WebIntroduction. Huber regression ( Huber 1964) is a regression technique that is robust to outliers. The idea is to use a different loss function rather than the traditional least-squares; we solve. This function is identical to the least squares penalty for small residuals, but on large residuals, its penalty is lower and increases linearly ... Web23 apr. 2024 · The Tukey loss function. The Tukey loss function, also known as Tukey’s biweight function, is a loss function that is used in robust statistics.Tukey’s loss is similar to Huber loss in that it demonstrates quadratic behavior near the origin. However, it is even more insensitive to outliers because the loss incurred by large residuals is constant, … WebNMPC based on Huber penalty functions to handle large deviations of quadrature states . × Close Log In.
