WebMar 31, 2024 · 1 It is common to have root mean squared error (RMSE) greater on the test dataset than on the training dataset (this is equal to having accuracy/score higher for model in training dataset than test dataset). WebMAE will never be higher than RMSE because of the way they are calculated. They only make sense in comparison to the same measure of error: you can compare RMSE for Method 1 to RMSE for Method 2, or MAE for Method 1 to MAE for Method 2, but you can’t say MAE is better than RMSE for Method 1 because it’s smaller.
