criterion module¶
Combination of the expectation and standard deviation of the regression model.
Statistics:
Estimator:
- class gemseo_mlearning.adaptive.criteria.mean_std.criterion.MeanSigma(algo_distribution, kappa)[source]
Bases:
MLDataAcquisitionCriterion
Combination of the expectation and standard deviation of the regression model.
This criterion is scaled by the output range.
Initialize self. See help(type(self)) for accurate signature.
- Parameters:
algo_distribution (MLRegressorDistribution) – The distribution of a machine learning algorithm.
kappa (float) – A factor associated with the standard deviation to increase or decrease the mean value.
- algo_distribution: MLRegressorDistribution
The distribution of a machine learning algorithm assessor.
- force_real: bool
Whether to cast the results to real value.
- has_default_name: bool
Whether the name has been set with a default value.
- kappa: float
The factor associated with the standard deviation to increase the mean value.
- last_eval: OutputType | None
The value of the function output at the last evaluation.
None
if it has not yet been evaluated.
- output_range: float
The output range.
- special_repr: str
The string representation of the function overloading its default string ones.
