Robust learning of Huber loss under weak conditional moment

WebIn this paper, we propose a robust and non-convex p -Huber loss function based on the Huber loss. In the numerical analysis, the fitting effect of regression learning algorithm based on p -Huber loss and regression algorithm based on L1 loss, Huber loss and MCCR loss are compared.

However, these methods have limitations as they utilize the squared loss function, which are not robust to outliers and heavy-tailed errors, and the sub-Gaussian assumption may not be realistic in many practical situations. 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 magnitude higher than delta are not squared [1]. …
