Ram108hi..... thr?08:55
sonne|workGood morning...09:33
Ram108hi mr sonnenburg09:34
Ram108Mr Lisitsyn helped me to set up some classifiers but i could not get it to work09:36
Ram108i was wondering if either of u could aid me a little more09:36
sonne|workplease be more specific - just directly ask the question10:02
blackburnRam108: how can I help you?10:29
Ram108sorry for the delay10:37
Ram108well i have created the RealFeatures and Labels and KNN requires  train and test vector sets..... how do i generate them from the dataset10:39
Ram108http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data is the data set he asked me to classify10:40

Ram108hi14:41
Ram108Mr. Lisitsyn can u help me out with the rest of the implementation14:42
blackburnyes, but call me more informal, I'm too young to be mr :D14:46
Ram108lo, :) okay sure :)14:46
blackburnhow can i help you?14:47
Ram108well i have created the RealFeatures and Labels. KNN requires  train and test vector sets14:47
Ram108are test and train vectors created by handpicking some out of the data set14:48
blackburnyes14:48
blackburnso?14:48
blackburnah, it is a question? :)14:49
Ram108so shill i create that...... and then use KNN14:49
Ram108?14:49
blackburnyes, you have to create RealFeatures and Labels for train vectors and RealFeatures for test vectors14:49
blackburnexample:14:50
blackburn[1,2,3] label 014:50
blackburn[3,4,5] label 014:50
blackburn[9,8,7] label 114:50
blackburnand test set14:51
blackburn[0,1,2]14:51
blackburn[7,8,6]14:51
Ram108oh hmmm14:51
blackburnfeature matrix for train set is14:51
blackburn[[1,3,9],14:51
blackburn [2,4,8]14:51
blackburn [3,5,7]]14:51
blackburnthen labels are [0,0,1]14:51
blackburnsame for test set14:51
blackburnit should be done in this fashion14:52
Ram108hmmm :)14:52
Ram108thanks :)14:52
blackburnthen after applying you will get probably [0,1] for this data14:52
Ram108oh hmmm14:53
blackburnafter that you can compare labels that you've got with classifier and 'ground truth' labels14:53
Ram108well i have created Real features bu calling the RealFeatures() and labels by invoking the Label() method14:55
blackburnand?14:55
Ram108and now i ll have to create a seperate test and train set by spooling a few samples and making then into the form vector1=[5.0,3.4,1.5,0.2] and label 0 for Iris-setosa14:57
Ram108likewise for all the other test and train examples14:58
blackburnseparate it before creating RealFeatures14:59
Ram108[[vec1],[vec2],[vec3]......] and labels [ 0, 0, 1, 1, 2, 2.... ]15:00
Ram108yeah i think i got it15:00
blackburnok15:00
Ram108i ll code it to u and email u the file15:00
blackburnokay15:00
Ram108its just a simple modification to the old file i sent yesterday right?15:01
blackburnsomething like that15:01
Ram108hmmm :)15:01
Ram108thanks a lot..... am i bugging u?15:01
Ram108sorry if i am....15:01

puneetgoyalhello :) can you please tell RealFeatures function?15:05
Ram108hi puneet15:06
puneetgoyalwhat all datatype are handled in RealFeatures function?15:06
puneetgoyalhello Ram :)15:06
Ram108heard u r another guy wanting to learn this toolbox out15:07
Ram108:P15:07
puneetgoyalyeah...I guess you have already done this...can you please help me out with this15:08
Ram108well all i did was....15:09
Ram108can i email u my code?15:09
Ram108do u have skype or sumthn?15:09
puneetgoyalcheck out the other window15:10
-!- Ram108 [~amma@14.96.211.205] has quit [Ping timeout: 248 seconds]15:14
blackburnRealFeatures is not a function, it is a class15:14
puneetgoyalyeah..I mean to ask what arguments does it take? blackburn ?15:18
blackburnpuneetgoyal: numpy matrix15:18
puneetgoyalI have seen the class...it says some dotfeatures15:18
blackburnRealFeatures is a SimpleFeatures<float64_t>15:19
blackburnand SimpleFeatures is inherited from DotFeatures15:19
puneetgoyalok...but float64 is only for floating variable right? so how do we let it work for strings?15:20
blackburnStringFeatures15:22
puneetgoyalbut it says StringFeatures is not defined...do I have to import some another file for this?15:23
sonne|workStringCharFeatures ...15:23
puneetgoyalok..thank you :)15:28
puneetgoyaland while creating a numpy matrix again we have to define a datatype...what if we have both float and character variables inside the data? we can use the object datatype..but I guess there is no class for it to convert it into feature matrix15:29
-!- Ram108 [~amma@14.99.111.107] has joined #shogun15:31
sonne|workpuneetgoyal: create realfeatures for the float stuff and stringcharfeatures for the string stuff15:34

Ram108call me ram16:55
puneetgoyaloh thats just to give you a notification16:55
Ram108:)16:55
Ram108well do u want me to email u my code?16:55
Ram108its pretty shoddy though16:56
puneetgoyalthanks... I figured it out...there was a silly error in my data file :P16:56
Ram108hmmm did u figure out the whole classification thinge?16:56
Ram108i havent reached till that yet16:57
Ram108having trouble16:57
puneetgoyalI just needed the realfeature matrix to get going for svm classification for now16:57
Ram108well? could u help me out with that?16:57
puneetgoyalyeah..sure...tell me16:58
Ram108well i guess i formed the RealFeature matrix and label16:58
Ram108and now i am supposed to generate test and train vectors16:58
Ram108well do u have an example for that?16:59
puneetgoyalok and what's the problem?16:59
Ram108well i am nt really clear hw that shld look like17:00
Ram108if i had an example i could follow it easily :)17:00
puneetgoyalhave you seen the undocumented examples?17:01

Ram108yeah but i really want to classify http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data17:02
puneetgoyalusing what classifier?17:06
puneetgoyalwhich classifier?17:06
Ram108KNN17:07
puneetgoyalthere is an example classifier_knn17:08
Ram108yeah k thanks17:08
puneetgoyaljust replace your matrix with its matrix17:08
Ram108k thanks :)17:08
Ram108were did u exactly find it?17:09

puneetgoyalhey ....can I have these data files... fm_train_real.dat, fm_test_real.dat and label_train_twoclass.dat20:30
blackburngit submodule update20:37
@sonney2kgit submodule update --init20:46
blackburnsecond is better hehe20:48
blackburnsonney2k: will you have a chance to pack a .deb?20:49

@sonney2kblackburn, mind preparing release notes that you can send out to the shogun mailinglist when I give you the go21:31
@sonney2k?21:31
blackburnsonney2k: you mean some announcement on release of 1.1.0?21:31
@sonney2kyes21:31
blackburnwell I could21:32
@sonney2kjust copy what is on the website/ what I posted and add some brief summary - I guess this time it is mostly compile fixes, speedup compilation + your preproc/converter stuff21:32
blackburnwebsite?21:33
blackburnwhat did you posted?21:33
@sonney2kcheck the 1.0.0 announcement on the mailinglist21:35
blackburnhmm ok21:35

blackburnsonney2k: should I send it?21:54
@sonney2knot yet21:55
@sonney2kblackburn, can you please have a look at the .tar.bz2 I generated?22:14
@sonney2kI had to redo it manually...22:14
@sonney2kseems like my release script still has a bug22:14
blackburnsonney2k: hmm sure, where can I find it?22:14
@sonney2kblackburn, http://www.shogun-toolbox.org :-)22:14
blackburnsonney2k: have you had experience of linking shogun and MKL?22:16
@sonney2kI have no time for that now22:16
blackburnI tried this morning and failed :)22:17
@sonney2klets get the release out and then I have to sleep ASAP22:17
blackburnheh sure, I'm just asked whether you had22:17
@sonney2khave to get up in ~5 hrs22:17
@sonney2kflying to granada / nips tomorrow22:17
blackburnwow22:17

blackburnsonney2k: ^22:19
@sonney2kblackburn, well did you run configure??22:20
blackburnI'm not an idiot yet :D22:21
blackburndoes it compile smoothly on your machine?22:22

blackburnsonney2k: do you know the problem?22:26
@sonney2kno I don't understand what is going on22:27
blackburnI faced this error before but do not know how to solve it22:27
blackburnwhat is .depend?22:28
blackburnsonney2k: btw make called in / leads to 'fatal: Not a git repository (or any of the parent directories): .git'22:32
@sonney2kwhy didn't you tell me?22:32
blackburnsonney2k: did not tell what?22:32
@sonney2kthat you have seen this error at some point22:32

alesis-noviksonney2k, I was too distracted and forgot to reply to your e-mail23:07
alesis-novikI use the vector in GMM just for storing separate Gaussians, not as a mathematical concept(?)23:07
alesis-novikWas that what you were asking?23:08
@sonney2kalesis-novik, I was asking if you could change it to Dynarray or so23:09
shogun-buildbotbuild #384 of r_static is complete: Failure [failed test test_1]  Build details are at http://www.shogun-toolbox.org/buildbot/builders/r_static/builds/384  blamelist: sonne@debian.org23:09
alesis-novikCongratulations on getting 1.1.0 out guys!23:09
@sonney2kalesis-novik, because I want to make vector a mathematical thing like v+u = w23:09
@sonney2kwhich won't work with your gaussians23:09
alesis-noviksonney2k, well, you can technically add Gaussians, though it wouldn't make any sense in this context23:10
alesis-noviksonney2k, so is that still an open problem?23:11
@sonney2kyes so please convert it then to Dynamic / Dynarray23:11
@sonney2kyes23:11
alesis-novikI have some time now since it's close to Christmas and research has slowed down23:11
alesis-noviksonney2k, I'll do it over the next few days then23:12
@sonney2kgreat!23:12
@sonney2kthen I can continue my SGVector effort :)23:12
alesis-novikI'd like to have more time to work on Shogun, but lately I've been working on my own topic, so not really enough time :/23:13
