Hi
@Afif
,
The Absolute error i
s the difference between the predicted value and the “true” value.
The Means Absolute Error MAE takes the average of absolute errors for a group of predictions and observations

Hi
@Afif
,
Yes, this is the same value. As stated in the
documentation
, the absolute error is calculated by summing the differences between the labels and predictions, and dividing this value by the number of examples.

Yes, it is the MAE formula. I've also done just a quick check where I performed the calculation manually and it matches.
