seldonian.models.objectives.False_Positive_Rate

False_Positive_Rate(model, theta, X, Y, **kwargs)

Calculate probabilistic mean false positive rate over the whole sample. This has slightly different meanings depending on binary vs. multi-class setting.

Parameters:

• model – SeldonianModel instance

• theta (numpy ndarray) – The parameter weights

• X (numpy ndarray) – The features

• Y (numpy ndarray) – The labels

Returns:

mean false positive rate

Return type:

float between 0 and 1
