| sonne|work | foulwall: I think I will create a couple of reasonable datasets and put them in some repository - maybe even not shogun-data (slightly big already...) | 13:06 |
| foulwall | sonne|work: any suggests? | 13:06 |
| foulwall | sonne|work: Ok | 13:06 |
| sonne|work | foulwall: no just assume that you can load all *.h5 in some given dir and present them for loading | 13:07 |
| sonne|work | foulwall: maybe we even have a few data sets per category - e.g. some for binary classification, multiclass, regression | 13:08 |

| @lisitsyn | wiking: pong | 13:13 |
| @wiking | lisitsyn: openmp implementation...? :) | 13:13 |
| @wiking | lisitsyn: i can haz openmp with clang finally | 13:13 |
| lambday | HeikoS: hi | 13:14 |
| @HeikoS | lambday: hi! | 13:14 |
| @wiking | vgorbati: hey you've /msg -ed me about prng | 13:14 |
| @wiking | vgorbati: shoot what you need if you still need it | 13:14 |
| lambday | HeikoS: the initial class structure.. seems okay to you? | 13:14 |
| @HeikoS | lambday: yes | 13:14 |
| @HeikoS | so one thing I would maybe change: | 13:15 |
| @HeikoS | sampler as a base class | 13:15 |
| lambday | HeikoS: hmm... | 13:15 |
| @lisitsyn | wiking: openmp of? | 13:15 |
| @HeikoS | actually I would do this everywhere where there might be different implementations of things | 13:15 |
| lambday | okay.. not the enum there... | 13:15 |
| @HeikoS | then you call abstract methods and impleent them in subclasses | 13:15 |
| @HeikoS | only enum if you definitely know there are just a small number of cases and not more | 13:16 |
| @wiking | lisitsyn: i'm writing now bagging machien and it would be nice that i could do the training of the n machines in parallel | 13:16 |
| vgorbati | wiking: yes. I did work on one integration test for random DR method (setting seed to some specified value on the beginning), and on my Mac OS it gave one result, while on build servers (travis and shogun-buildbot) the results were different | 13:16 |
| lambday | HeikoS: alright... so for matrix function things, enum is fine, right? | 13:16 |
| @HeikoS | otherwise you will have to do all this switch(type) stuff which makes code hard to read | 13:16 |
| lambday | cause that method works for only sqrt, log and A^alpha | 13:16 |
| @lisitsyn | wiking: so openmp is in clang? | 13:16 |
| @HeikoS | lambday: exactly, we will only have a few there so thats fine | 13:16 |
| @wiking | vgorbati: that is rather fucking intersting :) | 13:16 |
| @HeikoS | let me check the rest of the mail ... | 13:16 |
| lambday | HeikoS: nice idea... okay :) | 13:16 |
| vgorbati | wiking: are you using linux? | 13:16 |
| @HeikoS | lambday: sorry for not responding too fast, I have a deadline coming btw ... | 13:16 |
| @wiking | vgorbati: osx | 13:17 |
| @HeikoS | lambday: could you maybe create a diagram for these things? | 13:17 |
| @HeikoS | just with inheritance and who references who | 13:17 |
| lambday | I've declared the enum in CContourIntegral.h instead, to avoid including unnecessary headers, in case one just want to use ContourIntegral and not RationalApproximation | 13:17 |
| @wiking | vgorbati: can u plz tell me where exactly you had the problem | 13:17 |
| lambday | HeikoS: sure... I'll mail it, changing the sampler as the base class | 13:17 |
| @wiking | vgorbati: the exact reason to have our own PRNG is that we dont have this problem anymore | 13:18 |
| @HeikoS | lambday: and maybe a small description for every class, like one sentence | 13:18 |
| -!- gsomix [~Miranda@r206-10.smr.ru] has joined #shogun | 13:18 | |
| gsomix | hello | 13:18 |
| @HeikoS | and method | 13:18 |
| @wiking | vgorbati: i.e. the seeded random is always the same, regardless of OS and arch | 13:18 |
| @HeikoS | so what does register do for example | 13:18 |
| lambday | HeikoS: alright... | 13:18 |
| vgorbati | wiking: ok, can you please try running "python generator.py converter_tdistributedstochasticneighborembedding_modular.py" in the "tests/integration/python_modular" and paste the file "data/testsuite/tests/converter_tdistributedstochasticneighborembedding_modular0.txt" somewhere? | 13:18 |
| @HeikoS | CComputation for example will also be a base class | 13:18 |
| @HeikoS | which is just used for registering problems (maybe make problem a class also) | 13:19 |
| @wiking | vgorbati: will do in a second | 13:19 |
| @HeikoS | only the implementation knows that there are shifts in the systems | 13:19 |
| vgorbati | wiking: you will need to un-blacklist the file 'converter_tdistributedstochasticneighborembedding_modular.py' in generator.py | 13:19 |
| @HeikoS | try to think as general as possible | 13:19 |
| @HeikoS | once we have the diagram, we can start moving things around (maybe attach the dia file so that I can modify it) | 13:19 |
| vgorbati | wiking: it is actually blacklisted 2 times :) | 13:19 |
| @HeikoS | lambday, we should spend some time on this, even before any code is written | 13:20 |
| lambday | HeikoS: alright... I'll send you by tonight... | 13:20 |
| @HeikoS | and then we should start adding concrete implementations in the diagram | 13:20 |
| @HeikoS | also before writing code | 13:20 |
| @HeikoS | also, keep in mind that everything has to be defined in terms of linear operators | 13:21 |
| @HeikoS | so when computing the matrix logarithm for example | 13:21 |
| @HeikoS | we always compute log(M)*v | 13:21 |
| @HeikoS | never log(M) alone (not possible sometimes) | 13:21 |
| lambday | yes... | 13:21 |
| lambday | hmm.. | 13:21 |
| @HeikoS | even for log-dets | 13:21 |
| @HeikoS | sometimes one cannot even store the matrix one wants to compute the log-det of | 13:21 |
| @HeikoS | but one can compute matrix-vector products of the parts for example | 13:22 |
| @HeikoS | so always linear operator apply, never a matrix on its own | 13:22 |
| lambday | hmmm... | 13:22 |
| sonne|work | wiking: if you want to use multiple threads for bagging | 13:24 |
| sonne|work | you should assign new SGParallel objects to the internal machine | 13:24 |
| sonne|work | not that it uses multiple threads | 13:24 |
| sonne|work | with nthreads = 1 | 13:25 |
| lambday | HeikoS: since computing shifts weights etc don't depend on the rest of the things, that things can be done now, may be? | 13:27 |
| @HeikoS | lambday: yes, if you want to code, then this can be done now :) | 13:27 |
| lambday | HeikoS: I hope I'll finish the coding for ContourIntegral thing by tonight/tomorrow.. and spend some time on designing the whole thing... | 13:28 |
| @HeikoS | lambday: okay, | 13:29 |
| gsomix | sonne|work: hi, working? :) | 13:29 |
| @HeikoS | lambday: again, I am slowing down things for the class structure to make it as flexible as possible | 13:29 |
| lambday | HeikoS: yes.. that's the best idea.. :) | 13:29 |
| sonne|work | gsomix: sure :D | 13:30 |
| gsomix | sonne|work: me too, sitting in the Lab. | 13:30 |
| lambday | HeikoS: could you please tell me what you have in mind about base CComputation class? What I thought was CSolver as a base class and then its subclasses implementing different solvers | 13:31 |
| @HeikoS | Computation and solver are different | 13:31 |
| @HeikoS | computation class has a register method where one can register subproblems (i.e. one linear system) in some structured way (i.e. all linear systems with indices) | 13:32 |
| @HeikoS | the computation class then has an abstract method compute which then solves all registered problems somehow | 13:32 |
| @HeikoS | note that registering might differ in subclasses (i.e. register a shifts vector) | 13:32 |
| @HeikoS | the solver class just solves a linear system | 13:33 |
| @HeikoS | and might be used by the computation class impleentations | 13:33 |
| @HeikoS | does that make sense? | 13:33 |
| lambday | HeikoS: yes... okay | 13:34 |
| lambday | HeikoS: alright... this helped a lot... I'll mail you the diagram... | 13:37 |
| @HeikoS | good :) | 13:37 |
| thoralf | HeikoS, sonne|work: You wrote lib/DynamicObjectArray.h, right? | 13:42 |
| thoralf | Can you explain, why you always do SG_REF before returning a reference, e.g. in get_element()? | 13:42 |
| @HeikoS | thoralf: this is done everywhere in shohun | 13:43 |
| @HeikoS | shogun | 13:43 |
| @HeikoS | whenever you get an element, you store it, so the ref-counter has to be incremented | 13:43 |
| -!- sumit [75cf9448@gateway/web/freenode/ip.117.207.148.72] has joined #shogun | 13:44 | |
| sonne|work | thoralf: in python & swig you need a way to tell whether an object is still used | 13:44 |
| thoralf | HeikoS: Okay, that means I can rely that a returned reference has been SG_REF and I need to care about SG_UNREF? | 13:44 |
| sonne|work | thoralf: this is done via reference counts | 13:44 |
| sonne|work | so whenever we return an object | 13:45 |
| sonne|work | python & swig calls ref() | 13:45 |
| @HeikoS | thoralf, yes you have to unref to prevent leaks | 13:45 |
| sonne|work | when swig is done using the object | 13:45 |
| sonne|work | it calls unref() | 13:46 |
| @HeikoS | thoralf: this is done most of the time, sometimes, we forgot SG_REF, in this case, send a bug report :) | 13:46 |
| sonne|work | once the refcount (via unref reaches 0) | 13:46 |
| @wiking | sonne|work: will check | 13:46 |
| thoralf | sonne|work: Maybe I don't store the reference, but only pass then to a method which cares about ref/unref by itself. | 13:46 |
| thoralf | sonne|work: So I always need to store the reference in a variable and UNREF it afterwards. | 13:46 |
| thoralf | sonne|work: Yeah, I know. I just wasn't aware of this kind of "convention". :) | 13:48 |
| sonne|work | thoralf: yes | 13:48 |
| sonne|work | this also works the other way round | 13:48 |
| sonne|work | if you create say some feature object | 13:49 |
| sonne|work | you can pass this directly into some machine | 13:49 |
| sonne|work | then an unref of the machine will also erase the feature object | 13:49 |
| thoralf | sonne|work: So I can't do calls like method_eats_ref( object->method_returns_ref() ) | 13:49 |
| thoralf | sonne|work: I always need addional code just for ref-counting. :) | 13:50 |
| thoralf | sonne|work: One example: kernel->set_features( ref_to_my_features ); | 13:51 |
| thoralf | sonne|work: Do I need to care about SG_UNREF of the passed object or not? | 13:51 |
| @wiking | sonne|work: for feature/label selection with replacement, can i use the subset thingy? | 13:51 |
| thoralf | sonne|work: I always do SG_REF() after creation and SG_UNREF() in the end - but after what you told, this is not neccessary? Just pass into ->set_features() and stop caring? | 13:53 |
| sonne|work | thoralf: for kernel->set_features( ref_to_my_features ); you don't need to SG_REF(ref_to_my_features) after you created them and if you don't touch them later | 13:57 |
| sonne|work | so e.g. kernel->set_features(new DenseFeatures<float64_t>()) | 13:58 |
| sonne|work | but for your method_eats_ref( object->method_returns_ref() ) you need to store the object and unref | 13:59 |
| thoralf | sonne|work: Thanks, that answers my questions. | 14:00 |
| sonne|work | wiking: I think not - hmmh HeikoS - maybe we have conflicts then right? | 14:00 |
| sonne|work | thoralf: btw we cannot return lazy copies (not SG_REF'd) | 14:01 |
| sonne|work | or swig interfaces will have memory leaks | 14:01 |
| thoralf | sonne|work: Thats alright. I just assumed, you only count references when copying objects and I have to care about references by myself. | 14:05 |
| sonne|work | wiking: actually you can do it! | 14:07 |
| sonne|work | wiking: just do add_subset | 14:07 |
| sonne|work | and once done remove_subset | 14:07 |
| thoralf | sonne|work: Btw, I think it would make sense to initialize "new SGVector<T>(len)" with zeros in the constructor, i.e. zero(); right after the SG_MALLOC. | 14:09 |
| @wiking | sonne|work: mmm but can i have replacement there? | 14:10 |
| sonne|work | thoralf: we could use SG_CALLOC for that but it is not done to have a speed gain in case you just want to alloc some vector and assign values... | 14:10 |
| thoralf | sonne|work: valgrind told me something about uninitialized variables - and I think the fix would be trivial | 14:10 |
| sonne|work | wiking: replacement? | 14:10 |
| @wiking | sonne|work: or the index vector can be whatever, i.e. i can have in index vector the same index as many times as i want | 14:10 |
| @wiking | sonne|work: "each of size n′ < n, by sampling from D uniformly and with replacement" | 14:11 |
| sonne|work | wiking: sure why not! | 14:11 |
| sonne|work | just the same size! | 14:11 |
| @wiking | ok cool | 14:11 |
| @wiking | yeah sure ;) | 14:11 |
| sonne|work | no actually any n' <= n yes | 14:11 |
| sonne|work | wiking: if you do that better extract the sampling strategies | 14:12 |
| sonne|work | like random subset / bagging etc | 14:12 |
| @wiking | ? | 14:12 |
| sonne|work | no idea what the official name for sampling strategy is | 14:12 |
| sonne|work | maybe heiko knows | 14:12 |
| sonne|work | HeikoS: ^? | 14:12 |
| @wiking | well i'll just do random selection | 14:12 |
| sonne|work | wiking: well there are various strategies for sampling | 14:13 |
| @HeikoS | ehm what? | 14:13 |
| @wiking | mmm | 14:13 |
| @HeikoS | sampling what? | 14:13 |
| @wiking | sonne|work: really? | 14:13 |
| @wiking | sonne|work: here it said only that uniform random with replacement | 14:13 |
| @wiking | HeikoS: bagging | 14:13 |
| sonne|work | HeikoS: wiking is building some classifier that is trained a couple of times on subsets of the data | 14:13 |
| @HeikoS | random forests? | 14:13 |
| sonne|work | the way this subset is generated should be generalized | 14:13 |
| sonne|work | yes for that | 14:14 |
| sonne|work | but it will work for anything | 14:14 |
| @HeikoS | well then the samples have to be independent | 14:14 |
| sonne|work | and there are various strategies for sampling | 14:14 |
| @HeikoS | so with repetitions | 14:14 |
| sonne|work | like uniform / stratified / repetitions etc | 14:14 |
| sonne|work | so we might want to generalize this somehow | 14:14 |
| @wiking | now the only question is that whether all our CMachine implementations has clone() function implemented | 14:19 |
| sonne|work | wiking: surely not :D | 14:23 |
| sonne|work | wiking: but what do you need clone for? | 14:23 |
| sonne|work | ohh I see | 14:24 |
| @wiking | sonne|work: how else i'm going to create a bag of defined machines | 14:24 |
| thoralf | What's the difference between left_features and right_features in kernel->init(left, right)? | 14:32 |

| sonne|work | thoralf: well rows, columns | 14:39 |
| sonne|work | thoralf: so for training you do k(X,X) and for testing k(X,X_test) | 14:39 |
| thoralf | sonne|work: Thanks. | 14:39 |
| thoralf | sonne|work: That explains why the cache is only initialized for lhs. | 14:40 |

| @wiking | sonne|work: and i really wonder how this should work in case of a kernel machine? : | 14:53 |
| @wiking | :P | 14:53 |
| sonne|work | wiking: ohh I realize parameters of the machine need to be set already | 14:54 |
| sonne|work | I mean fully | 14:54 |
| sonne|work | wiking: so you need in case of a kernelmachine, the kernel, its parameters and the kernel machine and its parameters already set | 14:55 |
| sonne|work | then take that machine and train with different subsets | 14:55 |
| sonne|work | wiking: for now just do it this way but not parallel at all | 14:56 |

| @HeikoS | sonne|work, wiking clone should be done via parameter framework, please dont start writing custom clone methods for all classes, this wil be a mess | 15:11 |
| sonne|work | HeikoS, wiking - well wikign doesn't need clone as long as he runs everything *single* threaded | 15:12 |
| @HeikoS | okey | 15:12 |
| @HeikoS | I see | 15:12 |
| @HeikoS | similar to grid-search stuff | 15:12 |
| sonne|work | yeah | 15:13 |
| gsomix | <offtop>https://dl.dropboxusercontent.com/u/19029407/results_of_raytracing.png<\offtop> | 15:20 |
| gsomix | ahh, braces... :) | 15:21 |
| @wiking | sonne|work: ok but how do i save the different models? | 15:44 |
| @wiking | sonne|work: because later i'll have to apply the features on those different models | 15:44 |
| sonne|work | wiking: ohh indeed | 15:46 |
| sonne|work | HeikoS: any suggestions? I mean this certainly needs store_model_features | 15:47 |
| @HeikoS | what about serialising? | 15:48 |
| @HeikoS | to a byte stream | 15:48 |
| @HeikoS | ah no | 15:48 |
| @HeikoS | sorry | 15:48 |
| @HeikoS | so multple subsets on the same machine | 15:48 |
| @HeikoS | thats not trivial | 15:49 |
| @HeikoS | store_model_features has to be extended | 15:49 |
| @wiking | sonne|work: btw: random forest is not a simple bagging machine. as it splits the data set vertically as well not only horizontally | 15:51 |
| @wiking | i.e. bagging just splits the dataset into smaller bags... but random forest splits the data set by feature dim | 15:52 |
| sonne|work | wiking: both at once? | 15:53 |
| @wiking | each tree gets n < m features where m is the feature dim of the original dataset | 15:53 |
| @wiking | "Each tree is trained on a bootstrapped sample of the original data set." | 15:54 |
| @wiking | "Each time a leaf is split, only a randomly chosen subset of the dimensions are considered for splitting." | 15:54 |
| @wiking | anyhow for bagging we need to be able to clone machines or something like that | 15:54 |
