history and news
june 13, 2013 -- mlpack 1.0.6

• Minor bugfix so that FastMKS gets built.

may 1, 2013 -- mlpack 1.0.5

• Speedups of cover tree traversers (#243).
• Addition of rank-approximate nearest neighbors (RANN), found in src/mlpack/methods/rann/.
• Addition of fast exact max-kernel search (FastMKS), found in src/mlpack/methods/fastmks/.
• Fix for EM covariance estimation; this should improve GMM training time.
• More parameters for GMM estimation.
• Force GMM and GaussianDistribution covariance matrices to be positive definite, so that training converges much more often.
• Add parameter for the tolerance of the Baum-Welch algorithm for HMM training.
• Fix for compilation with clang compiler.
• Fix for k-furthest-neighbor search.

feb. 8, 2013 -- mlpack 1.0.4

• 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<<. See #164.
• Change return type of GMM::Estimate() to double (#266).
• Style fixes for k-means and RADICAL.
• Handle size_t support correctly with Armadillo 3.6.2 (#267).
• Add locality-sensitive hashing (LSH), found in src/mlpack/methods/lsh/.
• Better tests for SGD (stochastic gradient descent) and NCA (neighborhood components analysis).

sep. 16, 2012 -- mlpack 1.0.3

• 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 (#254), including stochastic gradient descent (#258).

aug. 15, 2012 -- mlpack 1.0.2

• 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/ (#156)
• Better reporting of boost::program_options errors (#231).
• Fix for timers on Windows (#218, #217).
• Fix for allknn and allkfn output (#210).
• Sparse coding dictionary initialization is now a template parameter (#226).

mar. 3, 2012 -- mlpack 1.0.1

• Added kernel principal components analysis (kernel PCA), found in src/mlpack/methods/kernel_pca/ (#47).
• Fix for Lovasz-Theta AugLagrangian tests (#188).
• Fixes for allknn output (#191, #192).
• Added range search executable (#198).
• Adapted citations in documentation to BiBTeX; no citations in -h output (#201).
• Stop use of 'const char*' and prefer 'std::string' (#183).
• Support seeds for random numbers (#182).

dec. 17, 2011 -- mlpack 1.0.0

• Initial release. See any resolved tickets numbered less than #196 or execute this query.
