| Guest88299 | Hello | 00:24 |
|---|---|---|
| Guest88299 | I'm trying to run shogun 2.0.0 with code and data that run fine under shogun 1.1.0 | 00:24 |
| Guest88299 | but I get this error:TypeError: Cannot create new instances of type 'Labels' | 00:25 |
| Guest88299 | I think this is the samep problem that is mentioned here:http://comments.gmane.org/gmane.comp.ai.machine-learning.shogun/2643 - but is unsolved | 00:25 |
| Guest88299 | any ideas? | 00:25 |
| shogun-buildbot | build #120 of nightly_default is complete: Failure [failed test] Build details are at http://www.shogun-toolbox.org/buildbot/builders/nightly_default/builds/120 | 03:43 |

| wiking | blackburn: yo | 16:19 |
| blackburn | wiking: hey | 16:19 |
| wiking | blackburn: u were looking for me | 16:19 |
| wiking | ? | 16:19 |
| blackburn | yeah | 16:20 |
| blackburn | these guys from company I am applying to want me to analyze https://imagecategorizer.services.open.xerox.com/ | 16:20 |
| blackburn | I'd appreciate if you share any thoughts :) | 16:20 |
| wiking | lol | 16:21 |
| wiking | they've opensourced it? | 16:21 |
| wiking | no | 16:21 |
| wiking | it's just the service | 16:21 |
| blackburn | heh right | 16:21 |
| blackburn | that makes the task a task | 16:22 |
| wiking | mmm | 16:22 |
| wiking | it's quite nice | 16:22 |
| wiking | have you tried to upload images? | 16:22 |
| blackburn | yes, quite a lot already | 16:22 |
| wiking | how is it? | 16:22 |
| wiking | btw: it's fun to upload dummy images :D | 16:23 |
| blackburn | well I put some blender images | 16:23 |
| blackburn | and smoothed/inverted/colored images, etc | 16:23 |
| wiking | i'm trying this http://412.laxallstars.com/files/2011/07/Brown.jpeg | 16:23 |
| wiking | but it says there's high traffic now | 16:24 |
| blackburn | I tried green plane | 16:24 |
| wiking | and? | 16:24 |
| blackburn | wanted it to think it is a grass | 16:24 |
| blackburn | :D | 16:24 |
| blackburn | no category at all | 16:24 |
| wiking | mmm that's good | 16:24 |
| blackburn | actually | 16:24 |
| blackburn | check ILSVRC 2011 | 16:24 |
| blackburn | these guys won it :) | 16:24 |
| blackburn | probably it is the same system | 16:25 |
| wiking | yeah i know their work | 16:25 |
| wiking | mostly based on fisher vector | 16:25 |
| wiking | right? | 16:25 |
| blackburn | yes | 16:25 |
| blackburn | product quantization | 16:25 |
| wiking | yep | 16:25 |
| blackburn | linear svm | 16:25 |
| blackburn | and fisher vectors | 16:25 |
| blackburn | SIFT + color histograms | 16:25 |
| wiking | yep yep | 16:25 |
| wiking | i know that one | 16:25 |
| blackburn | do you know how can I prove that it is a sift? | 16:26 |
| wiking | csurka is leading their group | 16:26 |
| wiking | mmm good question | 16:26 |
| blackburn | some computer vision hacking | 16:26 |
| blackburn | I was thinking about it | 16:26 |
| blackburn | but nothing except blurring | 16:26 |
| wiking | hehehe | 16:26 |
| wiking | well yeah u should trick sift | 16:26 |
| wiking | well what could be actually a funny thing to do | 16:27 |
| wiking | is to seed a random image | 16:27 |
| wiking | with some patches/sift keypoints of a chicken picture | 16:27 |
| wiking | :D | 16:27 |
| blackburn | I want to backtrace feature building | 16:27 |
| wiking | i bet that's possible | 16:27 |
| blackburn | hmm | 16:27 |
| blackburn | I thought of skating horse | 16:27 |
| wiking | and that the image u construct is still not a chicken :) | 16:27 |
| wiking | ehhehe | 16:27 |
| blackburn | I will do that tomorrow | 16:27 |
| blackburn | :D | 16:27 |
| blackburn | well but still | 16:28 |
| blackburn | I tried same thing actually | 16:28 |
| blackburn | yesterday I took a hockey player image | 16:28 |
| blackburn | and just 'cut' his legs | 16:28 |
| blackburn | 'skating' category disappeared | 16:28 |
| wiking | mmm | 16:29 |
| wiking | niice | 16:29 |
| blackburn | proves that it is a local feature thing | 16:29 |
| wiking | so you think puting the skaters on a horse | 16:29 |
| wiking | would do some trick :) | 16:29 |
| wiking | as said | 16:29 |
| blackburn | yeah horse on skates would make these guys laugh at least | 16:29 |
| wiking | :) | 16:29 |
| wiking | take a simple sift extractor | 16:29 |
| wiking | and get some patches | 16:30 |
| wiking | and randomly distribute that in a dummy image | 16:30 |
| blackburn | why do you think it proves the SIFTness? | 16:30 |
| wiking | and then maybe get 2 sets of differetn sift features (from 2 different image categories) and start randomly mixing them in a new dummy image | 16:31 |
| blackburn | I am thinking about something very special about SIFT | 16:31 |
| blackburn | blurring is one thing - gradients go worse with it | 16:31 |
| wiking | well | 16:31 |
| wiking | one good thing is an affine transform of the image | 16:32 |
| wiking | to check what type of sift they are using | 16:32 |
| wiking | the default sift implementation is not so good with affine transformation | 16:32 |
| blackburn | hmm right right | 16:32 |
| blackburn | rotations is what I didn't try yet | 16:32 |
| blackburn | good idea | 16:32 |
| wiking | well not only rotate | 16:33 |
| blackburn | yeah | 16:33 |
| wiking | but like rotate and make a trapezoid of the original image | 16:33 |
| wiking | for example with the eiffel tower | 16:33 |
| blackburn | well I'll try some fisheye | 16:33 |
| wiking | yeah | 16:33 |
| blackburn | to see whether it is robust | 16:33 |
| blackburn | wiking: do you understand what is a way to handle multiple patches but within the same dimension of feature space? | 16:51 |
| blackburn | that's the thing I miss | 16:51 |
| wiking | blackburn: eh? | 16:53 |
| wiking | blackburn: i guess they could use some pca | 16:53 |
| wiking | as they usually do in their system at xerox | 16:53 |
| blackburn | I mean if one image has 3 patches | 16:54 |
| blackburn | and other has 9 | 16:54 |
| blackburn | how pca could help there? | 16:54 |
| wiking | well they don't give a damnfuck about the number of patches | 16:54 |
| wiking | as they calculate in a way a frequency vector | 16:54 |
| wiking | of the patches | 16:54 |
| wiking | of the number of various patches | 16:55 |
| blackburn | ahhh | 16:55 |
| wiking | that is then normalised | 16:55 |
| wiking | so that's your feature vector, i.e. the fisher vector | 16:55 |
| wiking | in the case of xerox | 16:55 |
| blackburn | so # of features is just ~ to # of possible visual words? | 16:55 |
| wiking | yep yep | 16:55 |
| wiking | usual drill | 16:55 |
| blackburn | got it | 16:55 |
| wiking | the fisher vector is something like a bag of visual words | 16:55 |
| wiking | a bit more scientific | 16:55 |
| wiking | but on the end it is basically doing that | 16:56 |
| blackburn | cool | 16:56 |
| blackburn | more clear now | 16:56 |
| wiking | heheh welcome :) | 16:56 |
| blackburn | thanks | 16:56 |
| wiking | hack the shit out of their system :)) | 16:56 |
| wiking | if i'd have time i'd really help | 16:56 |
| blackburn | yeah, I should try to hack out sift | 16:56 |
| wiking | because this way you could prove some funky security stuff | 16:56 |
| blackburn | no problem you helped a lot already | 16:56 |
| wiking | or let say | 16:56 |
| wiking | how to SEO and image search engine :P | 16:57 |
| blackburn | yeah | 16:57 |
| wiking | afaik this has been not really exploited yet | 16:57 |
| wiking | but for sure it can be | 16:57 |
| wiking | as all the keypoint extractors | 16:57 |
| wiking | are very very | 16:57 |
| wiking | academic | 16:57 |
| wiking | so they must have several flaws | 16:57 |
| wiking | :) | 16:57 |

| wiking | RebeccaTruty: where? | 21:34 |
| RebeccaTruty | oh sorry, here: http://pastebin.com/FczYqj40 | 21:39 |
| wiking | RebeccaTruty: oh yeah | 21:39 |
| wiking | the thing is that Labels class has been majorly redesign | 21:39 |
| wiking | so you'll have to change your code | 21:39 |
| RebeccaTruty | I see | 21:39 |
| wiking | so in this case | 21:40 |
| wiking | use DenseLabels | 21:40 |
| wiking | wait | 21:40 |
| wiking | random.choice([0.0, 1.0]) | 21:40 |
| wiking | gives you 0 or 1 or a random number in [0,1] interval? | 21:40 |
| RebeccaTruty | it give you a 1 or 0 | 21:40 |
| wiking | ah ok | 21:41 |
| wiking | then just use | 21:41 |
| wiking | BinaryLabels | 21:41 |
| RebeccaTruty | great, thanks | 21:41 |
| wiking | http://www.shogun-toolbox.org/doc/en/current/classshogun_1_1CBinaryLabels.html | 21:41 |
| wiking | that's the doxygen for the class | 21:41 |
| wiking | but yeah it shoudl work | 21:42 |
| wiking | if you just replace | 21:42 |
| wiking | test_labels = Labels(np.array(raw_labels, dtype=np.double)) | 21:42 |
| wiking | to | 21:42 |
| RebeccaTruty | yup, thanks, sorry I didn't realize it was such a stupid question - I shoudl have looked into it more | 21:42 |
| wiking | test_labels = BinaryLabels(np.array(raw_labels, dtype=np.double)) | 21:42 |
| wiking | RebeccaTruty: na no worries | 21:42 |
| wiking | we just needed a bit more complex labeling system... :P | 21:42 |
| RebeccaTruty | understood. thanks for the help! | 21:42 |
| wiking | no worries | 21:43 |
| wiking | but next time i think you'd get a faster answer on the mailinglist of shogun | 21:43 |
| wiking | mmm fuck where's the link on the new website to the mailing list :) | 21:44 |
| wiking | sonney2k blackburn where's the mailing list information on the new website? | 21:44 |
| wiking | ah ok i've found it | 21:45 |
| wiking | http://www.shogun-toolbox.org/page/contact/others | 21:45 |
| blackburn | uh you were having kinda discussion | 21:45 |
| wiking | blackburn: ehhehe no worries forget that i was messaging :P | 21:45 |
| blackburn | somebody asked about labels thing yesterday | 21:46 |
| blackburn | was that you, RebeccaTruty | 21:46 |
| blackburn | ? | 21:46 |
| RebeccaTruty | yes - that was me | 21:46 |
| blackburn | clear, I am sorry you've got to handle this transformation manually | 21:46 |
| blackburn | we came to case where we had no other solution because of design gap | 21:47 |
| RebeccaTruty | yeah, no problem, it should be an easy enough fix. | 21:48 |

| blackburn | my city is not highlighted, is that good? :) | 22:14 |
| blackburn | ahhh who stars his project | 22:14 |
| blackburn | wiking: find me! | 22:15 |
| blackburn | there are only 5 in russia | 22:15 |
