02:08 < rcurtin> alsc: sorry for the slow response---I am at NIPS this week, I'll take a closer look when I get home

02:08 < rcurtin> the conference goes from like 8am to 10pm every day, very hard to stay on top of things :(

17:01 < praveenojha33> How to begin with Machine Learning if I want to contribute for mlpack.

18:21 < gopalakr> how do I compile mlpack so that the commandline executable are multithreaded ? currently all my executables are running on single core

18:23 < alsc> rcurtin: no worries! I’m away anyways

18:25 < rcurtin> alsc: sounds good; it'll probably be next week sometime

18:26 < rcurtin> gopalakr: make sure your compiler has OpenMP support (although it probably does), but not all of the command-line programs support multithreaded execution

18:26 < rcurtin> another way would be to use OpenBLAS instead of ATLAS or BLAS or LAPACK as the underlying linear algebra library

18:26 < rcurtin> this can provide significant speedups because OpenBLAS is parallel; but you'll only see those speedups in the command-line programs if that particular command-line program uses linear algebra heavily

18:31 < gopalakr> right ok thanks.. what should I specifically change in compilation to let openMP be the dafault ?

18:32 < rcurtin> cmake should detect it automatically

18:32 < rcurtin> you can compile with 'VERBOSE=1 make' to ensure that the '-fopenmp' flag is being used when the compiler is being called

18:33 < gopalakr> ok thanks will do this..

18:33 < gopalakr> unrelated question, does linear_regression expect dimensions as columns and rows as samples ?

18:34 < rcurtin> yes, if you are loading from a csv or similar, that's the expected format

18:35 < gopalakr> ok tx

18:35 < rcurtin> http://mlpack.org/docs/mlpack-2.2.5/doxygen/formatdoc.html

18:36 < rcurtin> the first section has some more details that could be helpful

18:37 < gopalakr> thanks I was looking for this page and dint find it.. will bookmark it tx :)

18:40 < rcurtin> yeah, there are a list of tutorials: http://mlpack.org/docs/mlpack-2.2.5/doxygen/tutorials.html

18:40 < rcurtin> if you find any errors in them or think anything is unclear, please say something! then we can improve it :)

18:41 < gopalakr> wil do
