Huber robust error function
Web1 jan. 2003 · We propose to minimize the Huber function with a quasi-Newton method that has the potential of being faster and more robust than conjugate-gradient methods when solving nonlinear problems. Tests with a linear inverse problem for velocity analysis with both synthetic and field data suggest that the Huber function gives far more robust … WebTo tackle the problem, the pseudo-Huber loss function, ... of the pseudo-Huber loss to train the MLP as the sudden change in weather patterns can result in large modeling errors. …

Web13 apr. 2024 · The above \(\varphi\) function is the Huber loss function, and the tuning constant generally selected, \(c=\) 1.345, is the bound constraining large errors. Its value is determined by bounding the influence of residuals in the Huber estimator, or the influence of both residuals and explanatory variables in other robust estimators, like in Hampel et al. (). Web29 jun. 2024 · A robust regression effectively performs a weighted regression such that extreme observations carry less weight upon the overall effect, compared to non-extreme observations. Both Stata and R can perform robust regression using the same kinds of weights: > Two types of weights are used.
