HUBER FUNCTION REGRESSION - Stanford University
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 target/minimum and less steep for extreme values. The scale at which the Pseudo … Meer weergeven 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. Meer weergeven • Winsorizing • Robust regression • M-estimator • Visual comparison of different M-estimators Meer weergeven For classification purposes, a variant of the Huber loss called modified Huber is sometimes used. Given a prediction Meer weergeven The Huber loss function is used in robust statistics, M-estimation and additive modelling.
