Ram108 | hi anybody there? | 18:11 |
blackburn1 | Ram108: yeah, I'm here | 18:11 |
Ram108 | hi i have some queries | 18:11 |
Ram108 | could u clear them out please | 18:11 |
blackburn1 | sure, shoot | 18:11 |
Ram108 | firstly i have recently started with machine learning | 18:11 |
Ram108 | and i have googled up some tool boxes and found urs to be good | 18:12 |
blackburn1 | ok, you told it to us day before ;) | 18:12 |
Ram108 | but couldnt quite figure out were to start learning | 18:12 |
Ram108 | yeah but i didnt get any response lol :P | 18:12 |
Ram108 | am sort of desperate to learn it | 18:13 |
Ram108 | lol :P | 18:13 |
blackburn1 | Ram108: well you could start with trying various methods | 18:13 |
Ram108 | and i really want to contribute in whatever little way i can to shogun | 18:13 |
Ram108 | methods as in? | 18:13 |
blackburn1 | well e.g. with given data you could try different methods of classification | 18:14 |
-!- ishaan_ [~chatzilla@14.98.156.214] has joined #shogun | 18:14 | |
blackburn1 | or clustering, or regression | 18:14 |
Ram108 | like MLP RBF etc etc yeah sure | 18:14 |
Ram108 | i ll try them :) | 18:15 |
Ram108 | and i noticed shogun does not contain MLP | 18:15 |
Ram108 | would it be useful if i were to implement them? | 18:15 |
blackburn1 | Ram108: sorry what is MLP? | 18:15 |

-!- ishaan_ is now known as ishaan | 18:16 | |
Ram108 | sorry | 18:16 |
blackburn1 | hmm sure feel free to impelement it | 18:16 |
Ram108 | thanks :) well can i email it to you? after i implement it? | 18:16 |
blackburn1 | Ram108: we don't have much neural methods, it is welcome for sure | 18:16 |
Ram108 | oh thats great news..... i just finished a course on neural networks :) | 18:17 |
blackburn1 | Ram108: I would suggest you to ask me about any shogun related questions | 18:17 |
Ram108 | okay sure ..... i tried downloading shogun and import sg in python did not work | 18:18 |
blackburn1 | Ram108: hmm ok then lets start from installing it firstly ;) | 18:18 |
blackburn1 | did you use git? | 18:18 |
Ram108 | i tried googling it up as well..... sure :) | 18:18 |
Ram108 | yeah :) | 18:18 |
Ram108 | i did use git :) | 18:19 |
blackburn1 | wait, import sg? | 18:19 |
blackburn1 | you should use import modshogun | 18:19 |
Ram108 | well the example on the website had import sg | 18:19 |
blackburn1 | hmm we should fix it ;) | 18:19 |
Ram108 | :) | 18:19 |
Ram108 | thank you :) | 18:20 |
blackburn1 | Ram108: check examples/undocumented/python_modular | 18:20 |
blackburn1 | in your clone | 18:20 |
blackburn1 | btw try to run any classifier_* example | 18:20 |
Ram108 | oh okay i ll get back to you once i try that :) | 18:20 |
Ram108 | sure thank you :) | 18:20 |
blackburn1 | okay, don't hesitate to ask anything | 18:20 |
blackburn1 | I like receiving emails lol :) | 18:21 |
Ram108 | thank you for ur time :) greatly appreciate it :) | 18:21 |
Ram108 | lol :) do u mind i know who you are? | 18:21 |
Ram108 | i am Ram :) | 18:21 |
blackburn1 | Ram108: my name is Sergey Lisitsyn, I'm a gsoc 2011 student of shogun that became a core developer | 18:22 |
Ram108 | cool :P i have read about u implementing Vowpal wabbit | 18:23 |
Ram108 | thats awesome :) | 18:23 |
blackburn1 | no | 18:23 |
blackburn1 | that wasn't me ;) | 18:23 |
Ram108 | oh am sorry | 18:23 |
blackburn1 | not a problem ;) | 18:23 |
Ram108 | :) | 18:23 |
blackburn1 | I have implemented a lot of dimension reduction stuff | 18:23 |
Ram108 | nice :) | 18:23 |
blackburn1 | but I still do some development of these methods | 18:24 |
Ram108 | i am having dependency issues i ll resolve them and get back to u :) | 18:24 |
Ram108 | if you dont mind can i have ur email id pls? | 18:24 |

Ram108 | thank you a lot :) | 18:25 |
blackburn1 | Ram108: what are the dependencies you have to resolve? | 18:25 |
blackburn1 | btw, what is the os you are using? | 18:25 |
Ram108 | ubuntu distro maverick meerkat.... 10.10 | 18:26 |
blackburn1 | oh nice, you won't have any problems | 18:26 |
Ram108 | thank you :) | 18:26 |
blackburn1 | I'm using 10.04 and sonney2k is using debian (he is a debian developer) | 18:27 |
Ram108 | oh nice :) | 18:27 |
Ram108 | No module named shogun.Features | 18:28 |
Ram108 | thats the error i keep getting | 18:28 |
Ram108 | :( lol | 18:28 |
Ram108 | is it that i didnt install shogun properly? | 18:28 |
blackburn1 | Ram108: how did you install it? | 18:28 |
Ram108 | well i installed the dependencies using apt-get package manager as well as synaptic | 18:29 |
Ram108 | then downloaded shogun frm git via the terminal | 18:29 |
Ram108 | thats it | 18:30 |
Ram108 | do i have to do anythn else? | 18:30 |
blackburn1 | Ram108: sure, you should run 'configure --interfaces=python_modular' in src/ of shogun | 18:30 |
blackburn1 | then make | 18:31 |
blackburn1 | and sudo make install | 18:31 |
Ram108 | Mr soeren does not seem active here | 18:31 |
Ram108 | yeah i did that | 18:31 |
blackburn1 | he is pretty busy | 18:31 |
Ram108 | but not the configure thinge | 18:31 |
blackburn1 | much more than me | 18:31 |
Ram108 | oh hmmm :) | 18:31 |
Ram108 | initially i did./configure... then sudo make....... then sudo make install | 18:32 |
blackburn1 | almost right | 18:32 |
blackburn1 | but --interfaces=python_modular | 18:32 |
blackburn1 | in configure params | 18:33 |
blackburn1 | to compile with python modular interface support | 18:33 |
Ram108 | oh hmmm i ll purge it then reinstall it | 18:33 |
Ram108 | hope it wont affect the dependencies | 18:33 |
-!- puneetgoyal [~chatzilla@115.242.19.18] has joined #shogun | 18:34 | |
Ram108 | yeah am on it again...... ./configure --interfaces=python_modular | 18:34 |
blackburn1 | make sure configure went smooth | 18:35 |
Ram108 | the final line is "Result is no" | 18:35 |
blackburn1 | hmm | 18:35 |
blackburn1 | what is last Checking for X .. no? | 18:36 |
blackburn1 | I guess Python numpy developer files? | 18:36 |
Ram108 | nope the same error again | 18:36 |
Ram108 | i have numpy | 18:36 |
Ram108 | i have used it previously | 18:36 |
blackburn1 | dev? | 18:36 |
blackburn1 | get sure you have python-numpy-dev package installed | 18:37 |
Ram108 | yeah i guess numpy is the issue | 18:37 |
Ram108 | oh thanks i ll install it off synaptic now | 18:37 |
Ram108 | i dont think there is numpy-dev | 18:38 |
Ram108 | there is just numpy and numpy-dbg | 18:39 |

blackburn1 | Ram108: swig has to have headers to compile interface | 18:42 |
Ram108 | am sorry i dont understand | 18:43 |
Ram108 | both the package managers dont have python-numpy-dev | 18:44 |
blackburn1 | I meant numpy-dev is headers of numpy | 18:44 |
blackburn1 | ehmm | 18:44 |
blackburn1 | ahh | 18:44 |
Ram108 | oh am sorry i ll google that up | 18:44 |
blackburn1 | can't be | 18:44 |
-!- blackburn1 is now known as blackburn | 18:44 | |
blackburn | I have one in 10.04 :) | 18:44 |
Ram108 | gosh..... i ll try procuring them..... thanks | 18:45 |
blackburn | how can it be? | 18:47 |
Ram108 | i ll send u a screen shot of the list i have | 18:47 |
blackburn | Ram108: try to 'sudo apt-get install python-numpy-dev' | 18:49 |
Ram108 | already tried | 18:49 |
Ram108 | terminal says try python-numpy instead | 18:50 |
Ram108 | and wen i try that "all packages upto date" | 18:50 |
blackburn | ehmm may be you have some untypical sources for packages? | 18:50 |
Ram108 | oh god!!! lol :P i ll try downloading the .tar file for that | 18:51 |
blackburn | Ram108: noo | 18:51 |
blackburn | I got wrong sorry | 18:51 |
Ram108 | oh erm? | 18:52 |
blackburn | python-dev | 18:52 |
blackburn | orr | 18:52 |
blackburn | yes | 18:52 |
blackburn | python-dev | 18:52 |
blackburn | not numpy dev, sorry | 18:52 |
Ram108 | oh lol :P | 18:52 |
Ram108 | oh god thats a big file :P 18 mins left lol | 18:54 |
Ram108 | why isnt the classifiers of shogun well completed? i mean on the web page it says so | 19:02 |
Ram108 | that prompted me to implement MLPs | 19:02 |
blackburn | Ram108: what do you mean? | 19:05 |
Ram108 | i meant classifiers like multilayered perceptrons and radial basis functions were not used much(neural networks) any specific reason for that? | 19:07 |
blackburn | do you ask why we have no MLP and etc? | 19:08 |
Ram108 | yeah? | 19:08 |
blackburn | well we have a lot of svms ;) | 19:08 |
Ram108 | cool :) | 19:08 |
blackburn | as shogun was developed for some bioinformatics tasks SVMs were more important | 19:09 |
Ram108 | and the 7 methods you implemented can reduce any n dimensional vector set to 3 or 2 dimensional vector sets right? | 19:09 |
Ram108 | oh hmmm :) | 19:09 |
blackburn | Ram108: yes | 19:09 |
Ram108 | awesome :) | 19:10 |
blackburn | not a vector but a set of vectors | 19:10 |
Ram108 | thanks a lot :) i feel humbled lol :P | 19:10 |
Ram108 | oh thanks :) | 19:10 |
Ram108 | finally installing..... | 19:10 |

Ram108 | sheesh..... thats amazing..... | 19:12 |
Ram108 | is the facial expression thinge fast? | 19:12 |
Ram108 | how long did it take? | 19:13 |
Ram108 | god! the same error again :( | 19:13 |
blackburn | Ram108: 1-2s | 19:14 |
Ram108 | python3-all-dev and python2.6-dev installed | 19:14 |
Ram108 | okay :) | 19:14 |
blackburn | did you configure with python modular enabled? | 19:15 |
Ram108 | no i used synaptic package manager.... how do i do that? | 19:15 |
blackburn | ./configure --interfaces=python_modular? | 19:18 |
Ram108 | yeah i ll do that again | 19:18 |
Ram108 | yeah :) :D :P i think this time i can see some magic :) | 19:19 |
Ram108 | finally its working :) | 19:27 |
Ram108 | big time thanks :) | 19:27 |
Ram108 | thank you so much for your time Mr.Lisitsyn | 19:28 |
Ram108 | i ll work through them and learn them | 19:28 |

@sonney2k | puneetgoyal, just use e.g. libsvm for starters | 21:54 |

rrenaud | does anyone use shogun for online learning? i am reading some of the code for the VW wrapper, and it seems to require using file i/o, which seems kind of annoying | 22:43 |
@sonney2k | rrenaud, how else could you do online learning? | 22:45 |
rrenaud | i generate feature vectors in memory, send them to the system, get predictions (maybe with labels), and it maybe updates its model if i gave labels | 22:46 |
@sonney2k | I see - I suggest to ask shashwat about that (cc'ing me) | 22:48 |
