About: A scalable, fast C++ machine learning library, with emphasis on usability.

Changes:
  • 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).

About: Armadillo is a template C++ linear algebra library aiming towards a good balance between speed and ease of use, with a function syntax similar to MATLAB. Matrix decompositions are provided through optional integration with LAPACK, or one of its high performance drop-in replacements (eg. Intel MKL, OpenBLAS).

Changes:
  • added matrix exponential function: expmat()
  • faster .log_p() and .avg_log_p() functions in the Gaussian mixture model class
  • faster handling of in-place addition/subtraction of expressions with an outer product
  • workaround for a bug in GCC 4.4
