Mlpack

2013-02-08
* Force minimum Armadillo version to 2.4.2.

* Better output of class types to streams; a class with a ToString() method
implemented can be sent to a stream with operator<<.

* Change return type of GMM::Estimate() to double (257).

* Style fixes for k-means and RADICAL.

* Handle size_t support correctly with Armadillo 3.6.2 (258).

* Add locality-sensitive hashing (LSH), found in src/mlpack/methods/lsh/.

* Better tests for SGD (stochastic gradient descent) and NCA (neighborhood
components analysis).

* Remove internal sparse matrix support because Armadillo 3.4.0 now includes
it. When using Armadillo versions older than 3.4.0, sparse matrix support
is not available.

* NCA (neighborhood components analysis) now support an arbitrary optimizer
(245), including stochastic gradient descent (249).

2012-08-15
* Added density estimation trees, found in src/mlpack/methods/det/.

* Added non-negative matrix factorization, found in src/mlpack/methods/nmf/.

* Added experimental cover tree implementation, found in
src/mlpack/core/tree/cover_tree/ (157).

* Better reporting of boost::program_options errors (225).

* Fix for timers on Windows (212, 211).

* Fix for allknn and allkfn output (204).

* Sparse coding dictionary initialization is now a template parameter (220).

2012-03-03
* Added kernel principal components analysis (kernel PCA), found in
src/mlpack/methods/kernel_pca/ (74).

* Fix for Lovasz-Theta AugLagrangian tests (182).

* Fixes for allknn output (185, 186).

* Added range search executable (192).

* Adapted citations in documentation to BibTeX; no citations in -h output
(195).

* Stop use of 'const char*' and prefer 'std::string' (176).

* Support seeds for random numbers (177).
