An API for machine learning#

Machine learning functionalities.

This module proposes many high-level functions for creating and loading machine learning models.

create_classification_model(name, data, transformer=mappingproxy({'inputs': <gemseo.mlearning.transformers.scaler.min_max_scaler.MinMaxScaler object>}), **parameters)[source]
