An API for machine learning

Machine learning functionalities.

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

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

Create a classification model from a learning dataset.

Parameters:

• name (str) – The name of the classification algorithm.

• data (IODataset) – The learning dataset.

• transformer (TransformerType) –

  The strategies to transform the variables. Values are instances of Transformer while keys are names of either variables or groups of variables. If IDENTITY, do not transform the variables.

  By default it is set to {‘inputs’: <gemseo.mlearning.transformers.scaler.min_max_scaler.MinMaxScaler object at 0x7f8bdddd6970>}.

• parameters – The parameters of the classification model.

Returns:

A classification model.

Return type:

MLClassificationAlgo
