autoprognosis.plugins.prediction.regression.plugin_bayesian_ridge module

class BayesianRidgePlugin(n_iter: int = 1000, tol: float = 0.001, hyperparam_search_iterations: Optional[int] = None, model: Optional[Any] = None, random_state: int = 0, **kwargs: Any)

Bases: autoprognosis.plugins.prediction.regression.base.RegressionPlugin

Bayesian ridge regression.

Parameters

• n_iter – int Maximum number of iterations. Should be greater than or equal to 1.

• tol – float Stop the algorithm if w has converged.

• random_state – int Random seed

Example

>>> from autoprognosis.plugins.prediction import Predictions
>>> plugin = Predictions(category="regression").get("bayesian_ridge")
>>> from sklearn.datasets import load_iris
>>> X, y = load_iris(return_X_y=True)
>>> plugin.fit_predict(X, y)
