yoohi there11:00
yooafter adding (with blackburn)  ms_output->output_custom_evaluations(result_labels, m_labels) in crossvalidation->evaluate_one_run()  line 220, I add the same line 302 for machine with data unlocked (most machines I use) and I get a seg fault when calling m_custom_evaluations->get_num_elements()11:03
yoocould someone explain me why ?11:03

thegruelHi all15:02
thegruelIs there a ModelSelection expert in the house?15:07
-!- pluskid [~pluskid@] has quit [Quit: Leaving]15:13
thegruelAnyway... I was wondering if there is a model selection strategy in Shogun that allows selecting C1/C2 for libSVM but avoids the full grid search, ideally by enforcing C1=C2.15:14

blackburnyoo: oops15:58
blackburnI just forgot to initialize it :D16:01
CIA-18shogun: Sergey Lisitsyn master * r57d6371 / (2 files in 2 dirs): Added missed initialization of custom evaluations array -

yooblackburn: hi18:04
blackburnyoo: hi18:04
yooblackburn: I ve seen your fix but didnt solve the pb on my machine18:04
blackburnyoo: still segfault?18:04
yooblackburn: yep, I am trying to reproduce the pb with simple shogun example18:05
yoogive me a minute18:05
blackburnwould be nice18:05
yoodo you have the link I gave you last night ?18:06
-!- puffin444 [62e3926e@gateway/web/freenode/ip.] has joined #shogun18:06
yooblackburn: ok this one : change the inputs and add msoutput as well =)18:07
blackburnokay give me a minute18:07
blackburnyoo: so what exactly faults?18:08
blackburnadding a custom evaluation to output?18:08
yooblackburn: CModelSelectionOutput *ms_output = new CModelSelectionOutput(); how adding a custom eval to this obj ?18:10
blackburnyoo: well actually it works here with latest git18:11
blackburnyoo: ms_output->add_evaluation(new CMulticlassAccuracy()) will output you a confusion matrix on each split18:12
yooblackburn: ok sorry my bad, I didnt go throw your new add_custom function18:12
yooblackburn: works perfectly18:12
yooblackburn: btw what the best method if I want to store those matrices into files, is there interaction possible between msoutput and any filestorage obect  ?18:14
blackburnyoo: yeah I thought of it18:15
blackburnI can do that18:15
yooblackburn: the object msoutput dont store anythg right ? it just print the matrices ?18:15
blackburnyoo: I will just add output to ostream18:16
yoosure but then evrythg ll be printed, mb it should be smthg like the msoutput store data and then interact with what ever we need ?18:17
yoothen we can draw smthg, compare different confusion matrices .. etc .. without parsing a file with every outputs ..18:18
blackburnyoo: hmm okay I will do that this way then18:18
blackburnI don't mind any18:18
yooIt is mb more the way msoutput is designed for since your passng the obj in argument .. dunno :p18:19
yoothanks again for this great support !18:19

blackburnalexlovesdata: I failed to :(19:43
blackburnfor vodka pong19:43
alexlovesdataye, in Russia competition for that discipline is indeed hard and your liver might not be fresh anymore19:46
blackburnbeing professional is a hard job19:47
alexlovesdataunfortunately unreadable code which still works is not accepted yet19:47
alexlovesdataotherwise I oculd have tried19:47
alexlovesdatano there was a mail by Carol Smith from google rumoring about that ... so the question has a grain of truth19:48
blackburnchances are it goes to the special olympics program19:49
blackburnvery special :D19:49

droopyn4nd0, ;)22:11
n4nd0I am sure you will find a good approach22:11
blackburnheh thanks22:11
blackburnn4nd0: did you ever actually use that xval and model selection stuff?22:12
n4nd0blackburn: no!22:17
n4nd0but I think I must look into it22:17
blackburnn4nd0: yeah at some point22:17
n4nd0I know the concepts but I think I have never used them "for real"22:18
