| @sonney2k | van51, CR == code review | 05:47 |
| @sonney2k | van51, I guess git clean -dfx is your friend (will delete everything not in git!) and then configure/compile again | 05:48 |

| @sonney2k | moin foulwall_ | 06:13 |
| foulwall_ | hello sonney2k. | 06:13 |
| foulwall_ | almost done the visualization. | 06:13 |
| -!- nube [~rho@116.90.239.3] has quit [Quit: Leaving.] | 06:18 | |
| @sonney2k | foulwall_, for kernels you mean? | 06:18 |
| foulwall_ | sonney2k: yes. | 06:18 |
| -!- nube [~rho@116.90.239.3] has joined #shogun | 06:18 | |
| foulwall_ | sonney2k: I use dvalcarce's heatmap code. | 06:19 |
| @sonney2k | foulwall_, makes sense | 06:21 |
| @sonney2k | foulwall_, however, for classifiers we need heatmap + contour lines | 06:22 |
| foulwall_ | Do we need contour in kernel matrix? | 06:23 |
| @sonney2k | foulwall_, well it wouldn't hurt but it might be good enough for now | 06:24 |
| @sonney2k | foulwall_, basically what I have in mind is the heat map plus on top http://vis.lbl.gov/NERSC/Software/pvwave/docs/pvwavehtmlhelp/waveref/files/c2c-2-7.gif | 06:25 |
| foulwall_ | wow, thats cool | 06:25 |
| @sonney2k | but definitely a colorbar | 06:26 |
| @sonney2k | showing the range | 06:26 |
| foulwall_ | ok. | 06:27 |
| @sonney2k | foulwall_, look at e.g. svm_classification.py example | 06:27 |
| @sonney2k | or that http://shogun-toolbox.org/bigpicture/krr.png | 06:27 |
| foulwall_ | I'll try that, but I'll focus on the heatmap first. | 06:32 |

| foulwall_ | sonney2k: how about generate the image using gnuplot or plotting toolbox on the server? | 06:35 |
| foulwall_ | sonney2k: ignore that, I'll try to draw that in js. | 06:36 |
| @sonney2k | foulwall_, yeah that is what I did before... | 07:22 |
| @sonney2k | but d3 would be nicer... | 07:22 |
| foulwall_ | sonney2k: :) | 07:23 |
| van51 | hi | 07:43 |
| van51 | sonney2k: ok, i am re-compiling now | 07:43 |
| van51 | but I also pulled the code from upstream yesterday and installed that and had the same error | 07:44 |
| van51 | I did that in another directory | 07:44 |

| van51 | now I am getting an error | 07:59 |
| van51 | error: 'sg' undefined | 07:59 |
| @sonney2k | van51, well make install | 08:07 |
| van51 | sonney2k: yea I did | 08:07 |
| @sonney2k | van51, and yes I have it all running here so all failures are self inflicted :D | 08:07 |
| van51 | hehe | 08:07 |
| @sonney2k | foulwall_, btw lisitsyn has some very nice d3 visualizations for dimension reduction methods | 08:09 |
| foulwall_ | sonney2k: ok I'll ask him when he's online. | 08:10 |
| @sonney2k | foulwall_, have a look at http://tapkee.lisitsyn.me/ | 08:10 |
| @sonney2k | and then graphical examples | 08:10 |
| @sonney2k | and click on any of them. they are all interactive | 08:10 |
| @sonney2k | so mouse over will show you sth etc | 08:11 |
| foulwall_ | sonney2k: cool | 08:11 |
| @sonney2k | this is about as interactive is we should do it for everything | 08:11 |
| @sonney2k | e.g. allow people to mouse-hover over points of the curve | 08:11 |
| @sonney2k | and show the coordinates | 08:11 |
| @sonney2k | dragging a point -> retrain etc | 08:11 |
| foulwall_ | sonney2k: that's easy to add. | 08:12 |
| foulwall_ | sonney2k: just write some callback functions and connect them to the mouse event...wait me finish this kernel demo, I'll add them later. | 08:15 |
| @sonney2k | foulwall_, yeah | 08:17 |
| van51 | g2g run some errands argh | 08:24 |
| van51 | cu later :) | 08:24 |

| pickle27 | iglesiasg: how would you write code to subtract a vector from every row of a matrix using Eigen3? | 19:50 |
| pickle27 | iglesiasg: I've done it with loops but I'm wondering if there is a better way | 19:50 |
| @iglesiasg | pickle27: hey, yeah there is something to do that | 19:51 |
| @iglesiasg | pickle27: take a look to rwise and cwise | 19:51 |
| @iglesiasg | pickle27: let me check, I may have a minimal example doing sth similar | 19:51 |
| pickle27 | iglesiasg: okay thanks | 19:52 |
| @iglesiasg | pickle27: no I don't have one | 19:53 |
| @iglesiasg | but check if you can do something like | 19:53 |
| @iglesiasg | matrix.rowwise() - vector | 19:54 |

| @iglesiasg | pickle27: cool | 20:03 |
| pickle27 | iglesiasg: another quick one that you might be able to help with | 20:10 |
| pickle27 | iglesiasg: I need to replace any 0's with 1's in my matrix | 20:10 |
| pickle27 | iglesiasg: right now I'm looping but I'd like to try and use eigen3 | 20:10 |
| @iglesiasg | pickle27: what other values can that matrix have? | 20:15 |
| pickle27 | iglesiasg: its a matrix of standard deviation so positive values probably between 0 and 5 | 20:15 |
| @iglesiasg | I see | 20:16 |
| @iglesiasg | there must be some kind of find method or even some functionality via operators that return a Matrix::Index | 20:17 |
| @iglesiasg | I don't recall to have done it before though | 20:17 |
| pickle27 | iglesiasg: okay I'll look into it | 20:19 |

| lambday | HeikoS: hi :) | 20:47 |
| @HeikoS | lambday: hi! | 20:47 |
| @HeikoS | coming for you! :) | 20:47 |
| @HeikoS | how is it going? | 20:47 |
| lambday | I am thinking of getting the elliptic curve thing done asap | 20:48 |
| @lisitsyn | HeikoS: what about meeee | 20:48 |
| @HeikoS | lambday: yeah thats a good one to start since no thinking involved | 20:48 |
| @HeikoS | lisitsyn: oh yes, and of course for you :D | 20:48 |
| lambday | lol :P | 20:48 |
| lambday | HeikoS:yes.. | 20:48 |
| lambday | should we use arprec too in the project? | 20:49 |
| @HeikoS | doesnt krylstat do everything for you? | 20:49 |
| @HeikoS | or was it based on arprec | 20:50 |
| @HeikoS | forgot | 20:50 |
| lambday | HeikoS: no I mean, they use std:complex and double datatypes for few methods | 20:50 |
| lambday | and in other places, they redefined those methods using arprec | 20:50 |
| lambday | its for arbitrary precision stuff I guess | 20:50 |
| @HeikoS | I see | 20:50 |
| @HeikoS | so they just overload the std types and use that? | 20:50 |
| lambday | actually, the code is quite complicated | 20:51 |
| lambday | they have written everything separately | 20:51 |
| lambday | and redefined stuffs in many other places | 20:51 |
| @HeikoS | Erlend said that this would be almost copy/paste didnt he? | 20:51 |
| lambday | yes in few places they used overloading | 20:51 |
| -!- iglesiasg [~fjig@share-01.csc.kth.se] has quit [Quit: leaving] | 20:51 | |
| lambday | ummm... yes | 20:52 |
| lambday | but those methods, they haven't used in later parts | 20:52 |
| lambday | :-/ | 20:52 |
| @HeikoS | I see | 20:52 |
| @HeikoS | whats your suggestion then? | 20:52 |
| lambday | we can start with float64_t | 20:52 |
| pickle27 | lisitsyn: afraid lol, how so? | 20:52 |
| lambday | as of now | 20:52 |
| @HeikoS | lambday why would we need anything more precicse than float64_t | 20:53 |
| lambday | later we can use arprec if needed | 20:53 |
| lambday | I guess | 20:53 |
| @HeikoS | is this really the reason why they use arpec? | 20:53 |
| @lisitsyn | pickle27: I do not want to replace shogun by tapkee inside of shogun | 20:53 |
| @lisitsyn | :D | 20:53 |
| @HeikoS | maybe something else? | 20:53 |
| @lisitsyn | pickle27: we have to ask heiko and soeren what do they think | 20:53 |
| lambday | HeikoS: they use arprec for mp_real and mp_complex datatypes | 20:53 |
| lambday | nothing else (at least I haven't seen anything else) | 20:53 |
| lambday | we can use float64_t for real | 20:54 |
| @HeikoS | which is arbritary precision stuff right? | 20:54 |
| lambday | and std::complex | 20:54 |
| lambday | yes | 20:54 |
| @HeikoS | so the complex thing is the one that worries me | 20:54 |
| lambday | me too :D | 20:54 |
| @HeikoS | maybe there is something going on with arpec in there | 20:54 |
| pickle27 | lisitsyn: yeah that makes sense, okay. Just seems like Tapkee has more of that style of preprocessor than Shogun does | 20:54 |
| @HeikoS | for sure not for the float precision | 20:54 |
| @lisitsyn | HeikoS: lambday: guys sorry to interrupt you - just a quick question | 20:54 |
| @HeikoS | shoot | 20:54 |
| @lisitsyn | are you going to compute some eigenvalues | 20:54 |
| lambday | hmm? | 20:54 |
| @lisitsyn | like partial eigendecomposition | 20:55 |
| @HeikoS | lisitsyn: yes that might be necessary | 20:55 |
| @HeikoS | for example largest and smallest | 20:55 |
| lambday | yes | 20:55 |
| lambday | lancozos | 20:55 |
| @lisitsyn | HeikoS: alright, lets discuss possible approaches later then | 20:55 |
| @lisitsyn | HeikoS: we need to unify that stuff for tapkee and shogun | 20:55 |
| @HeikoS | lancozos is the only way I guess, but yes agreed on making things unified | 20:56 |
| @lisitsyn | lancozos?? | 20:56 |
| @lisitsyn | lanczos you mean? | 20:56 |
| lambday | yes my mistake :( | 20:56 |
| @HeikoS | copy/paste >:D | 20:56 |
| lambday | :D | 20:56 |
| @lisitsyn | well pure lanczos makes a little sense as there is arpack | 20:56 |
| @lisitsyn | which is implicitly restarted lanczos | 20:56 |
| @lisitsyn | HeikoS: http://www.ecs.umass.edu/~polizzi/feast/ | 20:57 |
| @HeikoS | lambday: you see, we should ask lisitsyn when it comes to this :) | 20:57 |
| @lisitsyn | HeikoS: this is quite interesting I think | 20:57 |
| lambday | HeikoS: :) | 20:57 |
| @HeikoS | lisitsyn: yes I want that | 20:57 |
| @lisitsyn | HeikoS: I imagine two cases | 20:57 |
| @lisitsyn | a) | 20:57 |
| @HeikoS | looks maintained and stuff | 20:57 |
| @lisitsyn | if we select some guy for dr he is going to do that | 20:58 |
| @HeikoS | what? | 20:58 |
| @lisitsyn | b) if we select no one for DR lambday may integrate that | 20:58 |
| @HeikoS | dr? | 20:58 |
| @lisitsyn | HeikoS: dim red | 20:58 |
| @HeikoS | I see | 20:58 |
| @HeikoS | yes good idea | 20:58 |
| @HeikoS | we need it anyway | 20:58 |
| lambday | hmm... okay I'll check this out | 20:59 |
| @HeikoS | but I want to talk to the other mentor first | 20:59 |
| @lisitsyn | HeikoS: alright sure | 20:59 |
| @HeikoS | he know a lot how to compute eigenvalues | 20:59 |
| @HeikoS | lambday: so for the std::complex replacement, maybe send an email to erlend and ask whether its fine to go with the not-overloaded standard types | 20:59 |
| @HeikoS | and if yes, go for it | 20:59 |
| @HeikoS | this should not involve any planning | 20:59 |
| @HeikoS | just a few functions of statistics | 20:59 |
| lambday | it should go in statistics? | 21:00 |
| @HeikoS | lambday: maybe, what do you have in mind? | 21:00 |
| lambday | HeikoS: umm... I was thinking of a separate class but that won't be necessary I think | 21:01 |
| lambday | statistics is good | 21:01 |
| @sonney2k | HeikoS, lisitsyn good evening gentlemen | 21:01 |
| @HeikoS | sonney2k: hi! | 21:01 |
| @HeikoS | lambday, so how many methods are we talking about? | 21:01 |
| @HeikoS | two or three? | 21:01 |
| lambday | three | 21:01 |
| @lisitsyn | sonney2k: abend | 21:01 |
| lambday | and few overloaded stuffs | 21:02 |
| @HeikoS | lambday I dont think this stuff will ever be used somewhere else, so Statistics should be fine | 21:02 |
| @HeikoS | we can always move it later | 21:02 |
| lambday | HeikoS: yup | 21:02 |
| @sonney2k | I just finished mowing the lawn so lisitsyn HeikoS lets discuss? | 21:02 |
| @HeikoS | ok good | 21:02 |
| lambday | oh and one more thing | 21:02 |
| lambday | (actually many more things) | 21:02 |
| @lisitsyn | sonney2k: just in public yes? :D | 21:02 |
| lambday | but | 21:02 |
| lambday | they used normal vectors for the sampling thing | 21:03 |
| @HeikoS | lambday go ahead | 21:03 |
| lambday | which they generate within the rational sampler .. | 21:03 |
| lambday | but | 21:03 |
| @HeikoS | sonney2k: give me a few minutes to catch up with lambday and to work through some PRs | 21:03 |
| lambday | they don't use that later too | 21:03 |
| lambday | rather rewritten those stuffs for probing vectors | 21:03 |
| lambday | so, I was thinking that vectors should be provided externally to the class | 21:03 |
| lambday | so that initially we can work with normal vectors later we can replace with probing vec stuff | 21:04 |
| @HeikoS | lambday this issues can easily be solbed with a class for the Hutchison estimator for the trace which is then overloaded | 21:04 |
| @HeikoS | so yes, start with std Gaussian samples | 21:04 |
| @HeikoS | but add the possibility to use other samplers instead | 21:04 |
| @HeikoS | like probing | 21:04 |
| lambday | HeikoS: yes... | 21:04 |
| lambday | hmm | 21:04 |
| @HeikoS | but also random [-1,1] vectors | 21:05 |
| lambday | yes... | 21:05 |
| @HeikoS | which have a lower variance than the Gaussian | 21:05 |
| @HeikoS | start with the simplest | 21:05 |
| lambday | okay | 21:05 |
| @sonney2k | lambday, can you discussion with HeikoS wait a bit (say <30mins?) - we have a meeting with him just now? | 21:05 |
| lambday | sonney2k: oh no problem :( sorry :( | 21:05 |
| @HeikoS | but dont use a flag for this, rather polymorphic thing | 21:05 |
| lambday | HeikoS: alright :) | 21:05 |
| @sonney2k | HeikoS, please ... | 21:06 |
| @HeikoS | sonney2k ok lets go | 21:06 |
| @sonney2k | thx | 21:06 |
| @HeikoS | lambday, we can continue in private chat | 21:06 |
| lambday | HeikoS: okie | 21:06 |
| @sonney2k | pickle27, hey there ! on you blas vs eigen3 thing | 21:12 |
| @sonney2k | pickle27, did you compile without optimizations perhaps? | 21:12 |
| pickle27 | pickle27: yeah? | 21:12 |
| pickle27 | pickle27: I can rebuild shogun and run it again | 21:13 |
| @sonney2k | pickle27, running w/o optimizations for eigen3 has a massive impact - but close to none for blas | 21:13 |
| @lisitsyn | haha! | 21:13 |
| @lisitsyn | without optimizations!?!?! | 21:14 |
| @lisitsyn | eigen?! | 21:14 |
| pickle27 | sonney2k: right, also the debugging flag was probably on too | 21:14 |
| @lisitsyn | ohoh | 21:14 |
| @lisitsyn | pickle27: you basically get like 17 calls in stack | 21:14 |
| pickle27 | sonney2k: lisitsyn does shogun build without eigen debug by default or do I need to set that | 21:14 |
| @lisitsyn | just to compute norm | 21:14 |
| @lisitsyn | pickle27: should build without debu | 21:15 |
| @lisitsyn | but -O3 is most important | 21:15 |
| @lisitsyn | pickle27: it makes no sense to compare blas with -O0 | 21:15 |
| @sonney2k | pickle27, if you did ./configure --disable-optimizations then -> slow | 21:15 |
| pickle27 | I'll rebuild and double check | 21:15 |
| @lisitsyn | eigen is even more slow | 21:15 |
| @lisitsyn | pickle27: it heavily uses metaprogramming | 21:15 |
| @lisitsyn | so with O0 nothing goes away | 21:16 |
| @sonney2k | pickle27, debugging flag doesn't hurt | 21:16 |
| @lisitsyn | with -O3 it goes down to a few SSE calls | 21:16 |
| @lisitsyn | so matters crazy a lot | 21:16 |
| pickle27 | lisitsyn: do I need to set anything for -03? | 21:17 |
| @lisitsyn | pickle27: no just do not put --disable-optimizations here | 21:17 |

| pickle27 | blas was 0.25 before but its not easy to re-test it | 21:34 |
| @lisitsyn | alright | 21:34 |
| @lisitsyn | pickle27: here we go then | 21:34 |

| @lisitsyn | vgorbati: hey, yes | 21:37 |
| pickle27 | lisitsyn: I've got it ifdef'd right now to default to eigen3 if both libs are present otherwise if only blas is there it will use blas. But it seemed the consensus was to keep just the eigen3 version | 21:37 |
| @sonney2k | pickle27, yes we intend to switch to eigen3 completely | 21:37 |
| @sonney2k | and drop all lapack/blas dependencies in the long term | 21:38 |
| vgorbati | lisitsyn: here' s the result of applying manifold sculpting to swissroll with small gaps https://www.dropbox.com/s/tdlpwup7fwsl8qi/manifoldSculptingEmbedding.png :) | 21:38 |
| @sonney2k | pickle27, eigen3 is much more readable and heavility developed (part of kde) | 21:38 |
| pickle27 | sonney2k: yeah I much prefer it :) | 21:38 |

| @sonney2k | van51, let me check | 21:43 |
| vgorbati | lisitsyn: ok, there's now also a small unit-test for manifold sculpting (smoke test), I have and idea of adding the test, that checks whether average neighbor distance is preserved - should I add it also, or skip for now? | 21:43 |
| @lisitsyn | vgorbati: no just skip for now | 21:44 |

| pickle27 | question about coding practice for shogun - in QDA code all loop counters (i,j,k) were defined at the beginning and then re-used throughout | 21:55 |
| pickle27 | is this the preferred way? is this actually any faster? | 21:55 |
| @lisitsyn | pickle27: not faster | 21:55 |
| pickle27 | lisitsyn: so can I define my loop counter inside my for loop then? | 21:56 |
| @lisitsyn | pickle27: yes that's the same | 21:56 |
| pickle27 | lisitsyn: and style wise that is okay with you guys? | 21:56 |
| @lisitsyn | pickle27: yes totally | 21:57 |
| pickle27 | lisitsyn: okay, I personally think it easier to read that way | 21:57 |
| @sonney2k | pickle27, my rule is to define variables at the lates possible moment | 21:58 |
| @sonney2k | otherwise it is too hard to figure out when the variable is used | 21:59 |
| pickle27 | okay right on, just doing some clean up stuff in mclda | 21:59 |

| van51 | sonney2k: yeap | 22:16 |
| pickle27 | sonney2k: I pushed a final version of MCLDA with Eigen3 and a unit test, let me know what you think it might be ready to merge | 22:16 |
| @HeikoS | lisitsyn: so there is a PR on this right | 22:16 |
| @sonney2k | HeikoS, lisitsyn btw I was analyzing memory consumption on one of our servers at work today | 22:16 |
| @HeikoS | and? | 22:17 |
| @sonney2k | and guess what I could come up with a 100% reliable predictor for non-weekdays / weekdays | 22:17 |
| @lisitsyn | HeikoS: ahhhhhh | 22:17 |
| @lisitsyn | I didn't know | 22:17 |
| @sonney2k | just based on memory consumption | 22:17 |
| @lisitsyn | :D | 22:17 |
| @HeikoS | sonney2k, haha thats cool | 22:17 |
| @HeikoS | how? | 22:17 |
| @HeikoS | whats with travis? | 22:18 |
| @HeikoS | cannot see certain pages | 22:18 |
| @sonney2k | well you know traffic is a lot less on non-weekdays/in holiday season | 22:18 |

| @sonney2k | van51, alright then lets bite the apple | 22:18 |
| @HeikoS | I like my weekends :) | 22:19 |
| @sonney2k | van51, the code is really much easier w/ arrays... | 22:21 |

| @sonney2k | van51, ohh it could be a dynarray issue - you call insert_element and that might not work for appending an element to the end | 23:45 |
| -!- mode/#shogun [+o iglesiasg] by ChanServ | 23:46 | |
| @sonney2k | van51, maybe just create a minimal test/example for jsut dynarray to validate that | 23:46 |
| @sonney2k | then it is also easy to fix | 23:46 |
| van51 | sonney2k: I think I had tested it | 23:46 |
| van51 | but let me do one now | 23:46 |
| @sonney2k | van51, you don't really need insert_element with dynarray | 23:47 |
| @sonney2k | just always call set_element | 23:47 |
| @sonney2k | it will grow everything automatically | 23:47 |
| @sonney2k | and we certainly need no insert* for the kernel stuff | 23:47 |
| @sonney2k | all we want is to extend the list of kernels - oh well you never know | 23:48 |
| van51 | sonney2k: set_element wouldn't replace the object at that index though? | 23:48 |
| @sonney2k | it would | 23:48 |
| @sonney2k | van51, it is just array[i] = obj | 23:48 |
| @sonney2k | but with growing array | 23:48 |
| @iglesiasg | sonney2k, van51 : hey guys | 23:50 |
| @iglesiasg | let me join you in the conversation | 23:50 |
| @sonney2k | iglesiasg, evening! | 23:50 |
| van51 | hi | 23:50 |
| @iglesiasg | I think a method like insert_element is a good idea to have | 23:50 |
| @iglesiasg | I think it makes sense to have a method that allows you put elements without the need of giving the index where to put them explicitly | 23:50 |
| @lisitsyn | push_back please | 23:51 |
| @iglesiasg | yeah, exactly | 23:51 |
| @sonney2k | iglesiasg, what should insert_element do when you give it an index too above anything | 23:51 |
| @sonney2k | lisitsyn, we have that | 23:51 |
| @lisitsyn | sonney2k: what is insert_element then | 23:51 |
| @lisitsyn | ahhhh | 23:51 |
| @lisitsyn | index based insert? | 23:51 |
| @sonney2k | yes | 23:51 |
| @iglesiasg | ah I see | 23:51 |
| @lisitsyn | then please call it insert | 23:52 |
| @lisitsyn | not insert_element or anything | 23:52 |
| @lisitsyn | sonney2k: how's your vim setup, is it working nice? | 23:52 |
| @sonney2k | lisitsyn, it is all long there | 23:53 |
| @lisitsyn | long like? | 23:53 |
| @sonney2k | lisitsyn, re vim not really using it | 23:53 |
| @sonney2k | but it works yes | 23:53 |
| @sonney2k | better than before | 23:53 |
| @lisitsyn | sonney2k: much better than before yes | 23:53 |
| @lisitsyn | sonney2k: due to no stl it is really fast in shogun | 23:54 |
| @lisitsyn | a bit slower in tapkee with eigen+stl | 23:54 |
| @sonney2k | well you are hardcore using templates etc | 23:54 |
| @lisitsyn | sonney2k: yeah some mpl | 23:54 |
| @sonney2k | I think dynarray dates back to 1999 or even before | 23:55 |
| @lisitsyn | sonney2k: oldschool flava | 23:56 |
| @lisitsyn | sonney2k: okay I think we need to speed up compilation now | 23:57 |
| @lisitsyn | sonney2k: btw no templates compare to swig | 23:58 |
| @sonney2k | lisitsyn, swig is only slow due to our %template stuff | 23:58 |
| @lisitsyn | I think even boost is faster to handle | 23:58 |
| @lisitsyn | than swig | 23:58 |
| @iglesiasg | speed up compilation sounds great hehe | 23:59 |
| @lisitsyn | sonney2k: we should get rid of it then | 23:59 |
| @sonney2k | mission impossible if we don't want to hack swig | 23:59 |
| @sonney2k | lisitsyn, how? I don't see it | 23:59 |
| @lisitsyn | sonney2k: me neither but I didn't think hard yet! | 23:59 |
