thoralfHey guys.12:35
@iglesiasgHi thoralf12:36
thoralfHeikoS: I've thought about the test generator.  What about using GCCXML to parse the header files, extract all possible constructors and indeed run automatic tests if we can handle the parameters.12:38
thoralfHeikoS: For example we could handle int32_t, SGMatrix, etc.12:38
@HeikoSthoralf: I also had another idea yesterday night12:39
@HeikoSthoralf: since some classes need special types of input12:39
@HeikoSi.e. not just a matrix but a psd matrix12:39
@HeikoSthis is very hard to handle automatically12:39
@HeikoSbut we could do a hybrid approach12:39
thoralfpsd?12:39
@HeikoSpositive matrix12:39
thoralfAh.12:39
@HeikoSsay CSGobject gets an abstract method that creates a non-trivial instance12:40
@HeikoSthen developers are forced to create this12:40
@HeikoSwhich makes sense since they know how a non-trivial instance looks like12:40
@HeikoSexample:12:40
@HeikoSCSGObject* get_non_trivial_instance()12:41
@HeikoSfor dense features12:41
thoralfHeikoS: This limits us to one instance.12:41
@HeikoSthis could just create a random matrix, add a subset and a preprocessor and return12:41
@HeikoSthoralf: yes, but the instance makes sense since its not generated automatically12:41
@HeikoSthoralf: we can easily return a list and if people want to test more, they can do that12:41
@HeikoSthoralf: this way we can have all the tests that can be automated, serialisation, equals/clone12:42
@HeikoSbut working on non-trivial instances12:42
thoralfHeikoS: Why so complicated? ;)12:42
@HeikoSwhile these are handwritten12:42
thoralfHeikoS: I won't change existing classes for this.12:42
@HeikoSthoralf: yes thats the downside12:42
thoralfHeikoS: We're messing up design for automatic test generator.12:42
@HeikoSthoralf: but since our classes are quite diverse I dont know about automagic tests12:42
@HeikoSthere are constraints on the data you can give to a class12:43
@HeikoSand what actually appears in practice12:43
@HeikoSif we do this via types we might run into problems12:43
@HeikoSthoralf: oh and btw we can stack this get_non_trivial instance12:43
@HeikoSfor example an svm can simply call DenseFeatures::get_non_trivial instance12:43
@HeikoSthoralf: but I am open for other approaches12:44
@HeikoSthoralf: maybe good to discuss this also with lisitsyn and wiking12:44
@HeikoSthoralf: you can also start a discussion on github issues, we havve a new label: "things to discuss"12:44

@HeikoSthoralf: gotta do some work now, be back later today :)12:44
thoralfHeikoS: One second please. ;)12:45
@HeikoSthoralf: ok :)12:45
thoralfHeikoS: My idea would be a simple class for generating examples.  For example several SGMatrix instances.  Each provided by a simple method "generator_1x1_matrix()", etc.  We then can simply use this for automagic code generation.  All we need to know is: Possible classes+their constructors *and* possible data generators.12:46

thoralfHeikoS: Both can be found with gccxml and be parsed with python.12:47
@HeikoSthoralf: SGmatrix cannot be tested automatically btw12:47
@HeikoShow would that work for example for an SVM with all its parameters12:47
@HeikoSwe then have to define those methods for every class, right?12:47
thoralfHeikoS: Yes and no.12:47

thoralfIf we find a class LibLinear(int, dotfeatures, labels), we can just insert the example data for each parameter,12:49
@HeikoSthoralf: so we have to define all types anyway12:50
@HeikoSthoralf: why then not do this within a class, much less hacking and effectively the same12:50
@HeikoSthoralf: and actually modular since one can stack things12:50
thoralfHeikoS: We only define the types we want to support.12:50
@HeikoSthoralf: all CSGObjects12:51
thoralfHeikoS: I think the tests are not part of shogun, so keep them out of the classes.12:51
@HeikoSthoralf: thats true!12:51
thoralfHeikoS: They're just QA code.12:51
@HeikoSthoralf: maybe define this in another file then12:52
thoralfHeikoS: But what about OO?  Just overloading?12:52
@HeikoSthoralf: yes12:52
thoralfHeikoS: SGMatrixTestClass1 ;)12:52
thoralfextends SGMatrix12:52
@HeikoSthoralf: no one can add methods in other files12:52
@HeikoSSGMatrix cannot be tested this way anyway12:52
@HeikoSonly SGObjet instances12:52
thoralfOh.12:53
thoralfYes.12:53

pickle27hey guys17:40
pickle27I have a question17:40
pickle27is there a way with shogun to test if an SGMatrix is positive definite?17:40
-!- FSCV [~FSCV@50.7.50.60] has quit [Quit: Leaving]17:41
pickle27and if there isn't I'd like to add one, should this be a member of SGMatrix or a function in one of the modules17:41

thoralfWhat happens, if I create an object on the stack and pass a reference inside a method which calls SG_REF/SG_UNREF?17:53
thoralfCan shoguns reference counting handle this?17:54
thoralfI'm getting strange errors at the end of the scope.17:55

lambdayHeikoS: hehe :D19:01
lambdayHeikoS: umm things are good19:01
lambdayHeikoS: will add COCG_M19:01
lambdayHeikoS: one thing about the eigensolver19:01
@HeikoSlambday: yes?19:01
lambdayHeikoS: what shall we use for the tridigonal solver for Lanczos?19:02
lambdaytridiagonal*19:02
lambdaykrylstat uses alglib19:02
@HeikoSlambday: alglib has a tringular solver?19:02
@HeikoSis it for sparse or dense things?19:02
@HeikoSdoesnt eigen have a triangular solver?19:03
@HeikoSI remember erlend mentioning this was tricky to do with eigen19:03
lambdayI am not sure about whether eigen3 has it or not19:03
lambdaythere are several implementations of lanczos19:04
lambdayone of them I found from the link that lisitsyn gave the other day19:04
lambdayHeikoS: https://github.com/lambday/KRYLSTAT/blob/master/lanczos/eigen/eigen_lanczos.h#L14319:05
lambdaythis is where they use this function smatrixtdevd19:06
lambdaythat's in alglib19:06
lambdayI think it uses lapack inside it, since we already had lapack support, I can study what it does inside19:06
lambday:-/19:06
@HeikoSwe are talking about a triangular solver right?19:08
@HeikoSisnt that easy?19:08
@HeikoSjust sustitide back in?19:08
@HeikoSthere must be a lib for  this somewhere ;)19:08
@HeikoSmaybe have a look into alglib19:08
@HeikoSwe are using that one quite a bit already19:08
@HeikoSso no problem19:09
@HeikoSporting the functions to shogun is a bit painful though19:09
@HeikoSbut alglib is very mature19:09
lambdayHeikoS: we do have alglib support?19:12
lambdaythat's awesome then...19:12
@HeikoSlambday: we copy/paste code from algib19:12
@HeikoSsupporting it is impossible19:12
lambdayohh :D19:12
@HeikoSbut we do proper porting of selected parts19:12
@HeikoShave a look into CStatistics19:12
@HeikoSmany things in there use alglib19:12
@HeikoSCDF functions, GAMMA etc19:12
@HeikoSintegrals19:12
lambdayokay I'll check19:13
lambdayif that doesn't work, will write from scratch19:13
@HeikoSlambday: no use the algli one19:14
@HeikoSyou just have to replace some functions19:14
@HeikoSlike abs,exp,sin etc19:14
@HeikoSyou will see it19:14
@HeikoSstudy an existing function before you do this, then you know what do to19:14
lambdayokay I'm checking19:14
@lisitsynHeikoS: re!19:38
@lisitsynwhat's up?19:38
@HeikoSlisitsyn: what about the templates for the tests?19:41
@HeikoSlisitsyn:  sorry gotta go soon19:42
@lisitsynHeikoS: but they are here no?19:42
@HeikoSlisitsyn:  ah did not see :)19:43
@HeikoSsorry busy day19:43
@lisitsynHeikoS: hehe19:43
@lisitsynHeikoS: the problem is that they fail19:43
@lisitsynI'll spend some time starting from now to check19:43

pickle27lisitsyn: good!19:59
pickle27did you see my question about the pos def matrix check?20:00
@lisitsynpickle27: yeah I don't think we have anything for that20:00
@lisitsynpickle27: do you know anything faster than computing eigenvalues btw?20:00
pickle27lisitsyn: I don't, I think that might be the only way?20:01
@lisitsynI guess so20:01
pickle27lisitsyn: what do you think about adding a member to SGMatrix that checks if it is pos def20:02
@lisitsynpickle27: I am ok with it20:03
pickle27lisitsyn: okay I might add one then20:03
pickle27it actually won't really help me where I needed it but it might come in handy later or for someone else20:03
pickle27are unit tests broken at the moment?20:06
@lisitsynpickle27: yeah a bit20:11
pickle27kk20:11
pickle27lisitsyn: sent a PR fixing Jade20:13
@lisitsynpickle27: I find JointDiago name a bit strange, do you?20:15
pickle27yeah I do20:15
@lisitsynpickle27: and this givens etc thing20:16
@lisitsyncould you please correct the naming20:16
@lisitsynlet me comment in code20:16
pickle27Im just not sure what else to call it20:16
pickle27its mostly a direct port from the authors release20:16
@lisitsynpickle27: may be just CJointDiagonalizer?20:17
pickle27perhaps20:18
pickle27we could also ask Andreas what he thinks we should call it20:18
@lisitsynsure why not20:18

@iglesiasgsonney2k, lisitsyn, HeikoS : isn't it a big limitation that SGObjects can never be used in stack?21:14
@iglesiasgwiking: ^21:14
@lisitsyniglesiasg: like21:14
@lisitsynSGObject?21:14
@iglesiasglisitsyn: I am referring to https://github.com/shogun-toolbox/shogun/issues/126821:15
@lisitsyniglesiasg: well such thing disables polymorphism21:16
@iglesiasgtrue21:17
@iglesiasglisitsyn: but one might one to have something in the stack for performance reasons21:17
@iglesiasglisitsyn: or is there no real difference in practice?21:18
@lisitsynno I don't think it is relevant21:18
@lisitsynyou won't notice I believe21:18
@sonney2kgsomix, you can use SG_REALLOC for that - maybe it is easiest to add a add_columns() / remove_columns() function to SGMatrix and then read in a few MB at a time21:33
@iglesiasggsomix: do you need to add and/or remove columns in a SGMatrix? Maybe the subset can help you to do that21:35
gsomixiglesiasg, yeah, I need to add. for reading matrices from file.21:35
gsomixgood evening21:36
@iglesiasgin my LMNN code I am using subsets to do something like this21:36
@iglesiasgsay you have a matrix like [1 2 3 4 5]21:36
@iglesiasgwhere 1 2 3 ... denote full columns (with several rows), not just a number21:37
@iglesiasgand you want to get stuff like21:37
@iglesiasg[2 3 5]21:37
@sonney2kiglesiasg, actually keeping things on stack is dangerous and calling for stack overflow errors21:38
@iglesiasgsonney2k: really? isn't it like insane amount of variables in stack required for it to overflow?21:39
@lisitsynsonney2k: I can't imagine stack overflow on modern computers21:39
@sonney2kiglesiasg, unfortunately not - I experienced that several times21:39
@iglesiasglisitsyn: with recursion is easy21:39
@lisitsynwith reasonable code21:39
@sonney2kno recursions21:39
@iglesiasgsonney2k: I have experienced using recursion but not because of allocating variables21:39
@iglesiasgand even with recursion it was because there was a bug :)21:40
@lisitsynwell actually I'd love to see shogun objects as pimpl21:41
@lisitsynjust wrappers for pointer to implementation21:41
@lisitsynlike smartpointer but not a smartpointer21:41

gsomixsonney2k, ok, reading of vectors from csv works fine22:25
gsomixtoday I have implemented StringReader - the class over SGVector<char> and CTokenizer with some useful methods like read_int(), etc.22:27
@sonney2kgsomix, I had another idea - you could add a method to create a SGMatrix from a SGVector giving it some dimensions22:33
@sonney2kgsomix, so you could just extend the vector all the time with resize22:33
gsomixsonney2k, btw, number of rows I should define by first line in csv file, right? and number of lines then == number of columns22:38
gsomixsonney2k, I like your idea. but now  we don't have nor SGMatrix or SGVector in File interface - just pure arrays.22:41
@sonney2kgsomix, there is no 'true' ordering for matrices. I guess22:45
@sonney2kwe need to support both22:45
@sonney2kas in22:45
@sonney2k1 row == 1 column vector22:45
@sonney2kand 1 row == 1 row vector22:45
gsomixsonney2k, ok22:48
