Gets the absolute loss of the model.

member this.MeanAbsoluteError : double
Public ReadOnly Property MeanAbsoluteError As Double

Property Value

Double

Remarks

The absolute loss is defined as $L1 = \frac{1}{m} \sum_{i = 1}^m | y_i - \hat{y}_i |$, where $m$ is the number of instances in the test set, $\hat{y}_i$ are the predicted labels for each instance, and $y_i$ are the correct labels of each instance.

L1 loss is a non-negative, decreasing metric. Smaller values indicate a better model with respect to this metric.
