Perpetual Documentation

Perpetual is a self-generalizing gradient boosting machine that doesn’t need hyperparameter optimization. It is designed to be easy to use while providing state-of-the-art predictive performance.

Key Features

• Self-Generalizing: No need for complex grid searches or Bayesian optimization.

• Efficient: Built in Rust with a zero-copy Python interface.

• Versatile: Supports regression, classification, and ranking.

• Interpretable: Built-in support for SHAP-like contributions and partial dependence plots.
