mlpack

A fast C++ machine learning library, also usable from Python, R, Julia, Go and the command line.

New this week

What it does

mlpack is a machine learning library written in C++. Its makers describe it as a 'swiss army knife' of machine learning methods for researchers.

Because it is lightweight, it suits production systems, but it can also be used for quick experiments. Besides C++, it offers command-line programs and links for Python, Julia, Go and R.

Who it's for

Programmers and researchers who need fast machine learning, especially in C++.
