autoprognosis.plugins.prediction.classifiers.plugin_gaussian_naive_bayes module

class GaussianNaiveBayesPlugin(calibration: int = 0, random_state: int = 0, model: Optional[Any] = None, **kwargs: Any)

Bases: autoprognosis.plugins.prediction.classifiers.base.ClassifierPlugin

Classification plugin based on the Gaussian Naive Bayes algorithm for classification.

Method:

The plugin implements the Gaussian Naive Bayes algorithm for classification. The likelihood of the features is assumed to be Gaussian.

Parameters

  • calibration – int Enable/disable calibration. 0: disabled, 1 : sigmoid, 2: isotonic.

  • random_state – int, default 0 Random seed

Example

>>> from autoprognosis.plugins.prediction import Predictions
>>> plugin = Predictions(category="classifiers").get("gaussian_naive_bayes")
>>> plugin.fit_predict(...)
