Web12 dec. 2024 · As discussed at the end of this section, all these estimators can locally exhibit robustness properties similar to the robust estimators of location since (10) represents the first-order conditions of a weighted location estimator and ψ(⋅) can be chosen to be the derivative of Huber's or Tukey's loss functions, for instance, as discussed in Section 1.1. Web26 jan. 2024 · Huber and logcosh loss functions. Huber loss is like a “patched” squared loss that is more robust against outliers. For small errors, it behaves like squared loss, but for large errors, it behaves like absolute loss: Huber ( x) = { 1 2 x 2 for x ≤ δ, δ x − 1 2 δ 2 otherwise. where δ is an adjustable parameter that controls ...

WebLAD loss function for relatively large errors. Furthermore, in the limit c !1, the loss function reduces to LS-loss ⇢ c (x)=1 2 x 2. Huber’s loss function is convex and differ-entiable, and the derivative of the loss function, c (x)= (x, for x c csign(x), for x >c, will be referred to as the score function in the sequel.
