| harshit_ | n4nd0: Hola ! | 07:12 |
| n4nd0 | harshit_: ey! how is it going? | 07:16 |
| harshit_ | hey, my TSVM is almost ready but the problem is it takes too much time to converge | 07:17 |
| harshit_ | whereas in svmlin time it doesn't takes that much time | 07:17 |
| harshit_ | dont knw whats going on!! | 07:18 |
| n4nd0 | harshit_: aham, so there must something different between both implementations right=? | 07:18 |
| n4nd0 | mmmm about time of convergence, have you checked if they use a kind of tolerance value | 07:19 |
| harshit_ | yeah, but I havnt changed that part much in shogun. that was already in shogun | 07:19 |
| harshit_ | tolerance value ?? | 07:19 |
| n4nd0 | yeah, it was just an idea ... | 07:19 |
| harshit_ | how to check that..? | 07:19 |
| n4nd0 | looking at their code | 07:19 |
| n4nd0 | anyhow, are you confident then that it is not caused by the code you have written but by the other code? | 07:20 |
| harshit_ | might be .! dont know exactly at this time .. have to debug a lil more | 07:21 |
| harshit_ | n4nd0: Hows your covertree | 07:21 |
| n4nd0 | harshit_: I have to discuss with blackburn some details before starting to do the port | 07:25 |
| n4nd0 | but it looks promising, it is very fast | 07:25 |
| harshit_ | great .. Maybe after completing on KNN we can apply it on K-Means , | 07:25 |
| harshit_ | what sya | 07:25 |

| gsomix | hi all | 08:16 |
| @sonney2k | we are currently investigating if we can handle all 9 or just 8 (as we requested) | 08:16 |
| @sonney2k | s/just/'just'/ | 08:16 |
| @sonney2k | it is a huuuge number | 08:16 |
| gsomix | and good morning | 08:16 |
| n4nd0 | gsomix: good morning | 08:16 |
| n4nd0 | sonney2k: really, could it be a problem with the number of mentors? | 08:16 |
| gsomix | 9? | 08:18 |
| n4nd0 | gsomix: yeah | 08:19 |
| gsomix | time to vodka | 08:19 |
| n4nd0 | haha | 08:19 |
| n4nd0 | c'mon isn't it like 10 around there? :P | 08:19 |
| @sonney2k | n4nd0, yes | 08:24 |
| n4nd0 | that's not good | 08:24 |
| @sonney2k | not enough mentors | 08:24 |
| @sonney2k | we had more ideas but for some ideas we did not get good proposals | 08:24 |
| @sonney2k | so these mentors won't mentor anything | 08:24 |
| @sonney2k | so in fact we are 7-8 mentors | 08:25 |
| @sonney2k | alright | 08:25 |
| @sonney2k | have to leave train | 08:25 |
| n4nd0 | tty later | 08:25 |

| * gsomix going to classes about computer networks. | 08:46 | |
| gsomix | cu | 08:46 |
| gsomix | *is going | 08:46 |
| sonne|work | n4nd0: which timezone are you in? | 09:08 |
| sonne|work | gsomix: which timezone are you in? | 09:08 |
| sonne|work | blackburn: timezone? | 09:08 |
| sonne|work | I need to collect to know when you all are online... | 09:08 |
| blackburn | sonne|work: both me and gsomix are in +4 | 09:09 |
| n4nd0 | sonne|work: CEST (UTC+2) | 09:09 |
| n4nd0 | sonne|work: I think we are in the same | 09:10 |
| sonne|work | n4nd0: yes indeed | 09:10 |
| sonne|work | does anyone know which timezone pluskid is in? | 09:10 |
| blackburn | +8 | 09:10 |
| sonne|work | and heiko? | 09:10 |
| blackburn | I guess +1? | 09:11 |
| n4nd0 | btw, if someone had any doubt, apart from being pretty fast, JL's cover tree gives correct results :) | 09:11 |
| sonne|work | heh | 09:11 |
| sonne|work | nice | 09:11 |
| sonne|work | n4nd0: so then it is even more clear that we want it :) | 09:11 |
| n4nd0 | sonne|work: I'm working on that ;) | 09:12 |
| sonne|work | blackburn: wiking? | 09:12 |
| sonne|work | and jacob? | 09:13 |
| blackburn | sonne|work: belgium, same? | 09:13 |
| blackburn | no idea about jacob | 09:13 |
| sonne|work | harshit? and philippe? | 09:13 |
| blackburn | harshit +5 or +6 | 09:13 |
| n4nd0 | sonne|work: philippe is in France so I guess he has the same | 09:13 |
| blackburn | philippe france | 09:13 |
| sonne|work | lets better make sure when they pop up | 09:15 |

| wiking | y | 09:45 |
| wiking | yes | 09:45 |
| sonne|work | kthx | 09:46 |
| blackburn | seems you guys are having shortest word competition | 09:47 |
| wiking | :> | 09:47 |
| sonne|work | I've updated the website http://shogun-toolbox.org/ | 10:18 |
| sonne|work | not sure if a github banner is a good idea but hey I added it for now | 10:19 |
| sonne|work | also removed broken links to tuebingen mpg | 10:19 |
| blackburn | yes it is | 10:19 |
| n4nd0 | nice | 10:20 |
| sonne|work | ahh but I got the link wrong | 10:20 |
| blackburn | sonne|work: we need new description I think | 10:20 |
| sonne|work | hah | 10:20 |
| sonne|work | after gsoc :) | 10:20 |
| sonne|work | and volunteers welcome! | 10:20 |
| n4nd0 | what description are you talking about guys? | 10:21 |
| blackburn | n4nd0: shogun is blablabla | 10:21 |
| n4nd0 | the paragraph on top of the page? | 10:21 |

| blackburn | sonne|work: it seems jacob is in eastern usa - msu.edu stands for michigan state univ | 10:50 |
| sonne|work | no overlap in this set I guess then | 10:51 |
| sonne|work | not good | 10:51 |
| blackburn | sonne|work: may be some saturday evening would work | 10:51 |
| blackburn | however it is saturday heh | 10:52 |
| pluskid | cool to hear good news about 9 slots! | 10:52 |
| sonne|work | pluskid: you were UTC+8 right? | 10:52 |
| pluskid | GMT+8, is it the same as UTC+8? | 10:53 |
| pluskid | I'll google it | 10:53 |
| blackburn | yes | 10:53 |
| pluskid | sonne|work: yes, UTC+8 | 10:53 |
| pluskid | the homepage github link point to http://github.com/you , is it intended? | 10:56 |
| blackburn | lol | 10:57 |
| pluskid | and the "you" actually has 16 followers | 10:57 |
| pluskid | though no public repo | 10:57 |
| pluskid | Previously I thought one mentor can be on multiple project, am I wrong? | 10:59 |
| blackburn | you mean one person? | 11:00 |
| pluskid | yes | 11:00 |
| blackburn | yes that can be | 11:00 |
| pluskid | one person (as a mentor) can be in several projects(ideas), isn't it? | 11:01 |
| pluskid | I'm not sure | 11:01 |
| sonne|work | pluskid: yes | 11:01 |
| sonne|work | but we try to restrict things | 11:01 |
| sonne|work | to be 1vs1 | 11:01 |
| pluskid | oh, that might be good for better quality | 11:02 |
| sonne|work | which means 7-8 slots is what we will actually use | 11:03 |
| sonne|work | (the downside of things) | 11:03 |
| pluskid | :-/ | 11:03 |
| wiking | blackburn: hey man i'm testing the multi class linear machine... and i'm not soooo satisfied with the speed :D | 11:07 |
| blackburn | wiking: which one? | 11:08 |
| wiking | classification is super fast :) | 11:08 |
| wiking | MulticlassLibLinear | 11:08 |
| blackburn | how much time? d? N? | 11:08 |
| blackburn | if you do modelselection enable save train state option | 11:09 |
| blackburn | to make training a little faster | 11:09 |

| blackburn | wiking: what is epsilon? | 11:13 |
| wiking | 1e-5 | 11:13 |
| blackburn | uh that is tough | 11:13 |
| blackburn | try larger no need to 1e-5 | 11:13 |
| wiking | 1e-2? | 11:14 |
| blackburn | yeah 1e-2 or 1e-3 | 11:14 |
| wiking | it's funny | 11:16 |
| wiking | i have a new kernel | 11:16 |
| wiking | but it only works with libsvm | 11:16 |
| wiking | other svm die because it cannot find enough support vectors :( | 11:16 |
| wiking | but with libsvm it works nice | 11:16 |
| -!- pluskid [~chatzilla@111.120.11.250] has joined #shogun | 11:17 | |
| blackburn | wiking: is it proper normalized then? | 11:18 |
| wiking | blackburn: you mean the kernel? yes | 11:19 |
| blackburn | strange | 11:19 |
| wiking | sqrtdiagkernelnormalizer.. | 11:19 |
| wiking | any suggestion for metal earners? | 11:21 |
| wiking | hahahah metalearners :) | 11:21 |
| wiking | stupid autocorrection | 11:21 |
| wiking | :> | 11:21 |
| blackburn | metal earner lol | 11:21 |
| blackburn | wiking: what kind of metalearner? | 11:22 |
| wiking | well anything that does a consensus in a good way between various ML classifications | 11:22 |
| wiking | because i have some good results with different features.... separately | 11:22 |
| wiking | but when i add them together (even with combined kernel) the result degrades :) | 11:23 |
| blackburn | uh | 11:23 |
| wiking | so it's pretty annoying :) | 11:24 |
| sonne|work | wiking: then your normalization sucks | 11:24 |
| wiking | sonne|work: hahahahaha any suggestions ? :) | 11:25 |
| pluskid | blackburn: I find why LinearRidgeRegression is acting weird :) | 11:25 |
| blackburn | pluskid: why? | 11:25 |
| pluskid | a small bug | 11:25 |
| pluskid | the matrices are not initialized | 11:25 |
| pluskid | simple fix :p | 11:25 |
| sonne|work | :) | 11:26 |
| blackburn | sonne|work: bad boy | 11:26 |
| sonne|work | wiking: well do you have the data or do I have it ... | 11:26 |
| * sonne|work smacks sonney2k | 11:26 | |
| wiking | :>>> | 11:26 |
| * sonne|work luckily I am at work | 11:26 | |
| pluskid | :> | 11:26 |
| pluskid | btw I have some suggestions about CMath::twonorm and several related functions | 11:30 |
| pluskid | the template function is returning the same type as the argument | 11:30 |
| pluskid | for example, when you calculate twonorm for an int32_t vector | 11:30 |
| pluskid | you get int32_t result, which would loss a lot of information | 11:31 |
| wiking | pluskid: yeah | 11:31 |
| wiking | ah ok | 11:31 |
| pluskid | I suggest we use float64_t or something for all input types | 11:31 |
| wiking | i think in case of qnorm is not like that | 11:31 |
| wiking | afaik | 11:31 |
| pluskid | why? | 11:31 |
| pluskid | have to leave for a while | 11:32 |
| wiking | mmm wait i'm mixing now | 11:32 |
| pluskid | cu later | 11:32 |
| wiking | ah yeah | 11:32 |
| wiking | qnorm is like that as well | 11:32 |
| wiking | shouldn't be it should be something like pluskid says | 11:32 |
| wiking | there's anyways an explicit casting there | 11:34 |
| wiking | when u return float64_t as class T | 11:34 |
| sonne|work | wiking: in case when we compute a float64_t anyways yes | 11:35 |
| wiking | man it's early here in my head | 11:35 |
| wiking | i meant implicit casting.. | 11:35 |
| wiking | but anyhow yeah it should always return something like float64_t even if the input vector is an int32_t | 11:35 |
| sonne|work | wiking: there is always a trade-off | 11:41 |
| sonne|work | this can be wanted or not | 11:41 |
| sonne|work | when numbers are small the pure int32_t based compuation will use MMX and be very fast | 11:41 |
| sonne|work | and correct | 11:41 |
| sonne|work | if numbers become too big one needs the float64_t based variant | 11:42 |
| sonne|work | computation is slow but this is required for large numbers | 11:42 |
| sonne|work | so YMMV | 11:42 |
| pluskid | in our current implementation, float64_t is always used in computaion | 11:46 |
| pluskid | just when we are returnining, it gets casted to T | 11:46 |
| pluskid | I think the trade-off sonne|work mentioned is true | 11:46 |
| pluskid | but what we are discussing here is not that issue | 11:46 |
| pluskid | we are thinking about whether we should return T or float64_t ? | 11:47 |

| wiking | what's a good kernel for sparse features apart from linear? | 14:37 |
| n4nd0 | well guys I have the first timing results of JL cover tree used from shogun! | 14:41 |
| n4nd0 | someone expecting :P? | 14:42 |
| pluskid | show the data :D | 14:43 |
| n4nd0 | http://snipt.org/uhOi1#expand | 14:44 |
| n4nd0 | there is still some space for improvement | 14:44 |
| n4nd0 | so it is promising | 14:44 |
| pluskid | wow | 14:44 |
| pluskid | tree construction plus querying | 14:44 |
| n4nd0 | yeah, everything there | 14:44 |
| pluskid | significantly outperforms qsort | 14:44 |
| pluskid | correctness of the results validated? | 14:45 |
| n4nd0 | not for this case I have timed | 14:45 |
| pluskid | anyway, it's super cool | 14:46 |
| n4nd0 | I have validated them for the non-integrated version, they were the same | 14:46 |
| pluskid | cool | 14:46 |
| n4nd0 | so I guess that they must remain, it is just the class used for the cover tree points what changes | 14:46 |
| pluskid | I think I should suggest some guys in my lab to try out cover tree in their projects :D | 14:46 |
| n4nd0 | :D | 14:46 |
| n4nd0 | I have still some work left to do | 14:47 |
| n4nd0 | I wanted to see some results fast | 14:47 |
| pluskid | sure | 14:47 |
| pluskid | encouraging! | 14:47 |
| n4nd0 | pluskid: I wanted to ask you by the way | 14:47 |
| n4nd0 | for you accuracy evaluation for KNN | 14:47 |
| pluskid | what do you mean? | 14:48 |
| n4nd0 | I think I could use it to check that everything is alright using the cover tree, right? | 14:48 |
| n4nd0 | let me see, maybe I am not using the right words | 14:48 |
| pluskid | I can't quite catch your meaning | 14:48 |
| n4nd0 | I don't really remember the exact words | 14:48 |
| n4nd0 | the first patch you did for shogun | 14:48 |
| pluskid | accuracy evaluation? | 14:49 |
| n4nd0 | yeah | 14:49 |
| n4nd0 | then it is what I said ;) | 14:49 |
| pluskid | yes | 14:49 |
| n4nd0 | is that something that can be used to check if the results given by KNN are correct? | 14:49 |
| pluskid | why not simply comparing the two results? | 14:50 |
| pluskid | covertree and qsort | 14:50 |
| n4nd0 | yeah sure | 14:50 |
| n4nd0 | that's the way I do it | 14:50 |
| n4nd0 | I just wondered if your patch was something "more profesional" to do this | 14:50 |
| pluskid | if they are the same, the algorithm should be correct | 14:50 |
| pluskid | I don't think so | 14:50 |
| n4nd0 | ok | 14:50 |
| pluskid | my patch is for clustering | 14:50 |
| pluskid | here is classification | 14:50 |
| n4nd0 | ok, my bad :S | 14:50 |
| pluskid | I think if two algorithms are the same, they should give the same accuracy | 14:51 |
| pluskid | but when they give the same accuracy, they are not necessarily the same :p | 14:51 |
| sonne|work | n4nd0: buy you can of course use any of the other evaluation modules that where made for clustering :D | 14:51 |
| n4nd0 | sonne|work: what do you think about the result? | 14:51 |
| sonne|work | very lovely :) | 14:52 |
| n4nd0 | sonne|work: but we can make it better | 14:52 |
| sonne|work | that is factor 4 now right? | 14:52 |
| n4nd0 | sonne|work: yeah | 14:52 |
| sonne|work | hmmhh wasn't knn even using multiple threads? | 14:52 |
| n4nd0 | I have not configured anything for threads | 14:53 |
| n4nd0 | so I think it is just with one | 14:53 |
| n4nd0 | the cover tree admits an heuristic to compute the distance | 14:54 |
| n4nd0 | there is an upper bound | 14:54 |
| n4nd0 | while computing the distance, if the intermediate result is already higher than this upper bound, one can cut the comptuations | 14:54 |
| n4nd0 | computations, sorry | 14:54 |
| n4nd0 | right now I am not doing that, I am just using the method distance in CDistance | 14:55 |
| n4nd0 | sonne|work: what about including in CDistance this distance computation with the upper bound? | 14:55 |
| sonne|work | n4nd0: feel free... | 14:55 |
| n4nd0 | sonne|work: cool | 14:55 |
| n4nd0 | I have still some time to have fun with this :D | 14:56 |
| n4nd0 | I will keep you update | 14:56 |
| sonne|work | it is actually not so easy | 14:56 |
| n4nd0 | sonne|work: why? | 14:56 |
| sonne|work | you would need to modify *every* distance function | 14:56 |
| n4nd0 | my idea was | 14:56 |
| n4nd0 | just to define it in Euclidian | 14:56 |
| n4nd0 | do people use KNN with other than that? | 14:56 |
| sonne|work | to stop doing computations once a certain distance is reached | 14:57 |
| sonne|work | probably | 14:57 |
| sonne|work | but agreed euclidian is most important | 14:57 |
| n4nd0 | I can include the heuristic in Euclidian for the moment | 14:58 |
| n4nd0 | for the others it would work just fine | 14:58 |

| pluskid | browse irc log ;) | 15:39 |
| sonne|work | gsomix: ahh 9 but we will return 1 | 15:41 |
| sonne|work | so 8 | 15:41 |
| sonne|work | which is still *a lot* | 15:41 |
| gsomix | sonne|work, is it the final decision? or should google make sure that shogun could have 8 students? | 15:45 |

| wiking | sonne|work: ? | 16:15 |
| sonne|work | can happen for noise data that just outputting a constant is better | 16:15 |
| wiking | mmm | 16:16 |
| wiking | but libsvm works fine that's the strange thing | 16:16 |

| mohataher | blackburn1 : I have just looked up the class, seems like I didn't find any functions equivalent to Diag(k), do you know the name of the function in Math.h ? | 20:51 |
| blackburn1 | mohataher: create_diagonal_matrix | 20:52 |
| mohataher | Is it added recently ? my version doesn't have this function, I will update my version and get back to you if I needed. Thanks | 20:57 |
| blackburn1 | mohataher: depends how old is your version ;) | 21:00 |

| wiking | blackburn1: here? | 22:44 |
| blackburn1 | da | 22:44 |
| wiking | cool | 22:44 |
| wiking | so whoever made gmm is around? | 22:45 |
| wiking | Alesis Novik | 22:45 |
| blackburn1 | no, he is doing phd in england and seems to be pretty busy | 22:45 |
| wiking | i was wondering if anybody would mind if it would be possible that u could preset the kmeans clusters | 22:45 |
| wiking | when you want to do gmm | 22:45 |
| blackburn1 | kind of warm start? | 22:46 |
| wiking | yep | 22:46 |
| wiking | e.g. u already have a preknowledge about the clusters. | 22:46 |
| blackburn1 | I don't mind if you do that ;) | 22:46 |
| wiking | ok | 22:47 |
| wiking | since now i'm testing gmm | 22:47 |
| wiking | on a very small dataset | 22:47 |
| wiking | and it's horribly slow | 22:47 |
| wiking | and as a matter of fact i do have the cluster centers from kmeans... | 22:48 |
| wiking | so i thought maybe it'd be good to save some time.. | 22:48 |
| wiking | but first i'll add some debugging code to gmm | 22:48 |
| wiking | and dtrace it or something | 22:49 |
| wiking | to see where goes the most calc | 22:49 |
| wiking | nyiha | 22:52 |
| wiking | most of the cpu time is used by dlasr | 22:52 |
| wiking | which is basically max_likelihood calc | 22:56 |
| blackburn1 | dlasr?? | 22:58 |
| wiking | it's from lapack | 22:58 |
| blackburn1 | yes I know that function | 23:00 |
| blackburn1 | I mean I am surprised ;) | 23:00 |
