About: A scalable, fast C++ machine learning library, with emphasis on usability. Changes:Fixed CoverTree to properly handle singlepoint datasets.  Fixed a bug in CosineTree (and thus QUICSVD) 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 kfurthestneighbor search (mlpack_kfn and the KFN class), leading to ordersofmagnitude 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 commandline program mlpack_approx_kfn.

About: Armadillo is a high quality C++ linear algebra library, aiming towards a good balance between speed and ease of use. The function syntax is deliberately similar to MATLAB. Useful for algorithm development directly in C++, or quick conversion of research code into production environments (eg. software & hardware products). Changes:

About: The SHOGUN machine learning toolbox's focus is on large scale learning methods with focus on Support Vector Machines (SVM), providing interfaces to python, octave, matlab, r and the command line. Changes:This release features the work of our 8 GSoC 2014 students [student; mentors]:
It also contains several cleanups and bugfixes: Features

About: OpenGM is a free C++ template library, a command line tool and a set of MATLAB functions for optimization in higher order graphical models. Graphical models of any order and structure can be built either in C++ or in MATLAB, using simple and intuitive commands. These models can be stored in HDF5 files and subjected to stateoftheart optimization algorithms via the OpenGM command line optimizer. All library functions can also be called directly from C++ code. OpenGM realizes the Inference Algorithm Interface (IAI), a concept that makes it easy for programmers to use their own algorithms and factor classes with OpenGM. Changes:Initial Announcement on mloss.org.
