The 2013 JMLR paper by Ryan R. Curtin, James R. Cline, N. P. Slagle, William B. March, Parikshit Ram, Nishant A. Mehta, and Alexander G. Gray presented MLPACK as a scalable, multi-platform C++ library with a simple API for new users and high-performance flexibility for expert users. ### Project history The project grew into a broader scientific-computing library and community. A 2018 OpenReview workshop paper described mlpack as emphasizing speed and flexibility and implementing a wide variety of machine-learning algorithms. The 2023 JOSS paper for mlpack 4 marked a major technical milestone: a fast, header-only C++ library release with authorship spanning the expanded contributor community. ### How it is used In practice mlpack is used either as a C++ library, commonly by including `` and linking against Armadillo, or through command-line programs and bindings for Python, Julia, Go, and R. Its own README describes the project as a machine-learning analogue to LAPACK and as a "swiss army knife" for machine-learning researchers, while the homepage names Armadillo, ensmallen, and cereal as core foundations. In package-manager ecosystems it occupies the intersection of scientific C++ development library and installed algorithm CLI suite, with Homebrew exposing many `mlpack_*` executables for common methods such as k-means, PCA, nearest-neighbor search, random forests, regression, and preprocessing. ### Sources -
