Proximal operator
text:
In mathematical optimization, the proximal operator is an operator associated with a proper, lower semi-continuous convex function f from a Hilbert space X to [ − ∞ , + ∞ ] , and is defined by: For any function in this class, the minimizer of the right-hand side above is unique, hence making the proximal operator well-defined. The proximal operator is used in proximal gradient methods, which is frequently used in optimization algorithms associated with non-differentiable optimization problems su
