        • absolute_importance number

          A positive number showing how much the parameter influences the variation of the loss function. For hyperparameters with values that are not specified by the user but tuned during hyperparameter optimization.

        • name string Required
        • relative_importance number

          A number between 0 and 1 showing the proportion of influence on the variation of the loss function among all tuned hyperparameters. For hyperparameters with values that are not specified by the user but tuned during hyperparameter optimization.

        • supplied boolean Required

          Indicates if the hyperparameter is specified by the user (true) or optimized (false).

        • value number Required

          The value of the hyperparameter, either optimized or specified by the user.

      • total_feature_importance array[object]

        An array of the total feature importance for each feature used from the training data set. This array of objects is returned if data frame analytics trained the model and the request includes total_feature_importance in the include request parameter.

          • mean_magnitude number Required

            The average magnitude of this feature across all the training data. This value is the average of the absolute values of the importance for this feature.

          • max number Required

            The maximum importance value across all the training data for this feature.

          • min number Required

            The minimum importance value across all the training data for this feature.

        • classes array[object] Required

          If the trained model is a classification model, feature importance statistics are gathered per target class value.
