WebI have very rough ideas for some: MAD if a deviation of 2 is "double as bad" than having a deviation of 1. RMSE if the value deteriorates more quickly - punishes outliers hard! WebSep 26, 2024 · This is to say that large differences between actual and predicted are punished more in MSE than in MAE. The following picture graphically demonstrates what an individual residual in the MSE might look like. Outliers will produce these exponentially larger differences, and it is our job to judge how we should approach them. The problem of …
