The ml.js organization on GitHub was created in October 2014 in the group of Luc Patiny at EPFL. It provides machine learning, statistics and numerical analysis in JavaScript, for the browser and Node.js: matrices and linear algebra, regression, clustering, classification, dimensionality reduction, and signal and spectra processing.
It contains 112 public repositories and 118 packages published on npm, downloaded 48,082,689 times in September 2026 and 431,139,748 times in the last 12 months (October 2025 to September 2026). Many of these packages are currently maintained by Zakodium Sàrl.
