Apparatus Machine Learning Routines

Apparatus is an abandoned Node.js package (last updated in 2012, current version 0.0.10) providing a collection of low-level machine learning algorithms. It focuses on numerical input, primarily arrays of numbers and vectors, and is not designed for direct text or natural language processing. Instead, it serves as a foundational library for other projects like the 'natural' package, which adds a layer of text feature extraction. Due to its age, it primarily uses CommonJS modules and is not compatible with modern Node.js ESM-only environments without transpilation or specific configuration. Its lack of maintenance means it should be approached with caution for new projects.
