WebJan 15, 2013 · It is true that the median is more robust (subject to outliers) than the mean. My understanding is that the reason statistics tends to use the mean (and squared errors for that matter) is that in the long run, on average, assuming symmetrical distributions, they … WebAug 27, 2024 · MAE is a measure of model accuracy given on the same scale as the prediction target. Simply put, MAE can be interpreted as the average error that the model’s predictions have in comparison with their corresponding actual targets.
