WebAug 28, 2024 · The closer MAE is to 0, the more accurate the model is. But MAE is returned on the same scale as the target you are predicting for and therefore there isn’t a general rule for what a good score is. How good your score is can only be evaluated within your dataset. MAE can, however, be developed further by calculating the MAPE (Mean Absolute ...
