gaussian_process_regression

Gaussian process regression regressor supporting continuous and mixed-feature datasets using an exact mixed Gaussian process with posterior uncertainty estimates. Learns from a dataset object implementing the regression_dataset_protocol protocol and returns a regressor term that can be used for prediction, predictive-distribution queries, and export as predicate clauses.

Public predicates

.. index:: predict_distribution/3 .. _gaussian_process_regression/0::predict_distribution/3:

predict_distribution/3 ^^^^^^^^^^^^^^^^^^^^^^^^^^

Predicts the posterior predictive Gaussian distribution for a new instance using the learned regressor. The returned term has the shape gaussian(Mean, Variance) where Variance includes the learned observation noise variance.
