mae_measure module

The mean absolute error to measure the quality of a regression algorithm.

The mean absolute error (MAE) is defined by


where \(\hat{y}\) are the predictions and \(y\) are the data points.

class gemseo_mlearning.quality_measures.mae_measure.MAEMeasure(algo, fit_transformers=False)[source]

Bases: MLErrorMeasure

The mean absolute error measure for machine learning.

  • algo (MLRegressionAlgo) – A machine learning algorithm for supervised learning.

  • fit_transformers (bool) –

    Whether to re-fit the transformers when using resampling techniques. If False, use the transformers of the algorithm fitted from the whole learning dataset.

    By default it is set to False.

algo: MLAlgo

The machine learning algorithm usually trained.
