mean_absolute_error()

audmetric.mean_absolute_error(truth, prediction)

Mean absolute error.

$$\text{MAE} = \frac{1}{n} \sum^n_{i=1} |\text{prediction} - \text{truth}|$$

Parameters

• truth (Sequence[float]) – ground truth values

• prediction (Sequence[float]) – predicted values

Return type

float

Returns

mean absolute error

Raises

ValueError – if truth and prediction differ in length

Examples

>>> mean_absolute_error([0, 0], [0, 1])
0.5
