Tribuo 4.3.0 API

Tribuo is a library for building and deploying Machine Learning models. It provides classification, regression, clustering, anomaly detection and multi-label classification algorithms. Tribuo is strongly typed, with most of the relevant types living in the org.tribuo package. Task specific types live in the root package of that task (e.g., org.tribuo.classification). Tribuo is modular, each package/module is scoped to have minimal dependencies, and there are few cross-cutting packages. Tribuo's development is lead by Oracle Labs' Machine Learning Research Group, the source is hosted on Github, and more documentation is available on the project website tribuo.org.
