[mlpack-git] [mlpack/mlpack] mlpack 2.1.0

[Ryan Curtin]

Released Oct. 31st, 2016.

  * Fixed CoverTree to properly handle single-point datasets.
  * Fixed a bug in CosineTree (and thus QUIC-SVD) that caused split failures for some datasets (#717).
  * Added `mlpack_preprocess_describe` program, which can be used to print statistics on a given dataset (#742).
  * Fix prioritized recursion for k-furthest-neighbor search (`mlpack_kfn` and the `KFN` class), leading to orders-of-magnitude speedups in some cases.
  * Bump minimum required version of Armadillo to 4.200.0.
  * Added simple Gradient Descent optimizer, found in `src/mlpack/core/optimizers/gradient_descent/` (#792).
  * Added approximate furthest neighbor search algorithms QDAFN and DrusillaSelect in `src/mlpack/methods/approx_kfn/`, with command-line program `mlpack_approx_kfn`.
