Web27 May 2024 · The smooth maximum function has both a defined gradient and Hessian, and in this post I derive them. I am using the logarithm-based definition of smooth-max, shown here: I will use the second variation above, ignoring function arguments, with the hope of increasing clarity. Applying the chain rule gives the ith partial gradient of smooth-max:

WebFinally, we specialize our result to nite minimax problems, i.e., min x max 1 i m fi(x ) where fi(x ) can be nonconvex function but each fi is a smooth function; nonconvex constrained opti-mization problems can be reduced to such nite minimax problems.
