Fixed point operator

WebFinally, the fixed points of the proximal operator of f are pre-cisely the minimizers of f(we will show this in §2.3). In other words, proxλf(x⋆) = x⋆ if and only if x⋆ minimizes f. This implies a close connection between proximal operators and fixed point theory, and suggests that proximal algorithms can be interpreted as solving opti- WebAug 29, 2024 · To define a working fixed point operator, just use recursion e.g. fix f = f (fix f) (more efficient ones exist, but this is the simplest). – chi Aug 29, 2024 at 18:20
