@wikingok next one is up15:06
vikram360It'd be awesome if you could please put the slides up. It'd be much easier to follow along with the speaker. But it's okay if it's going to be too much of a problem to put that up :)15:07

vikram360wiking : any particular reason? if this isn't the place for this discussion, let me know. I'm just curious.15:40
@wikingi think it's just a personal option15:41
vikram360so not technical reason?15:44
@wikingno not at all15:44
@wikingGP question time15:46
vikram360I should've done my reading about this but what are some of the things that SVM's are better at than GP's?15:47

vikram360what's the local time there?17:21
pickle27its 5:21 according to google17:22
pickle27i was trying to figure out whats up too17:22
pickle27can't tell if the dimension reduction talk is over or starting17:22
pickle27also all I hear is a buzz17:22
vikram360same here.17:22
pickle27well I guess we'll stay tuned17:23
vikram360Looks like other people in the audience are waiting for it too. So I guess it's safe to assume that it's yet to begin :)17:23
pickle27what browser slash OS are you using?17:23
vikram360I hope the audio feedback doesn't continue when it starts17:23
vikram360Win XP/FiF 2217:24
vikram360And you?17:24
pickle27linux and chrome17:24
vikram360I'm not a dinosaur, FYI. I'm using my home PC which, for my parents' convenience is still on XP.17:25
vikram360 I just thought I'd clear that up.17:25
pickle27okay we've got 2 very different setups giving the same result17:25
vikram360I hope tihs audio feedback doesn't persist when the talk starts17:26
pickle27yeah me too17:26
-!- pickle27 [] has quit [Quit: Leaving]17:26
vikram360wiking , lisitsyn : could you please check the audio source. There seems to be some sort of a buzz (sounds like feedback)17:27
-!- pickle27 [] has joined #shogun17:28
@wikingvikram360: we turned off audio17:29
pickle27so we can't really watch the stream then17:29
vikram360Oh, okay. You guys plan on turning it back on when the session starts, I hope?17:30
@wikingwithin seconds17:30
pickle27ahh kk17:30
@wikinglisitsyn: is talking now17:31
@wikingif u have problesm with the audio17:31
@wikinglet me knwo17:31
vikram360There's a bit of a buzz on there. pickle27 you hear it too?17:32
vikram360It's not too bad though.17:32
@wikingyeah unfortunately we have a little bit of static noise :(17:32
@wikingwe couldn't fix it17:32
thoralf_sonney2k: Some other usability issue is IDE (Eclipse, Netbeans, Slickedit).17:32
pickle27its not too bad17:33
thoralf_sonney2k: The current build configuration is hard to integrate into IDE workflows.17:33
thoralf_sonney2k: Especially that most of the code requires that you have run "(sudo) make install" after "make all".17:34
@sonney2kthoralf_, where are you ?17:35
vikram360pickle27 : Here're the slides to this talk:

van51gsomix_: hey20:03
gsomix_van51, hey.20:03
van51gsomix_: can I ask you something?20:03
van51gsomix_: I was using your LineReader before it was merged20:03
van51gsomix_: to read a binary file that had text delimited by \020:04
van51gsomix_: but after the merge it has stopped working20:04
van51gsomix_: actually it is reading stuff but it stops prematurely20:04
van51gsomix_: I had the same problem with using  basic c++ I/O20:04
van51gsomix_: do you have any suggestion? or could you tell me what did you change?20:04
gsomix_van51, hm. can you send me your code and text file? I'll check.20:05
van51gsomix_: give me a moment to cut a bit of the file because it's huge :P20:06
gsomix_>> before it was merged | hipster-programmer20:12
van51gsomix_: haha20:14
van51gsomix_: here is the file :
van51gsomix_: it's actually binary20:14
van51gsomix_: and here is my code20:14
gsomix_van51, ok.20:18
-!- gsomix_ is now known as gsomix20:18
van51gsomix: thx for offering to look at it20:19
van51gsomix: but don't spend too much time on it20:19
van51gsomix: I'm sure you have other stuff to do as well :)20:19
van51gsomix: I was just wondering if you could think of something20:19

gsomixvan51, hey. how many parts are delimited by \0 in your file?21:15
van51gsomix: in the one I send you I think there is only one \021:15
gsomixvan51, and where reading stops?21:17
van51gsomix: it stops at "<area shape="RECT" coords="7,86,110,100""21:17
-!- thoralf [~thoralf@] has quit [Ping timeout: 276 seconds]21:17
van51gsomix: while it should have stopped at a </html>21:17
gsomixvan51, it works fine for me. I just replace SG_SPRINT("%s\n") by for (bla_bla) { SG_SPRINT("%c"); }.21:20
gsomixdo I miss something?21:20
van51gsomix: give me a moment to check21:20
van51gsomix: hmm indeed21:21
van51gsomix: I was just getting a seg fault in the beginning and I assumed it was from there21:21
van51gsomix: and the print statement didn't help :)21:22
gsomixbtw can you use has_next_line() for checking? I found some bad behavior in my code - need to fix.21:23
van51gsomix: ok I'll use it21:24
van51gsomix: thanks for your time :)21:24
van51gsomix: what was the bad behavior btw?21:26
gsomixvan51, unlimited decrease the internal counter in CircularBuffer when you try read nothing. nevermind. :)21:27
gsomixjust use has_next_line, I'll fix this thing little late.21:27
van51gsomix: cool21:28
gsomix>> thanks for your time | now I need YOUR time. a little. I'm writing CSV reader now.21:29
gsomixhow do you think what's better solution: templated CSV reader class with SGVector<T> readVector() and SGMatrix<T> readMatrix() methods21:30
gsomixor not templated class with many methods like SGVector<int32_t> readIntVector(), SGVector<int64_t> readLongIntVector()...21:31
gsomixand so on21:31
van51gsomix: hmm21:31
van51gsomix: I think I would prefer the first one21:32
van51gsomix: is there a change the csv file could have vectors of different types?21:32
gsomixyeah, maybe. I still didn't figured out how work with it. btw quoting is pain with only DelimiterTokenizer.21:35
gsomixnow I want just write reader for one-typed csv files21:35
van51gsomix: what exactly is pain?21:36
van51gsomix: reading between quotes?21:36
gsomixI think I should split line with " delimiter first, and then analyze each token21:39
van51gsomix: you use multiple delimiters?21:40
van51gsomix: then repeated calls to get next_token wouldn't give you the thingy between quotes?21:42
gsomixthere are some exotic examples, like delimiters and \n between quotes, that shouldn't be delimiters because it's quoted.21:43
van51gsomix: aaah I see21:44
van51gsomix: yeah that would be an issue21:44
gsomixbut I don't really think this is common for ML data sets. need consult with sonney2k21:44
van51gsomix: I don't know about that, but if it's required I could add support for it in the delimiter class21:46
gsomixvan51, I don't think that it's really needed.21:46
gsomixvan51, ok, thanks for advice. I should continue my work.21:47
gsomixah, and cool video at the end!
van51gsomix: I hadn't even considered escaped delimiters21:48
van51gsomix: maybe it's something that needs to be supported21:48
van51gsomix: anyway, discuss it with sonney2k and let me know :)21:48
van51gsomix: nice vid :)21:50
gsomixyeah, SpaceX is great aerospace company. I would work in it, but I'm not rocket scientist, huh.21:54
van51gsomix: you could learn how to handle a camera :p21:54
