WrapperPipeline

基类: SearchSpace

        This search space is for wrapping a sklearn estimator with a method that takes another estimator and hyperparameters as arguments.

        """


        self.estimator_search_space = estimator_search_space
        self.method = method
        self.space = space

    def generate(self, rng=None):

        return WrapperPipelineIndividual(method=self.method, space=self.space, estimator_search_space=self.estimator_search_space, hyperparameter_parser=self.hyperparameter_parser, wrapped_param_name=self.wrapped_param_name,  rng=rng)

__init__(method, space, estimator_search_space, hyperparameter_parser=None, wrapped_param_name=None)

此搜索空间用于包装一个sklearn估计器,该方法接受另一个估计器和超参数作为参数。 例如,这可以与sklearn.ensemble.BaggingClassifier或sklearn.ensemble.AdaBoostClassifier一起使用。
