Huber Error Loss Functions - Medium

In statistics, the Huber loss is a loss function used in robust regression, that is less sensitive to outliers in data than the squared error loss. A variant for classification is also sometimes used. Ver mais The Pseudo-Huber loss function can be used as a smooth approximation of the Huber loss function. It combines the best properties of L2 squared loss and L1 absolute loss by being strongly convex when close to the … Ver mais • Winsorizing • Robust regression • M-estimator • Visual comparison of different M-estimators Ver mais For classification purposes, a variant of the Huber loss called modified Huber is sometimes used.

WebSmooth L1 loss is closely related to HuberLoss, being equivalent to huber (x, y) / beta huber(x,y)/beta (note that Smooth L1’s beta hyper-parameter is also known as delta for Huber). This leads to the following differences: As beta -> 0, Smooth L1 loss converges to L1Loss, while HuberLoss converges to a constant 0 loss.
