| wiking | this is funny | 00:02 |
|---|---|---|
| wiking | n4nd0: i've just found 3 different papers with 3 different author sets on 3 different publication years talking about essentially the same | 00:02 |
| n4nd0 | nice! | 00:03 |
| n4nd0 | what about? | 00:03 |
| wiking | n4nd0: apparently i've found the solution for this approx | 00:17 |
| wiking | indeed | 00:18 |
| n4nd0 | cool | 00:18 |
| n4nd0 | what is it? | 00:18 |
| wiking | 1/\beta \log \sum exp(\beta * f(x,y,w)) | 00:18 |
| wiking | lim \beta -> \inf | 00:18 |
| wiking | will result in | 00:18 |
| wiking | max (f(x,y,w)) | 00:19 |
| wiking | i mean | 00:19 |
| wiking | i've missed \delta(y,y_i) | 00:19 |
| wiking | but you know what i mena | 00:19 |
| wiking | mean | 00:19 |
| n4nd0 | yeah I kind of get the idea | 00:19 |
| n4nd0 | I don't know right now if that is the true answer for the limit | 00:19 |
| n4nd0 | but I believe you :) | 00:19 |
| wiking | well in the paper they even have a proof for it | 00:20 |
| wiking | so yeah i trust them as well | 00:20 |
| wiking | actually i've read it | 00:21 |
| wiking | it makes sense | 00:21 |
| wiking | so anyhow | 00:21 |
| wiking | we could add a softmax thing for so learning | 00:21 |
| n4nd0 | for the so-svm? | 00:22 |
| wiking | yes | 00:22 |
| n4nd0 | ok | 00:22 |
| n4nd0 | do you get something similar to a CRF then? | 00:22 |
| wiking | yes | 00:23 |
| wiking | \beta = 0 CRF | 00:23 |
| wiking | \beta = inf SSVM | 00:23 |
| n4nd0 | interesting | 00:23 |
| wiking | and it's super easy to implement this with BMRM | 00:24 |
| wiking | n4nd0: Entropy and Margin Maximization for Structured Output Learning | 00:25 |
| wiking | check this paper | 00:25 |
| wiking | mmm | 00:36 |
| wiking | this paper is cool | 00:36 |
| wiking | i've just realised that we can do MIL with latent framework :) | 00:36 |
| n4nd0 | what's MIL? | 00:37 |
| wiking | multiple instance learning | 00:37 |
| wiking | so you get n set of (x_1,...,x_n) | 00:38 |
| wiking | and u know that each set has a label y | 00:38 |
| n4nd0 | haha it seems that new types of learning don't stop popping out | 00:38 |
| wiking | but you don't know the exact label for each x_i | 00:38 |
| wiking | and of course it could be that you get a set of x-es | 00:39 |
| wiking | with label y_i | 00:39 |
| wiking | but that some of those x-es are not really y_i | 00:39 |
| wiking | We construct a one-dimensional synthetic dataset which illustrates the de- ficiencies of the MI-SVM. A positive bag consists of p positive instances and 50 - p negative (0 < p <= 50), a negative bag contains 50 negative instances. The individual instances are hard to classify: the positive instances are Gaussian dis- tributed with mean 0.6 whereas the negative instances are Gaussian distributed with mean 0, the variance for both classes is 1. | 00:40 |
| wiking | this is what they do | 00:40 |
| n4nd0 | aham it sounds cool | 00:41 |
| n4nd0 | a way to get rid of data outliers maybe | 00:41 |
| wiking | let see if i can do this | 00:42 |
| wiking | should be easy to generate this dataset :) | 00:42 |
| n4nd0 | yeah | 00:42 |
| n4nd0 | time to sleep | 00:53 |

| wiking | yes | 10:34 |

| wiking | ok i thnk i have an awesome example coming up for shogun | 10:52 |
| wiking | it's even graphical | 10:52 |
| wiking | so you can post it to the webpage | 10:52 |
| blackburn | does it contain tits? | 10:53 |
| wiking | blackburn: :D | 10:54 |
| wiking | sonne|work: mmm i think there's a way to connect buildbots as well to the pull request hook in github | 10:54 |
| sonne|work | wiking: ? | 10:55 |
| wiking | sonne|work: well i've just seen this | 10:55 |
| sonne|work | it is | 10:55 |
| wiking | sonne|work: https://github.com/Itseez/opencv/pull/181 | 10:55 |
| sonne|work | ahh | 10:55 |
| sonne|work | ok so you mean even before commit | 10:55 |
| wiking | sonne|work: and that link there for good to merge | 10:55 |
| wiking | is not coming from travis | 10:55 |
| wiking | it's from a buildbot | 10:55 |
| wiking | sonne|work: indeed, so it's like travis | 10:56 |
| wiking | sonne|work: ah ok i think i know how it works | 10:58 |
| wiking | sonne|work: you need to define in service hooks | 10:58 |
| wiking | a webhook url | 10:58 |
| wiking | as it says | 10:58 |
| wiking | "We'll hit these URLs with POST requests when you push to us, passing along information about the push. More information can be found in the Post-Receive Guide." | 10:58 |

| @sonney2k | wiking, I finally understand why the buildbot is failing on cygwin | 22:04 |
| @sonney2k | we use a reserved word | 22:04 |
| @sonney2k | __from! nothing should be __'t | 22:05 |
| wiking | ?? | 22:07 |
| wiking | lolface | 22:07 |
| wiking | yeah that's uricamic's coe | 22:07 |

| -shogungit:#shogun- [shogun] sonney2k pushed 1 new commit to master: https://github.com/shogun-toolbox/shogun/commit/1f7a6cca7f7bb58616eb0f2b9f884617c49b19f2 | 22:08 | |
| -shogungit:#shogun- shogun/master 1f7a6cc Soeren Sonnenburg: fixup cygwin build -> never use __reserved __keywords! | 22:08 | |
| wiking | hahah i bet blackburn woulld love this nameing: MILFeature ;) | 22:08 |
| @sonney2k | wiking, no blackburn introduced some convenience constructor + TMultipleCPinfo(uint32_t __from, uint32_t _N) : _from(__from), N(_N) { } | 22:09 |
| @sonney2k | and that kills it | 22:09 |
| @sonney2k | took me ages to find out :/ | 22:09 |
| wiking | :( | 22:10 |
| wiking | yeah i would have never guessed that __* is reserved in cygwin's gcc | 22:10 |
| @sonney2k | wiking, btw I wrote some example for dynarray and likely found the issue | 22:10 |
| wiking | sonney2k: great! | 22:10 |
| @sonney2k | we memset(0) the newly allocated memory | 22:10 |
| wiking | sonney2k: yeah i've seen that | 22:10 |
| @sonney2k | that doesn't work with objects of course | 22:10 |
| wiking | but it's only memsetting the new area no? | 22:10 |
| @sonney2k | kaboom | 22:10 |
| @sonney2k | sure but that would be and SGVector sitting on that new area | 22:11 |
| @sonney2k | memset it | 22:11 |
| @sonney2k | and then at some point it gets destructed | 22:11 |
| @sonney2k | I can easily fix this - only question is if sth relies on the memset 0 behavior | 22:11 |
| wiking | who's using DynArray? | 22:12 |
| @sonney2k | lots of stuff | 22:12 |
| wiking | ah well then yeah good luck with debugging it out | 22:12 |
| wiking | :( | 22:12 |
| wiking | btw something like this would be fun as well | 22:13 |
| wiking | http://lxr.linux.no/+trees | 22:13 |
| @sonney2k | good thing with the new malloc templates | 22:13 |
| @sonney2k | is though that one can fix it | 22:13 |
| @sonney2k | wiking, I actually think that this might not be a problem at all - let me commit and see what fails | 22:15 |
