06:54 < ssk99> Hi guys, one of my unit tests is failing while building with azure. However, the test passes locally. Does anyone have any idea why this might happen?

06:57 < chopper_inbound[> ssk99: Can you provide the reference/link of failed build.

07:00 < ssk99> Ah sorry, never mind. The test fails locally too. Was using a previous version of the build which is why it passed locally. Thanks for the quick reply chopper_inbound[

07:12 < PrinceGuptaGitte> Hi @zoq, thanks for the review of PR #2184 . I have made changes as you have suggested along with some other pedantic style fixes. Please review it when you get time. Thanks.

09:16 < jeffin143[m]> Zoq : is there any callback for lbfgs written ???

09:16 < jeffin143[m]> Since progressbar couldn't be used

12:55 < metahost> zoq: Marcus I have added an example for the method I proposed. Please have a look when you can! :)

13:44 < Param-29Gitter[m> Hello, I wanted to know what is second parameter in constructor of arma::vec in gini gain. For example arma::vec counts(countSpace.memptr(), numClasses, false, true);

14:28 < PrinceGuptaGitte> Hi @Param-29 `arma::vec counts(countSpace.memptr(), numClasses, false, true);` This constructs a vector object that uses data at the memory location: `countSpace.memptr()`, numClasses determines the number of elements to take from that memory location. Third agrument determines whether this memory will be copied or not and last argument tell whether the size can change or not.

14:28 < PrinceGuptaGitte> So in your example your making arma::vec object from memory at location countSpace.memptr() with no. of elements = numClasses. It's not making a copy of that memory and you can't change the size of vector.

14:28 < PrinceGuptaGitte> I hope this clarifies your query.

14:39 < Param-29Gitter[m> Yes it did. Thank you :)

14:49 < PrinceGuptaGitte> Hi @kartikdutt18 I've implemented SQNL function as well, for issue #2181. Please have a look when you get time.

16:04 < kartikdutt18Gitt> Hi @prince776, I will take a look. Thanks.

17:02 < sailor[m]> Hi there. I am Joel Joseph. I code in python/c++ and have experience working on Deep Learning projects. Interested in contributing to the Reinforcement Learning project. Also want to apply for GSoC 2020. excited to be part of the mlpack community! 🙂

17:04 < sailor[m]> (edited) ... 2020. excited to be part ... => ... 2020. I look forward to being part ...

17:24 < zoq> sailor[m]: Welcome, in case you have seen it already we have a special GSoC page: https://www.mlpack.org/gsoc.html

17:42 < Param-29Gitter[m> @kartikdutt18 @zoq @rcurtin I have tried to improve performace #2169 Please do have a look :)

17:56 < kartikdutt18Gitt> Hi @Param-29, could you make the link accessible, it's asking for permission. Thanks.

17:58 < Param-29Gitter[m> Yes. I have made it accessible...

18:06 < sailor[m]> zoq thanks

18:42 < zoq> jeffin143: The progress bar depends on batches, at least the current implementation requires batches, but it's possible to provide an implementation that works without batches as well.

18:42 < zoq> jeffin143: But to answer your question, StoreBestCoordinates should work with any optimizer.

20:51 < Nakul[m]> how do we configure Travis.yaml for latest boost.

20:52 < Nakul[m]> I have added latest ppa and then downloading but it doesn't seems to work.

21:12 < zoq> Nakul[m]: Do you have a link to the modification?

23:08 < zoq> Nakul[m]: Looks like the ppa only provides Ubuntu 19 packages?
