So the question is why is your training MSE higher in your first case. I would counter this question by asking, is it really significantly higher? 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.
