WebIn this paper, we first introduce the truncated Huber penalty function which shows strong flexibility under different parameter settings. A generalized framework is then proposed … WebLiu et al. [21] introduced the truncated Huber penalty function to make their generalized model with strong flexibility, and superiorly realized the smoothing tasks of four groups of applications. Recently, a new global method [22] was proposed that embedded the bilateral filter in the least squares model for efficient edge-preserving smoothing.

That is the case with the hqreg, where the whole loss function is changed to the Huber loss function, you can still add a penalization term to that loss function which would regularize it.
