sakethow do we run examples in the folder examples/documented/libshogun ?07:27
saketCompiling them with "  g++ classifier_nearest_centroid.cpp -lshogun "07:27
saketgive this error classifier_nearest_centroid.cpp:1:36: fatal error: shogun/features/Labels.h: No such file or directory07:28
saketdo i need to give some parameter to ./configure07:28
votjakovrsaket: Hi, Have you installed shogun by running 'make install'?07:32
saketvotjakovr: yes i did07:34
saketother examples do compiel07:34
saket*compile07:34
saketbut on running i get error while loading shared libraries: libshogun.so.14: cannot open shared object file: No such file or directory07:35
saketI think i need to append path to libshogun.so.14 to some env variable..right? any idea ?07:36
saketgot it ..needed to add the path to /etc/ld.so.conf07:44
votjakovrsaket: great :)07:45
votjakovrsaket: I think you can't compile classifier_nearest_centroid.cpp, because Labels.h in shogun/labels/ now07:46
saketoh07:48
saketshall i move it ?07:48
votjakovrsaket: No, I don't think so...07:49
saketvotjakovr: I will be grateful to you if can help me out with the v_array issue .. i mail yesterday to the mailing list07:50

sijin@lisitsyn  hello, do you have time now?10:30
@lisitsynsijin: yes a bit10:30
sijinI have modified takpee_shogun.cpp/tapkee_shogun.hpp for support of KPCA and retriving projecting function, could you please check it? If it is ok, i can move to writing the warper10:31
sijinSince projecting_func->implemtation is NULL currently, I can't test the program by myself10:32
@lisitsynsijin: I am doing some changes in that code last days10:32
@lisitsynyes10:32
@lisitsynthat's a blocker for changing kpca to use tapkee10:32
@lisitsynI will test things tonight and commit10:32
sijinAlso, I notice that kpca has get_transformation_matrix(),10:33
@lisitsynit is kind of bad naming for me10:34
sijincan projecting function provide that? or I would like to delete this member function from that class10:35
@lisitsynlets get back to that once I prepare some things10:36
sijinok.10:36

@lisitsynalright11:39
@wikingok11:39
@wikingwho knows anything about this script: classifier_averaged_perceptron_modular.py11:39
@wiking?11:39
@wikingas in the integration test for it11:40
@lisitsynwiking: does it fail?11:40
@wikingw SGVector<float64> 2 ({0.5}{0.5})11:40
@wikingvs11:40
@wikingw SGVector<float64> 2 ({0.49}{1.160182291326443e+75})11:40
@HeikoSwiking: I thought I fixed the seed for that?11:41
@HeikoSsince when does it fail?11:41
@wikinga is the last one b is the [D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[D[C[C[C[C[C[C[C[C[C[C[C[C[C[C[C [C is in a and the first one in [C[C[C[C[C[C[C[C[C11:41
@HeikoSmaybe its the labelss that I changed?11:41
@HeikoSwiking: ehm?11:41
@wikingmmm shit11:41
@wikingsorry something went wrong11:41
@wikinganyhow11:42
@wikingb is this one data/testsuite/tests/classifier_averaged_perceptron_modular0.txt11:42
@wikingi.e. the first one with w SGVector<float64> 2 ({0.5}{0.5})11:43
@wikingand the other one is generated on my machine11:43
@wikingand of course since they are not the same11:44
@wikingthe integration test fails11:44
@HeikoSwiking:  are the seeds fixed?11:44
@wikingHeikoS: dunno11:44
@wikingthe only thing i know is that i compiled the code11:45
@wikingfrom the HEAD11:45
@wikingdevelop branch11:45
@HeikoScheck the code pls11:45
@wikingHeikoS: where what?11:45
@HeikoSclassifier_averaged_perceptron_modular.py11:46
@HeikoSpython modular11:46
@HeikoSwiking: tests work fine here11:46
@wikingHeikoS: ok what should be there?11:46
@HeikoSlast compiled yesterday11:46
@HeikoSwiking: fixed seeds for python numpy and shogun11:46
@wikingrandom.seed(seed)11:46
@wikingseed=111:46
@wikingif u mean that11:46
@HeikoSyes11:47
@wikingwell it's there11:47
@HeikoSok11:47
@HeikoSmmh11:47
@HeikoSno idea then11:47
@wikingbut still it fails11:47
@HeikoSjust pulled and compiling11:47
@wikingand not only this11:47
@HeikoSwill try agian11:47
@wikingbut a lot other11:47
@HeikoSI also have some tests locally failing11:47
@HeikoSsince I have not all libs installed11:47
@wikingok so here's a list of failing integration tests on osx: http://pastebin.com/sAbq05kN11:49
@HeikoSwiking:  there must be something wrong11:50
@HeikoSI recently broke all tests11:50
@HeikoSbut corrected afterwards11:50
@HeikoSso maybe non uptpdate code?11:50
@wikingHeikoS: i've tried11:50
@wikingbut no help11:50
@HeikoSWarning: program compiled against libxml 209 using older 20711:50
@HeikoSweird11:50
@wikinggit pull && make clean && ./configure && make install11:50
@HeikoSgit pull --rebase upstream develop11:51
@HeikoSthats what I do11:51
@HeikoSwhile being in dev branch11:51
@wikingf2dae9dbaa0b8fbf34b01c5bb53a3108986e418411:51
@wikingthis is my last commit in dev branch11:51
@wikingand that's the last one in github as well11:51
@HeikoSf2dae9dbaa0b8fbf34b01c5bb53a3108986e418411:52
@HeikoSyes11:52
@HeikoSmine too11:52
@HeikoSstrange!11:52
@HeikoSbut no idea, probably mac stuff11:52
@wikingi guess so11:52
@HeikoSwiking: sorry, I have to do some work now, see you!11:53
@wikingbut still then i guess this could be a background for why one integration test fails on travis11:53
@wikingokok cya11:53
@HeikoSwiking: yes good point!11:53
@lisitsynvgorbati: ping11:55
vgorbatiisitsyn: yes, I saw the test failure - guess it was that 1e-5 probability. Make the number smaller?11:56
vgorbatilisitsyn:or another way - the things are much better, when target_dim==initial. I can make it so..11:57
@lisitsynvgorbati: yes please11:58
vgorbatilisitsyn: yes for the second option?11:58
@lisitsynvgorbati: yes11:59
@lisitsynand we could change the data actually11:59
@lisitsynvgorbati: you may try some displaced grid in 2d12:00
vgorbatilisitsyn: to predefined? I guess I can generate one matrix randomly, see the minimum intersection rate, save the matrix to file, and the read it during the test. Then there wont be any randomness (is ther such a word)12:00
@lisitsynvgorbati: heh, well we are of nearly the same native language so I understand your words (about your wondering if there is such a word)12:01
@lisitsynvgorbati: err not in 2d but 3d12:01
@lisitsynx = [0,0.001,....,1]12:02
@lisitsyny = [0,0.001,...,1]12:02
@lisitsynz = some noise12:02
@lisitsynthis should preserve neighborhoods much more12:02
vgorbatilisitsyn: and project that to 2D?12:02
vgorbatilisitsyn: i mean embed12:03
@lisitsynyes12:03
@lisitsynvgorbati: do you feel the difference btw?12:03
@lisitsynit is actually pretty the same but it looks better to say 'project' about PCA12:03
vgorbatilisitsyn: in data? there's a linear dependenc12:03
@lisitsynand 'embed' for some non-linear thing like LLE12:04
@lisitsynvgorbati: anyway please take a look12:04
vgorbatilisitsyn: yes, I did feel that it is wrong to say 'project' for non-linear embedding methods12:04
vgorbatilisitsyn: ok, I will take a look after an hour I guess12:05

deerishii am just gonna give the pull request.14:25
@HeikoSdeerishi: did you put the data generator into tools?14:25
@HeikoSand import it from both the modular and the graphical ex?14:25
deerishinope.by data generator do you mean the circular data.14:25
deerishi?14:25
deerishiin tools do i jyst need to write import preprocessor_kernel.py and import preprocessor_kernel_graphical.py?14:26
@HeikoSdeerishi: no14:26
@HeikoSyou import the circle data from the examples14:27
@HeikoSnot the other way round14:27
@HeikoSand please rename the files to preprocessor_kpca ...14:27
@HeikoSkernel doesnt mean much :)14:27
deerishim still a bit unsure abt what i need to do in the tools folder . i have done  shogun / examples / undocumented / python_modular ---->The KPCA CODE: preprocessor_kpca.py shogun / examples / undocumented / python_modular / graphical ----->The circular input data: preprocessor_kpca_graphical.py14:28
@HeikoSyou generate your data with some function in a file right?14:29
@HeikoSthat has to go to the tools folder14:29
@HeikoSthen, both examples import this file to generate data14:29
@HeikoSone example plots, the other one doesnt14:30
@HeikoSmakes three files14:30
@HeikoS1) circle_data.py - located in python_modular/tools14:31
@HeikoS2) modular example - located in python_modular, imports 114:31
@HeikoS3) graphicla example - located in python_modular/graphical, imports 1, plots14:31
deerishik.i think i got it.it was a slight misunderstanding on my part. the data generation file goes to the tools folder..14:31

vgorbatilisitsyn: sure, but debugging using cout<< is soo painful)14:50
@lisitsynvgorbati: well you may try gdb or anything like that :)14:50
Yanglittlein the grid search, assuming the gaussian kernel, there are two parameters, delta and C. this is no problem. But in mkl_multiclass, assuming five gaussian kernels, and it needs to find five different delta and a C, does grid_serach can support this?14:53
@lisitsynahh14:53
@lisitsynHeikoS: ^ could you please comment that?14:54
@HeikoSYanglittle: in MKL you usually do not optimize over kernel parameters but just put in a set of kernels and then look at the weights14:55
@HeikoSMKL solves for the weights for you14:55
@HeikoSthen you only do a gridsearch over C14:55
@HeikoS5 different kernel parameters also is completely infeasible14:55
@HeikoSparams_per_kernel^5 * C_possiilities14:55
@lisitsynactually it sounds exp yeah14:57
Yanglittleyes i know this but when calculate the single kernel, we search a good pair of delta and C, but the good delta may not be the best for the mkl_multiclass. what do you think?14:59
vgorbatilisitsyn: i am having troubles on how to use gdb. Ok, I added -g option in makefile, so that now 'shogun-unit-test' executable contains debug info. Ok, I can run 'gdb shogun-unit-test'. But then, how do I break the execution in needed test?15:05

Yanglittlei want to make each subkernel get a good accuracy on the data. and so , is it beneficial for mkl? in mkl, each subkernel needs the width, and how to determine the width?15:30
@HeikoSYanglittle: you don't select the width but rather throw some kernels at the MKL which then discards the unimportant ones via the weights.15:43
@HeikoSYanglittle: also if one single kernel is best for your problem, then all MKL kernels will have the same width15:47

@lisitsynvgorbati: yes16:14
vgorbatilisitsyn: is it possible that embedding shuffles columns a bit? Then the picture will look right, but neighbor indices not16:14
@lisitsynvgorbati: columns like vectors?16:15
vgorbatilisitsyn: yes, feature vectors16:16
@lisitsynno, the order is preserved16:16

@HeikoSlisitsyn: I can understand the discussion though16:25
@lisitsynHeikoS: I am quite opposite to that - citizens are responsible for their country16:27
@HeikoSlisitsyn: still the reaction is understandable - it counters the open-source principle16:27
@HeikoSwhile google has a point16:27
@HeikoSand they cannot do anything anyway16:28
@HeikoSso ....16:28
@lisitsynHeikoS: do you think it does counter that?16:28
@lisitsynI mean open-source is not about gsoc16:28
@HeikoSyes16:28
@lisitsynnobody can ever deny open-source16:28
@HeikoSbut gsoc is about open-source16:28
@HeikoSanyway, doesnt matter16:28
@HeikoSgoogle cannot chang eit16:29
@lisitsynit is about funding which comes from google16:29

Yanglittlein the grid_search, how can i get the array of the build_values? It seems no the method.16:50
@HeikoSYanglittle: no there is no method, you can print the parameter tree though16:53
vgorbatilisitsyn: so I checked really carefully, and it looks like the test is also ok. The thing is, that for every point there are sometimes a lot of points nearly at the same distance to it - and when we embed them, this distances change slightly, that can't be seen visually, but actually changes nearest neighbors16:55
