Witryna17 gru 2024 · Log-Cosh是比 L2 更光滑的损失函数，是误差值的双曲余弦的对数 L(y, f(x)) = n ∑ i = 1logcosh(y − f(x)) 其中， y 为真实值， f(x) 为预测值。 对于较小的误差 ∣y − f(x)∣ ，其近似于MSE，收敛下降较快；对于较大的误差 ∣y − f(x)∣ 其近似等于 ∣y − f(x) ∣ − log(2) ,类似于MAE，不会受到离群点的影响。 Log-Cosh具有Huber 损失的所有有点，且不 … Witryna1 1. weight ( Tensor, optional) – a manual rescaling weight given to each class. If given, it has to be a Tensor of size C. Otherwise, it is treated as if having all ones. size_average ( bool, optional) – Deprecated (see reduction ).
