| mikeling | hey, why "./tests/unit/shogun-unit-test --gtest_filter=GaussianProcessRegression.apply_*" doesn't work for me even after I run make shogun-unit-test | 12:41 |
| mikeling | ok the unit-test works, but I have no idea what't the meaning of the error my got | 13:11 |
| mikeling | hi lisitsyn, could you give me some help on https://travis-ci.org/shogun-toolbox/shogun/jobs/197601158#L4013? I have no idea about this error | 13:11 |
| mikeling | and how could I debug my code when the ctest told me unit-KNN has SegFault? I use lldb on OS X | 13:13 |
| -!- nagdev [dce39546@gateway/web/freenode/ip.220.227.149.70] has joined #shogun | 14:08 | |
| @wiking | mikeling, still around? | 14:34 |
| mikeling | wiking: yep | 14:34 |
| @wiking | ok so | 14:34 |
| @wiking | how do you run your cmake on your machine? | 14:34 |
| mikeling | wiking: it's **cmake -DCMAKE_BUILD_TYPE=Debug -DENABLE_TESTING=ON -DBUILD_DASHBOARD_REPORTS=ON -DDEBUG=ON ../** | 14:35 |
| @wiking | ok | 14:35 |
| @wiking | you dont need DBUILD_DASHBOARD_REPORTS | 14:35 |
| @wiking | nor DDEBUG=ON | 14:35 |
| @wiking | but | 14:35 |
| @wiking | you should have | 14:35 |
| @wiking | -DBUILD_META_EXAMPLES=ON | 14:35 |
| @wiking | imo it's on by default by just in case | 14:35 |
| mikeling | wiking: ok, I will try it right now. Thank you for your help!:) | 14:37 |
| @wiking | and note that some some part of knn | 14:37 |
| mikeling | do you mean the error I got about knn unittest? could you tell me more specifically about that? | 14:40 |
| @wiking | ok so i was wondering if the falconn part might be using openmp | 14:41 |
| @wiking | that's why | 14:41 |
| @wiking | you might not be able to reproduce it on osx with clang compiler by defalt | 14:41 |
| @wiking | but i dont see any #pragma in the falconn code | 14:41 |
| @wiking | so that's not it | 14:41 |
| @wiking | so you should be able to reproduce | 14:41 |
| @wiking | locally | 14:42 |
| @wiking | btw if you run | 14:42 |
| @wiking | ctest | 14:42 |
| @wiking | everything is passing you? | 14:42 |
| @wiking | because for me it seems there are some serious errors in everyjob | 14:42 |
| @wiking | on travis | 14:42 |
| mikeling | wiking: yeah, if I just use ctest and everything works for me | 14:44 |
| @wiking | mmm | 14:44 |
| @wiking | you might be missing some libraries? | 14:44 |
| @wiking | hence some code is just not being compiled? | 14:45 |
| @wiking | i'm not so sure | 14:45 |
| @wiking | but in worst case | 14:45 |
| @wiking | you could fire up a docker image :) | 14:45 |
| @wiking | and check it yourself | 14:45 |
| @wiking | imo there's a quite good docker implementation on osx already | 14:45 |
| mikeling | wiking: oh, so let me use docker image and see what i can got. I'm not familiar with docker so it may every consuming before I got things right ;) | 14:49 |
| @wiking | well | 14:51 |
| @wiking | if you follow .travis.yml | 14:51 |
| @wiking | then you'll actually get what travis does | 14:51 |
| @wiking | locally | 14:51 |
| @wiking | actually | 15:01 |
| @wiking | if you figure that out | 15:01 |
| @wiking | could you write a couple of lines of markdown document | 15:01 |
| @wiking | how to do it | 15:01 |
| @wiking | i mean it's there | 15:01 |
| @wiking | just it'd be a good doc for everybody to share | 15:02 |
| @wiking | how to reproduce travis errors locally on your machine ;) | 15:02 |
| * wiking is being super lazy :P | 15:02 | |
| nagdev | wiking: I read up on all the work that has been done on the usual suspects project previously and I was thinking about working with KNN or neural nets. Do you know if anyone is already working on it? | 15:05 |
| @wiking | nagdev, mikeling is working on KNN atm | 15:12 |
| @wiking | i dont recall anybody working on nns | 15:12 |
| mikeling | wiking: nagdev I'm working on this issue actually :) https://github.com/shogun-toolbox/shogun/issues/3507 | 15:15 |
| mikeling | wiking: sure, I will write all the things down if I figure out all the things. :) | 15:15 |
| mikeling | sorry for the late reply, I just miss the message somehow | 15:15 |
| nagdev | mikeling: so can I just start working on it with you or will I need some background? | 15:16 |
| nagdev | I know KNNs in general | 15:16 |

| -!- abhinav [~abhinav@103.211.53.99] has quit [Client Quit] | 15:21 | |
| mikeling | nagdev: yeah sure, actually I had commit a PR for that issue(https://github.com/shogun-toolbox/shogun/pull/3608), but the SegFault stop me verify if all my code works | 15:22 |
| mikeling | it will be great appreciate if you can check that code and give me some feedback | 15:27 |
| nagdev | mikeling: Cool. Give me some time to read all the existing work and catch up. I'll start giving my inputs as soon as I'm done with that | 15:27 |
| nagdev | wiking: couple more things. Firstly, the PCA implementation is already significantly faster than other toolboxes. Why is PCA still in the list of algorithms to be improved? Are there any further changes that need to be made in it? | 15:30 |
| nagdev | Second, some of the algorithms listed in project list were already taken up in prev year's GSoC. Are they still not complete? | 15:31 |
| mikeling | nagdev: oh great! Thank you :) | 15:34 |
| mikeling | nagdev: BTW, are you going to apply GSoC this year? Which project you are interested in? if I may ask :) | 15:35 |
| @wiking | nagdev, mmm there's alway room for improvement :) | 15:38 |
| @wiking | i do not know actually in case of each and every model what needs to be improved | 15:38 |
| @wiking | but rest assured none of them is prefect :) | 15:38 |
| @wiking | just pick anything that is to your liking and nobody else if working on (you can figure this out from the open prs) | 15:39 |
| @wiking | or just do something that you find interesting | 15:39 |
| @wiking | and you reckon it would be a good feature to add | 15:39 |
| @wiking | and it's easy to add to shogun | 15:39 |
| @wiking | you do not need to necessarily stick to that list | 15:39 |
| @wiking | it's just giving u some ideas | 15:39 |
| @wiking | like for example we do not have a preprocessor | 15:39 |
| @wiking | that does one-hot encoding for a categorical variable | 15:40 |
| nagdev | wiking: Sure. I think I'll start working on KNN only and figure out if there is something else that I can work on as well | 15:48 |
| @wiking | mmm | 15:48 |
| @wiking | since mikeling is alrready working on knn | 15:48 |
| @wiking | i would really suggest you to pick something else | 15:48 |
| @wiking | otherwise it's inevitable that you'll end up doing double work | 15:49 |
| @wiking | and as we would like you to take something on your own to see how you handle things ..... dont get me wrong collaboration is very good but as well getting deep into some parts of the code alone is important | 15:50 |
| nagdev | yeah i understand | 15:50 |
| nagdev | is it ok if I just lurk around to see how he's working because I'm fairly new to open source and don't know much about how to go around doing things. That's why I wanted to work with someone to start off | 15:51 |
| @wiking | nagdev, mmm the point of entrance tasks are actually this | 15:52 |
| @wiking | they are small | 15:52 |
| nagdev | I'll just see how he's working (general direction and coding style) | 15:52 |
| nagdev | ok | 15:52 |
| @wiking | fairly easy to get you started | 15:52 |
| @wiking | and it's quite autonomous | 15:52 |
| @wiking | anyhow | 15:52 |
| @wiking | just pick anything from the entrance tasks | 15:53 |
| @wiking | try to fix it | 15:53 |
| @wiking | and send in a pr | 15:53 |
| @wiking | as soon as you send in a pr we can give you a hand | 15:53 |
| @wiking | tell you what is ok and what is wrong | 15:53 |
| @wiking | usually the first pr takes about 3-4-6 iterations | 15:53 |
| @wiking | till it gets actually merged | 15:53 |
| @wiking | there's really no better way to get started with this is to try and fail | 15:54 |
| @wiking | :) | 15:54 |
| nagdev | ok sure. I'll try out some tasks. | 15:54 |
| nagdev | mikeling: I'll only apply if shogun gets selected because afaik it is the only ML related project in the organization list. I'm mostly interested in projects which involve core ML implementation and improvement. | 15:57 |
| nagdev | So from the available list, usual suspects, real life problem solving and shogun extension are my preferred options | 15:58 |
| nagdev | Usual suspects seems to be the most likely in that. | 15:58 |
| nagdev | In that too, I would prefer to work on PCA, KNN or neural nets as I'm working on some papers to improve the algorithms and it'd be great to translate that into actual, functioning code | 16:01 |
| nagdev | wiking: the entrance task doesn't mean that I have to commit to the project right? | 16:06 |
| @wiking | what do you mean? | 16:07 |
| nagdev | If i try to work on a bug on a particular algo (say GP), I can still switch to some other project (like NN) later right? | 16:09 |
| @wiking | sure | 16:10 |
| @wiking | then entrance is just about | 16:10 |
| @wiking | seeing how can you contribute/code/interract etc | 16:10 |
| nagdev | so I was looking at https://github.com/shogun-toolbox/shogun/issues/3054 and https://github.com/shogun-toolbox/shogun/issues/3513 to start with. There has been some work in these already. Is it still fine if I start with one of these? | 16:14 |

| shogitter | (etotientz) are there no newcomer issues to solve at https://github.com/shogun-toolbox/shogun/issues?utf8=%E2%9C%93&q= | 21:21 |
| shogitter | (etotientz) I m interested in contributing here | 21:21 |
| shogitter | (etotientz) maybe relevant to gsoc this year | 21:21 |
