | 11:54 |
| lambday | sonney2k: would that be okay? | 11:55 |
| @sonney2k | lambday, it makes sense to have these | 12:02 |
| lambday | sonney2k: okay... so adding a few of them, complex64, float64, int etc.... | 12:02 |
| @sonney2k | lambday, I wanted to have this in CDotFeatures but IIRC deriving from a templated class can be problem | 12:03 |
| @sonney2k | a | 12:03 |
| thoralf | sonney2k: I thought you'll in holiday now? | 12:05 |
| thoralf | you're | 12:05 |
| lambday | sonney2k: umm.. problem as in? | 12:05 |

| -!- mode/#shogun [+o iglesiasg] by ChanServ | 12:09 | |
| thoralf | Hey iglesiasg | 12:09 |
| @iglesiasg | good morning! | 12:09 |
| van51 | hey | 12:10 |
| van51 | sonney2k: I've sent a PR, when you have time please review it :) | 12:10 |
| van51 | sonney2k: I've started working on the streaming version of those | 12:10 |
| van51 | sonney2k: if you want to discuss anything I'll be around | 12:11 |
| van51 | lambday: I think it will be a bit messier to extend a templated class | 12:11 |
| @iglesiasg | thoralf: I will fix the SO multiclass example ASAP (I want to finish an LMNN thing first). But if you want to do it, feel free ;) | 12:11 |
| van51 | lambday: I tried it two-three days ago with DenseFeatures (which are templated) | 12:11 |
| thoralf | iglesiasg: No worries. | 12:11 |
| van51 | lambday: ofc I'm not a c++ expert (yet :P) so that may be we it troubled me | 12:11 |
| van51 | why* | 12:12 |
| lambday | van51: yes templates are real pain :( | 12:12 |
| lambday | van51: well I am thinking of having something like this | 12:12 |
| thoralf | iglesiasg: I need multilabel instead of multiclass. So I anyway will write my own example/classes. | 12:12 |
| lambday | template<class T1> class { template<class T2> void foo(T2 a); }; | 12:13 |
| van51 | lambday: yea I saw what you wanted to do, with the sparse product | 12:14 |
| lambday | oops I forgot the class name itself :D | 12:14 |
| @iglesiasg | thoralf: Aham, I understand. | 12:14 |
| lambday | van51: yes | 12:14 |
| van51 | lambday: i think it will be really useful :) | 12:14 |
| lambday | van51: I hope so.. I will be using those anyway | 12:14 |
| thoralf | iglesiasg: I spend a night reading your SO stuff and I think I need some modifications for multilabel. | 12:15 |
| lambday | by the way, how did the workshop go, guys? | 12:15 |
| lambday | saw the pics :) | 12:15 |
| -!- nube [~rho@116.90.239.13] has quit [Quit: Leaving.] | 12:16 | |
| van51 | and what about the videos? :D | 12:16 |
| @iglesiasg | thoralf: So, first of all you need a new model, right? In multilabel you want to model dependencies between all pairs of classes, or not? | 12:16 |
| lambday | yes yes what about the video :D | 12:16 |
| @iglesiasg | all pairs of labels, better said probably | 12:16 |
| lambday | umm... make unit-tests now treats all warnings as errors :-/ | 12:17 |
| @iglesiasg | lambday: the workshop was pretty cool | 12:18 |
| @iglesiasg | lambday: I enjoyed a lot the days in there. We had a couple of coding days during the weekend | 12:18 |
| lambday | iglesiasg: awesome, man!! | 12:18 |
| @iglesiasg | van51: I think wiking or sonney2k are editing them and later they will be uploaded to youtube | 12:19 |
| van51 | iglesiasg: ok cool! thanks for letting me know | 12:19 |
| @iglesiasg | lambday, van51: did you guys follow the live stream? | 12:20 |
| lambday | iglesiasg: no I couldn't :( | 12:20 |
| lambday | iglesiasg: will the slides be available? | 12:20 |
| @iglesiasg | lambday: I thought they already were | 12:26 |
| @iglesiasg | lambday: have you checked the logs? I think there were some links to them pasted here | 12:26 |
| @iglesiasg | lambday: anyway, yes. I think they will be uploaded somewhere in the website once the videos are up and so on. | 12:27 |
| lambday | iglesiasg: alright.. thanks.. I'll check it out :) | 12:32 |
| thoralf | iglesiasg: No, only between some classes. | 12:54 |
| thoralf | iglesiasg: It's a taxonomy. | 12:54 |
| thoralf | iglesiasg: I don't even need to learn label-label interactions. | 12:55 |
| @iglesiasg | thoralf: Aham! Got it. | 12:58 |
| @iglesiasg | thoralf: So you could as well use directly multiclass classification too. Each class corresponding to a particular choice of the labels. | 12:59 |
| thoralf | iglesiasg: How do I model that a class belongs to class i and class j? | 13:00 |
| thoralf | iglesiasg: btw.: I have 7000 labels - so "label combinations" won't work. ;) | 13:01 |
| @iglesiasg | thoralf: yeah, indeed that's way too many classes for doing that | 13:02 |
| @iglesiasg | thoralf: so if I understand correctly, for your labels you can probably use the Sequence labels, and for the features probably MatrixFeatures work well. What needs to be new is the StructuredModel | 13:04 |

| thoralf | iglesiasg: No, travis wasn't triggered. | 14:57 |
| thoralf | I don't know why. | 14:57 |
| @iglesiasg | thoralf: but the PR cannot be merged from the github's interface | 14:58 |
| @iglesiasg | thoralf: "We can't automatically merge this pull request. Use the command line to resolve conflicts before continuing." | 14:58 |
| thoralf | iglesiasg: That's weird. | 14:59 |
| thoralf | I'll have a look. | 14:59 |
| @iglesiasg | thoralf: I have not seen it before either. I would try to rebase to latest develop and see if I get any conflict | 14:59 |
| thoralf | iglesiasg: Okay, I did a rebase and pushed it again (there was indeed a conflicting change) - let's hope github is able to merge it. | 15:07 |
| thoralf | iglesiasg: Travis runs, a good sign. | 15:07 |
| @iglesiasg | thoralf: good | 15:11 |
| @iglesiasg | thoralf: I am no real Makefile expert though, so I am probably not the right one to merge this. Do you need to get this merged soon? | 15:13 |
| thoralf | iglesiasg: I guess this happened because HeikoS PR got merged before mine - and introduced a conflict, which wasn't there before. ;) | 15:13 |
| @iglesiasg | probably | 15:13 |
| thoralf | iglesiasg: Not really, but later merges mean more potential conflicts. ;) | 15:13 |
| thoralf | iglesiasg: I can explain my changes - would that help? | 15:14 |
| @iglesiasg | thoralf: I understand what's going on. But I don't know if it can potentially arise conflict with sometihng | 15:18 |

| @HeikoS | lisitsyn: hey! | 19:54 |
| lisitsyn | HeikoS: hey | 19:54 |
| @HeikoS | lisitsyn: where are you? :) | 19:54 |
| lisitsyn | HeikoS: just got back home | 19:54 |
| lisitsyn | I am like pheew | 19:54 |
| @HeikoS | lisitsyn: good trip? | 19:54 |
| lisitsyn | HeikoS: the issue is that I feel a bit pheeew about russia now | 19:55 |
| @HeikoS | lisitsyn: ah, Berlin got you? :D | 19:55 |
| lisitsyn | HeikoS: yes totally | 19:55 |
| @HeikoS | lisitsyn: many Russians here, you should come ;) | 19:55 |
| pickle27 | from what i' | 19:55 |
| lisitsyn | HeikoS: I am afraid I could do that one day | 19:55 |
| @HeikoS | still enjoying the city, will depart tomorrow | 19:55 |
| lisitsyn | HeikoS: have you been to einstein stammhaus? | 19:56 |
| pickle27 | sorry from what I've heard Berlin would make a lot of places seem pheew | 19:56 |
| @HeikoS | lisitsyn: not yet | 19:56 |
| @HeikoS | pickle27: yeh its kinda nice here | 19:56 |
| lisitsyn | HeikoS: you should try their apfelstrudel and espresso I think! | 19:56 |
| @HeikoS | the only thing is: if you are here, you tend to not work but do other nice things ;) | 19:56 |
| @HeikoS | lisitsyn: haha :) apfelstrudel and espresso! :) | 19:56 |
| lisitsyn | not really cheap (these two ones would cost like around 10EUR) | 19:57 |
| lisitsyn | pickle27: well as I have not been to any foreign country before | 19:57 |
| pickle27 | ah | 19:58 |
| lisitsyn | ;) | 19:58 |
| @HeikoS | lisitsyn: really glad you liked it! :) | 19:58 |
| pickle27 | travelling is fun! | 19:58 |
| lisitsyn | pickle27: well I started to earn some enough money so I get it now ;) | 19:59 |
| @HeikoS | lambday: something is weird in the Parameter::add things for example | 19:59 |
| @HeikoS | Parameter::add_matrix(SGSparseVector<int32_t>** param, | 19:59 |
| @HeikoS | index_t* length_y, index_t* length_x, | 19:59 |
| @HeikoS | const char* name, const char* description) { | 19:59 |
| @HeikoS | TSGDataType type(CT_MATRIX, ST_SPARSE, PT_INT32, length_y, | 19:59 |
| lisitsyn | HeikoS: I should be back and check some other cities too! | 19:59 |
| pickle27 | awesome! | 19:59 |
| @sonney2k | lisitsyn, what did you do on sunday? | 19:59 |
| @HeikoS | lisitsyn: you should, Berlin is among the nicest though! | 19:59 |
| lisitsyn | sonney2k: hauptbahnhof shopping :D | 19:59 |
| @sonney2k | pfff | 19:59 |
| lisitsyn | well at least I have found something for my mother (she has birthday in a few days) | 20:00 |
| lisitsyn | HeikoS: oh man I want to get back already | 20:00 |
| lambday | HeikoS: add matrix? | 20:00 |
| lambday | HeikoS: I didn't add that | 20:01 |
| @HeikoS | lambday: ah I see | 20:01 |
| lambday | oh | 20:01 |
| lambday | nono | 20:01 |
| @HeikoS | lambday: even so, is that correct, see email | 20:01 |
| @HeikoS | lisitsyn: hehe | 20:01 |
| @HeikoS | lisitsyn: you should come back, and next time hang out with us some more :) | 20:01 |
| gsomix | lisitsyn, hi! | 20:01 |
| lambday | HeikoS: checking | 20:02 |
| lambday | HeikoS: | 20:05 |
| @HeikoS | lambday: ah found some more bugs in clone :( | 20:05 |
| lambday | Parameter::add(SGSparseVector<complex64_t> has all CT_SCALARs | 20:05 |
| @HeikoS | lambday: I know | 20:05 |
| @HeikoS | sonney2k: how are sparse vectors represented | 20:06 |
| @HeikoS | CT_SCALAR ot CT_VECTOR? | 20:06 |
| lambday | I mean Parameter::add(SGSparseVector<T> has all CT_SCALARs | 20:06 |
| @HeikoS | currenlty confused | 20:06 |
| @sonney2k | HeikoS, scalars yes | 20:06 |
| @HeikoS | sonney how about sparse matrix? | 20:06 |
| @HeikoS | sonney2k: and when do we use CT_VECTOR with ST_SPARSE? | 20:07 |
| @sonney2k | HeikoS, dirk designed it that way | 20:07 |
| @HeikoS | sonney2k: its fine, just need to know, so CT_VECTOR is never used along with ST_SPARSE ? | 20:08 |
| @sonney2k | HeikoS, sparse matrix would be CT_SPARSE IMHO | 20:08 |
| @HeikoS | CT_SPARSE? | 20:08 |
| @HeikoS | we only have scalar, vector, matrix | 20:08 |
| @sonney2k | well we don't have that yet | 20:08 |
| @HeikoS | and ST_NONE and ST_SPARSE | 20:08 |
| @HeikoS | sonney2k: well yes there are combinations | 20:09 |
| @sonney2k | I am not up-to-date | 20:09 |
| @sonney2k | the idea was that one could have vectors/strings in a matrix | 20:09 |
| @HeikoS | sonney I see, makes sense | 20:09 |
| @HeikoS | sonney2k: but how about sparse vectors | 20:10 |
| @sonney2k | IMHO it makes things too complex | 20:10 |
| @HeikoS | so first thing is: sparse vectors of scalars | 20:10 |
| @sonney2k | we don't need that | 20:10 |
| @HeikoS | this would be CT_SCALAR and ST_SPARSE | 20:10 |
| @HeikoS | and then sparse matrices, how do we do that: in the code we have: ST_SPARSE and CT_MATRIX | 20:10 |
| @HeikoS | but thats weird | 20:10 |
| @HeikoS | not consistent | 20:10 |
| @sonney2k | HeikoS, well we don't have matrices of strings either | 20:12 |
| @HeikoS | sonney2k: no its all just scalar | 20:12 |
| @HeikoS | sonney2k: how do we represent sparse matrices of floats? | 20:12 |
| thoralf | HeikoS: Lists of sparse vectors ;) | 20:13 |
| @sonney2k | well I would be totally fine if we just had a container type scalar/vector/...sparse_matrix | 20:14 |
| @sonney2k | with some primitive type | 20:14 |
| @HeikoS | sonney2k: I dont want to change things, just understand | 20:14 |
| @sonney2k | and rather sgstring as container type | 20:14 |
| @sonney2k | I am saying that this is how I would have liked it to be | 20:15 |
| @HeikoS | sonney2k: ok I agree on that, but for now I want to fix that bug | 20:15 |
| @sonney2k | now we have for strings IIRC CT_VECTOR with ST_STRING | 20:15 |
| @HeikoS | and its related to sparse matrix things | 20:15 |
| @sonney2k | so that is why ST_SPARSE is the correct thing to do with this framework | 20:16 |
| @HeikoS | sonney2k: I am just wondering how to represent sparse matrices correct | 20:16 |
| @sonney2k | so you have a vector of sparse | 20:16 |
| @HeikoS | yes, thats CT_SCALAR and ST_SPARSE | 20:17 |
| @sonney2k | yeah | 20:17 |
| @HeikoS | and now I want sparse matrix, which seems to be CT_MATRIX and ST_SPARSE | 20:17 |
| thoralf | I like the scipy compressed sparse matrices. | 20:17 |
| @sonney2k | no and no | 20:17 |
| @sonney2k | shogun sparse vector === CT_SCALAR + ST_SPARSE | 20:18 |
| @HeikoS | sonney2k: I found this: | 20:18 |
| @sonney2k | shogun sparse matrix == CT_VECTOR + ST_SPARSE | 20:18 |
| @HeikoS | void Parameter::add(SGSparseMatrix<bool>* param, | 20:18 |
| @HeikoS | const char* name, const char* description) | 20:18 |
| @HeikoS | { | 20:18 |
| @HeikoS | TSGDataType type(CT_SGMATRIX, ST_SPARSE, PT_BOOL, ¶m->num_vectors, | 20:18 |
| @HeikoS | ¶m->num_features); | 20:18 |
| @HeikoS | add_type(&type, ¶m->sparse_matrix, name, description); | 20:18 |
| @HeikoS | } | 20:18 |
| @sonney2k | thoralf, heh they have 3 formats - so which one? | 20:19 |
| @HeikoS | whats that? | 20:19 |
| thoralf | sonney2k: compressed row/columns | 20:19 |
| @sonney2k | LIL, CSC, CRS | 20:19 |
| @HeikoS | sonney2k: I see, whats this code snippet doing the? | 20:19 |
| @sonney2k | thoralf, they are static though... | 20:19 |
| @HeikoS | there | 20:19 |
| @HeikoS | sonney2k: any ideas? | 20:19 |
| @sonney2k | thoralf, I mean no way to add a vector / insert | 20:20 |
| thoralf | sonney2k: Yeah, that's right. | 20:21 |
| @sonney2k | HeikoS, ohh I see an issue - with CT_VECTOR you cannot say how many dims the sparse matrix has | 20:21 |
| @HeikoS | sonney2k: so thats might be the reason why it is CT_MATRIX? | 20:22 |
| thoralf | sonney2k: Nobody wants to change sparse matrices... I always treat them as if they were read-only ;) | 20:22 |
| @HeikoS | sonney2k: that makes sense | 20:22 |
| thoralf | sonney2k: Btw: Appending vectors works well. | 20:22 |
| @sonney2k | thoralf, I mean for dense matrix types it totally makes sense to use just one big array (lapack & friends are optimized for that like hell) no idea if sparse libs have similiar optimiaztions | 20:22 |
| thoralf | sonney2k: At least for CSR | 20:22 |
| @sonney2k | HeikoS, yeah I guess but it is totally crap | 20:23 |
| @HeikoS | sonney2k: how would be the best way? | 20:23 |
| @HeikoS | just have container types only I guess: SCALAR, VECTOR, MATRIX, SPARSE_VECTOR, SPARSE_MATRIX? | 20:23 |
| @sonney2k | HeikoS, doing it with CT_SGSPARSEMATRIX | 20:23 |
| @HeikoS | and drop ST? | 20:24 |
| @sonney2k | and CT_SGSPARSEVECTOR | 20:24 |
| @sonney2k | yeah I would love to drop ST_* | 20:24 |
| @HeikoS | how to do strings then? | 20:24 |
| @HeikoS | vectors of chars? | 20:24 |
| @sonney2k | but I guess we can only drop it once strings are gone | 20:24 |
| thoralf | sonney2k: Hmm, I think sparse matrices are hard to optimize. I'm just thinking of dot products. | 20:25 |
| thoralf | sonney2k: So many conditions. I'd like to know how sparse a vector needs to be for that to pay. | 20:25 |
| @sonney2k | strings would be CT_SGSTRINGLIST | 20:25 |
| @HeikoS | I see, so no strings of matrices etc? | 20:25 |
| @sonney2k | thoralf, I guess people like the one doing gotblas would do that | 20:25 |
| @HeikoS | only SGObject | 20:25 |
| @HeikoS | sonney2k: man, this should have been done before clone/equals | 20:26 |
| thoralf | gotblas | 20:26 |
| thoralf | gotblas? | 20:26 |
| @sonney2k | HeikoS, I admittedly would prefer doing a new type for that when it happens | 20:26 |
| @HeikoS | soooo much refactoring now | 20:26 |
| @sonney2k | thoralf, gotoblas | 20:26 |
| thoralf | Oh, damn. Gotta got. See you! | 20:26 |
| @HeikoS | thoralf: bye! | 20:26 |
| @sonney2k | thoralf, cu!! | 20:26 |
| @HeikoS | sonney2k: parameter framework could be redone somehow then | 20:28 |
| @HeikoS | most classes dont interact that much | 20:28 |
| @sonney2k | I suspect it woudl be much easier this way | 20:29 |
| lambday | HeikoS: I'll be back later | 20:30 |
| lambday | see you | 20:30 |
| @HeikoS | sonney2k: mmh, so we would have to rewritte: adding/storing/registering and then load/save, and migrate(useless anyway in its current state) | 20:30 |
| @HeikoS | lambday: bye! | 20:30 |
| -!- lambday [67157e4f@gateway/web/freenode/ip.103.21.126.79] has quit [] | 20:30 | |
| @HeikoS | sonney2k: equals/clone once more | 20:31 |
| @sonney2k | HeikoS, sorry is it really that much? | 20:31 |
| @HeikoS | sonney2k: dont know | 20:31 |
| @HeikoS | trying to find out :) | 20:31 |
| @sonney2k | HeikoS, I mean ST_* exisits only for NONE and STRING | 20:31 |
| @sonney2k | so it cannot be | 20:31 |
| @sonney2k | I think just string needs to be done differently | 20:31 |
| @sonney2k | then all good | 20:31 |
| @HeikoS | sonney2k: save/load/migrate/equals/clone are all totally dependent on the structure CT/ST | 20:32 |
| @HeikoS | if we drop one, these basically have to be re-done | 20:32 |
| @HeikoS | and when we do this, we can also change the TSGDataType | 20:32 |
| @HeikoS | because its totally annoying | 20:32 |
| @HeikoS | and then we can also do things in a way that migration is easier | 20:32 |
| @sonney2k | sure just drop this parameter but then all the rest will still work | 20:32 |
| @HeikoS | (allocating paramters from scratch etc) | 20:32 |
| @HeikoS | sonney2k: dont know whether all that is feasible for someone doing other things .... | 20:33 |
| @HeikoS | might be a good GSoC project | 20:33 |
| @HeikoS | but ultra hard | 20:33 |
| @sonney2k | HeikoS, you are the expert with migration / modsel / parameters | 20:34 |
| @sonney2k | who would know if not you | 20:34 |
| @HeikoS | sonney2k: you :D | 20:34 |
| @sonney2k | but just removing SG_* seems very easy! | 20:34 |
| @sonney2k | ST_* | 20:34 |
| @HeikoS | sonney2k: ok, maybe thats a good start | 20:34 |
| @sonney2k | simply stuff later is a different problem | 20:35 |
| @HeikoS | sonney2k: what do you think about all those types that are blowing up Parameter.h? | 20:35 |
| @HeikoS | uint16_t? | 20:36 |
| @HeikoS | I never used that | 20:36 |
| @HeikoS | rather float64, float32, int32, int64, char | 20:36 |
| @HeikoS | not even unsigned | 20:36 |
| @HeikoS | sonney2k: oh on another thing: | 20:37 |
| @HeikoS | sonney2k: the spectrum kernel currently is done via those obtain_from_* method of string features | 20:37 |
| @HeikoS | which then generates this sparse representation of the k-mer counts | 20:37 |
| @HeikoS | and those are given to a kernel | 20:37 |
| @HeikoS | sonney2k: so no model-selection of k-mer length | 20:38 |
| @HeikoS | since one cannot do model-selection over features | 20:38 |
| @sonney2k | HeikoS, I am only using unsigned stuff like uint16_t / 32_t 64_t for strings | 20:38 |
| @sonney2k | HeikoS, I did some other spectrum features using all k=1...max_K | 20:39 |
| @sonney2k | with weights | 20:39 |
| @sonney2k | forgot what the name was | 20:40 |
| @sonney2k | but maybe it has the same problem | 20:40 |
| @HeikoS | sonney2k: can the kernel select the weights? | 20:40 |
| @sonney2k | don't remember | 20:40 |
| @HeikoS | ok | 20:40 |
| @sonney2k | IMHO it is not that much of a problem | 20:40 |
| @HeikoS | sonney2k: no problem, but no automated model selection | 20:41 |
| lisitsyn | pickle27: hey I just checked andreas mail | 20:41 |
| @HeikoS | sonney2k: btw model selection framework might be a bit useless anyway | 20:42 |
| pickle27 | lisitsyn: yeah I've been working on this today | 20:42 |
| @HeikoS | sonney2k: what counts more is cross-validation | 20:42 |
| @HeikoS | since grid-search is just a loop | 20:42 |
| pickle27 | lisitsyn: Im actually about to send an reply | 20:42 |
| @HeikoS | which users could easily set up themselved | 20:42 |
| @HeikoS | s | 20:42 |
| lisitsyn | pickle27: okay sure! | 20:42 |
| @HeikoS | sonney2k: but is very hard to maintain | 20:42 |
| @HeikoS | if we offer it | 20:42 |
| lisitsyn | pickle27: I am on vacations still so I'd try to do my best to get into algorithms and help with further planning | 20:43 |
| @HeikoS | sonney2k: at least for grid-search | 20:43 |
| @HeikoS | sonney2k: gradient based things are different | 20:43 |
| pickle27 | lisitsyn: yeah no prob, I have still got a bunch of things I want to get done before getting fully into example mode | 20:43 |
| lisitsyn | pickle27: is everything alright with your masters thesis? | 20:44 |
| pickle27 | lisitsyn: yeah I submitted and my defence is on Aug 1! | 20:44 |
| lisitsyn | oh I see | 20:44 |
| pickle27 | I meant shogun things to get done! | 20:44 |
| lisitsyn | what do you mean? by aug 1? | 20:45 |
| pickle27 | I mean there is a few more techniques I want to finish coding for shogun before I start putting all my attention to the final examples | 20:45 |
| pickle27 | Aug 1 is when I present my thesis | 20:46 |
| lisitsyn | ahh alright | 20:46 |

| @HeikoS | iglesiasg: yes, good to have the meeting soon | 21:02 |
| @HeikoS | sonney2k: nice :D | 21:02 |
| @iglesiasg | sonney2k: it sounds nice | 21:03 |
| @sonney2k | doing (late) nips reviews | 21:03 |
| @sonney2k | all rejects IMHO :/ | 21:03 |
| @iglesiasg | haha | 21:04 |
| @sonney2k | HeikoS, never get yourself's paper reviewed by me | 21:04 |
| @sonney2k | I don't remember accepting papers | 21:04 |
| @iglesiasg | we better hope for our papers not to be reviewed by you :P | 21:04 |

| @iglesiasg | sonney2k: btw, I was gladly surprised with Berlin. I found it an amazing place | 21:14 |
| @sonney2k | iglesiasg, yeah I like it too :) | 21:15 |
| @HeikoS | it is amazing :) I would find it hard to work here though - so many other nice things to do :) | 21:15 |
| @HeikoS | going now, see you! | 21:21 |
| @iglesiasg | HeikoS, sonney2k: BTW, could any of you take a quick look at thoralf PR when you get some time? | 21:22 |
| @HeikoS | iglesiasg: I did, I think its ok, but I dont know enough of makefiles t omerge it, sonney2k, wiking, or lisitsyn should have a look | 21:23 |

| @iglesiasg | we are in the same boat about Makefiles hehe | 21:23 |
| @iglesiasg | bye HeikoS | 21:24 |
| @sonney2k | iglesiasg, yeah had a look - not in mergeable state yet | 21:25 |
| @iglesiasg | sonney2k: because of the crash in travis build? | 21:26 |

| @iglesiasg | sonney2k: after Saturday's conversation I realized there is no need to make the methods static to avoid including LMNNImpl.h in LMNN.h, just need to do this forward declaration of the class CLMNNImpl. So I was thinking of doing that and make the methods non-static | 23:03 |
