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 For classification purposes, a variant of the Huber loss called modified Huber is sometimes used. Given a prediction Meer weergeven • Winsorizing • Robust regression • M-estimator Meer weergeven 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 … Meer weergeven The Huber loss function is used in robust statistics, M-estimation and additive modelling.

WebThis is often referred to as Charbonnier loss [5], pseudo-Huber loss (as it resembles Huber loss [18]), or L1-L2 loss [39] (as it behaves like L2 loss near the origin and like L1 loss elsewhere). Our loss’s ability to express L2 and smoothed L1 losses is sharedby the “generalizedCharbonnier”loss[34], which Webhqreg-package Regularization Paths for Lasso or Elastic-net Penalized Huber Loss Regression and Quantile Regression Description Efficient algorithms for fitting regularization paths for lasso or elastic-net penalized regression mod-els with Huber loss, quantile loss or squared loss.

Still, we can say it stays neutral for all range of values. When to use HuberLoss: As said earlier that Huber loss has both MAE and MSE. So when we think higher weightage should not be given to outliers, go for Huber.
