class pyreal.explanation_types.feature_based.FeatureImportanceExplanation(explanation, values=None)[source]#

A type wrapper for global feature importance FeatureBased type outputs from explanation algorithms. Global feature importance explanations give one numeric value per feature, representing that feature’s overall importance to the model’s prediction.

__init__(explanation, values=None)#

Set the wrapped explanation to explanation and values to values and validate :param explanation: wrapped explanation :type explanation: object :param values: Values corresponding with the object being explained :type values: DataFrame of shape (n_instances, n_features) or None
