@wiking1700 euros13:10
@wiking:DDDDDDDDDDDD13:10
@wikingi'm gonna skip that one13:11
@HeikoSCaBa: we are organising a hackathon in Zurich13:11
@HeikoSwiking: lol13:12
CaBaHeikoS: neat13:12
lisitsynHeikoS: is it ok to just buy non-refundable ones now?13:12
@HeikoSlisitsyn: I did13:13
lisitsynok13:13
@HeikoSwe are fixed13:13
lisitsynalright13:13
lisitsynthey are cheaper13:13
@HeikoShow much?13:13
@HeikoSlisitsyn: I mean it is unlikely that something happens13:13
lisitsynlike 20%  no idea13:13
@HeikoSwe wont cancel if one person gets sick13:13

@HeikoSok gotta go13:13
lisitsynbuying now13:14
lisitsynok13:14
lisitsynsee ya13:14
@HeikoSwiking: re the input parser bug, you working on that or shall rahul or me have a go13:14
@HeikoS?13:14
@wikingHeikoS, i'm refactoring yes13:14
@wikingso will be fixed13:14
@HeikoSwiking: kk cool13:14
@HeikoSwiking: pushed rahul to get red of std::vector in the meantime13:14
@HeikoSso maybe that will coincide in timing13:15

@HeikoSlambday: jojo17:37
@HeikoShow are things?17:37
@lambdayHeikoS: yo17:37
@lambdayHeikoS: working on the tasks17:37
@lambdaynow that we have time, will clean up the code.. some of the things (as can be seen from the code itself) were done in a hurry.. resulted in messy and duplicate shits.. gotta place those in proper places..17:39
@lambdayotherwise maintaining it is gonna be tough as hell17:39
@lambday:/17:39
@lambdayinitial parts that I did are looking nice.. DataManager and all..17:40

@HeikoSlambday: yep yep17:53
@HeikoSlambday: absolutely agree17:53
@HeikoSlambday: we can pull that DataManager out into mainland Shogun once you are done17:53
@HeikoSthinking about how to integrate it and what other algos can use it, i.e. x-validation17:54
@HeikoSbut one thing after another17:54
@HeikoSthe std::vector replacements should be quick no?17:54
@lambdayHeikoS: yeah working on replacing those only17:55
@lambdayHeikoS: data manager is useful for (a) when there are multiple data sources (b) data needs to be processed block-wise (c) can mix and match different types, it works as a heterogenous container in practice17:56
@HeikoSyep i think we will find shogun algos for htat :)17:56
@lambdaycan mix streaming generators in one and dense matrix in another.. it will work17:57
@lambdayor even file streams (can be implemented)17:57
@lambdayI think the entire kernel family can be designed on top of it.. GaussianKernel shoudn't bother whether data is real dense or complex sparse.. as long as we can compute the dot, the same interface should work for all17:58
@lambdaywell, may not be the entire kernel family but some17:59
@HeikoSlambday: no I agree, we should start working with very generic representation of features17:59
@HeikoSthen we also dont have this float32, float64 thing anymore17:59
@HeikoSso I agree18:00
@HeikoSlambday: btw we are organising a hackathon in zurich18:00
@HeikoSin april18:00
@lambdayHeikoS: ah great! everyone is going?18:01

@HeikoSwhich works20:24
@HeikoSwe are missing a tiny thing before we can merge it back20:25

@sukeyPull Request #3654 "Fix CModelSelectionParameters::set_values()"  opened by lkuchenb - https://github.com/shogun-toolbox/shogun/pull/365420:25
CaBathere you go20:25
@HeikoSthanks!20:25
@HeikoSwill check20:25
@HeikoSCaBa: so moving thigns to header file?20:27
@HeikoSbecause otherwise you get linker errors?20:27
CaBano linker errors. it's a template.20:27
@HeikoSwhat happened before?20:27
@HeikoSjust not available20:27
CaBawell, you can't use it, compiler doesn't build anything into the .o file ;)20:27
@HeikoSyep so linker errors once you use it20:28
@HeikoSthanks!20:28
CaBaah, yes sure20:28

CaBasorry, though you were taling about shogun build linker errors ;)20:28
@HeikoSCaBa:  thanks for da patch20:31
CaBanp, thanks for the quick merge20:31
@HeikoSlambday: jo sitll there=?20:32
@lambdayHeikoS: yes20:33
@HeikoSlambday: how are things?20:33
@HeikoSlate? :D20:33
@lambdayHeikoS: yeah pretty.. been cooking... will have dinner now20:34
@HeikoShaha20:34
@lambdaywill send a patch before going to sleep20:34
@HeikoSIm off now20:35
@lambdayit's 01:00 at my place :P20:35
@HeikoSfrustrated as we just realised our proof strategy doesnt work20:35
@lambdaywhat are you working on?20:35
@HeikoSlambday: remember the kernel exp family?20:37
@lambdayHeikoS: yeah20:37
@HeikoSlambday: I wrote an approximation algorithm for that20:37
@HeikoSlambday: similar to the KRRNystrom20:38
@lambdayawesome20:38
@HeikoSand now we are trying to write a proof that shows how fast it converges20:38
@HeikoSpreferably with optimal convergence rates, i.e. "there is not faster algorithm"20:39
@HeikoSbut we realised that the way we approached this doesnt work20:39
@HeikoSso now back to more humble statements ;)20:39
@lambdayHeikoS: like a multiplicative optimality guarantee?20:39
@lambdaysome factor?20:39
@HeikoSno this is all asymptotics20:39
@HeikoSso all up to constant20:40
@HeikoSits more worst case20:40
@HeikoSso that you are guaranteed something20:40
@HeikoSin practice it can be faster20:40
@lambdayHeikoS: yeah getting a sense20:41
@HeikoS||f-f_0|| <= somefunctionof(n,\lambda, approximation_level, problem_hardness)20:42
@HeikoSlike that20:42
@HeikoSok gotta go20:42
@HeikoSenjoy your night hack!20:42
@HeikoSI might do one tomorrow20:42
@lambdayHeikoS: in my master's thesis, my task was to prove an optimality guarantee for an approximate submodular objective.. gave a multiplicative one..20:42
@lambdayHeikoS: alright20:43
@lambdayhope to know your stuffs soon.. cool for Shogun as well :)20:43
@lambdayHeikoS: see you :)20:43
