WebApr 5, 2024 · 1. Short answer: Yes, you can and should always report (test) MAE and (test) MSE (or better: RMSE for easier interpretation of the units) regardless of the loss function you used for training (fitting) the model. Long answer: The MAE and MSE/RMSE are measured (on test data) after the model was fitted and they simply tell how far on … WebFeb 14, 2024 · Hampel has written somewhere that Huber's M-estimator (based on Huber's loss) is optimal in four respects, but I've forgotten the other two.
