平均绝对误差损失 Mean Absolute Error Loss基本形式与原理 平均绝对误差 Mean Absolute Error (MAE) 是另一类常用的损失函数,也称为 L1 Loss。其基本形式如下 同样的我们可以对这个损失函数进行可视化如下图,MAE 损失的最小值为 0(当预测等于真实值时),最大值为无穷大。可以看到随着预测与真实值绝对误差的增加,M...

Describe the bug From my understanding, currently there is no way to minimize the MAE (Mean Absolute Error). Quantile regression with quantile=0.5 will optimize for the Median Absolute Error. This would be different from optimizing the M...

We study in this paper the consequences of using the Mean Absolute Percentage Error (MAPE) as a measure of quality for regression models. We show that finding the best model under the MAPE is equivalent to doing weighted Mean Absolute Error (MAE) regression. We show that universal consistency...
inflating or increasing the mean error value due to the square of the error value.In MAE, different errors are not weighted more or less, but the scores increase linearly with the increase in errors. The MAE score is measured as the average of the absolute error values. The Absolute is a...
