Fix sanity check to actually check things correctly.
Add Estimate(const arma::mat&, const arma::vec&) so that this class can work as
a distribution for HMMs.
First simple test for GMM::Estimate(const arma::mat&, const arma::vec&).
Move .h to .hpp and .cc to .cpp.  We don't need dummy.cc anymore so it's
removed.
Compile LARS.
Big API changes for LARS.  Move things into the constructors; rename internal
variables.  Did a little commenting but I can't comment all that much.
changed CMakeLists.txt for radical so that compilation works in .../mlpack
added radical to CMakeLists.txt
Apparently an adversary swapped every occurrence that should be data.n_rows to data.n_cols and vice versa. This has been fixed, and LARS works once again
added LARS tests, but still need to make small changes before adding to CMake
added test cases for lars
Add GMM test case for training multivariate Gaussians in the setting where
probabilities of each observation are given.
It helps when you actually implement the stupid function instead of being an
idiot and thinking "well I'll just do it later but actually I'll forget that I
didn't do it and then not get to go to sleep instead".
Issue a warning when an empty GMM is created.
Test GMM::Random().
