We propose a generalized formulation of the Huber loss. We show that with a suitable function of choice, specifically the log-exp transform; we can achieve a loss function which combines the desirable properties of both the absolute and the quadratic loss. We provide an algorithm to find the minimizer of such loss functions and show that finding a centralizing metric is not that much harder than the traditional mean and median.
翻译:我们建议对Huber损失作广义的表述。我们表明,如果有合适的选择功能,具体来说就是日志表达变换;我们可以实现一种将绝对损失和二次损失的适当特性结合起来的损失功能。我们提供了一种算法,以找到这种损失功能的最小性,并表明找到集中化指标并不比传统的平均值和中位值难得多。
