A collection of command-line tools for machine learning and data mining tasks. These tools are well-suited for script-automated experiments. These tools cover a wide diversity of tasks, including supervised learning, dimensionality reduction, collaborative filtering, optimization, visualization, etc.

A GUI wizard tool is also included to assist the user to construct a command that will perform the desired task.

Each command-line tool is a thin wrapper around functionality in an object-oriented C++ class library. So, if you find one of the tools to be useful, you can also link its functionality into your code. The command-line tools may serve as demos for how to use the class library. Also, a collection of additional demo apps is included to exhibit some of the classes that are not exposed by the command-line tools.

The class library is distributed under the LGPL, and the code for most of the demo apps is public domain. Builds on 32 and 64 bit Linux, Windows, OSX, etc.

Version Changelog Date

Added support for CUDA GPU-parallelized neural network layers, and several other new features. Full list of changes at

July 20, 2014, 04:53:54

Changed the license from LGPL to CC0. Added classes for stackable autoencoders and restricted boltzmann machines. Polished up the GBayesianNetwork class and add examples and unit tests. Added support for CMake. Made the build process also support clang, and be more mac-friendly. Simplified some important classes, including GMatrix and GNeuralNet. Enforced const correctness in more places. Nixed most uses of smart pointers. Made all learning algorithms thread-safe. Added thread-parallelism to several ensemble methods. Added support for binary division trees. Added some common activation functions. Added a tool to generate a vector of meta statistics about a dataset. Added several small-but-useful tools. Simplified the docs and web site.
