Webhuber is useful as a loss function in robust statistics or machine learning to reduce the influence of outliers as compared to the common squared error loss, residuals with a … The Huber loss function describes the penalty incurred by an estimation procedure f. Huber (1964) defines the loss function piecewise by [1] This function is quadratic for small values of a, and linear for large values, with equal values and slopes of then different sections at the two points where . 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 The Huber loss function is used in robust statistics, M-estimation and additive modelling.
