mikelingWhy we need to make CBinaryLabels as {-1, 1} but CMultilabelLabels define as {0,1...num_classs-1}?07:24
mikelingI mean why we just define just define it as sort of 'DigitalLabels' which can accept {-1, 0, 1, ...num_classes}07:26
mikelingI'm wondering why we need CBinaryLabels as {-1, 1} rather than  {0, 1}07:28
mikelingso we could fix this issuehttps://github.com/shogun-toolbox/shogun/issues/3686 directly rather than cast one label to another07:28

mikelingHeikoS: hey!07:57
@HeikoShi07:57
@HeikoSall good?07:57
mikelingYep, nice to see you online :)07:58
@HeikoSyeah, I am travelling right now, so that was luck :)07:58
mikelingyou could tell me something about CBinaryLabels and CMultilabelLabels?07:58
@HeikoSI will be online more from the next few days07:58
@HeikoSsure07:58
mikelingI had notice this issue https://github.com/shogun-toolbox/shogun/issues/368607:59
mikelingWhy we need to make CBinaryLabels as {-1, 1} but CMultilabelLabels define as {0,1...num_classs-1}?07:59
mikelingcould we just define it as sort of 'DigitalLabels' which can accept {-1, 0, 1, ...num_classes}07:59
mikelingAnd could I cast CBinaryLabels to CMultilabelLabels?08:00
@HeikoSI think the distinction doesnt make sense08:01
@HeikoSI mean sure internally these representations are good08:01
@HeikoSbut from an API perspective they are nonsense08:01
@HeikoSthe algorithms should just check at runtine08:01
@HeikoSmikeling: I can talk more about this, but have to run now08:01
mikelingok, later :)08:01
@HeikoSsorry, but feel free to start an email thread on the list08:01
@HeikoSbecause I can reply to emails08:01
mikelingsure, thank you08:02

HeikoS_mobilemikeling: hi08:23
mikelingHeikoS_mobile: hi, I'm writing to email08:23
HeikoS_mobileSo I think there should be no distinction between label classes, just one class08:23
HeikoS_mobileAPI wise08:24
HeikoS_mobileInternally these classes offer ways to check whether the numbers stored do. make sense, and how to convert them to each other if possible08:24
HeikoS_mobilelisitsyn: thoughts?08:24
HeikoS_mobileBut to the outside user api, none of this should be visible08:25
HeikoS_mobileShould just take a bunch of numbers and them interpret them as labels in the desired way08:25
HeikoS_mobilewiking:08:25
HeikoS_mobileThis is also how the features api should look like inside the algorithms08:26
HeikoS_mobileBut start with labels08:26
HeikoS_mobilemikeling: you get what I mean?08:26
HeikoS_mobilemikeling: how's gsoc preparations going btw, all set for tomorrow? :)08:26
HeikoS_mobilercurtin: how do you manage all the projects you accepted?08:27
mikelingsorry, I'm writing the email. Yeah, everything going well I think08:27
HeikoS_mobileCool08:28
HeikoS_mobilemikeling: I think it's a good idea to refactor the labels08:28
HeikoS_mobileSo yeah you know my opinion now08:28
mikelingOk, Done08:29
HeikoS_mobileNice I'll check08:30
HeikoS_mobileSee you later08:30
mikelingThank you08:30
