AndreLopesHi01:26
AndreLopes../examples/documented/java_modular/classifier_averaged_perceptron_modular.java01:26
AndreLopesIn this example01:26
AndreLopesI got a warning01:26
AndreLopes[WARN] In file /builddir/build/BUILD/shogun-96f3cf3ce58514299f98e688b7c43e057ad4fa41/src/shogun/classifier/AveragedPerceptron.cpp line 90: Averaged Perceptron algorithm did not converge after 10 iterations.01:28
AndreLopesIs this normal to the example ?01:28
AndreLopesAnd why does the neural network only accepts a DynamicObjectArray ?01:44
AndreLopesAnd also this.. SwigType_p_p_shogun_CSGObject01:44

@besser82lisitsyn, force pushed rebased commit into bugfix-branch13:28
@besser82lisitsyn, you should be able to resolve that by:  git checkout bugfix/apple_clang_check && git fetch --all && git reset --hard origin/bugfix/apple_clang_check13:29

sonne|worklisitsyn: around?16:19
@lisitsynsonne|work: yes16:21
sonne|worklisitsyn: I have a ML kind of problem - I have a few distributions (say 10)16:21
sonne|workand some mixture of these 10 distributions with unknown coefficients16:22
sonne|workI am now looking for a way to estimate the coefficients16:22
sonne|workand these given distributions are just based on counts - so histograms16:23
@lisitsynsonne|work: any assumption on distributions? :)16:24
sonne|worknone16:24
@lisitsynwhy not to fit GMM?16:25
sonne|workI could smooth them all :)16:25
sonne|workwell the base distribs are not gaussians16:25
@lisitsynthen choose something general and fit it with l-bfgs maybe?16:25
sonne|workor some gradient decent kind of thing ... hmmhh sure would work16:26
@lisitsynsonne|work: scipy has cool fmin_bfgs just give it a task16:27
sonne|worklisitsyn: yeah that would do it16:28
@lisitsynsonne|work: can you assume gamma distribution16:29
@lisitsyn?16:29
sonne|worklisitsyn: no the histograms can be anything even some multimodal stuff16:29
sonne|worklisitsyn: but that's good enough16:30
@lisitsynsonne|work: fitting multimodal mixture sounds scary :D16:30
sonne|worklisitsyn: relax all 1d - not so scary16:31
@lisitsynah16:31
@lisitsynwhy not to assume # of distributions equals # of modes?16:31
@lisitsynthen gaussian is good16:32
sonne|workall I know is that the resulting distribution is a mixture of the others - and I would 'just' want to know the most likely mixture coefficients16:35
sonne|workif the match is good enough then I can infer voila the distribution did get generated from the following sources16:35

@wikinglisitsyn: how do u use numpy array as a RealFeatures?21:17
@wikingbtw pytthon modular is totally broken still on osx21:17
@wikingsegfaults:<21:17
@lisitsynwiking: yeah I know21:17
@lisitsynRealFeatures(array)21:17

@wikinglisitsyn: here?22:10
@wikinglisitsyn: how the hell do u matplotlib a 2d numpy array, where each element is [a,b]. and the whole numpy array is like [[a,b],[x,v]...]22:11
@lisitsynwiking: hmm22:24
@lisitsynwiking: dont' get it22:24
@lisitsynyou need 2xN matrix?22:24
@wikingi just want to plot a 2d graph22:27
@wikingwhere the input is22:27
@wiking[[[a,b],[x,v]...]22:27
@wikingimean [[a,b],[x,v]...]22:28
@wikingbut if i do axis.plot(x...)22:28
@wikingthen i just get one part of each element of the arrays (the first) as y and x is basicaly the lenght of the array22:28
