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