| lisitsyn | yeah something is b0rken here | 00:00 |
|---|---|---|
| thoralf | I already fixed it. | 00:00 |
| thoralf | I'll merge tomorrow. | 00:00 |
| thoralf | But everytime I try to do something MLish, this happens to me. | 00:01 |
| thoralf | Wrong results, debugging, pen-and-paper tests and realizing the numbers are wrong. | 00:01 |
| thoralf | (not my numbers) | 00:01 |
| lisitsyn | though I remember there was an assumption about that :) | 00:04 |

| thoralf | My patch includes a check for this assumption. | 00:10 |
| thoralf | Checking for is_sorted is cheap if you can do multiplication in O(n) then. ;) | 00:10 |

| lisitsyn | khalednasr: hey | 12:39 |
| khalednasr | lisitsyn, hey | 12:39 |
| lisitsyn | khalednasr: theo's benn pretty busy lately | 12:40 |
| lisitsyn | been* | 12:40 |
| lisitsyn | so we get a bit out of touch :D | 12:40 |
| lisitsyn | I wanted to ask you what is your plan | 12:40 |
| lisitsyn | HeikoS1: suggested that we can improve notebook a bit | 12:40 |
| lisitsyn | khalednasr: so we can discuss what can be improved maybe? | 12:42 |
| khalednasr | lisitsyn, I was going to implement dropout and max-norm regularization, but if you have any suggestions on the notebook, we could try to improve it first | 12:42 |
| lisitsyn | oh already dropout things | 12:42 |
| lisitsyn | cool | 12:42 |
| lisitsyn | ok it is pretty brief now | 12:43 |
| lisitsyn | khalednasr: may be we could visualize learned layers somehow? | 12:43 |
| lisitsyn | that would be super cool | 12:43 |
| lisitsyn | have you seen hinton diagram? | 12:44 |
| khalednasr | yeah | 12:44 |
| lisitsyn | http://wiki.scipy.org/Cookbook/Matplotlib/HintonDiagrams | 12:44 |
| khalednasr | but i'm not sure it would look very good | 12:44 |
| lisitsyn | why? | 12:44 |
| khalednasr | since the hidden layers are not sparse or pretrained or anything | 12:44 |
| lisitsyn | yeah you're probably right | 12:44 |
| lisitsyn | ok so we need convolution layer to have cool visualizations | 12:45 |
| khalednasr | it might be better with dropout though | 12:45 |
| lisitsyn | khalednasr: does dropout lead to some sparsity? | 12:45 |
| khalednasr | yeah | 12:46 |
| khalednasr | http://www.cs.toronto.edu/~nitish/msc_thesis.pdf | 12:47 |
| lisitsyn | khalednasr: what is probably missed in the notebook | 12:47 |
| lisitsyn | you create layers | 12:47 |
| lisitsyn | but no mention how do they interconnect | 12:47 |
| lisitsyn | btw is it always like all to all? | 12:48 |
| khalednasr | so far, yeah | 12:48 |
| khalednasr | I guess i should mention that in the documentation and notebook | 12:48 |
| lisitsyn | yeah probably | 12:48 |
| lisitsyn | okay if you find something that can explain the architecture of network you created | 12:49 |
| lisitsyn | that would be cool | 12:49 |
| lisitsyn | some simple plot that gives an idea how the network looks like | 12:49 |
| lisitsyn | next | 12:50 |
| lisitsyn | I am afraid it makes sense to explain that regularization is here because of overfitting and so on | 12:50 |
| lisitsyn | ah | 12:50 |
| lisitsyn | sorry :D | 12:50 |
| lisitsyn | ok then may be it makes sense | 12:50 |
| lisitsyn | to say why it helps to avoid overfitting | 12:50 |
| lisitsyn | maybe even learn a model w/o L2 | 12:51 |
| lisitsyn | it also makes sense to output how much time does it take (when rendered) | 12:51 |
| lisitsyn | and how many epochs or whatever | 12:51 |
| khalednasr | maybe after I do dropout, i can compare the performance of different regularization methods | 12:52 |
| lisitsyn | do you plan to extend this notebook? | 12:53 |
| lisitsyn | or another one for dropout? | 12:53 |
| khalednasr | I think it would be better to just extend this one | 12:53 |
| lisitsyn | alright | 12:54 |
| khalednasr | It's already pretty short | 12:54 |
| lisitsyn | khalednasr: okay and another point | 12:54 |
| lisitsyn | may be cross validation here would be better | 12:54 |
| lisitsyn | so we can really estimate how do they infer | 12:54 |
| lisitsyn | khalednasr: HeikoS1 wanted to give some comments too | 12:55 |
| lisitsyn | so we can improve it gradually | 12:55 |
| khalednasr | yeah sure | 12:55 |

| kislay|exams | thoralf, heya! | 22:26 |
| thoralf | Key! | 22:26 |
| thoralf | Hey K! | 22:26 |
| kislay|exams | thoralf, sorry about being slow. My end semester exams are a major overhead! | 22:26 |
| thoralf | kislay|exams: Oh, yes! You already told me, right? | 22:27 |
| kislay|exams | thoralf, yup. some time back. | 22:27 |
| thoralf | I already forgot, sorry. | 22:27 |
| thoralf | I was just checking all issues that didn't change for some time... | 22:28 |
| thoralf | Cleaning up. | 22:28 |
| kislay|exams | thoralf, no problems. I will try to squeeze in as much as I can do in the meanwhile :) | 22:28 |
| thoralf | kislay|exams: Do your exams first and ignore me. | 22:28 |
| kislay|exams | thoralf, haha | 22:28 |
| thoralf | :D | 22:28 |
| kislay|exams | thoralf, thanks a lot. | 22:29 |
| thoralf | Treat me as the cleaning guy wandering through the building at night... :D | 22:30 |
| kislay|exams | thoralf, man! those people make me scared! | 22:30 |
| thoralf | See! | 22:31 |

| kislay|exams | thoralf, You know as a matter of coincidence, I mentioned issue 2054 in my proposal back when a new guy got agitated over the difficulties in the irc and then you created this. :D | 22:35 |

| @wiking | request for access if u r core developer | 23:08 |
| thoralf | Cool. | 23:08 |
| @wiking | although it needs some more tunning | 23:09 |
| thoralf | 877 defects | 23:14 |
| @wiking | yep some of them are FP | 23:15 |
| @wiking | the project settings should be fixed a bit in order to avoid FPs when SG_ERROR is being called | 23:16 |
| thoralf | Looks like they built a GUI around clang. | 23:20 |

| @wiking | thoralf: notonly | 23:21 |
| @wiking | thoralf: their static analysis is a bit more sophisticated | 23:21 |
| lisitsyn | wiking: finally! | 23:25 |
| lisitsyn | wiking: begged you for more rights | 23:25 |
| thoralf | Hmm. I don't understand 26258 | 23:27 |
| lisitsyn | thoralf: wiking: there is some pretty ok project for benchmarks in C++ | 23:27 |
| lisitsyn | https://github.com/nickbruun/hayai | 23:27 |
| lisitsyn | but the author is not really interested | 23:28 |
| lisitsyn | (looks like) | 23:28 |
| lisitsyn | I can fork and take it over to be used in shogun | 23:29 |
| lisitsyn | what are your thoughts? | 23:29 |
| thoralf | lisitsyn: Nice. | 23:31 |
| thoralf | lisitsyn: Do you have ideas what to benchmark? | 23:31 |
| lisitsyn | thoralf: we can benchmark a lot of things but no I have nothing concrete yet | 23:32 |
| lisitsyn | the thing is that I was searching | 23:32 |
| lisitsyn | how can we do that | 23:33 |
| lisitsyn | and there is basically nothing mature in this sense | 23:33 |
| lisitsyn | wiking: 331K LoC | 23:40 |
| lisitsyn | :D | 23:40 |
| lisitsyn | scary shit | 23:40 |

| thoralf | Pong. | 23:43 |
| lisitsyn | thoralf: it seems we didn't have you around | 23:44 |
| lisitsyn | when we wanted to try ourselves on kaggle | 23:44 |
| lisitsyn | thoralf: want to participate? | 23:44 |
| lisitsyn | we lack activity though | 23:44 |
| thoralf | What is kaggle? | 23:45 |
| lisitsyn | thoralf: really? :D | 23:45 |

| thoralf | Is it a competition? | 23:47 |
| lisitsyn | thoralf: competition platform | 23:47 |
| lisitsyn | I'd say | 23:47 |
| lisitsyn | but yeah we wanted to participate in a competition | 23:47 |
| lisitsyn | wiking: ping | 23:48 |
| lisitsyn | lambday: ping! | 23:49 |
| lisitsyn | :D | 23:49 |
| lambday | lisitsyn: pong | 23:50 |
| lisitsyn | lambday: I am just curious how loaded are you now | 23:50 |
| lambday | lisitsyn: right now? :D | 23:50 |
| lisitsyn | lambday: not | 23:50 |
| lisitsyn | in general | 23:50 |
| thoralf | lisitsyn: Aaah! Don't know what to do first. GSoC, coverity, ...?!?! | 23:50 |
| thoralf | Need 10h more per day! | 23:51 |
| lisitsyn | thoralf: vodka! | 23:51 |
| lisitsyn | lambday: I am asking because I have some slow progress on my prototype of 'brand new' parameters framework | 23:51 |
| lambday | lisitsyn: not very much.. will have to work on gsoc thing that me and heiko discussed | 23:52 |
| lambday | brand new parameter framework? | 23:52 |
| lisitsyn | lambday: well remember I wanted to replace everything | 23:52 |
| lisitsyn | plugins + parameters | 23:52 |
| lisitsyn | they are tied together | 23:52 |
| lambday | oh yes | 23:52 |
| lambday | you yourself are working on that? | 23:52 |
| lisitsyn | yes | 23:52 |
| lambday | cool! | 23:53 |
| lambday | umm what can I do to help? | 23:53 |
| lisitsyn | lambday: well I can create issues | 23:53 |
| lisitsyn | if I am working solely I don't issues | 23:53 |
| lisitsyn | need* | 23:53 |
| lisitsyn | :D | 23:53 |
| lambday | hehe | 23:53 |
| lambday | issues are good :D | 23:53 |
| lisitsyn | otherwise we could find something | 23:53 |
| lambday | lisitsyn: btw I remember about plugins but can't recall how parameter framework is tied up with that | 23:54 |
| lisitsyn | lambday: okay say your plugin has new parameter | 23:54 |
| lisitsyn | how do you set/get it | 23:54 |
| lambday | hmm | 23:55 |
| lambday | I should check out your poc implementation for this | 23:55 |
| lisitsyn | lambday: that's mostly it :D | 23:55 |
| lisitsyn | lambday: okay basic concept | 23:55 |
| lisitsyn | is every parameter has tag | 23:55 |
| lisitsyn | tag is an instance of Tag | 23:55 |
| lisitsyn | by tag you can set/get values | 23:55 |
| lambday | okies | 23:56 |
| lisitsyn | tag is templated so you it is typesafe | 23:56 |
| lisitsyn | Tag<int> | 23:56 |
| lisitsyn | you can't do | 23:56 |
| lisitsyn | get(Tag<int> tag) | 23:56 |
| lisitsyn | and get anything else than int | 23:56 |
| lambday | alrighty | 23:56 |
| lisitsyn | set(Tag<int> tag, int value) is the only available method as well | 23:56 |
| lisitsyn | so typesafety thing is solved | 23:56 |
| lisitsyn | lambday: about plugins | 23:58 |
| lisitsyn | lambday: each plugin exports a method | 23:58 |
| lisitsyn | that returns its manifest | 23:58 |
| lisitsyn | manifest is a collection of Class instances | 23:58 |
| lisitsyn | Class<T> | 23:58 |
| lisitsyn | Class<SVM> is some class that inherits SVM | 23:58 |
| lisitsyn | it can spawn its instance as SVM | 23:59 |
| lambday | aha! | 23:59 |
| lisitsyn | this is how I want to resolve plugin problem | 23:59 |
| lisitsyn | we declare base classes | 23:59 |
| lisitsyn | so basically we can't add new 'functionality' | 23:59 |
