Smooth Abs Function at Sheila Hatchell blog

Smooth Abs Function. I've thought about working with exponentials. F(y) ≥ f(x) + ∇f(x)t (y − x)). Are there any good approximations of the absolute value function which are $c^2$ or at least $c^1$? As you and others have mentioned, functions of the form $\sqrt{x^2 + 4\mu^2}$ can be a good approximation to $\left|x\right|$ and are standard in many optimization. Smoothed mathematical functions¶ the functions in this section are smoothed equivalents of the original math functions and can be used to allow computing derivatives around. In short, a numerically stable smooth absolute value function is: Smooth convex functions always lie below a parabola. Smoothness tells us that the gradient can’t change too quickly, so if the gradient is large somewhere and we move in that direction or its. Convex functions always lie above their tangent lines (i.e.
