Mean Absolute Error - measure of distance between two numerical targets.

Used for regression problems.

MAE = \frac{\sum_{i=1}^n | \mathbf{y}_i - \mathbf{\hat{y}}_i |}{n},

where \mathbf{y}_i and \mathbf{\hat{y}}_i are the target values or prediction respectively for a particular data sample i (both multidimensional in case of using multiple targets) while n is the number of samples we consider during the scoring.
