10:32 < ImQ009> Hm
10:32 < ImQ009> I've got a little problem whilst training my RNN. I get a crash in negative_log_likelihood_impl.hpp @ 39, because of currentTarget underflow
10:33 < ImQ009> target(i) is 0
10:39 < ImQ009> It seems to not like my labels being 0
10:39 < ImQ009> When I set them all to 1, it's fine
10:39 < ImQ009> It seems there's something I don't understand about the way I'm supposed to label my data..
10:41 < ImQ009> When I look in the example RNN code there's this label post-process thing, which adds 1 to all labels... Hmmm
10:46 < ImQ009> I don't think that's something I should be doing though. I tried it and I get the same kind of crash - out of bounds
11:23 < ImQ009> Okay, I think I got it, got what I got wrong
11:23 < ImQ009> I forgot I have to treat X and non-X as separate class
11:23 < ImQ009> Thus, I need separate rows for those in the labels
11:24 < ImQ009> And it seems I do have to add 1 to the labels, can't be 0, huh...
11:24 < ImQ009> Any hints on that, please?

14:19 < rcurtin> wow, I'll have to delete that spam from the log ...
14:21 < rcurtin> ImQ009: I think the best example code is in recurrent_network_test.cpp, have you taken a look at that?
14:24 < ImQ009> rcurtin, yes
14:25 < ImQ009> That's the example I was referring to
14:27 < ImQ009> Thing is, there are some pieces of code that example that aren't explained
14:27 < ImQ009> Like adding 1 to the labels
14:32 < ImQ009> rcurtin, at any rate, there's one thing that I'm very interested in getting to know: how should I go around to predicting a stream of incoming data? Can I just feed data as it comes or do I need to construct a dataset of Rho timesteps?

19:16 < dungeon_master> Hello, I want to know if a single file can be build in mlpack? Actually I'm writing a test for a binding and I have to compile the whole mlpack or mlpack_test code which consumes a lot of time as well as computational resources.
19:17 < dungeon_master> Moreover, I noticed that whenever I build the codebase inside Clion IDE it takes too much RAM and couldn't build ultimately but when I build the same through command line everything is build efficiently
