Web10 okt. 2014 · What you're aksing is basically for a smoothed method for $ {L}_{1} $ Norm. The most common smoothing approximation is done using the Huber Loss Function. Its gradient is known ans replacing the $ {L}_{1} $ with it will result in a smooth objective function which you can apply Gradient Descent on. WebMax Huber famously set forth the classic definition of sovereignty in the 1928 Island of Palmas arbitration: “Sovereignty in the relations between States signifies independence. Independence in regard to a portion of the globe is the right to exercise therein, to the exclusion of any other State, the functions of a State.”

WebA smooth primal allows you to use gradients instead of subgradients and in turn allows you to apply gradient methods with appropriate stopping rules and such. A strongly convex primal leads to a proximal mapping of the primal objective which is not only non-expansive but contractive which is favorable for proximal-splitting methods.

Also it is not smooth at zero, which may or may not be a problem, depending on what it is used for.

The Huber operation computes the Huber loss between network predictions and target values for regression tasks. When the 'TransitionPoint' option is 1, this is also known as smooth L1 loss.
