Huber Loss是一种将MSE与MAE结合起来,取两者优点的损失函数,也被称作Smooth Mean Absolute Error Loss 。其原理很简单,就是在误差接近0时使用MSE,误差较大时使用MAE,公式为: J_{\text {huber}}=\frac{1}{N} \sum_{i=1}^{N} \mathbb{I}_{\left|y_{i}-\hat{y}_{i}\right| \leq \delta} \...
其原理很简单,就是在误差接近 0 时使用 MSE,误差较大时使用 MAE,公式为 上式中是 Huber Loss 的一个超参数,的值是 MSE 和 MAE 两个损失连接的位置。上式等号右边第一项是 MSE 的部分,第二项是 MAE 部分,在 MAE 的部分公式为是为了保证误差时 MAE 和 MSE 的取值一致,进而保证 Huber Loss 损失连续可导...
