harshit_n4nd0: Hola !07:12
n4nd0harshit_: ey! how is it going?07:16
harshit_hey, my TSVM is almost ready but the problem is it takes too much time to converge07:17
harshit_whereas in svmlin time it doesn't takes that much time07:17
harshit_dont knw whats going on!!07:18
n4nd0harshit_: aham, so there must something different between both implementations right=?07:18
n4nd0mmmm about time of convergence, have you checked if they use a kind of tolerance value07:19
harshit_yeah, but I havnt changed that part much in shogun. that was already in shogun07:19
harshit_tolerance value ??07:19
n4nd0yeah, it was just an idea ...07:19
harshit_how to check that..?07:19
n4nd0looking at their code07:19
n4nd0anyhow, 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 more07:21
harshit_n4nd0: Hows your covertree07:21
n4nd0harshit_: I have to discuss with blackburn some details before starting to do the port07:25
n4nd0but it looks promising, it is very fast07:25
harshit_great .. Maybe after completing on KNN we can apply it on K-Means ,07:25

@sonney2kwe are currently investigating if we can handle all 9 or just 8 (as we requested)08:16
@sonney2ks/just/'just'/08:16
@sonney2kit is a huuuge number08:16
gsomixand good morning08:16
n4nd0gsomix: good morning08:16
n4nd0sonney2k: really, could it be a problem with the number of mentors?08:16
gsomix9?08:18
n4nd0gsomix: yeah08:19
gsomixtime to vodka08:19
n4nd0haha08:19
n4nd0c'mon isn't it like 10 around there? :P08:19
@sonney2kn4nd0, yes08:24
n4nd0that's not good08:24
@sonney2knot enough mentors08:24
@sonney2kwe had more ideas but for some ideas we did not get good proposals08:24
@sonney2kso these mentors won't mentor anything08:24
@sonney2kso in fact we are 7-8 mentors08:25
@sonney2kalright08:25
@sonney2khave to leave train08:25

sonne|workdoes anyone know which timezone pluskid is in?09:10
blackburn+809:10
sonne|workand heiko?09:10
blackburnI guess +1?09:11
n4nd0btw, if someone had any doubt, apart from being pretty fast, JL's cover tree gives correct results :)09:11
sonne|workheh09:11
sonne|worknice09:11
sonne|workn4nd0: so then it is even more clear that we want it :)09:11

sonne|workI've updated the website http://shogun-toolbox.org/10:18
sonne|worknot sure if a github banner is a good idea but hey I added it for now10:19
sonne|workalso removed broken links to tuebingen mpg10:19
blackburnyes it is10:19
n4nd0nice10:20
sonne|workahh but I got the link wrong10:20
blackburnsonne|work: we need new description I think10:20

sonne|worknot good10:51
blackburnsonne|work: may be some saturday evening would work10:51
blackburnhowever it is saturday heh10:52
pluskidcool to hear good news about 9 slots!10:52
sonne|workpluskid: you were UTC+8 right?10:52
pluskidGMT+8, is it the same as UTC+8?10:53
pluskidI'll google it10:53
blackburnyes10:53
pluskidsonne|work: yes, UTC+810:53
pluskidthe homepage github link point to http://github.com/you , is it intended?10:56
blackburnlol10:57
pluskidand the "you" actually has 16 followers10:57
pluskidthough no public repo10:57
pluskidPreviously I thought one mentor can be on multiple project, am I wrong?10:59
blackburnyou mean one person?11:00
pluskidyes11:00
blackburnyes that can be11:00
pluskidone person (as a mentor) can be in several projects(ideas), isn't it?11:01
pluskidI'm not sure11:01
sonne|workpluskid: yes11:01
sonne|workbut we try to restrict things11:01
sonne|workto be 1vs111:01
pluskidoh, that might be good for better quality11:02
sonne|workwhich means 7-8 slots is what we will actually use11:03
sonne|work(the downside of things)11:03

wikingany suggestion for metal earners?11:21
wikinghahahah metalearners  :)11:21
wikingstupid autocorrection11:21
wiking:>11:21
blackburnmetal earner lol11:21
blackburnwiking: what kind of metalearner?11:22
wikingwell anything that does a consensus in a good way between various ML classifications11:22
wikingbecause i have some good results with different features.... separately11:22
wikingbut when i add them together (even with combined kernel) the result degrades :)11:23
blackburnuh11:23
wikingso it's pretty annoying :)11:24
sonne|workwiking: then your normalization sucks11:24
wikingsonne|work: hahahahaha any suggestions ? :)11:25
pluskidblackburn: I find why LinearRidgeRegression is acting weird :)11:25
blackburnpluskid: why?11:25
pluskida small bug11:25
pluskidthe matrices are not initialized11:25
pluskidsimple fix :p11:25
sonne|work:)11:26
blackburnsonne|work: bad boy11:26
sonne|workwiking: well do you have the data or do I have it ...11:26
* sonne|work smacks sonney2k11:26
wiking:>>>11:26
* sonne|work luckily I am at work11:26
pluskid:>11:26
pluskidbtw I have some suggestions about CMath::twonorm and several related functions11:30
pluskidthe template function is returning the same type as the argument11:30
pluskidfor example, when you calculate twonorm for an int32_t vector11:30
pluskidyou get int32_t result, which would loss a lot of information11:31
wikingpluskid: yeah11:31
wikingah ok11:31
pluskidI suggest we use float64_t or something for all input types11:31
wikingi think in case of qnorm is not like that11:31
wikingafaik11:31
pluskidwhy?11:31
pluskidhave to leave for a while11:32
wikingmmm wait i'm mixing now11:32
pluskidcu later11:32
wikingah yeah11:32
wikingqnorm is like that as well11:32
wikingshouldn't be it should be something like pluskid says11:32
wikingthere's anyways an explicit casting there11:34
wikingwhen u return float64_t as class T11:34
sonne|workwiking: in case when we compute a float64_t anyways yes11:35
wikingman it's early here in my head11:35
wikingi meant implicit casting..11:35
wikingbut anyhow yeah it should always return something like float64_t even if the input vector is an int32_t11:35
sonne|workwiking: there is always a trade-off11:41
sonne|workthis can be wanted or not11:41
sonne|workwhen numbers are small the pure int32_t based compuation will use MMX and be very fast11:41
sonne|workand correct11:41
sonne|workif numbers become too big one needs the float64_t based variant11:42
sonne|workcomputation is slow but this is required for large numbers11:42
sonne|workso YMMV11:42
pluskidin our current implementation, float64_t is always used in computaion11:46
pluskidjust when we are returnining, it gets casted to T11:46
pluskidI think the trade-off sonne|work mentioned is true11:46
pluskidbut what we are discussing here is not that issue11:46
pluskidwe are thinking about whether we should return T or float64_t ?11:47

wikingwhat's a good kernel for sparse features apart from linear?14:37
n4nd0well guys I have the first timing results of JL cover tree used from shogun!14:41
n4nd0someone expecting :P?14:42
pluskidshow the data :D14:43
n4nd0http://snipt.org/uhOi1#expand14:44
n4nd0there is still some space for improvement14:44
n4nd0so it is promising14:44
pluskidwow14:44
pluskidtree construction plus querying14:44
n4nd0yeah, everything there14:44
pluskidsignificantly outperforms qsort14:44
pluskidcorrectness of the results validated?14:45
n4nd0not for this case I have timed14:45
pluskidanyway, it's super cool14:46
n4nd0I have validated them for the non-integrated version, they were the same14:46
pluskidcool14:46
n4nd0so I guess that they must remain, it is just the class used for the cover tree points what changes14:46
pluskidI think I should suggest some guys in my lab to try out cover tree in their projects :D14:46
n4nd0:D14:46
n4nd0I have still some work left to do14:47
n4nd0I wanted to see some results fast14:47
pluskidsure14:47
pluskidencouraging!14:47
n4nd0pluskid: I wanted to ask you by the way14:47
n4nd0for you accuracy evaluation for KNN14:47
pluskidwhat do you mean?14:48
n4nd0I think I could use it to check that everything is alright using the cover tree, right?14:48
n4nd0let me see, maybe I am not using the right words14:48
pluskidI can't quite catch your meaning14:48
n4nd0I don't really remember the exact words14:48
n4nd0the first patch you did for shogun14:48
pluskidaccuracy evaluation?14:49
n4nd0yeah14:49
n4nd0then it is what I said ;)14:49
pluskidyes14:49
n4nd0is that something that can be used to check if the results given by KNN are correct?14:49
pluskidwhy not simply comparing the two results?14:50
pluskidcovertree and qsort14:50
n4nd0yeah sure14:50
n4nd0that's the way I do it14:50
n4nd0I just wondered if your patch was something "more profesional" to do this14:50
pluskidif they are the same, the algorithm should be correct14:50
pluskidI don't think so14:50
n4nd0ok14:50
pluskidmy patch is for clustering14:50
pluskidhere is classification14:50
n4nd0ok, my bad :S14:50
pluskidI think if two algorithms are the same, they should give the same accuracy14:51
pluskidbut when they give the same accuracy, they are not necessarily the same :p14:51
sonne|workn4nd0: buy you can of course use any of the other evaluation modules that where made for clustering :D14:51
n4nd0sonne|work: what do you think about the result?14:51
sonne|workvery lovely :)14:52
n4nd0sonne|work: but we can make it better14:52
sonne|workthat is factor 4 now right?14:52
n4nd0sonne|work: yeah14:52
sonne|workhmmhh wasn't knn even using multiple threads?14:52
n4nd0I have not configured anything for threads14:53
n4nd0so I think it is just with one14:53
n4nd0the cover tree admits an heuristic to compute the distance14:54
n4nd0there is an upper bound14:54
n4nd0while computing the distance, if the intermediate result is already higher than this upper bound, one can cut the comptuations14:54
n4nd0computations, sorry14:54
n4nd0right now I am not doing that, I am just using the method distance in CDistance14:55
n4nd0sonne|work: what about including in CDistance this distance computation with the upper bound?14:55
sonne|workn4nd0: feel free...14:55
n4nd0sonne|work: cool14:55
n4nd0I have still some time to have fun with this :D14:56
n4nd0I will keep you update14:56
sonne|workit is actually not so easy14:56
n4nd0sonne|work: why?14:56
sonne|workyou would need to modify *every* distance function14:56
n4nd0my idea was14:56
n4nd0just to define it in Euclidian14:56
n4nd0do people use KNN with other than that?14:56
sonne|workto stop doing computations once a certain distance is reached14:57
sonne|workprobably14:57

wikingon a very small dataset22:47
wikingand it's horribly slow22:47
wikingand as a matter of fact i do have the cluster centers from kmeans...22:48
wikingso i thought maybe it'd be good to save some time..22:48
wikingbut first i'll add some debugging code to gmm22:48
wikingand dtrace it or something22:49
