mlpack 1.0.3

Released September 16th, 2012.

• 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).

mlpack 1.0.2

Released August 12th, 2012.

• 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).

mlpack 1.0.11

Released December 11th, 2014.

• Proper handling of dimension calculation in PCA.
• Load parameter vectors properly for LinearRegression models.
• Linker fixes for AugLagrangian specializations under Visual Studio.
• Add support for observation weights to LinearRegression.
• MahalanobisDistance<> now takes root of the distance by default and therefore satisfies the triangle inequality (TakeRoot now defaults to true).
• Better handling of optional Armadillo HDF5 dependency.
• Fixes for numerous intermittent test failures.
• math::RandomSeed() now sets the seed for recent (>= 3.930) Armadillo versions.
• Handle Newton method convergence better for SparseCoding::OptimizeDictionary() and make maximum iterations a parameter.
• Known bug: CosineTree construction may fail in some cases on i386 systems (376).

mlpack 1.0.10

Released August 29th, 2014.

• Bugfix for NeighborSearch regression which caused very slow allknn/allkfn. Speeds are now restored to approximately 1.0.8 speeds, with significant improvement for the cover tree (#365).
• Detect dependencies correctly when ARMA_USE_WRAPPER is not defined (i.e., libarmadillo.so does not exist).
• Bugfix for compilation under Visual Studio (#366).

mlpack 1.0.1

Released March 3rd, 2012.

• 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).

mlpack 1.0.0
