pranetHow do i invoke the tests after writing them?07:32
@wikingpranet: add the source to ./tests/unit/<whichever dir fits the best>/<classname>_unittest.cc07:52
@wikingand then just re-run cmake07:52
@wikingmake sure u have -DENABLE_TESTING=ON given for cmake07:52
@wikingand after that just run make && ctest07:52

lambdayHeikoS: there?22:24
@HeikoSlambday: half :)22:28
@HeikoSlambday: how are things?22:28
lambdayHeikoS: surveying the code...22:28
@HeikoSlambday: how horrible is it? :)22:29
lambdayHeikoS: umm.. too soon to tell.. :) at a first glance, HSIC bootstrap_null uses its kernel-independence-test-statistic's bootstrap_null and that permutes the whole thing over p and q... so trying to think how to fit things when I split its parent class22:30
@HeikoSlambday: yeah the split basically implements the bootstrap_null (realy should be called l sample_null) differently22:33
lambdayHeikoS: let me check, I will get back with some queries..22:35
@HeikoSlambday: sure!22:42
@HeikoSlambday: btw dino and I have big plans for this project22:42
@HeikoSwith paper and loads of experiments being done with the implementation etc :)22:42
lambdayHeikoS: great! :D the topic is really appealing - so much to learn! will work hard!22:44

ahcordeHello, i'm working in the integration of Opencv and Shogun. I'm making a basic facial recognition example, as an entrance task (eigenfaces).  I have a SGMatrix<float64_t> featuresVector and I would like o use PCA, but when I execute     shogun::CPCA* pca = new shogun::CPCA(); pca->init(featuresVector) takes a long time. Any ideas? thank you23:34
-!- lambday [67157d4e@gateway/web/freenode/ip.103.21.125.78] has quit [Ping timeout: 245 seconds]23:35
ahcordethe featuresVector have two vector and 10304 features Images size ( 92x112)23:36
-!- HeikoS1 [~heiko@nat-177-195.internal.eduroam.ucl.ac.uk] has joined #shogun23:38
ahcordefeatureVector is CDenseFeatures sorry23:38

ahcordeI have a     CDenseFeatures<float64_t>*  and would like to use PCA with this matrix,   but when I execute CPCA::init takes a long time.23:42
HeikoS1ahcorde: how big is your matrix?23:43
HeikoS1what are the dimensions?23:43
ahcorde10304 features x 2 vectors23:43
HeikoS1just two vectors?23:44
HeikoS1PCA cannot help you with 2 vectors23:44
HeikoS1or do you do that for a test only?23:44
HeikoS1ahcorde: we actually will soon update our PCA implementation to deal with D>>N problems efficiently, the current one takes a long time for such a problem23:44
HeikoS1ahcorde: there is an GSoC entry task on that in our github issue list, have a look23:45

lisitsyn1okay I am powering off23:50
