Some researchers have recommended the use of the Mean Absolute Error (MAE) instead of the Root Mean Square Deviation. MAE possesses advantages in interpretability over RMSD. MAE is the average of the absolute values of the errors. MAE is fundamentally easier to understand than the square root of the average of squared errors. Furthermore, each error influences MAE in direct proportion to the absolute value of the error, which is not the case for RMSD.

How to Calculate the Sum of Squares for Error (SSE)

WebWhy do we use the square loss. The squared error forces $h(x)$ and $y$ to match.

WebJan 27, 2015 · In my personal opinion, I think folks like L-2 norm (aka energy optimal, aka least squared error) because it is simple, easy to explain, easy to execute, has the property of doing more work against bigger errors than smaller ones, and leaves with zero bias. Consider h-infinity norms where the variance is minimized and bias is constrained but ... WebYou could view this part as a mean of the squared errors and now we're gonna take the square root of it.
