# Awesome Machine Learning with Ruby [<img src="ruby.jpg" align="left" width="30px" height="30px" />][ruby]

> Curated List of Ruby Machine Learning Links and Resources

[Machine Learning][ml] is a field of [Computational Science][cs] -
often nested under [AI][ai] research - with many practical
applications due to the ability of resulting algorithms to
systematically implement a specific solution without explicit
programmer's instructions. Obviously many algorithms need a definition
of [features][fe] to look at or a biggish [training set][ts] of data to derive the
solution from.

This curated list comprises [_awesome_][awesome] libraries,
data sources, tutorials and presentations about [Machine Learning][ml]
utilizing the [Ruby][ruby] programming language.

A lot of useful resources on this list come from the development by
[The Ruby Science Foundation][sciruby], our [contributors][contributors] and
our own day to day work on various ML applications.

:sparkles: Every [contribution](contributing.md) is welcome! Add links through pull
requests or create an issue to start a discussion.
