Generalized Huber Loss for Robust Learning and its Efficient

WebNow let’s run our first robust regression. Robust regression is done by iterated re-weighted least squares (IRLS). The command for running robust regression is rlm in the MASS package. There are several weighting functions that can be used for IRLS. We are going to first use the Huber weights in this example. WebThis article is partially a review and partially a contribution. The classical two approaches to robustness, Huber’s minimax and Hampel’s based on influence functions, are reviewed with the accent on distribution classes of a non-neighborhood nature.

Web24 okt. 2013 · Some robust cost functions such as Huber [ 11] have been proposed to reduce errors introduced by outliers. Unlike normal least square in which the error has a quadratic influence on the cost function, the Huber function makes cost increase linearly if the error exceeds a certain threshold. This means that it weighs large error less. Web4 nov. 2024 · Image source: Created by the author Theil-Sen estimator.
