NettetLinear Regression Line for MAE Loss Function with a more irregular pattern. This is due to fact that MAE will penalize the algorithm based on the difference only (unlike the square of the difference in MSE). In that case, as more and more data fits into a pattern, it tends to ignore rare patterns. Nettet18. jul. 2024 · I’ll introduce you to two often-used regression metrics: MAE and MSE.
