Concretely, we make two main contributions: 1) We present new observations and insightful analysis about mean absolute error (MAE), which is theoretically proved to be noise-robust. First, we reveal its underfitting problem in practice when severe noise exists. Second, we conclude its noise-...
Mean Absolute Error in R, when we do modeling always need to measure the accuracy of the model fit. The mean absolute error (MAE) allows us to measure the accuracy of a given model. The formula for mean absolute error is MAE = (1/n) * Σ|yi – xi| where: Σ symbol Indicate that...

The problem of finding the minimizer of the rth -mean error, is revisited, via a unified approach. The approach is discussed for arbitrary r and is illustrated for r = 1 (mean absolute error)r = 2 (mean squared error), and r = 4. This approach is also discussed in the context of ...
The design of optimal PSHs under the mean absolute error (MAE) criterion is shown to be similar to the minimum MAE stack filtering theory. The only difference is that one needs now to design more than one stack filter that together construct an optimal PSF. As a result, while reviewing ...
