11:15 < ShikharJ> rcurtin: The current lmnn_test.cpp/LMNNLowRankAccuracyTest seems to have the test statement commented out. Was this done on purpose?
12:15 < rcurtin> at the time yes, but I was working on a fix for it
12:15 < ShikharJ> rcurtin: Ah, I see :)

13:50 < wenhao> Hi guys I'm back from Europe:)
13:51 < Atharva> wenhao: Where all did you go?
13:53 < wenhao> I first went to ICML at Stockholm and attended some paper presentations on Preference and Rank Learning
13:53 < wenhao> Then we went to paris, lucern and rome
13:54 < Atharva> That's awesome!
13:55 < wenhao> A funny thing is that the last day we were at paris was the day france won the world cup
13:55 < Atharva> Oh! The environment must have been crazy there.
13:55 < wenhao> so a lot of people were celebrating at city paris
13:55 < wenhao> yes totally
13:58 < wenhao> we didn't plan to be a part of the celebration and we were on metro to our hotel, but the moving crowd in the metro forced us to triumph arch
14:00 < Atharva> wenhao: That must have been quite an experience, only a few tourists probably get to see the kind of Paris you saw.
14:00 < Atharva> wenhao: Otherwise, Paris is mostly calm.
14:02 < wenhao> Atharva: Yes! It was lucky for us to experience that just before we left paris. It was a lot of fun.
14:03 < wenhao> Atharva: Paris at it's calm days is also a nice place to stay and explore
14:03 < Atharva> wenhao: Yeah. How was Rome? I reallly wanted to go there on my trip but didn't have enough time.
14:03 < Atharva> wenhao: Yes it is.
14:04 < wenhao> Oh did you also go to europe?
14:04 < Atharva> Yes, earlier this summer :)
14:05 < wenhao> Atharva: Rome was nice too. A quite small city with lots of historic arts
14:06 < wenhao> Atharva: It was very hot when we were at rome
14:06 < Atharva> wenhao: Yeah it's historic attractions is the main reason I wanted to go.
14:07 < wenhao> Atharva: What cities did you go to?
14:08 < Atharva> I went to Paris, Amsterdam, Berlin, Prague, Budapest and Munich in that order
14:16 < wenhao> Atharva: wow a lot of cities. Sounds great.
14:18 < Atharva> wenhao: Yeah, it was really good.

19:44 < Atharva> Armadillo doesn't automatically cast from bool to int, does it?
19:45 < Atharva> I tried assigning a boolean matrix to an int or double matrix and it throws no match for ‘operator=’ (operand types are ‘arma::Mat<int>’ and ‘arma::enable_if2<true, const arma::mtGlue<long long unsigned int, arma::Mat<double>, arma::Mat<double>, arma .....
19:48 < zoq> arma::conv_to<arma::Mat<int> >::from(data); should work
19:51 < Atharva> zoq: It worked, thanks!
19:53 < zoq> Atharva: Great :)
19:53 < zoq> Atharva: Did you have time to run the experiments against RMSProp?
19:54 < Atharva> zoq: I haven't done it till now, I will start training in some time as I go to sleep.
19:55 < Atharva> Should I test both the convolutional as well as normal VAE?
19:56 < zoq> Atharva: Up to you, I guess if it works we can start another one.
19:57 < Atharva> zoq: Okay, I will test it on normal VAE then.
20:02 < ShikharJ> zoq: Just like Weight() returns the weights of the BinaryRBM, WeightCube() returns the weight of the SSRBM. Are we sure we wish to remove the WeightCube function?
20:03 -!- ImQ009 [~ImQ009@unaffiliated/imq009] has quit [Quit: Leaving]
20:07 < zoq> ShikharJ: I think we could derive the cube form the mat form, but perhaps it's a good idea to keep both, if we keep both do you think we could find another function name?
20:08 < ShikharJ> zoq: Neither functions are used inside the class anywhere, so I'm guessing Kris provided them for user convenience. I can remove both of them if you think if that could work as well.
20:10 < ShikharJ> zoq: We could have just one weight parameter which is a cube, and set its size during Reset() which would be dependent on the variant of RBM being used, though I'm not sure if I could alias a matrix from a cube or not.
20:11 < zoq> ShikharJ: That should work; I like the idea.
22:03 < ShikharJ> rcurtin: I'm seeing frequent failures in LMNNMainTest everytime a Travis build is initiated. I'm not sure if you're aware of it so just letting you know :)
22:10 < rcurtin> right, there is a PR open for it
