A Python library for probabilistic prediction using natural gradient boosting, built on scikit-learn.
NGBoost is a Python library that implements Natural Gradient Boosting for probabilistic prediction, enabling machine learning models to output full probability distributions rather than single-point estimates. It solves the problem of uncertainty quantification in predictions by providing a scalable and modular framework built on scikit-learn.
Data scientists and machine learning practitioners who need probabilistic forecasts and uncertainty estimates in regression tasks, particularly those working with scikit-learn-based workflows.
Developers choose NGBoost for its efficient natural gradient boosting approach, which improves probabilistic prediction stability, and its seamless integration with scikit-learn, offering flexibility in scoring rules, distributions, and learners.

Uses natural gradients to stabilize and accelerate probabilistic boosting, improving convergence and reliability as detailed in the linked research paper.
Provides a familiar API that seamlessly fits into scikit-learn workflows, making adoption straightforward for existing machine learning pipelines.
Allows customization of scoring rules, distributions, and base learners, offering adaptability for diverse probabilistic forecasting needs.
Outputs full probability distributions instead of point estimates, enabling critical uncertainty quantification for risk-aware decision-making.
Adding new distributions or scoring rules requires manual implementation and deeper expertise, as highlighted in the user guide, which can be time-consuming.
Natural gradient computations introduce overhead, making training slower than traditional gradient boosting methods, especially on large datasets.
Default distributions and scoring rules may be insufficient for specialized applications, necessitating additional customization and learning effort.
