| foulwall | sonne|work: I've mentioned in the email. we need a module named importlib, just pip it on the server. | 10:29 |
| sonne|work | foulwall: why do we need it? | 10:29 |
| foulwall | sonne|work: since we need to import the function at runtime, and the old __import__ is messy. | 10:31 |
| foulwall | sonne|work: importlib is just a wrapper of __import__ | 10:31 |
| sonne|work | foulwall: I don't understand why you need it though? Couldn't you just import everything statically? | 10:32 |
| foulwall | sonne|work: for the extensibility. when a new demo is written, there's no need to modify the views.py, just put them in the demos' directory and they'll work. | 10:38 |
| sonne|work | foulwall: ok I understand but for that you need to add checks that it doesn't import some random stuff | 10:39 |
| sonne|work | otherwise this introduces security issues | 10:39 |
| foulwall | it just import the modules with the prefix 'demos.' | 10:40 |
| foulwall | when import something that is not exist, it respond with a 404 | 10:42 |

| foulwall | hide the funtion in the modules that is not permitted to invoke by user. | 10:47 |
| sonne|work | foulwall: you basically have to make sure that no user input can harm the system | 10:49 |
| sonne|work | so try to avoid imports based on user import | 10:49 |
| sonne|work | function calls based on user input | 10:50 |
| sonne|work | always only call hardcoded stuff when you see certain input | 10:50 |

| @iglesiasg | sonne|work: done! | 11:01 |
| @iglesiasg | retweet it people! | 11:01 |
| vgorbati | hi guys, I am trying to write a unit test according to https://github.com/shogun-toolbox/shogun/issues/882, but when I run 'make' in shogun/tests/unit it runs 40 tests, without my newly added unit test (some other tests are missing too). However, the obj file is generated. Can anyone help me? | 11:03 |
| foulwall | iglesiasg: retweeted and followed you | 11:03 |
| wiking | wtf: mathematics/Statistics_unittest.cc:85:29: error: variable length array of non-POD element type 'SGSparseVector<float64_t>' | 11:04 |
| wiking | who wrote this?! | 11:05 |
| wiking | and who merged it?! | 11:05 |
| @iglesiasg | foulwall: nice, thank you! | 11:05 |
| wiking | ok i know who wrote it.... | 11:05 |

| wiking | it's fucking broken | 11:13 |
| wiking | ok here's a very funny unit test that fails | 11:16 |
| wiking | oh even better | 11:17 |
| wiking | i have a segfault | 11:17 |

| @iglesiasg | wiking: what does it say when it crashes? | 11:20 |
| wiking | iglesiasg: [ERROR] assertion m_current_values.vector && idx<get_num_labels() failed in file labels/Labels.cpp line 57 | 11:21 |
| wiking | unknown file: Failure | 11:21 |
| wiking | Unknown C++ exception thrown in the test body. | 11:21 |
| wiking | if i do the set_labels(vector) | 11:21 |
| wiking | it's even worse | 11:21 |
| wiking | it just segfaults | 11:21 |
| @iglesiasg | wiking: mm I don't see what is wrong either | 11:26 |

| @iglesiasg | wiking: I think it will work if you creat an SGVector<int32_t> with the labels and you give this to the CBinaryLabels constructor | 11:29 |
| wiking | iglesiasg: i've tried almost the same | 11:29 |
| @iglesiasg | but what you are doing you work too idd | 11:29 |
| wiking | instead of giving it to the constructor | 11:29 |
| wiking | use label->set_labels(vector) | 11:29 |
| wiking | that segfaults | 11:29 |
| wiking | :) | 11:29 |
| @iglesiasg | yeah.. but try using it in the constructor | 11:29 |
| @iglesiasg | I bet that will work | 11:30 |
| wiking | but what is the difference?! | 11:30 |
| wiking | i mean come on! | 11:30 |
| @iglesiasg | I am checking Labels code | 11:30 |
| wiking | that *must* work | 11:30 |
| @iglesiasg | yeah, but I see something that might be weird | 11:30 |
| wiking | yes for sure | 11:30 |
| -!- vgorbati_ [d4029f22@gateway/web/freenode/ip.212.2.159.34] has quit [Ping timeout: 245 seconds] | 11:30 | |
| @iglesiasg | wiking: does it work fine using the SGVector in the constructor? | 11:31 |
| sonne|work | wiking: labels are copied with one | 11:31 |
| sonne|work | (in constructor) | 11:31 |
| foulwall | sonne|work: hi sonne. | 11:31 |
| sonne|work | not with the set_labels() | 11:31 |
| sonne|work | foulwall: hi! | 11:31 |
| wiking | sonne|work: should we remove set_labels? | 11:32 |
| abinash | Hello I want to submit a code for the issue Probabilities for SVMs. What is the workflow for code submission | 11:32 |
| sonne|work | wiking: no | 11:32 |
| sonne|work | wiking: it should work | 11:32 |
| foulwall | sonne|work: Excuse me. and I've changed the demoHandler into a more security one. | 11:32 |
| wiking | ctor version works | 11:32 |
| @iglesiasg | sonne|work, wiking : I think it might be something related to m_current_values and m_labels | 11:32 |
| wiking | sonne|work iglesiasg [ERROR] assertion m_current_values.vector && idx<get_num_labels() failed in file labels/Labels.cpp line 57 | 11:33 |
| wiking | with set_labels(vector) | 11:33 |
| @iglesiasg | set_labels and what wiking was using does not set m_current_values I think | 11:33 |
| foulwall | sonne|work: but it's a bit messy | 11:33 |
| sonne|work | foulwall: btw please dont' do things like import * but just import what you need | 11:33 |
| foulwall | sonne|work: I've changed that. | 11:33 |
| foulwall | sonne|work: and i'll never do that. | 11:33 |
| sonne|work | iglesiasg: ahh I see | 11:33 |
| @iglesiasg | sonne|work: maybe it is a bug, I am not sure though | 11:34 |
| wiking | iglesiasg: well for sure it's a bug :) | 11:34 |
| sonne|work | wiking: no | 11:34 |
| sonne|work | we have 2 functions | 11:34 |
| sonne|work | set_labels | 11:34 |
| sonne|work | and set_values | 11:34 |
| sonne|work | they don't set both | 11:34 |
| wiking | sonne|work: set_label(idx, value) | 11:34 |
| wiking | ? | 11:34 |
| sonne|work | only constructor does | 11:34 |
| wiking | sonne|work: using set_labels(vector) and set_label(idx, value) | 11:35 |
| sonne|work | that's not nice though - but no idea (currenlty) how to do it better | 11:35 |
| wiking | will not work with ROC | 11:35 |
| wiking | and this is a bug | 11:35 |
| wiking | as we let this happen | 11:35 |
| sonne|work | wiking: so do we ever want to be able to set these arrays *separately* | 11:36 |
| sonne|work | iglesiasg: could you please help abinash? | 11:36 |
| wiking | sonne|work: currently i have a usecase where yes i would like to | 11:36 |
| sonne|work | iglesiasg: thanks for twittering... | 11:36 |
| @iglesiasg | sonne|work: but what do m_labels and m_current_values represent? There must be a difference | 11:36 |
| @iglesiasg | sonne|work: no problem | 11:36 |
| @iglesiasg | hey abinash | 11:36 |
| @iglesiasg | abinash: we have recently started using git flow in our development workflow | 11:37 |
| sonne|work | wiking, iglesiasg - yes sure there is a difference: consider e.g. binary labels. m_labels would then just be -1/+1 values | 11:37 |
| wiking | and what the hell is set_values anyways? | 11:37 |

| -!- travis-ci [~travis-ci@ec2-23-23-3-13.compute-1.amazonaws.com] has left #shogun [] | 11:38 | |
| @iglesiasg | abinash: see this mail on the mailing list for more info: http://article.gmane.org/gmane.comp.ai.machine-learning.shogun/3342 | 11:38 |
| sonne|work | wiking: the confidence values | 11:39 |
| wiking | sonne|work: and then set_labels ? | 11:39 |
| @iglesiasg | sonne|work: so m_labels would be the -1/+1 got it, but m_current_values? | 11:40 |
| sonne|work | iglesiasg: indeed no idea | 11:40 |
| sonne|work | I guess some subset stuff? | 11:40 |
| @iglesiasg | I thought so | 11:41 |
| @iglesiasg | some of Heiko's magic for x-val | 11:41 |
| wiking | mmm we need to enable unit testing on travis | 11:41 |
| @iglesiasg | wiking, sonne|work: even if it is not a bug, I think it is a bit confusing | 11:42 |
| sonne|work | it is totally | 11:42 |
| sonne|work | I don't understand it | 11:42 |
| @iglesiasg | I wouldn't understand why the test didn't work without digging into Labels stuff | 11:42 |
| wiking | sonne|work: so now my answer for yesterday: shogun auROC: 0.900061 vs weka auroc: 0.955 | 11:42 |
| sonne|work | we have to ask hypergenious heiko to parse that I guess | 11:42 |
| @iglesiasg | maybe we should rename so stuff | 11:42 |
| @iglesiasg | sonne|work: sure, let's see what he tells | 11:42 |
| @iglesiasg | us | 11:43 |
| wiking | sonne|work: so we are still off by a lot | 11:44 |

| -!- vgorbati [d4029f22@gateway/web/freenode/ip.212.2.159.34] has joined #shogun | 11:46 | |
| wiking | sonne|work: so now what's happening is that i use PolyKernel with 2.0 exponent | 11:46 |
| wiking | sonne|work: + normalize the input with p=2.0 | 11:47 |
| wiking | i.e. euclidean distance | 11:47 |
| wiking | and use libsvm with C=1.0 | 11:47 |
| wiking | bias enabled | 11:47 |
| wiking | epsilon set to 1E-12 | 11:47 |
| wiking | same settings in weka, using their smo | 11:48 |
| wiking | and of course run it on the same train/test set | 11:48 |
| wiking | i can right away try different kernels if u want me to, as i suspected that it should be better with other kernels | 11:50 |
| wiking | and using kernel normalization does not change the auroc | 11:50 |
| sonne|work | wiking: so with weka you use poly kernel | 11:52 |
| wiking | sonne|work: yes | 11:52 |
| sonne|work | in-homogeneous ? | 11:53 |
| wiking | sonne|work: the non-normalized polykernel | 11:53 |
| sonne|work | then dont' normalize data in shogun either | 11:53 |
| wiking | yeah i've just tried both | 11:53 |
| sonne|work | by default the poly kernel does | 11:53 |
| sonne|work | set the identity kernel normalizer | 11:53 |
| wiking | ok | 11:55 |

| wiking | HeikoS: today you have a lot of task :))) | 11:55 |
| HeikoS | what | 11:55 |
| wiking | HeikoS: well first of all u merged code that breaks unit testing | 11:56 |
| HeikoS | just arrived at werk :D | 11:56 |
| HeikoS | work | 11:56 |
| HeikoS | oh | 11:56 |
| HeikoS | thats good, which ones? | 11:56 |
| wiking | HeikoS: second check the rocevaluator unittest | 11:56 |
| HeikoS | already did | 11:56 |
| wiking | HeikoS: as i have nooooo clue why that fails | 11:56 |
| HeikoS | it fails? | 11:56 |
| wiking | HeikoS: yeps big time :) | 11:56 |
| * sonne|work ~~~ooo~~~~~who~~let~~~the~~~dogs~~~out~~~ooo~~~~ | 11:56 | |
| wiking | sonne|work: with identitynormalizer: 0.910194 | 11:57 |
| HeikoS | sonne|work: ha you are alright? :) | 11:57 |
| HeikoS | wiking: what dies it return? | 11:57 |
| wiking | HeikoS: well ASSERT error | 11:57 |
| sonne|work | HeikoS: wiking is biting you already :) | 11:57 |
| wiking | HeikoS: cd tests/unit && make | 11:57 |
| wiking | and you'll see | 11:57 |
| sonne|work | wiking: then don't normalize in shogun - like you do in weka | 11:57 |
| wiking | sonne|work: i mean i'm normalizing the input itself | 11:58 |
| wiking | sonne|work: i shouldn't? | 11:58 |
| HeikoS | wiking: does the buildbot fail? | 11:58 |
| wiking | HeikoS: afaik buildbot doesn't run on develop branch | 11:58 |
| wiking | or? | 11:58 |
| HeikoS | I see | 11:58 |
| HeikoS | oh thats not good | 11:58 |
| HeikoS | I am confused | 11:59 |
| HeikoS | the buildbot runs on master? | 11:59 |
| HeikoS | and we commit to develop? | 11:59 |
| HeikoS | why is that? | 11:59 |
| wiking | HeikoS: yes | 11:59 |
| wiking | HeikoS: because travis should do tit :) | 11:59 |
| wiking | HeikoS: and it actually does most of it :P | 11:59 |
| HeikoS | I see | 11:59 |
| sonne|work | wiking: ohh man I guess you have to start from the beginning | 11:59 |
| HeikoS | ehm? | 11:59 |
| sonne|work | wiking: you got data - you normalize than save that data | 11:59 |
| HeikoS | yes pls :) | 11:59 |
| HeikoS | wiking so when does code migrate from develop to master? | 12:00 |
| sonne|work | then use exactly that data in weka and shogun? | 12:00 |
| wiking | sonne|work: L2Norm(input) -> PolyKernel(Exp=2.0) -> LIBSVM | 12:00 |
| wiking | HeikoS: release | 12:00 |
| sonne|work | wiking: nope | 12:00 |
| wiking | sonne|work: that's the current pipeline for the data | 12:00 |
| wiking | HeikoS: hahahah you grasped the most important part of the untittest :D | 12:01 |
| HeikoS | wiking: I see | 12:02 |
| HeikoS | what I dont really get is, why dont we run the buildbot on develop? | 12:02 |
| wiking | HeikoS: i mean with your comment... the problem is that currently that little snippet fails | 12:02 |
| wiking | HeikoS: hahahahahahahah | 12:02 |
| wiking | HeikoS: travis not enough? | 12:02 |
| HeikoS | wiking: so what does it return | 12:02 |
| HeikoS | wiking: not all architectures | 12:03 |
| wiking | HeikoS: [ERROR] assertion m_current_values.vector && idx<get_num_labels() failed in file labels/Labels.cpp line 57 | 12:03 |
| HeikoS | so if we have errors that would not be detected there we will only notice when migrating to master | 12:03 |
| wiking | HeikoS: ok i guess then we have to discuss this with sonne|work | 12:03 |
| HeikoS | wiking: I see, so this seems to be a different problem | 12:03 |
| HeikoS | wiking: also this warning stuff, its so nice to see them in the buildbot | 12:03 |
| HeikoS | wiking: wait | 12:04 |
| HeikoS | I actually saw commits by lambday compiling on the buildbot | 12:04 |
| HeikoS | why is that? | 12:04 |
| wiking | HeikoS: PR | 12:04 |
| HeikoS | did he commit to master and I did not realise? | 12:04 |
| wiking | or no | 12:04 |
| HeikoS | explain for dumb people please ;) | 12:04 |
| wiking | pr is not buildboted | 12:04 |
| wiking | i have no idea | 12:04 |
| wiking | HeikoS: explain me why that code fails | 12:04 |
| wiking | ;) | 12:04 |
| wiking | i'm really dumb as well in that case | 12:04 |
| HeikoS | wiking: ok will do | 12:04 |
| HeikoS | wiking: I notices some warnings in lambdays code in the build bot log | 12:05 |
| HeikoS | and then he fixed them and the warnings went away | 12:05 |
| wiking | HeikoS: https://github.com/shogun-toolbox/shogun/commits/master | 12:05 |
| wiking | because it was merged into master for some reason | 12:05 |
| wiking | ;P | 12:05 |
| wiking | which is NONO NOOOO good | 12:06 |
| wiking | but i guess you did not realise | 12:06 |
| wiking | that he sent the PR | 12:06 |
| HeikoS | no I did not | 12:06 |

| HeikoS | I see | 12:06 |
| HeikoS | okay | 12:06 |
| wiking | dont lie my friend, github catches u | 12:06 |
| wiking | ;) | 12:06 |
| HeikoS | haha | 12:06 |
| HeikoS | so I have to make sure to merge into develop | 12:06 |
| wiking | well just check the PR | 12:07 |
| wiking | whether it's sent for master or develop branch | 12:07 |
| HeikoS | ok | 12:07 |
| HeikoS | good | 12:07 |
| HeikoS | to know | 12:07 |
| wiking | if it's coming for master branch | 12:07 |
| HeikoS | and then travis catches things | 12:07 |
| wiking | just drop it straight away | 12:07 |
| wiking | we dont accept PR for master | 12:07 |
| HeikoS | wiking, and then when we release we merge develop into master? | 12:07 |

| HeikoS | good that you tell me these things :) | 12:08 |
| wiking | HeikoS: indeed we do the merging | 12:08 |
| wiking | HeikoS: now it's going to be very interesting | 12:08 |
| HeikoS | wiking: so could you add something to travis that collects warnings? | 12:08 |
| wiking | HeikoS: becuase you got some stuff into master that is not in develop | 12:08 |
| HeikoS | also for libshogun I would even vote to allow warnings as errors | 12:08 |
| HeikoS | as for python | 12:08 |
| HeikoS | but you have to ask sonne|work and lisitsyn on this | 12:09 |
| wiking | HeikoS: so now we'll have to do some funky shit merging | 12:09 |
| HeikoS | wiking: shit, sorry for that | 12:09 |
| HeikoS | well, we can rebase right? | 12:09 |
| wiking | HeikoS: heheh that's going to be a merge | 12:09 |
| wiking | and not a simple rebase | 12:09 |
| wiking | HeikoS: anyhow | 12:10 |

| wiking | HeikoS: no other fails | 12:12 |

| wiking | sonne|work: my input is DenseFeatures<float32_t> | 12:13 |
| wiking | sonne|work: and lets say i want to use Chi2Kernel | 12:13 |
| wiking | sonne|work: Chi2Kernel.cpp:61 | 12:13 |
| wiking | float64_t* avec= ((CDenseFeatures<float64_t>*) lhs)->get_feature_vector(idx_a, alen, afree); | 12:13 |
| wiking | this will lead to a segfault | 12:13 |
| wiking | :( | 12:13 |
| wiking | i mean not this line | 12:13 |
| wiking | but because of this | 12:14 |
| wiking | soooooo | 12:14 |
| wiking | how can we assure that no such case every can happen? | 12:14 |
| wiking | i.e. if the input is not CDenseFeatures<float64_t> | 12:14 |
| wiking | then at least it fails with an assert | 12:14 |
| wiking | and not a segfault | 12:14 |
| HeikoS | wiking: easy explanation | 12:14 |
| HeikoS | ROC works on the scores | 12:15 |
| wiking | HeikoS: okok listening, what's the fix, is it already in? | 12:15 |
| HeikoS | not the integer labels | 12:15 |
| HeikoS | I suggest the following: | 12:15 |
| HeikoS | add a proper error message instead of the assert | 12:15 |
| HeikoS | then, change the test a bit so that value vector is set | 12:15 |
| HeikoS | I will do that | 12:15 |
| wiking | HeikoS: ok just you know that this is confusing a lot | 12:15 |
| wiking | right? | 12:15 |
| HeikoS | what? | 12:16 |
| HeikoS | wiking: the test is weird anyway | 12:16 |
| wiking | HeikoS: well this that we have set_label and set_value | 12:16 |
| HeikoS | ROC on binary integers doesnt make any sense | 12:16 |
| HeikoS | set_value doenst work | 12:17 |
| HeikoS | if the value vector is not set | 12:17 |
| wiking | HeikoS: even if it doesn't make sense | 12:17 |
| HeikoS | ok | 12:17 |
| wiking | we should not die like this imo | 12:17 |
| HeikoS | wiking: true | 12:19 |
| HeikoS | we should have some thoughts on the label vs values vs scores design | 12:19 |
| HeikoS | lisitsyn: ^ | 12:19 |
| wiking | holaaa! | 12:21 |
| wiking | sonne|work: ok now i've beaten weka | 12:21 |
| wiking | sonne|work: as i suspected ;) | 12:21 |
| wiking | sonne|work: but i had the segfaults because of the prev error i was mentioning | 12:21 |
| HeikoS | wiking, sonne|work, lisitsyn we should have better error messages: I think it would be good to include the name of the method one is in class::name(): Error message | 12:22 |
| HeikoS | I never know where the asserts are coming from | 12:22 |
| wiking | HeikoS: lisitsyn sonne|work we should have a discussion about this: we have DenseFeatures<T> but then for example in some preprocessors and kernels have DenseFeatures<float64_t> hardcoded... this will cause segfaults... :( | 12:22 |
| wiking | somehow it'd be great if we could do this part automatically | 12:22 |
| wiking | e.g. add a preprocessor to the DenseFeature and that will use the right 'version' (template paramter) of the preprocessor | 12:23 |
| wiking | any thoughts on this one? | 12:23 |
| HeikoS | wiking: the test might also fail if you have only labels from one class (might happen since random is used) | 12:26 |
| HeikoS | better to use odd/even for labels | 12:26 |
| wiking | HeikoS: heheh ok ok | 12:26 |
| wiking | HeikoS: i admit | 12:26 |
| wiking | not the most sofisticated test | 12:26 |
| wiking | i just wanted to push something to show that something is wrong atm | 12:27 |
| HeikoS | wiking: I see, thats good | 12:28 |

| HeikoS | lambday: hi! | 12:39 |
| lambday | should we always use SG_MALLOC while initializing SG-classes? | 12:39 |
| HeikoS | lambday: just a quick note: if you are doing PR's please always do them on the develop branch | 12:40 |
| HeikoS | lambday: the SGVector SGMatrix etc are treated differently | 12:40 |
| HeikoS | we have automatic reference counting for them | 12:40 |
| HeikoS | you *always* create them on the stack | 12:40 |
| HeikoS | rest is done internally | 12:40 |
| HeikoS | so always SGVector=SGVector(10) | 12:40 |
| HeikoS | never SGVector*=new SGVector(10) | 12:40 |
| @lisitsyn | do not do SGVector a = SGVector(10); | 12:41 |

| lambday_ | sorry I got disconnected | 12:44 |
| @lisitsyn | HeikoS: doc warnings? | 12:44 |
| HeikoS | in particular I like them for python since doxygen comments cannot be forgotten | 12:44 |
| lambday_ | in one of my previous PR, I did something like SGSparseVector<float64_t> v[size-1];.... viktor and sonne|work pointed out that its not right | 12:44 |
| @lisitsyn | I do not like that | 12:44 |
| HeikoS | lisitsyn: yes, and also libshogun gcc | 12:44 |
| HeikoS | why? | 12:44 |
| @lisitsyn | I'd rather get rid of all the dummy doc we have | 12:44 |
| @lisitsyn | it is useless | 12:45 |
| HeikoS | lisitsyn: yes, do not merge dummy doc | 12:45 |
| HeikoS | but the warning thing then helps you remembering to check | 12:45 |
| HeikoS | since I tend to forget | 12:45 |
| HeikoS | and others do to | 12:45 |
| @lisitsyn | HeikoS: yes but it is not an error | 12:45 |
| HeikoS | to get rid of dummy is responsibility of PR merger | 12:45 |
| HeikoS | lisitsyn: okay agreed | 12:45 |
| HeikoS | what about gcc warnings? | 12:45 |
| HeikoS | my point is just: we tend to collect them | 12:46 |
| @lisitsyn | HeikoS: I do not mind treating them as errors | 12:46 |
| HeikoS | since its easy to oversee | 12:46 |
| @lisitsyn | HeikoS: we should enable -Weffc++ :D :D | 12:46 |
| HeikoS | whats that? | 12:46 |
| @lisitsyn | warnings from the effective C++ book by meyers | 12:46 |
| HeikoS | what do they tell you? | 12:47 |
| @lisitsyn | I expect thousands in shogun | 12:47 |
| @lisitsyn | virtual destructor, operator=, blabla | 12:47 |
| HeikoS | I dont wont to be mean to people, just want to avoid piling up warnings | 12:47 |
| HeikoS | but I guess one can also just check the warnings | 12:47 |
| HeikoS | wiking: could we collect them in travis and output at the end? or make it yellow as in the buildbot? | 12:48 |

| HeikoS | thats how I read it | 12:58 |
| @lisitsyn | HeikoS: yes | 13:00 |
| @lisitsyn | HeikoS: with [] it probably means create vector v and get its size-1 element | 13:01 |

| -foulwall:#shogun- I'll add some animation on 'clear' | 15:11 | |
| foulwall | sonne|work: I'm wondering what kind of animation can be added to the cluster demo. | 15:12 |
| sonne|work | foulwall: yeah would be cool | 15:12 |
| sonne|work | foulwall: make the diameter of the circle from 0 -> r | 15:12 |
| @iglesiasg | foulwall: if you are using k-means, you can do a nice one | 15:12 |
| @iglesiasg | foulwall: since this method is iterative | 15:13 |
| sonne|work | iglesiasg: he only has the end result | 15:13 |
| sonne|work | it's the shogun output | 15:13 |
| @iglesiasg | foulwall: mmm however that would require intermediate results | 15:13 |
| @iglesiasg | sonne|work: idd I noted that | 15:13 |
| foulwall | sonne|work: ok | 15:13 |
| @iglesiasg | sonne|work: I think it is worth trying | 15:13 |
| sonne|work | iglesiasg: the same would work for an svm | 15:13 |
| sonne|work | or svr | 15:13 |
| sonne|work | think of it just training one iteration | 15:14 |
| @iglesiasg | aham true | 15:14 |
| @iglesiasg | I didn't come up with it for the svm and svr | 15:14 |
| HeikoS | foulwall, could you connect the lines between the points in the regression function? | 15:15 |
| HeikoS | when you make the kernel width very small you see the individual points | 15:16 |
| foulwall | HeikoS: I note that, wait me and I'll fix that | 15:16 |
| HeikoS | foulwall, this is really cool! | 15:17 |
| foulwall | HeikoS: thank you | 15:17 |
| HeikoS | foulwall: you could do this for the GP classifier and regression | 15:17 |
| HeikoS | foulwall, you know what would be even cooler? | 15:17 |
| HeikoS | if you could plot the underlying distribution | 15:17 |
| HeikoS | like a heatmap | 15:17 |
| HeikoS | at least for classifier | 15:17 |
| foulwall | HeikoS: that's what I want to do next | 15:17 |

| juanmanpr | hello guys, about gsoc, what kine of profiles are you searching on the students? | 16:22 |
| juanmanpr | I am studying master in computer vision, and im really interested in machine learning | 16:23 |
| juanmanpr | i have experience in C, C++, Matlab, and a little python | 16:23 |
| HeikoS | juanmanpr: we are looking for motivated people than can code and have some background in the topic their project is about | 16:24 |
| HeikoS | juanmanpr: the best way to get involved is to start sending patches and discuss project ideas | 16:24 |
| HeikoS | with the mentors | 16:24 |
| juanmanpr | But, is there any special requirement that you are looking, for example to Interface and develop the general quadratic solver library libqp | 16:24 |
| juanmanpr | ok, where can I finf a list of menthors for shogun? | 16:25 |
| HeikoS | on our ideas page | 16:25 |
| juanmanpr | thanks, i'll take a look | 16:25 |
| HeikoS | there is no "hard" requirement, you just have to convince us of you :) | 16:25 |
| HeikoS | as a computer vision student, you should have the right background | 16:25 |
| juanmanpr | You also would like to see some code, right? | 16:26 |
| HeikoS | so just show us that you can code and are motivated by sending patches :) see our issues list on github for initial tasks you could do | 16:26 |
| HeikoS | yes, it is a requirement for your application to be considered | 16:26 |
| HeikoS | not only show | 16:26 |

| foulwall | dvalcarce: we can work together and make better demos. | 17:41 |
| dvalcarce | yeah, that's a good idea | 17:42 |
| dvalcarce | i was thinking the same thing | 17:42 |
| foulwall | dvalcarce: :-) | 17:42 |
| dvalcarce | i see your regression demo, it's cool | 17:43 |
| dvalcarce | maybe we can split server and client sides work | 17:43 |
| dvalcarce | i don't know what sonney2k will think about it | 17:43 |
| foulwall | dvalcarce: good idea. | 17:44 |

| dvalcarce | let's ask him then :P | 17:46 |
| dvalcarce | which part do you prefer? | 17:46 |
| dvalcarce | because right now i think we are doing duplicated work on django side | 17:47 |
| dvalcarce | i think we should define some basic interfaces | 17:48 |
| foulwall | both are ok, and the front end needs more creativity. | 17:49 |
| dvalcarce | i agree, bootstrap is beautiful but it isn't enough | 17:50 |

| vgorbati | lisitsyn, hi are you there? | 17:55 |
| dvalcarce | we need server communication, but we don't want a ddos | 17:56 |
| foulwall | dvalcarce: yes. | 17:57 |
| dvalcarce | some kind of authentication? | 17:57 |
| dvalcarce | or maybe it is too overhead because of some demos? | 17:57 |
| foulwall | dvalcarce: auth is easy to implement but we need somekind of elastic way to make the demo code extensibility | 17:59 |
| foulwall | dvalcarce: code reuse and general interface | 17:59 |
| foulwall | but a general interface may cause some function exposed to the bad user. | 18:02 |
| dvalcarce | we can implement data size or computing time limitations | 18:04 |

| @lisitsyn | vgorbati: what you may do now is to replace this 100% check with something weaker | 20:54 |

| vgorbati | lisitsyn: experimentally find some percentage, that will pass? | 20:55 |
| @lisitsyn | vgorbati: kind of | 20:55 |
| @lisitsyn | vgorbati: you may check the other thing though | 20:56 |
| vgorbati | lisitsyn: ? | 20:56 |
| @lisitsyn | whether weights are preserved | 20:56 |
| @lisitsyn | like for any vector x in initial space | 20:56 |
| @lisitsyn | the linear combination weights are the same | 20:57 |
| @lisitsyn | for initial space and embedded space | 20:57 |
| vgorbati | well, that will complicate things a little bit) | 20:58 |
| vgorbati | it's like doing the big part of LLE itself | 20:59 |
| vgorbati | lisitsyn: I guess I can't receive the neighbors weights from CLocallyLinearEmbedding somehow, can I/ | 21:01 |
